How to Write the University of Virginia Essays 2018-2019
The University of Virginia is a public research university founded in 1819 by Thomas Jefferson, making the institution a prominent historical site. Being a UNESCO World Heritage Site, UVA is well known for its historical foundation and early roots. Located in Charlottesville, Virginia, UVA is situated in a lively metropolitan community. Ranked by U.S. News and World Report at #3 among public schools and #25 overall, UVA is one of the nationââ¬â¢s top universities. In the 2016-2017 application cycle, UVA only admitted 27.4% of applicants, making admission quite competitive. In addition to academic transcripts and letters of recommendation, all applicants are required to submit an additional supplemental essay, with additional essays needed depending on your selected major. With such competitive rates, it is often intimidating to complete these additional essays. However, is here to offer our guide on how to tackle UVAââ¬â¢s 2018-2019 application! Required: Choose one of the following (250 words): Note that this essay is required; however, UVA gives you the option to choose between 4 prompts, all of which have a 250-word limit. Choose the essay that you feel a stronger connection to, as this will make for a much stronger and more personal essay. With that being said, letââ¬â¢s take a look at each of the following prompts. For this essay, avoid choosing a word thatââ¬â¢s generally self-explanatory or cliche. Example of this could be ââ¬Å"happinessâ⬠or ââ¬Å"loveâ⬠because these words are often overused and the meaning can generally be inferred without an additional story. You want to choose something that is both personally meaningful to you and something that is attached to a greater story. For instance, if you are multilingual and your grandmother would always offer you a specific piece of advice in another language, you could use a word related to that advice in that language. Perhaps there is a story attached to the reason why she gave you that advice, or perhaps it is what you remember the most from her. Tell a story around this idea and your essay will be much more personal and impactful. You could also show off your nerdy side here or highlight your interests. Perhaps your favorite word is ââ¬Å"emulsionâ⬠because it is relevant to your two favorite activities: chemistry and cooking. You could discuss your love for each of these subjects and, like the previous example, tell a brief story on how the word relates to your personal experiences. When choosing a word, you could also consider alternate meanings by considering meanings outside the traditional dictionary definition. In this case, you could contrast the traditional meaning with your own personal interpretation of the word in order to point out any differences and highlight your own personal connection to the word. Again, the key for this essay is to be personal. In terms of writing your essay, you want to make it clear what your word is without directly saying ââ¬Å"my favorite word is _____.â⬠; always start your essay with an interesting opener and a thoughtful conclusion. Since the essay is short at 250 words, you want to be fairly straightforward without being too stale or obvious. Chances are, you have a unique quality that makes up who you are. This essay is all about pinpointing that quality and describing it in terms of its importance to your identity. Perhaps you have an odd fascination with insects or you collect unconventional objects. This is a perfect essay to discuss these facets of your life. You must make sure to connect your quirk to your personality and individuality. Donââ¬â¢t simply describe the quirk; ask yourself why this quality is important to you and consider how your individuality would change had you not possessed this characteristic. You want to highlight your personality in this essay, whether it be through humorous writing or a creative story. For example, if your quirk is having to do a cartwheel every morning before school, you can write a story mapping out your day, with emphasis on your daily cartwheel. Perhaps this is the only way to get your blood pumping and prepare you for the day ahead. Perhaps doing cartwheels ensures that you always start your day with a positive attitude, allowing you to tackle any obstacles during the day. There are endless possibilities for quirks you could write about, as each person is different and has unique habits. Your quirk could be a unique mannerism such as a ââ¬Å"weirdâ⬠laugh or a unique daily routine you have. Perhaps your quirk was the object of ridicule in your earlier years, but now youââ¬â¢ve become confident in yourself and your unique qualities. Show UVA what makes you you and how proud you are to be yourself ââ¬â weird quirks and all! For this essay, you want to consider your interests and how you want to share these interests with others. Your Flash Seminar should reflect something youââ¬â¢re passionate about, yet also be unique enough to not already exist. For example, you donââ¬â¢t want to create a seminar about something like ââ¬Å"Cell Biologyâ⬠or ââ¬Å"Classical Literature.â⬠For instance, if you love science and have always been intrigued by astrology, you could create a Flash Seminar called ââ¬Å"Is there a Scientific Basis for Astrology?â⬠If you love politics and are passionate about film, you could create a seminar called ââ¬Å"Hidden Political Messages in Modern Film.â⬠With any topic you choose, make sure to explain your choice. Why are you passionate about the topic and why do you think there should be a discussion about it? Perhaps you want to share your passions with others through a unique perspective or perhaps your proposed question has puzzled you in the past, making you eager to hear the thoughts of others. Discuss your reasons for creating the class and the goals you hope the class achieves. Like the previous question, you want to consider the topics youââ¬â¢re passionate about and want to share with others. You could interpret ââ¬Å"messageâ⬠as a form of artwork such as a painting, or you can interpret it more literally as a message or phrase. For instance, if youââ¬â¢re passionate about redesigning the roles of modern women, you could describe a painting that includes a dichotomy between traditional and more progressive roles of women. Perhaps half the painting includes black and white images of women performing household tasks and the other half uses vivid colors to portray women in positions of power and independence. Maybe youââ¬â¢ve been empowered by several strong women in your life and want to advocate for gender issues such as equal pay. Maybe there is a quote or phrase from a novel that youââ¬â¢ve read that stuck out to you and want to share with UVAââ¬â¢s student body. For instance, if a quote from Thi Buiââ¬â¢s The Best We Could Do resonates with you due to a similarity with your immigration story, you could paint this message on the Beta Bridge in order to create a sense of community with those who share similar backgrounds. No matter what you choose to paint, make sure you have a personal connection to the art. Ensure that you answer the ââ¬Å"whyâ⬠aspect of the question and discuss the reasons why the message is important to both you and others. This is the last of the 4 prompt options and we recommend choosing the prompt you have the strongest connection to. Remember, there is no ââ¬Å"bestâ⬠prompt; regardless of the prompt you choose, ensure that you reveal something about your personality and give the admissions committee a closer look at your background Submit your essay and weââ¬â¢ll get back to you with helpful edits. This essay is only required for those applying under architecture. Like the previous prompts, this essay also has a word limit of 250 words. If youââ¬â¢ve traveled to a place with intricate and unique architecture, or you visited a site that excluded aesthetic excellence, this is the place to discuss that. Perhaps you were intrigued by the ancient architecture and designs featured in ancient Greece. Or perhaps you were fascinated by a particular home you saw while driving through Hollywood Hills due to its unique modern characteristics. Be detailed when describing the instance or location, and allow the reader to visualize the design. Your goal for this essay is to highlight the location that inspired you and explain why this was inspiring for you. Maybe you loved the detailed engravings embedded into ancient European architecture or maybe you love the intersection of minimalism and functionality. Make sure to convey the passion you have towards architecture and show a genuine interest and love for unique designs. For those of you interested in kinesiology, or the study of how the body moves, you must complete this essay. There could be several reasons why you chose this field of study but make sure to choose something that is personal to you and had a large impact in terms of exciting your interest in the subject. For instance, if you volunteered in a hospital and often worked with patients recovering from physical injuries, you could discuss watching people slowly regain mobility. You could discuss how you were amazed by the bodyââ¬â¢s ability to recover and how a person could transition from immobility to mobility. Maybe you have a more personal connection and witnessed a friend or family member experience the same recovery. If so, you could definitely include this in discussing your motivation for pursuing kinesiology. You could also discuss the science and mechanics behind kinesiology if you did not necessarily have a defining moment that influenced you to choose the field. Perhaps you are interested biomechanics behind kinesiology and were always intrigued by how the body interacts with itself. If you have played sports before, you could draw a connection between the two here and discuss how your interest in sports influenced your interest in the bodyââ¬â¢s mechanics. You want to identify a problem thatââ¬â¢s important to you and propose a solution to solve it. This doesnââ¬â¢t mean the problem has to be large, as the prompt also explicitly states ââ¬Å"small engineering project.â⬠For instance, if you live in a large household with many siblings, perhaps you want to design a robot that cleans the house, easing the daily burden on your parent. If your grandfather struggles with putting on his shoes due to a weak back, you could propose a machine that assists him with that every morning. A great way to address the prompt is to consider any medical disabilities that a friend or family member may have. However, make sure to propose something that doesnââ¬â¢t already exist. For instance, if a family member is hard of hearing, you wouldnââ¬â¢t want to design a hearing aid since this already exists. If, however, you have a proposed modification that makes an existing device better for your chosen individual, then this would be appropriate to discuss. Pay attention to the people surrounding you by identifying any daily challenges they may experience. Once you choose your project, you want to describe the design and explain how this would be beneficial to your chosen family member or friend. This prompt is essentially asking you why you want to study nursing. You want to trace your previous experiences and consider whether they impacted your decision to study health care. Perhaps an experiences volunteering at a hospital changed influenced your love for nursing, or perhaps you realized nursing comes naturally to you after caring for an ill friend or family member. If you worked or volunteered at a hospital, you could discuss a specific interaction you had with a patient. For example, maybe an elderly woman recently exited surgery and you were assigned to assist with her recovery. Perhaps the woman would often tell stories about her past experiences to you, reminding you of your own grandmother. Maybe itââ¬â¢s this deep interaction with patients that has attracted you to nursing. You want to be personal in your response; donââ¬â¢t simply state that you want to study nursing in order to help people. These answers are cliche and vague, as they donââ¬â¢t really highlight a particular experience that you had. With so many fields classified under arts and sciences, you have a variety of ways to approach this answer. If youââ¬â¢re studying biology, for example, perhaps a unique experiment in the lab opened your eyes to the intricacies of life. If you want to study math, maybe you struggled with learning a theorem and want to discuss how you overcame this challenge. Maybe Toni Morrisonââ¬â¢s Beloved introduced you to the darker side of literature that made you both uncomfortable and intrigued. You want to discuss why and how the work challenged or changed you rather than simply describing the work itself. The key here is to draw a personal connection and explain how the work impacted you by describing your personal reactions to it. For example, if you found reading Chaucerââ¬â¢s The Canterbury Tales challenging whether it be due to the language or content, you could describe the obstacles you encountered while analyzing the text. You could then conclude with discussing how working through these obstacles forced you to look at literature from a different perspective, thus allowing you to find unique symbols in the text that you otherwise would have skipped over. Remember, the purpose of these essays is to showcase your identity to the admissions officers. You want to highlight your personality and convey your passions in order to allow the reader to get a better sense of who you are. We hope this guide has allowed you to tackle UVAââ¬â¢s application with the utmost confidence. Happy writing! Want help on your University of Virginia application or essays?

Cultural concerns in healthcare Essay Example | Topics and Well Written Essays - 750 words
Cultural concerns in healthcare - Essay Example Cultural competence in nursing can be defined as the ability of a nurse to meet the requirements and wishes of all kinds of patients regardless of the color of their skin, religious conviction, or even language. In this presentation, we will focus on Asian Americans and Islam in relation to cultural concerns to healthcare. Culture plays a significant role in healthcare today. Different cultures have diverse viewpoints or ideas on the reasons behind each and every disease or medical condition. In addition, different cultures have their own ideas in regard to management and curing of particular diseases, and have their own healers or traditional doctors. Therefore, all strategies aimed at eradication and treatment of diseases within the society ought to countenance with cultural beliefs. To understand cultural concerns in healthcare, let us focus our attention on a specific cultural practice and belief relating to the Asian Americans. An assertion by Yoo, Le and Oda (2012) elucidate Asian Americans cultural beliefs on the origins of illnesses. They posit that "An individual illness may have a spiritual explanation whereby an individual was being punished for his sins or possessed by an evil spirit, an imbalance of hot and cold caused by not enough off one kind of food or the other, a weakness of the will, an imbalance of the vital energy, or a magical explanation, such as an evil eye" (p. 271). According to Dayer-Berenson (2011), Muslims require their women to cover their bodies completely except the face and hands. In healthcare therefore, this practice ought to be respected. Since some forms of medical examinations have to be done in hospital attire, the hospital staff should avail hospital attires that covers their bodies completely in accordance with their religion. However, some hospitals allow Muslim women to retain their own attires in cases where the hospital is unable to avail an

The Politics in Itself Can be a Major Force in Determining Growth and Essay
The Politics in Itself Can be a Major Force in Determining Growth and Development of a ountry - Essay Example On the other hand poor lack of political stability leads to the poor performance of the economy and may act as a significant variable in the collapse of the governmental structures and its functioning (Alesina et al, 1992, p.1). The paper centers on the discussion of the political environment with several policies as well as their implications with respect to two underdeveloped countries namely Vietnam and Bangladesh. An in depth analysis will be guiding the ways in the realization of the theme of the paper. The fundamental notion of the interdependence of politics and economic growth Theoretical underpinnings regarding the correlation of the politics and economic growth is highly based upon the uncertainty effects and that of the productive economic ideas and decisions, investments as well as that of production and labor supply. A high propensity of a change in the government is vehemently attached with the domain of uncertainty about the new policies of a new government with the ri sk adverse economic agents hesitating for adapting productive economic initiatives and finding good ventures in the abroad. Again for the foreign investments to infiltrate within the economy, the foreign political governments usually prefer economies with political stability which directs towards less uncertainty with the policies and property rights dynamics. There is presence of several literatures on the so called association. As for example, Alesina and Tabellini (1990), Tabellini and Alesina (1990), Cukierman, Edwards and Tabellini (1992), 6zler and Tabellini (1991) has developed several models where a government striving with uncertainty engages them in policies which yields sub optimal levels leading to the worsening of the economic condition of the state. These models all state share a common idea which states that outcome of the political instability generates economic inefficiencies. Within the vast domain of the stated model development, mainly within the works of Alesina and Tabellini (1989) examines the fact that effect of the political uncertainty is immensely adverse on the investment and capital injections within the economy. The probability of a governmental collapse with that of the development of a new government are highly prone towards the tax capital and productive activities signifying a substitution procedure of productive domestic investments in favor of consumption and capital flight, which in turn leads to a reduction of domestic production. There are several literatures developed on similar topic but the most relevant part in accordance with that of the elaboration in the subsequent segments has been discussed. Now the paper will plunge into the development of the hardcore mechanics which will reflect the theme of the paper with respect to Vietnam and Bangladesh. The following segment will be focusing on the case study of Vietnam and after that the case of Bangladesh will be considered (Alesina et al, 1992, pp. 3-4). Vietnam-Politic s and economic growth Background & reshuffling the power structure The country of Vietnam has gone through almost three decades of war. In the year 1945, the country declared independence from France which the French government did not recognize. As a consequence, a war broke out between Vietnam and France where France was defeated in the North Vietnam with the outbreak of a civil war. Now with the communal tensions being one of the predominant phenomenons at that time the Americans involved themselves in war with Vietnam, the

The Symbolism of Hester Prynnes Appearance in The Scarlet Letter :: Essays Papers
The Symbolism of Hester Prynnes Appearance in The Scarlet Letter Throughout The Scarlet Letter, the author Nathaniel Hawthorne uses many literal and figurative items to illustrate the significance of various characters or themes. Coupled with the tangible evidence given, the reader can make many miscellaneous assumptions of the importance of these items to directly and indirectly contribute to the issues of the novel. One cryptic item that symbolizes more than it seems to is the appearance of one of the main characters, Hester Prynne. Hester Prynne's appearance and hair signify the levels of will and determination she possesses at the moment. The first example of this implication occurs at the beginning of the novel, during and before the first scaffold scene. Hester's hair is let down, shining and "so glossy that it threw off the sunshine with a gleam." This hair compliments an elegant, beautiful woman standing tall and proud. During this time, Hester's emotions, at full integrity, mirroring her appearance. When Hester is being questioned upon the scaffold, her virtue shines through when she refuses to name the partner of her sin. In the next example, Hester's pride and stature both seem to dwindle in accordance to her appearance. Within the next seven years, Hester has gone through a change both physically and emotionally. The book describes the scarlet letter to have absorbed all the rebellious and fiery qualities of Hester, leaving a cold and lonely woman, her tenderness "crushed so deeply into her heart that it can never show itself more." At the same time, Hester started "hiding" her beautiful rich hair in a cap, therefore practically eliminating her beauty and femininity. As Hester becomes less passionate internally, she becomes less passionate externally as well. The last example takes place during Hester's talk with Arthur Dimmesdale in the forest. During their emotional conversation, Hester regains her previous composure, and tries to prove to Arthur that the past can be erased. With the literal simple gestures of pulling off her scarlet letter and taking off her cap, she figuratively obliterated all that had happened before she was forced to wear the scarlet letter. Her womanliness and pride came rushing back as her hair fell back to her shoulders, becoming as she was before the scarlet letter took over her life.

Plant Tissue Culture Essay
Plant tissue culture is a collection of techniques used to maintain or grow plant cells, tissues or organs under sterile conditions on a nutrient culture medium of known composition. Plant tissue culture is widely used to produce clones of a plant in a method known as micropropagation. Different techniques in plant tissue culture may offer certain advantages over traditional methods of propagation, including: â⬠¢The production of exact copies of plants that produce particularly good flowers, fruits, or have other desirable traits. â⬠¢To quickly produce mature plants. â⬠¢The production of multiples of plants in the absence of seeds or necessary pollinators to produce seeds. â⬠¢The regeneration of whole plants from plant cells that have been genetically modified. â⬠¢The production of plants in sterile containers that allows them to be moved with greatly reduced chances of transmitting diseases, pests, and pathogens. â⬠¢The production of plants from seeds that otherwise have very low chances of germinating and growing, i.e.: orchids and nepenthes. â⬠¢To clean particular plants of viral and other infections and to quickly multiply these plants as ââ¬Ëcleaned stockââ¬â¢ for horticulture and agriculture. Plant tissue culture relies on the fact that many plant cells have the ability to regenerate a whole plant (totipotency). Single cells, plant cells without cell walls (protoplasts), pieces of leaves, or (less commonly) roots can often be used to generate a new plant on culture media given the required nutrients and plant hormo nes. Techniques Modern plant tissue culture is performed under aseptic conditions under HEPA filtered air provided by a laminar flow cabinet. Living plant materials from the environment are naturally contaminated on their surfaces (and sometimes interiors) with microorganisms, so surface sterilization of starting material (explants) in chemical solutions (usually sodium or calcium hypochlorite or mercuric chloride) is required. Mercuric chloride is seldom used as a plant sterilant today, unless other sterilizing agents are found to be ineffective, as it is dangerous to use, and is difficult to dispose of. Explants are then usually placed on the surface of a solid culture medium, but are sometimes placed directly into a liquid medium, particularly when cell suspension cultures are desired. Solid and liquid media are generally composed of inorganic salts plus a few organic nutrients, vitamins and plant hormones. Solid media are prepared from liquid media with the addition of a gelling agent, usually p urified agar. In vitro tissue culture potato explants The composition of the medium, particularly the plant hormones and the nitrogen source (nitrate versus ammonium salts or amino acids) have profound effects on the morphology of the tissues that grow from the initial explant. For example, an excess of auxin will often result in a proliferation of roots, while an excess of cytokinin may yield shoots. A balance of both auxin and cytokinin will often produce an unorganised growth of cells, or callus, but the morphology of the outgrowth will depend on the plant species as well as the medium composition. As cultures grow, pieces are typically sliced off and transferred to new media (subcultured) to allow for growth or to alter the morphology of the culture. The skill and experience of the tissue culturist are important in judging which pieces to culture and which to discard. As shoots emerge from a culture, they may be sliced off and rooted with auxin to produce plantlets which, when mature, can be transferred to potting soil for further g rowth in the greenhouse as normal plants. [1] Choice of explant The tissue obtained from the plant to culture is called an explant. Based on work with certain model systems, particularly tobacco, it has often been claimed that a totipotent explant can be grown from any part of the plant. However, this concept has been vitiated in practice. In many species explants of various organs vary in their rates of growth and regeneration, while some do not grow at all. The choice of explant material also determines if the plantlets developed via tissue culture are haploid or diploid. Also the risk of microbial contamination is increased with inappropriate explants. Thus it is very important that an appropriate choice of explant be made prior to tissue culture. The specific differences in the regeneration potential of different organs and explants have various explanations. The significant factors include differences in the stage of the cells in the cell cycle, the availability of or ability to transport endogenous growth regulators, and the metabolic capabilities of the cells. The most commonly used tissue explants are the meristematic ends of the plants like the stem tip, auxiliary bud tip and root tip. These tissues have high rates of cell division and either concentrate or produce required growth regulating substances including auxins and cytokinins. The pathways through which whole plants are regenerated from cells and tissues or explants such as meristems broadly fall into three types: 1.The method in which explants that include a meristem (viz. the shoot tips or nodes) are grown on appropriate media supplemented with plant growth regulators to induce proliferation of multiple shoots, followed by rooting of the excised shoots to regenerate whole plants, 2.The method in which totipotency of cells is realized in the form of de novo organogenesis, either directly in the form of induction of shoot meristems on the explants or indirectly via a callus (unorganised mass of cells resulting from proliferation of cells of the explant) and plants are regenerated through induction of roots on the resultant shoots, 3.Somatic embryogenesis, in which asexual adventive embryos (comparable to zygotic embryos in their structure and development) are induced directly on explants or indirectly through a callus phase. The first method involving the meristems and induction of multiple shoots is the preferred method for the micropropagation industry since the risks of somaclonal variation (genetic variation induced in tissue culture) are minimal when compared to the other two methods. Somatic embryogenesis is a method that has the potential to be several times higher in multiplication rates and is amenable to handling in liquid culture systems like bioreac tors. Some explants, like the root tip, are hard to isolate and are contaminated with soil microflora that become problematic during the tissue culture process. Certain soil microflora can form tight associations with the root systems, or even grow within the root. Soil particles bound to roots are difficult to remove without injury to the roots that then allows microbial attack. These associated microflora will generally overgrow the tissue culture medium before there is significant growth of plant tissue. Aerial (above soil) explants are also rich in undesirable microflora. However, they are more easily removed from the explant by gentle rinsing, and the remainder usually can be killed by surface sterilization. Most of the surface microflora do not form tight associations with the plant tissue. Such associations can usually be found by visual inspection as a mosaic, de-colorization or localized necrosis on the surface of the explant. An alternative for obtaining uncontaminated explants is to take explants from seedlings which are aseptically grown from surface-sterilized seeds. The hard surface of the seed is less permeable to penetration of harsh surface sterilizing agents, such as hypochlorite, so the acceptable conditions of sterilization used for seeds can be much more stringent than for vegetative tissues. Tissue cultured plants are clones. If the original mother plant used to produce the first explants is susceptible to a pathogen or environmental condition, the entire crop would be susceptible to the same problem. Conversely, any positive traits would remain within the line also. Applications Plant tissue culture is used widely in plant science; it also has a number of commercial applications. Applications include: â⬠¢Micropropagation is widely used in forestry and in floriculture. Micropropagation can also be used to conserve rare or endangered plant species.[2] â⬠¢A plant breeder may use tissue culture to screen cells rather than plants for advantageous characters, e.g. herbicide resistance/tolerance. â⬠¢Large-scale growth of plant cells in liquid culture in bioreactors for production of valuable compounds, like plant-derived secondary metabolites and recombinant proteins used as biopharmaceuticals.[3] â⬠¢To cross distantly related species by protoplast fusion and regeneration of the novel hybrid. â⬠¢To cross-pollinate distantly related species and then tissue culture the resulting embryo which would otherwise normally die (Embryo Rescue). â⬠¢For production of doubled monoploid (dihaploid) plants from haploid cultures to achieve homozygous lines more rapidly in breeding programmes, usually by treatment with colchicine which causes doubling of the chromosome number. â⬠¢As a tissue for transformation, followed by either short-term testing of genetic constructs or regeneration of transgenic plants. â⬠¢Certain techniques such as meristem tip culture can be used to produce clean plant material from virused stock, such as potatoes and many species of soft fruit. â⬠¢Micropropagation using meristem and shoot culture to produce large numbers of identical individuals. â⬠¢Production of identical sterile hybrid species can be obtained. Laboratories Although some growers and nurseries have their own labs for propagating plants by the technique of tissue culture, a number of independent laboratories provide custom propagation services. The Plant Tissue Culture Information Exchange lists many commercial tissue culture labs. Since plant tissue culture is a very labour intensive process, this would be an important factor in determining which plants would be commercially viable to propagate in a laboratory.

Resource and Time Management Resources and time management play an important role in making a project success. Organizations rely on resources to carry out the project tasks. Time management is very critical in the project completion. The resources need to be able to follow the process and make sure to finish the tasks on time. Without the correct team/resources set up, any procedure and plan have the capability of totally falling apart. In my opinion, project manager and entire team needs to work in a collaborative style, that is really important to ensure the success of a project and to finish the project on time. According to Kerzner (2001), project success was clearly explained as the completion of a project within the specified budget, time, performance. This de?à ¬nition of project success has been modified to incorporate completion within the mentioned time period, at the possible execution or specification level. Donââ¬â¢t waste time! Our writers will create an original "Resources And Time Management" essay for you Create order A project can be viewed as effective by meeting the execution measures of cost, time and technical performance, but also ensuring and safeguarding that the project is acknowledged and accepted by the client (Kerzner 1998). I would like to concentrate more on time, resource performance and of course customer satisfaction. Success will be determined by the level of execution accomplished. To decide whether these factors are actually useful and success will be depending on their impact on project execution. Belassi and Tukel (1996) grouped critical success factors into four zones: external environment, team, organization and the project. The identi?à ¬cation of critical factors would prompt the better assessment of projects. Pinto and Slevin (1987) found ten critical success factors, including project mission, top administration support, project schedule/plan, customer consultation, personnel, technical tasks, client acceptance, monitoring and feedback, communication and investigating. This exploration just identified the critical success factors, yet did not quantify the quality of their association with project performance. Cooke-Davies (2002) recommended a range of critical success factors related to performance, including project team and management competencies relevant to huge, complex projects, but also to projects in general. Project management incorporates productively overseeing individuals and partnerships viably. The decision power should be given to sponsor and the sponsor must work with project manager and they need to be in a decent understanding about the wants of a project. The project manager needs to be clear on making the requirements clear with the management. And the leadership should really give the decision power to the sponsor who will then take care on getting requirements done quickly. We need to be clear and transparent with the stakeholders that help them understand the performance. Communicate with upper management and come to an understanding on the decisions and have their support financially. The sponsor needs to be available and help in making decisions and influencing the stakeholders and management. Team work needs communication, coordination ability to do exploration on the tasks. Make sure involve right person on right time. Include the stakeholders in meetings in order to better identify if any issues at that moment. As work demands increase, managers need to manage time and work projects effectively. Knowing how you invest your time is the initial step to enhance and improve efficiency and time management. Managers ought to distinguish performance time and wasteful time utilize. MANAGING TIME Every team member should manage their time effectively and work to achieve project success, some of the basic things to consider: Try to work on the critical stuff on priority and schedule the less important or priority tasks to later. Also, make sure you dont switch tasks, that leads to time loss understanding both. Raffoni (2006) reports that switching between tasks could diminish effectiveness by 20% to 40%. Since email interferences can distract from work and take time to read and reply to e-mails. Enhancing time and project management incudes creating work time without interferences. When working on a project, do not end up interrupted by unnecessary talk from colleagues. The tasks need to show the manageable steps of the project. Also, they ought to be divided into subtasks which take less time to complete. It is ok to say no to colleagues when they try to give you more work or ask questions when you do not have time. Organization is another key factor in project and time management for managers. Workplace organization is critical to work effectively. Time spent searching for files, folders, or projects is considered waste. Keep moving towards technology which gives us the features to do our work in less time. Because many files are now electronic, retain only essential hard copy documents. Often update and back up the files that you complete. Eliminate duplicates and rough drafts of completed work. This greatly reduces manual work and saves time. All the team members ought to be communicating within themselves often and offer the ideas. Following agile really helps in determining the tasks and also the fixes if something goes wrong. Agile is flexible and the team members and project manager should follow the principles of agile methodology. Utilize the tools available to you to reduce work load and make sure everything is done on time. Would like to discuss on more on agile methodologies which the team uses, it involves communication like handling stand-up calls and the progress made everyday by team members. Having code reviews by the team and automate the tasks to test. Follow agile principles and methodologies in project, more focus to individuals than to process and tools. Just make sure to provide adequate documentation. Respond to changes quickly. Give more importance to customer feedback than the requirements defined. Of course we need to follow requirements and develop the tasks but when comes to customer satisfaction and needs, we need to give preference to the client. Keeping to the timetable in which the design and requirements are created. And to how well the team can convey the outcomes characterized in scope. We often hear organizations have been faced with problems in delivering, so the project manager should make sure we dont go beyond scope and timelines. Then the team can work towards increasing speed and in post-execution adjustments accordingly.
