Strengths and limitations - Better Thesis
Usually, the sample being investigated is quite small, especially when compared with probability sampling techniques. Unlike the various sampling techniques that can be used under probability sampling e. This is the general intent of research that is guided by a quantitative research design. The main goal of purposive sampling is to focus on particular characteristics of a population that are of interest, which will best enable you essay on smoking problem solution answer your research questions.
The sample being studied is not representative of the population, but for researchers pursuing qualitative or mixed methods research designsthis is not considered to be a weakness. Rather, it is a choice, the purpose of which varies depending on the type of purposing sampling technique that is used. For example, in homogeneous samplingunits are selected based on their having similar characteristics because such characteristics are of particular interested to the researcher.
By contrast, critical case sampling is frequently used in exploratoryqualitative research in order to assess whether the phenomenon of interest even exists amongst other reasons. During the course of a qualitative or mixed methods research designmore than one type of purposive sampling technique may be used.
For example, critical case sampling advantages of case study dissertation be used to investigate whether a phenomenon is worth investigating further, before adopting a maximum variation sampling technique is used to develop a wider picture of the phenomenon. We explain the different goals of these types of purposive sampling technique in the next section.
There are a wide range of purposive sampling techniques that you can use see Patton,; Kuzel,for a complete list. Each of these types of purposive sampling technique is discussed in turn:. Maximum variation sampling, also known as heterogeneous samplingis a purposive sampling technique used to capture a wide range of perspectives relating to the thing that you are interested in studying; that is, maximum variation sampling is a search for variation in perspectives, ranging from those conditions that are view to be typical advantages of case study dissertation to those that are more extreme in nature.
By conditionswe mean the units i. These units may exhibit a wide range of attributes, behaviours, experiences, incidents, qualities, situations, and so forth. The basic principle behind maximum variation sampling is to gain greater insights into a phenomenon by looking at it from all angles.
This can often help the researcher to identify common themes that are evident across the sample. Homogeneous sampling is a purposive sampling technique that aims to achieve a homogeneous sample; that is, a sample whose units e.
In this respect, homogeneous sampling is the opposite of maximum variation sampling.
What are the benefits and drawbacks of case study research? - Social Theory Applied
A homogeneous sample is often chosen when the research question that is being address is specific daily homework chart the characteristics of the particular group of interest, which is subsequently examined in detail.
The word typical does not mean that the dissertation case study analysis is representative in the sense of probability sampling i. Rather, the word typical means that the researcher has the ability to compare the findings from a study using typical case sampling with other similar samples i.
Therefore, with typical case sampling, you cannot use the sample to make generalisations to a population, but the sample could be illustrative of other similar samples. Whilst typical case sampling can be used exclusively, it may also follow another type of purposive sampling technique, such as maximum variation sampling, which can help to act as an exploratory sampling strategy to identify the typical cases that are subsequently selected.
Extreme or deviant case sampling is a type of purposive sampling that is used to focus on cases that are special or unusualtypically in the sense that the cases highlight notable outcomesfailures or successes. Toggle navigation Carolina Digital Repository. Help Contact Us Login.

They do not attempt to eliminate what cannot be discounted. They do not attempt to simplify what cannot be simplified. Thus, it is precisely because case study includes paradoxes and acknowledges that there are no simple answers, that it can and should qualify as the gold standard" p. In an interesting discussion of the value of case study research, Flyvbjerg sets up five "misunderstandings" about case study research, which he then dismantles, substituting a more accurate statement about the issue underlying each misunderstanding.
These misunderstandings and their restatements are displayed in Table 3. The second misunderstanding, for example, "that one cannot generalize on the basis of a single case is usually considered to be devastating to the case study as a scientific method" p. However, citing single cases, experiments, and experiences of Galileo, Newton, Einstein, Bohr, Darwin, Marx, and Freud, Flyvbjerg makes the point that both human and natural sciences can be advanced by a single case. He also argues that formal generalizations based on large samples are overrated in their contribution to scientific progress for a discussion comparing sampling, representativeness, and generalizability in both quantitative and qualitative research, see Gobo, TABLE 3.

How you report your findings depends on the type of research you are doing. Some case studies are structured like a standard scientific paper or thesis, with separate sections or chapters for the methodsresults and discussion.
Others are written in a more narrative style, aiming to explore the case from various angles and analyze its meanings and implications for example, by using textual analysis or discourse analysis. In all cases, though, make sure to give contextual details about the case, connect it back to the literature and theory, and discuss how it fits into wider patterns or debates. Iam in love with the Case study design. I use it frequently but the new knowledge McCombes has brought out are simple and easy to understand.
This is great and help I have identified a number of research areas, and what I did was to organize University debates around the topics so as to understand the theories further.

What I wanted to investigate with my study, was how big of a problem this is in practice. One the one hand, I had seen some instances of inconsistent clones that suspiciously looked like bugs. On the other hand, I had no idea how frequently this occurred, and if this really was problematic in practice.
My study goal was to quantify this by analyzing clones and their inconsistencies in real systems. The rationale of the first research question was to understand if inconsistent changes to clones happen at all, and how often. If they are very rare, they probably do not deserve further investigation which is performed by the later research questions in the paper. This section outlines the study objects e.
Why and maybe how those objects were chosen. This is relevant, since choice can influence study result validity. For the example, a large number of study objects and ideally their random selection from a large pool of potential study objectswould increase the generalizability of the study results.
Strengths and Limitations of Case Studies
I thus had to rely on our industry contacts to get hold of these developers. This limited my choices and thus potentially affects generalizability of the results which is mentioned in the threats to validity section. A frequent mistake is to not mention why those objects were chosen and what the consequences of the choice are.
As a reader, this makes me wonder if the selection was manipulated to better produce the answers the author was looking for.
If a study involves data from industry, the study object names are often anonymized e. For the authors, however, it makes it much easier to get clearance to publish these results.
This section describes how the study, using the information from the study objects, attempts to answer the research questions. Unilever was very good at that time even if the financial aspect was taken into consideration it could experiment with various aspects of its store cause had the financial backup which was required at that time to help it implement various ideas and deal with the market pressures, for any company to improve its sales marketing always plays a very important role this was probably there biggest strength as the marketing strategy applied by them managed to grab peoples attention as they easy to be connected to and much more simplistic and realistic.
Unilever did manage all its clients very well considering that during a phase when they where cutting on the brands it would have been a risk to out anything at that time but it was very well dissertation case study analysis by the company.

Mainly the fact that unilever was now looking to make the higher range or the brands which where more famous as there core brands which made it much easier for them to advertise considering that it is much easier to promote a very well known and a trusted brand rather than a normal or new brand to increase the sales.
The organization was probably one field in which the company was lacking because it was felt that at the top of the company as there were too many people making decisions and these decisions had to be put forward and this delayed the process of improvement for the company.
Opportunities, during this phase of development and renewing it content and upgrading of the stock it turned out to be very fruitful as it provided many working opportunities for people it was at that time that many people where starting to get full time work, during this phase a lot of acquisition also took place with the major brands which resulted in some alterations in plans to that which were planned. SlimFast which is a private company is another acquisition of Unilever after implementing path to growth strategy in the company bargained an agreement to purchase slimfast diet foods.
It had strong sales and network and has dissertation based case studies special space in every super market and drugstores these products were made from natural ingredients and added vitamins and minerals to provide good nutritional profile. Unilever has concentrated more on this Slimfast since the company was growing fast and attracted the customers to buy more of it for healthier and long living life.
Management of Unilever utilized the opportunity to globalize the product in other countries like Europe, Australia due to increase in the percent of obese. According to the world health organization percent of the obese was increasing gradually. Their sales slogan was Vermont finest All Natural Ice cream. They never use any artificial flavors thought the cost is little more it is worth the price.
According to the time magazine Vermont makes the best ice cream in the world with 29 flavors in pint cartons and 45 flavors in bulk cartons. There products were distributed throughout the world. Bestfoods was a global company across the world almost in 60 countries which was busy in manufacturing and marketing the food products.
Bestfoods profits are almost from outside of the United States that is almost 60 percent of its profits. It is one of the best managed food companies among United States who has much number of employees working with in their company in which half of them were at non US locations.
The company increased payments for 14 successive years has its revenues grow by7. Then the company introduced a strategy with four core elements. Products which are new in the market are needed to be globalized that is the products which are less popular among dissertation case study analysis consumers, are needed to be advertised and market those products to increase its sales and profits of those products. With the greateramount of research you can come up with your own solutions and hypothesis.
You will be better equipped to present a problem statement and problem identification. I can assure you that following these three steps will surely make yourcase studyofdissertation flawless in the eyes of the dissertation committee. There are many purposes of the case study method which is to explore new areas and issues where there is little data available or to explain a complex phenomenon.
Case studies usually target a particular company and qualitative and detailed analysis is made on the same. Literature Review The literature review for a case study differs slightly to others papers in that it is focused on providing background information and enabling historical interpretation of the subject in relation to the research problem the case is intended to address.
Method This is the section where you explain why you selected a particular subject of analysis to study and the strategy you used to identify and decide that your case was appropriate in addressing the problem. Discussion The main elements of this section are similar to many other papers but centered on interpreting and drawing conclusions about the key findings from your case study.
Conclusion As with all other papers, you should summarize your conclusion in clear, simple language; provide emphasis on how the math answers for algebra 1 from your case study differs from or supports previous research and why.
