The process of designing a research study involves many interrelated decisions. The most significant decision is the choice of research approach, because it determines how the information will be obtained. To design something also means to ensure that the pieces fit together. The achievement of this fit among objective, research approach, and research tactics is inherently an iterative process in which earlier decisions are constantly reconsidered in light of subsequent decisions.

Chapter 3 – Research Design V.E.S College of Arts, Science & Commerce 1.2 Problem Definition A problem exists when the decision-maker faces uncertainty regarding which action to adopt in the situation. If only one action is available (or none at all) or if there is certainty about the outcomes of the alternatives, there really is no problem. Defining a problem is a situation where: 1) The decision-maker has not yet determined how to exploit an opportunity or 2) There are difficulties that are currently faced or are anticipated. For instance the marketing manager may state that sales of a product have fallen by 25% because its price is too high & hence may ask the researcher to throw more light on “what is a more effective price”? Actually the decline in sales may be due to any other factor or factor like poor product quality, competitor’s action, poor salesmanship etc. The research dealing solely with the price may be able to solve the problem correctly. The existence of a disorder or a problem is the reason why the research is needed. Once the problem is identified/disorder is located, the researcher may set the projects objectives. The project’s objectives are the specific purpose or goal of the research, since the objective flow from the disorder must precede the selection of the objectives. 1.3 Components of Problem A problem consists of a set of specific components: a) The decision maker and his or her objectives ; b) The environment or context of the problem; c) Alternative courses of action; d) A set of consequences that relate to courses of action and the occurrences of events not under the control of the decision maker and; e) A state of doubt
