Eficient and well-planned activities always see success. Therefore, one need to efficiently plan a research activity, execute it meticulously, and publish it for outside world.

In a house-building task, the first blueprint needs to be finalized and one has to visualize all minute details such as position and size of rooms, doors, windows, balconies, and so on. Estimation of all required material should be finalized along with quality and quantity. Improper planning and estimates may not able to produce the expected dream house. Similarly, researchers should follow research process to get optimized research outcomes. General steps in the research process are shown in Figure 1.3 and selection of research problem is shown in Figure 1.4. Identification or selection of research domain is a very initial stage in the process of research, followed by formulating a tentative research problem. Selection of research guide can be done at initially or at any intermediate stages of research problem selection. If the problem is well-defined with research objectives initial phases can be combined and researcher can directly start with literature survey. Literature survey can be revisited number of times during research process. Researcher can switch from intermediate state to literature survey and back to the same state.
