How is the term `research design' to be used in this book? An analogy
might help. When constructing a building there is no point ordering
materials or setting critical dates for completion of project stages until we
know what sort of building is being constructed. The ®rst decision is
whether we need a high rise of®ce building, a factory for manufacturing
machinery, a school, a residential home or an apartment block. Until this
is done we cannot sketch a plan, obtain permits, work out a work
schedule or order materials.

Research design carries an important influence on the reliability of the results attained. It therefore provides a solid base for the whole research. It is needed due to the fact that it allows for the smooth working of the many research operations. This makes the research as effective as possible by providing maximum information with minimum spending of effort, money and time. For building of a car, we must have a suitable blueprint made by an expert designer. In a similar fashion, we require a suitable design or plan just before data collection and analysis of the research project. Planning of design must be carried out cautiously as even a small mistake might mess up the purpose of the entire project. The design helps the investigator to organize his ideas, which helps to recognize and fix his faults, if any. In a good research design, all the components go together with each other in a coherent way. The theoretical and conceptual framework must with the research goals and purposes. In the same way, the data gathering method must fit with the research purposes, conceptual and theoretical framework and method of data analysis
