As it is not possible to start constructing a building without proper design outlay, so is the case for research materials design. Before initiating the research project, it needs to be comprehensively designed and prepared in the way it requires structuring and accomplishing. It starts with a question or problem, which needs to be addressed and approached. Therefore, it's nothing but a detailed preparation of data collection and analysis at economy of expenditure. Research materials design could be categorized as sampling design, observational design, statistical design, and operational design.
