Research methods

The goal of the research process is to produce new knowledge, which takes three main forms (although, as previously discussed, the boundaries between them may be fuzzy):
• Exploratory research, which structures and identifies new problems
• Constructive research, which develops solutions to a problem
• Empirical research, which tests the feasibility of a solution using empirical evidence

Research can also fall into two distinct types:
• Primary research
• Secondary research
Research is often conducted using the hourglass model.[1] The hourglass model starts with a broad spectrum for research, focusing in on the required information through the methodology of the project (like the neck of the hourglass), then expands the research in the form of discussion and results.
