Roger L McCarty Develop Hypotheses A hypothesis is a solution statement presumed to be true until proven otherwise. Develop hypotheses to truncate analysis and to begin to zero in on solutions. Discard or change a hypothesis if further research disproves it. The second step in case analysis is to develop hypotheses. Perhaps the most critical technique in problem-solving is to develop hypotheses about the solution immediately after the problem is defined.
Roger L McCarty Develop Hypotheses Quick and Dirty Test (QDT): What are the key issues that support or refute the hypothesis? What assumptions need to be true in order for the hypothesis to be true?

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
