At the beginning of any new client engagement, we were expected to develop a “Day One Hypothesis.” Based on the high-level facts that we had learned within the first 24 hours of the project, we were forced to develop an early hypothesis of what the solution to the client’s problem was.How you develop your hypothesis is a combination of good problem solving skills, pattern matching, and intuition.
