Just the other day I was helping a student refine their problem statement. They had done a good job, but had assumed their reader had a certain background knowledge that they were unlikely to have. The student needed to take a step back in providing background so that the reader could see why the problem was important. It was easy to see once you started thinking “so what?”, “why?” and “who cares?” as you read the student’s problem statement.
The Purdue University Online Learning Lab has a bit more about problem statements and thinking about what your reader already knows at this link here. https://owl.english.purdue.edu/owl/resource/957/01/
