- Long-winded sections with historical backgrounds
- A detailed description of the process your team took
- All the dead ends you hit and excluded from the analysis
- Vast analysis that proofs a point that everyone already agrees on
- Market analysis for the sake of market analysis, without supporting a point you want to make
- Explanations of management theory and frameworks you used, extensive parallels with other industries
- Elaborate competitor profiles
- Frame the options that you see
- Provide a summary why you think you need option C
- Quickly mention the evidence that everyone agrees on
- Boil things down to the decision about the more controversial parts of your argument
- Provide your logic, and provide deep fact-based analysis that support the points you are making.
