Avoid digressions and pedantic detail. This isn’t a thesis assessment, stakeholders will trust the writer with some details if they are show they are being honest about addressing all sides of the problem.
And, on the mysterious ppendices:
Use Appendices: if it isn’t centrally important to the argument but might come up in discussion, move it to the Appendices. Now it is easy to abuse appendices and end up with a 6 page document which needs more than 6 pages to be understood. As an example, the following content is fine: Long Tables, Detailed Graphs, FAQs on exceptional cases, Long lists of specific examples. Importantly, there should be no narrative text in the Appendices.
Other advice and an overview of structure.
