How to read these examples
The scenarios explain the reasoning behind an investigation plan, including what records might be useful, how competing accounts could be tested and what a report would need to disclose. They are educational examples, rather than evidence of completed client projects.
What changes from matter to matter
Authority to collect, access, participant cooperation, source quality and deadlines affect the actual work. Read the limitations alongside the method. A properly qualified finding is more useful than a promised outcome that the evidence cannot support.
