The most useful diligence question is often the simplest

In diligence we spend a lot of time investigating. Documents, systems, reports, all to understand how things really work. Often the most useful insight comes from something much simpler. Just asking.

Questions like: What feels harder than it should be here? What breaks first if the business doubles, trebles or grows tenfold? What work do people quietly work around? What would you build differently if you were starting again today?

These questions are not designed to trip anyone up, but they often reveal more than hours of documentation, which tends to paint a slightly rosier version of the truth. Documentation is usually written by the people who designed the system, and it describes the intent. The people running it day to day know the reality.

The most useful answers are rarely the polished ones. They tend to come with a small pause, a glance sideways, and then a more honest sentence about what actually happens at month-end, or which process the team never quite trusts.

The interesting thing is not always how the systems are set up or presented. It is what the people running them already know. Sometimes the fastest way to find that out is simply to ask.
