Thank you MoJ colleagues, I much prefer "exploration" to "pre-discovery"

In the early iterations of the service manual, there was a line something like "there are a few things that you'll want to do pre-discovery". Before you knew it, departments had invented a whole new phase. Always made me uncomfortable
In the years since I've seen organisations that do the "few things you need to do pre-discovery" really well, and others that seem to make heavy weather of it
Use "exploration" to quickly frame and fund discovery right, not to impose stakeholder-anxiety-driven limits on the discovery team
