Categorise your last five years of engagements
You cannot productise what you have not named. A simple categorisation of every engagement since 2021 shows the three or four problems you solve repeatedly, who buys them and what they paid. That list is your product catalogue in waiting.
This week: export every engagement from the last four to five years into a sheet: client, problem, approach, value. Tag each with a problem type. Count the tags. The top three are your first products.
