Case notes, not case studies: the problem, what we did, and the number that moved. Client names are withheld throughout. Every system here was built, run or measured by us, and any of them can be walked through on the call.
Every case note above uses the same rule as every fortnightly review: a number from before, the same number from after, and the unit. Where the record only has the outcome in words, the number is marked to be added rather than invented.
Bring the problem, not a brief. If it is outside what we do well, we will say which of our contacts to call instead.
