Slow Work Needs Time

Some work is not meant to be done quickly and not meant to be done by a specific date either.

It is not unreasonable to expect output and results in time to be able to progress, but slow work needs time.

Pin a deadline on or timebox an activity and be prepared to make trade offs.

Trade offs could mean less than ideal.
Perhaps “less than ideal” is what’s needed for the work to be done.

Also…

'When will it be done' is an unanswerable question. However, 'what’s the probability of satisfying our strategic goals by this date at this cost' is both answerable and a reasonable ask as long as specific details of 'how' aren’t fixed.
