Ongoing work
In some cases, ongoing work may be useful following an engagement.
This is not standard, and not always necessary.
It depends on:
the nature of the work
what is uncovered during the engagement
whether there is value in continuing
Where it does continue, the focus remains the same:
working with what is actually happening
maintaining clarity as changes are made
addressing new or shifting points of difficulty
Ongoing work is limited and agreed on a case-by-case basis.
