A client calls with a list of unexpected changes to a project Thursday afternoon, with the big deadline coming up Monday. He concedes that this was not a part of the plan but asks that you work over the weekend to meet it. Your initial reaction is most likely to:
Ask them for clear, achievable milestones for each of the days leading up to the deadline to ensure you remain on track, given the new tight timeline
Feel reassured by the fact that the way he asked shows he appreciates that this is a major sacrifice
Recognize this just happens occasionally and is sometimes necessary to get the job done right
Push back on certain changes that you feel compromise the integrity of your work
Remind him that this work is out of scope and will cost him a lot more
