Written for a colleague sweating work left undone.
The scope of the project is never more than what you can do in the time available.
If you deliver a perfect document free of typos, you have prioritized the use of your time incorrectly.
The scope of a project is equal to what you can do in the time the client paid for. You offered them a more comprehensive project; the client chose not to buy that project.
Part of the profession is knowing which problems aren't worth taking the time it would take to fix them.
The scope of the project is not what the client needs, it's what the client bought. You already pitched them what they need.
Things will go wrong whatever you do. Skill is choosing which problems are best to risk.
The client counts on your sense of professionalism to get you to do more work than they paid for. Don't fall in love with the john.
Always tell the client the truth. When they don't want you to tell them the truth, remind them that telling them the truth they don't want to hear is what they pay you to do.
That includes telling the truth about what they chose to buy from you.
The scope of the project is equal to the best you can do in the time you agreed to.
