State the objective in one sentence
If the objective needs a paragraph, it is probably several objectives. Pick the one that matters most for this piece of work and let the others wait.
Describe the audience
Include who they are, what they are trying to achieve, and what would make them hesitate. Two or three sentences is enough if they are specific.
List the deliverables
Name each item that will be handed over. “A content plan” is ambiguous. “Content themes, twenty topic ideas and a four-week calendar” is not.
Agree the revision allowance
Say how many rounds of feedback are included and what counts as a revision rather than new work. This protects both sides.
Set the schedule and the inputs
Note when the work is expected and what you need to supply for it to start. Most delays in small projects are caused by missing information, not missing effort.
Where to take this next
If you would like this applied to your own business rather than read in the abstract, the marketing packages cover reviews, campaign planning, content plans and full strategies as fixed-scope pieces of work.
