Your relationship
Making something usable and refining its finish may complement each other. Different standards for “enough” can bring a wish to hurry alongside a wish to revise.
As romantic partners
Even before everything is perfect, saying what makes you happy now can help a person who shows love through action and one who notices details receive different forms of affection.
As friends
Discussing the purpose first and preferences afterward can keep practicality and sensitivity from competing on one scale.
As colleagues
Agreeing first on the finish standard and deadline, then choosing the details to care for, can share execution and refinement within the same process.
