Tie the task back to the business value.
Tie the task to the project value.
Tie the task to the stakeholder’s value.
If you don’t tie the task to where it adds value then why do the task?
Sometimes the stakeholder you’re serving is you.
Sometimes the value you add to the project is isn’t to the project, but those who are doing it with you.
Not every task improves the business.
But every task should help some part improve.
