Process and outcome
Trust your process.
If you've been deliberate from the onset about the process. If you've questioned all assumptions, taken useful feedback, and built something sustainable...
If you have done the work so well not one more unit of work will make it better...
If you agree with your team on what great work means and have designed your internal systems with this in mind...
Then do nothing more than revisit your process.
It's counter-intuitive not to change anything else.
It is almost irresponsible not to fixate on the outcomes if we measure progress by clearly defined outcomes.
But if nature taught us well, we'd remember that when we get our processes right, and the conditions we have no control over are also right, the outcome will align with what we want.
Until then, focus on the part of the process you have control over.
