You will miss deliverables.
They will slip.
Something will crop up that will make it impossible for you to hit.
The questions that matter more are;
- Did you give people notice weeks or hours before?
- Do you have a backup plan?
- Are you short on resources to accomplish the goal?
- What changed that impacted things?
Often we aren’t concerned about the missed deliverable, but why it happened, when did we think it was going to happen, and what’s the plan for getting back on track.
That’s what builds leadership in software delivery.
