The Estimation Death Spiral
Missed estimates erode trust. Eroded trust makes estimates worse. Repeat.
“They said six weeks. It always means twelve.”
“We don't even bother with the dates anymore.”
“I gave an honest estimate and got punished for it being too high.”
What it looks like
Technology consistently misses delivery commitments. Business partners stop trusting estimates. They pad timelines. Technology starts padding too. Nobody has confidence in any timeline. Planning becomes fiction.
Why it happens
The spiral starts with a reality: software estimation is hard. But the spiral isn't about accuracy — it's about what happens when estimates are wrong.
In healthy organizations, missed estimates lead to learning. In unhealthy organizations, they lead to blame. Blame produces defensive estimation — pad everything, promise less.
The spiral accelerates when business partners respond to padded estimates by demanding tighter ones, or by going around technology entirely.
What it causes
Total collapse of delivery confidence. Both sides protecting themselves rather than collaborating. Product and business making plans that don't include technology's actual capacity.
How TRUST addresses it
Phase 2 surfaces the trust gap from the business perspective. Phase 3 reveals how estimation pressure affects leadership dynamics. Phase 4's DORA metrics provide objective delivery data. The roadmap includes both technical improvements (smaller batches, continuous delivery) and relationship repairs (transparent tracking, regular recalibration).
