Ocenjevanje kako dolgo bo trajalo razvojno delo je pogosta, zahtevna in pomembna veščina. Ocene so notorično težavne (razvijalci imajo tendencijo podcenjevanja), vendar je njihovo izboljšanje in dobra komunikacija ključna za načrtovanje in zaupanje.
Zakaj je ocenjevanje težavno
Development estimation is notoriously inaccurate:
→ UNKNOWNS → unexpected complexity, bugs, dependencies, edge cases emerge
→ OPTIMISM BIAS → developers tend to UNDERESTIMATE (imagine the happy path, forget
testing, integration, reviews, meetings, the unexpected)
→ complexity is hard to assess upfront; requirements change
→ estimates are predictions under uncertainty, not promises.
Izboljšanje ocen
✓ BREAK DOWN work → estimate smaller pieces (more accurate than one big guess); sum them
✓ Account for EVERYTHING → not just coding: testing, code review, integration, debugging,
meetings, unforeseen issues
✓ Use PAST EXPERIENCE → how long did similar work actually take? (reference real data)
✓ Add BUFFER for uncertainty → things take longer than the happy-path estimate
✓ Consider ranges or confidence ("3-5 days" vs a false-precise "4 days")
✓ Re-estimate as you learn more (estimates improve with information)
