تقدير المدة الزمنية اللازمة للعمل في التطوير هو مهارة شائعة وصعبة وأساسية. التقديرات معروفة بأنها صعبة جداً (المطورون يميلون إلى التقليل من الوقت المطلوب)، لكن تحسينها والتواصل بشأنها بشكل فعّال مهم للتخطيط والثقة.
لماذا التقدير صعب
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.
تحسين التقديرات
✓ 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)
