Sprint Capacity Calculation

Definitions (variables)

• H = productive hours per person per day (= 5)
• P_d = planning days (= 2)
• D_d = development days (= 10)
• B = bug-fix days (min 2, max 5)
• T_d = testing days (= 10)
• R_d = release prep days (= 3)
• S_p = people in planning (= 2)
• N_d = number of developers (= 5)
• N_t = number of testers (= 2)
• N_r = people for release/docs (= 1)

Formulas

PlanningHours = Pd × H × Sp
DevHours     = (Dd + B) × H × Nd
TestingHours = Td × H × Nt
ReleaseHours = Rd × H × Nr
TotalHours   = PlanningHours + DevHours + TestingHours + ReleaseHours
    

Numeric Iterations

Common intermediate values:
H = 5, N_d = 5, N_t = 2, S_p = 2, N_r = 1

1. PlanningHours
   2 × 5 × 2 = 20 hours
2. TestingHours
   10 × 5 × 2 = 100 hours
3. ReleaseHours
   3 × 5 × 1 = 15 hours

Case A — Minimum bug-fix (B = 2)
DevHours = (10 + 2) × 5 × 5 = 12 × 25 = 300 hours
TotalHours = 20 + 300 + 100 + 15 = 435 hours

Case B — Maximum bug-fix (B = 5)
DevHours = (10 + 5) × 5 × 5 = 15 × 25 = 375 hours
TotalHours = 20 + 375 + 100 + 15 = 510 hours

Quick Checks

• Dev team total capacity over 15 working days:
  5 × 5 × 15 = 375 hours
• Tester capacity:
  2 × 5 × 15 = 150 hours → Utilization = 100 / 150 = 66.7%
