Figure 1The sales capacity planning architecture

Capacity Parameter	Operational Mechanism	Standard Enterprise Benchmark	Governance Defect if Omitted
Ramp Factor ($r_i(t)$)	Productivity discount during onboarding	3 to 9 months to full quota	New hires expected to produce on Day 1
Attrition Buffer ($a_i(t)$)	Regretted and un-regretted rep turnover	15% to 25% annual sales turnover	Pipeline evaporates when vacated territories stall
Attainment Realism ($\alpha$)	Historical percentage of quota achieved	70% to 80% blended team attainment	Plan assumes 100% of reps hit 100% of quota
Selling Time Constraint	Actual hours spent customer-facing	32% to 38% of total weekly working hours	Reps overwhelmed by administrative data entry
Support Ratios	AE-to-SDR and AE-to-SE staffing	1:1 SDR ratio; 2:1 Solutions Engineer ratio	Account executives starved of technical support
