Planning and Managing Resources in the Service Value System
What the exam asks
This domain tests capacity and performance, availability, workforce and talent, and the sourcing and budgeting decisions behind them. You must distinguish these practices and link them to demand and cost.
Core rules
- Capacity and performance management ensures services meet agreed performance targets cost-effectively by balancing demand against supply, using patterns such as seasonal peaks and growth.
- Availability management meets agreed availability commitments through resilient design, redundancy and component availability. Availability is not the same as reliability or maintainability.
- Workforce and talent management ensures the right competencies, capacity and engagement: roles, skills matrices, T-shaped people and succession planning.
- Resource planning forecasts demand, identifies gaps and decides whether to build, buy or partner, then budgets accordingly.
- Sourcing options include insourcing, outsourcing, multi-sourcing and SIAM; retain the capability you need to manage suppliers and outcomes.
- Demand management influences and shapes demand where capacity cannot flex.
Worked example
A retailer expects ten times normal traffic on Black Friday. Reasoning: capacity planning uses historical demand plus forecast, then adds headroom; performance testing validates the model; elastic cloud capacity may be chosen because cost follows demand rather than funding permanent hardware. Availability is addressed with redundancy in the checkout path, not simply by adding servers.
Traps
- Confusing capacity (amount) with performance (speed and responsiveness).
- Assuming availability means every component is up; it means the agreed service level is met.
- Planning resources without linking to demand forecasts, risk or budget.
