Demand management
Demand management works closely with and supports capacity management in several ways:
• By helping to understand patterns of business activity and user profiles,
demand management helps capacity management more accurately predict and plan for the consumption of resources for new users.
• By finding ways to smooth out peak loads, demand management helps
capacity management make the most cost-effective use of existing resources and helps to defer the purchase of new resources.
• During times of peak load, demand management can dynamically throttle usage to maintain service levels, for example by restricting the number of concurrent users of an online system to protect response times.
