The factors or elements that determine how much the system can accomplish.


Types of Constraints:

Capacity Constraint – a resource which cannot provide timely capacity the systems demands for it.

Market Constraint – the amount of customers’ orders is not sufficient to sustain the required growth of the system.

Time Constraint – The response time of the system to the requirement of the market is too long to the extent that it jeopardizes the system’s ability to meet its current commitment to its customers as well as the ability of winning new business.
