By explicitly identifying performance metrics and resource constraints, a system designer ensures that the design space is well defined, the solution is feasible, and the design is efficient.
She can then trade unconstrained resources for constrained ones to maximize the design's utility at the least cost.
Continuing with our example, a system designer might use the PC's surplus computational power to compress data as much as possible, to best exploit the limited capacity of the transmission link.
A well-designed system maximizes achievable performance while still satisfying the resource constraints.
