3.9 Developing Supplemental Performance Requirements
Three supplemental performance requirements were introduced in Chapter 2: operational suitability, supportability, and confidence. These performance requirements are part of the overall set of operations and support elements shown in Figure 3.19. Operational suitability is a measure of how well the network design can be configured, monitored, and adjusted by the customer's operators. Supportability is a measure of how well the customer can keep the system performing, as designed, over the entire life of the system. Confidence is a measure of the ability of the network to deliver data without error or loss at the required throughput.

3.9.1 Operational Suitability
Ensuring that your customer can operate the planned network is almost never an easy task and one that the customer never thinks about until asked. Two major factors influence the operational suitability: network architecture/design and the quality of the human operators.
It is possible to develop a network that cannot be operated consistently and effectively. Complex minute-to-minute adjustments can swamp even the most competent staff. The lack of any effective monitoring tools or control systems to integrate actions across geographically dispersed sites can transform the most advanced design into a dysfunctional mass of cable and computers and recriminations and lawsuits. Development of the network must consider network management that permits the operators to...
