Final answer:
Clause 5 of the IEEE Std 1362 ConOps Document includes operational policies, description of the system, and modes of operation but not the proposed design method of the system.
Step-by-step explanation:
In the IEEE Std 1362 Concept of Operations (ConOps) Document, Clause 5 covers the Concepts for the Proposed System. Within this clause, what is fundamentally not included is the proposed design method of the system. Clause 5 typically details the operational policies and constraints, a thorough description of the proposed system, and the various modes of operation. However, the actual design method or process used to construct or implement the proposed system is not the focus of this section and therefore usually not included.
Considering the case study provided, where the design team faced a dilemma between the environmental advantages and consumer comfort, it illustrates the complexities involved in the design decision-making process. When two proposed designs rank highly based on certain criteria like low pollution, renewable energy use, and cost-effectiveness, but fall short in terms of customer comfort, the team realizes they might need to revise their design criteria or revisit earlier steps in the design process.
