Question 3 (4 points) A scenario could include much more, depending on its application and intended purpose. They come in all sizes, from a short, graphic description of a few pictures to hundreds of pages of text and data. Even though the operational scenarios developed during this phase are frequently not considered a part of the formal operational requirements document, in complex systems, they should be an essential input to the concept exploration phase. Key tenets (critical factors) relative to operational scenarios include (select all that apply): The model also needs to contain information for life cycle costing. Only by visualizing the complete life of the projected system can valid requirements and associated costs be developed Scenarios should include not only the active operational interactions of the system with its environment but also the requirements involved in its transport, storage, installation, maintenance, and logistics support. Operational requirements must initially be described in terms of operational outcomes rather than system performance. They must not be stated in terms of implementation nor biased toward a particular conceptual approach. Analyzing and formulating the functional design of the system (what actions it needs to perform) and selecting the most advantageous implementation of the system functions (how the actions can best be physically generated)
