Insights from Operational Architecture The How

• Leverage use case diagrams (and mission threads for clarity) • Consider alternative operational concepts – an important trade space • Identify function (what), performance (how well), and behavior (conditions,

anomalous states, concurrent demands, …) • Integrate the day in the life of the system • Consolidate operational perspectives

• Consolidate scenarios and threads into composite • Identify transitions between phases of operation • Look for core process elements and patterns to build around • Stop when you • Understand dependencies with other systems • Agree & validate assumptions about “the world” • Define your boundary • Understand value of requirements that drive cost, schedule, or risk

State Transition Diagrams

• Describe the transition of the system through multiple states • Represents states, transitions that connect them, and events that trigger transitions • Orthogonal to behavior • Alternative approach to analysis / representation • If both are used, states are elaborated / realized by behavior
