Defining Operational Concepts using SysML: System Definition from the Human Perspective

Uses cases & scenarios are an effective means of assessing system operation from the user's perspective. Rather than focus on obscure “functional requirements”, which are oftentimes elusive to grasp and difficult for the end-user to understand, this tutorial explores how an operational concept based on use cases & scenarios can be used to focus on the user's perspective of the system, with subsequent improvements in the completeness and understanding of the functional requirements. This tutorial explores why an Operational Concept document is written, what the Operational Concept is, and how it can be effectively applied on your project through use case & scenario descriptions and SysML diagramming. Tutorial includes a workshop format to apply lessons learned and discuss strategies. SysML concepts explored include use case diagrams and activity diagrams to express main use case scenarios, alternate courses, exception cases, and extension use cases.
