Mission Thread Workshops: Lessons Learned in End-to-End Capability and Quality Attribute Specification for SoS Architecture Development
Software Engineering Institute
In this presentation, we discuss lessons learned from using mission thread workshops (MTW) as an early architecture development step for a number of DoD systems of systems (SoS). The approach is based on defining a number of critical warfare vignettes, then developing some associated end-to-end mission threads that stress the envisioned capabilities of the SoS, and finally, augmenting these threads with quality attribute and capability considerations elicited from the SoS and system stakeholders in a facilitated workshop. The MTW explores these threads with the stakeholders in a number of half-day or full-day sessions to determine gaps in the functional and non-functional capabilities (e.g., performance, availability, usability, security) at each step. Architectural challenges are then derived from the resulting augmented threads, and these can be used to drive follow-on efforts, such as building the DoDAF views and products. We will also discuss integrating this type of approach into a program's architecting process and acquisition plan.
