In this presentation, we will 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. Each MTW results in a
set of challenges being developed during the follow-on activity.
have reviewed and organized the challenges from 46 of these mission
threads and found a surprisingly consistent overlap of the challenges
developed, which are usability/automation, capability gaps, resource
management, training, migration of legacy systems, and collaboration.
The presentation will describe each of these general challenges in
