| Popis: | In 2015 Northrop Grumman's GCSS-J Systems Engineering group in Mclean, Virginia, supporting the DISA GCSS-J PMO, had been sustaining and evolving a critical information service portal for 12 independent user groups accessing 22 independent systems. This web-based portal is a centralized Systems-of-Systems (SoS) hub, dealing with unpredictable independent-system changes, mitigating immediate-priority security needs, and replacing uncontrollable obsolescence of COTS software elements – all the while deploying new capability in six month increments requested by expectant users. The systems engineering process combines elements of Scrum, and contract waterfall requirements simultaneously on three release instances, one in development, one in accreditation test, and one in deployed use – with a wave-like transition among the three instances every six months. The process had six years of effective employment and evolution, winning praise from GAO and users alike. Most notable is the real-time control model for re-prioritizing work-in-process, the intimate involvement of customer and users in the agile systems engineering process, and the never-ending evolution with all life-cycle stages in simultaneous activity. |
