Agile-Lean Software Engineering (ALSE) Evaluating Kanban in Systems Engineering

Abstract : This research project evaluates the use of on-demand (pull or kanban) scheduling approaches in systems engineering (SE). Such approaches have been seen to be valuable in software system development. In particular, the research focuses on SE where rapid response software development projects incrementally evolve capabilities of existing systems and/or systems of systems. Phase I considered the problem and possible applications of alternative scheduling methods and suggested possible outcomes of on-demand scheduling coupled with a service-oriented approach to SE. It defined a conceptual model and developed initial simulations to capture the model and better understand the impact. Phase II focuses on applying the method to multi-level service-based SE in complex systems of systems. Using the models and simulations from Phase I, Phase II defines a prototype network of kanban-based scheduling systems (KSS) for a target environment based on a large multi-facility hospital system. The definition is simulated to demonstrate its behavior. Follow on work is planned to use the prototype in comparing performance with traditional SE methods. This will enable determination if SE functions are accomplished more effectively and efficiently, whether the overall value of the systems of systems over time is increased, and whether other expected results are fulfilled.
