Decision Oriented Systems Engineering (DOSE) – A Structured, Systematic Approach to Function Allocation

摘要

Perhaps the most important reason Systems Engineering exists as a discipline liesrnin the observation that complex systems cannot be treated merely as an assemblage of so manyrnbuilding blocks. Systems Engineering employs techniques and practices that attempt to considerrnthe whole throughout the design process. Systems Engineering offers quite an assortment ofrnprocesses, and tools devices to capture, describe, derive, and otherwise characterize variousrnaspects of systems under design or analysis. There are many evolving Systems Engineeringrnprocesses and practices, including processes in which the object-oriented paradigm dominates.rnUnfortunately, the set of available processes, models, and tools remains weakest where they arernneeded the most: where decision tradeoffs are most negotiable, where “requirements” are not yetrnfirmly established, where the use of legacy systems can have the greatest impact, and where thern(projected) life cycle impacts of such decisions are greatest.rnThis paper describes a new system development practice named Decision Oriented SystemsrnEngineering (DOSE). If consistently and diligently applied in tandem with other morernconventional practices, DOSE provides a solid Systems Engineering “hook” to the application ofrnHuman Systems Integration principles and offers considerable promise in simplifying the designrnof even the most complex systems involving teams working with mixes of new, evolving, andrnlegacy systems.
