I‐SHARE – INCOSE Systems Heuristics Application Repository: Sharing Systems Engineering Knowhow and Experience

Abstract Systems engineering (SE) is a transdisciplinary discipline that links all the engineering disciplines involved in defining a system throughout its lifecycle. As such, SE involves heuristics to a significant extent. A heuristic relates to a formulation based on experts' experience serving as a guide in the investigation or solution of a problem. To be usable, heuristics should be memorable and pithy. A team of INCOSE Fellows created the INCOSE Systems Heuristics Application Repository , or I‐SHARE in short, in which over 600 SE‐related heuristics are curated and shared, covering subjects that include SE competencies, lifecycle stages, expertise, operational domains, and system attributes. In this paper, we describe the I‐SHARE, the motivation and stages of its creation and compilation, and ways through which this knowledge base can be an invaluable service to the SE community.
