DAARIUS methodology
The DAARIUS methodology is a structured, scalable and team-based system design methodology. It provides a traceable underpinning for key design decisions and uses the simple executable models available in systems engineering.
The benefits of the DAARIUS methodology are that:
it quickly provides a system overview with an understanding of what is key and where the trade-offs lie
it enables an understanding of the business and system consequences of system design decisions via explicit reasoning
it delivers a systematic system design approach with a consistent system representation
Within organizations, complexity is increasing at multiple levels: business, system, technology, process and organizational. In this increasingly complex environment, the challenge is to make business-critical decisions. This requires reasoning on system aspects/qualities across disciplines and departments.
The DAARIUS methodology offers a systematic, team-based way of working. This includes capturing and organizing existing knowledge within an organization. This knowledge can be decomposed into a central set of system views, stakeholder views, individual domain views and building block views. In these views, ownership of these parts of the system can be explicitly defined. Between these views, the relations and dependencies can be made explicit using selected parameters of the system. The use of simple, executable models is leveraged for analysis in order to make trade-offs and decisions. The captured knowledge and its relationships and analyses enable clear communication and collaboration across disciplines within the system design team.
The DAARIUS methodology consists of a method, a structure, a language and the DAARIUS tool. The language is the formalism used to express the system in the system structure. The structure restricts and organizes the information to keep it understandable, provides multiple levels of abstraction and contains views for the knowledge domains. The DAARIUS method describes the steps to come to this organized information. Finally, the DAARIUS tool supports the formalism and the structure such that information can be recorded in order to reduce the storage effort while supporting executable models.
