Model-Based Architecture and Software Engineering (MBASE) in software engineering

Software engineering

Software Engineering is the application of a systematic, disciplined, quantifiable approach to the development, operation, and maintenance of software, and the study of these approaches; that is, the application of engineering to software...

Software development process

A software development process, also known as a software development life cycle , is a structure imposed on the development of a software product. Similar terms include software life cycle and software process. It is often considered a subset of systems development life cycle...

Requirement

In engineering, a requirement is a singular documented physical and functional need that a particular product or service must be or perform. It is most commonly used in a formal sense in systems engineering, software engineering, or enterprise engineering...

In computer science, source code is text written using the format and syntax of the programming language that it is being written in. Such a language is specially designed to facilitate the work of computer programmers, who specify the actions to be performed by a computer mostly by writing source...

, etc.), process models (tasks, activities, milestones), property models (cost, schedule, performance, dependability), and success models (stakeholder win-win, IKIWISI - I’ll Know It When I See It, business case) are consistent and mutually enforcing.

MBASE is an approach to the development of software systems that integrates the system’s process (PS), product (PD), property (PY) and success (SS) models, models that are documented in the following system definition elements (also referred to as “artifacts” or “deliverables”):

• Operational Concept Description (OCD)
• System and Software Requirements Definition (SSRD)
• System and Software Architecture Description (SSAD)
• Life Cycle Plan (LCP)
• Feasibility Rationale Description (FRD)
• Construction, Transition, Support (CTS) plans and reports
• Risk-driven prototypes

The essence of the LeanMBASE approach is to develop the system definition elements concurrently, through iterative refinement, using the risk-driven, three-anchor point, Win–Win Spiral approach defined in Boehm
