MBASE

Model-Based Architecture and Software Engineering (MBASE) in software engineering is a software development process developed by Barry Boehm and Dan Port in the late 1990s. MBASE focuses on ensuring that a project's product models (architecture, requirements, source code, 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's Anchoring the Software Process.

## History

Over the three years (1995 to 1998) of developing digital library products for the libraries at University of Southern California (USC), Barry Boehm and Dan Port had been evolving an approach called Model-Based (System) Architecture and Software Engineering (MBASE).
