Agile Model-Based Systems Engineering 71% Faster Than Document-Based Approach

At the same time, adapting and implementing MBSE in an agile software development environment is not as easy as including MSBE tasks in sprints and a scrum framework. It requires iterative modeling processes, changes in modeling standards, frequent interactions with model stakeholders, and effective interfaces between MBSE and agile tools (e.g. Cameo Systems Modeler and Jira).

A different approach is required. Agile MBSE is the tailoring of MBSE methodologies, processes, and modeling techniques to ensure effective integration and use of MBSE in an agile environment.

Rite-Solutions has developed an Agile MBSE strategy, described in a series of whitepapers, presentations, and models, based on three critical items:

• Modeling techniques, standards, processes, guiding principles, and best practices required to ensure a clear, efficient, and trouble-free transition from DBSE to Agile MBSE.
• Interface options for Cameo Systems Modeler and Jira. These interface options are also applicable to other MBSE tools (i.e. Enterprise Architect and Rational Rhapsody).
• Clear value proposition to garner stakeholder support and make a smooth transition from DBSE to Agile MBSE.

Part of the Agile MBSE strategy also includes templates for generating deliverables and compliance documents. Unlike a document-based system, this can be done while providing rigorous, precise, agile, data-centric, and fully connected models to a wide variety of stakeholders.

MBSE is not totally new. The industry has had tremendous success using MBSE. The challenge for some organizations is that it requires an investment up-front. But, once the models are set up, they can be used for the rest of the system’s lifecycle, which can span decades.

In a recent implementation case study, two of our software development teams worked on the same project in parallel. One used document-based systems engineering methods, the other used Agile MBSE. Both teams tracked the time it took, using Jira, to complete tasks. The end result was a staggering 71% reduction in labor hours using Agile MBSE compared to the document-based approach!

Rite-Solutions has also used Agile MBSE with clients, most recently on a combat control system. Because of the tremendous upside, we have institutionalized our approach to MBSE, which allows government clients to focus on their core competency of agile software development.
