The More Things Change, the More They Stay the Same.

Systems and software engineering have come full circle.

For decades, we've taught engineers how to write better specifications using use cases, object-oriented methods, UML, and SysML. These techniques are all still relevant.

Now, we're also teaching engineers how to use AI to develop and refine those specifications. Modern specification languages, including SysML v2, can be exchanged not only between engineering tools, but increasingly with AI agents.

AI-Assisted MBSE has pioneered the use of AI to rapidly develop high-quality specifications for systems and software engineering.

Training

Parallel Agile offers hands-on training for systems and software engineers adopting AI.

Our training follows two complementary learning paths.

The AI-Assisted curriculum includes separate courses for systems and software engineering.

AI-Assisted MBSE teaches engineers how to use AI to rapidly develop high-quality specifications and SysML models for systems engineering.

AIM for Software applies the same specification-driven approach using AI coding agents. As it turns out, spec-based coding makes extensive use of use cases.

The Pain-Free curriculum is different.

It focuses on helping engineers recognize and avoid the high-pain practices that have given UML and SysML a bad reputation for being overly complicated and expensive.

Pain-Free MBSE teaches engineers how to build rigorous SysML models without killing the project in the process. We use value-to-pain ratio (VPR) to help identify the high-pain practices.

The goal is rigorous engineering done easily without getting stuck—in other words, rigor without the mortis.

Pain-Free Use Case Modeling addresses a related problem. Projects have an unfortunate tendency to skip use case modeling altogether or describe only the sunny-day scenarios. Failing to identify off-nominal scenarios results in undiscovered requirements and poor test coverage.

It's not the first 90% that kills you—it's the second 90%.

The same lesson applies to vibe-coded projects: the "second 90%" is all about the off-nominal scenarios.

Books

More than three decades of thought leadership in software and systems engineering.

The ideas behind our training and consulting have been developed, refined, and published through a series of books covering use cases, object-oriented methods, testing, project management, MBSE, and AI-assisted engineering.

Together, these books form an integrated body of knowledge that continues to evolve with—and help pioneer—the industry. The latest additions—AI-Assisted MBSE and Pain-Free MBSE—extend that foundation into the era of AI-assisted and specification-driven engineering.

Consulting
