CPSA® Advanced Level & Domain-Driven Design: Building Real Architectural Competence

In this interview, Dr. Carola Lilienthal – Curator of the CPSA® Advanced Level Module “Domain-Driven Design (DDD)” and long-standing member of the iSAQB community – shares her perspective on the value of iSAQB training and certification for both individuals and companies.

She explains why standards in software architecture education matter, how the CPSA® Foundation and Advanced Levels differ, and what makes the Advanced Level certification a true proof of architectural compe­tence. Carola also provides deep insight into the philosophy behind Domain-Driven Design (DDD) and why it is far more than a technical technique – but rather an approach that connects software closely to business reality.

From vendor indepen­dence and standardized termi­nology to rigorous certification processes and networking oppor­tu­nities, the interview highlights how iSAQB supports sustainable profes­sional devel­opment in software architecture.

Key Takeaways

Why standards matter in software architecture
iSAQB was founded to create a shared body of knowledge and common termi­nology for software architecture. Standardized language and concepts signif­i­cantly improve commu­ni­cation within and across companies.

A clear structure: Foundation and Advanced Level
The Foundation Level provides a broad, practice-oriented intro­duction to software architecture. The Advanced Level builds on that foundation with specialized modules and requires 70 credit points, a written architecture assignment, and an expert review.

Advanced certification as proof of real competence
The CPSA® Advanced Level certification is demanding and practice-based. Candi­dates must solve a realistic architectural challenge and defend their solution – making it a respected and meaningful credential.

Indepen­dence ensures quality
iSAQB separates curriculum devel­opment, training providers, and certification bodies into three independent parties. This structure safeguards neutrality, high quality standards, and vendor independence.

Domain-Driven Design as an approach, not a method
DDD helps archi­tects move beyond purely technical thinking. It empha­sizes deep under­standing of the business domain, user needs, and the creation of a shared ubiquitous language between business and IT.

Bridging academia and real-world practice
While univer­sities teach technical funda­mentals, iSAQB training focuses on practical challenges: stake­holder commu­ni­cation, decision-making, and handling complexity in real projects.

Learning, networking, and profes­sional growth
Advanced Level trainings provide not only knowledge, but also exchange with archi­tects from different companies and domains. Confer­ences, meetups, and community engagement further strengthen profes­sional development.

Carola also reflects on her motivation to shape the DDD curriculum and contribute to iSAQB’s mission: fostering high-quality, technology-neutral education that empowers archi­tects to design better systems – and to commu­nicate their decisions with clarity and confidence.

This interview is a must-watch for anyone consid­ering the CPSA® Advanced Level, exploring Domain-Driven Design, or looking to strengthen their architectural expertise through struc­tured, community-driven education.
