What Is the International Software Architecture Qualification Board and Its Certifications?

Software architecture is an extremely young discipline, and, despite many publications on the subject, various opinions still exist regarding its precise scope and design in the context of computer science and information technology.

 

The tasks and responsibilities of software architects are defined in very different ways and are subject to continual renegotiation during a project.

 

In contrast, software engineering disciplines such as project management, requirements engineering, and testing have a more mature knowledge base. Various independent organizations offer training curricula that clearly define the knowledge and skills required by these disciplines (for testing, visit www.istqb.org; for requirements engineering, visit www.ireb.org; for project management, visit www.pmi.org).

 

In 2008, a group of software architecture experts from the business, industry, and scientific communities formed the International Software Architecture Qualification Board as a registered association under German law (iSAQB e.V., www.isaqb.org). The goal of the iSAQB is to define product- and manufacturer-independent standards for the training and certification of software architects. Certifications at Foundation, Advanced, and Expert levels allow software architects to certify their knowledge, experience, and skills using a recognized procedure.

Because it eliminates the terminological uncertainty referred to earlier, standardized training benefits established and aspiring software architects, companies, and training organizations. Precise training curricula are essential for the examination and certification of aspiring software and ensure that high-quality training is available on the basis of an accepted canon of knowledge.

 

Certification as a Certified Professional for Software Architecture (CPSA) is carried out by independent bodies. CPSA Foundation Level certification is based on a subset of a nonpublic catalogue of demanding questions developed by the iSAQB and matched to the curriculum. Advanced Level certification also requires practical certification and participation in licensed training courses (or acknowledgement of equivalent non-iSAQB qualifications). Expert Level certification is currently in development.

 

Various licensed training institutions offer multiday courses designed to refresh and deepen candidates’ existing knowledge in these subject areas. Participation in a course is recommended but isn’t a prerequisite for registration for the certification examination.

 

Certified Professional for Software Architecture – Foundation and Advanced Level

The iSAQB has now defined clear certification guidelines for CPSA Foundation Level and Advanced Level certification.

 

Advanced Level certification is modular and consists of individual courses dedicated to specific core competences for IT professionals:

  • Methodical competence: Technology-independent skills for systematic approaches to IT projects
  • Technical competence: Skills in the use of technology for solving design tasks
  • Communicative competence: Communication, presentation, rhetorical, and meeting skills that increase efficiency during the software development process

Prerequisites for Advanced Level certification are as follows:

  • CPSA-F (Foundation Level) training and certification
  • At least three years’ professional experience in the IT sector
  • Active participation in the design and development of at least two different IT systems
  • At least 70 credit points from all three competence areas (with a minimum of 10 credit points for each)

The examination consists of solving a prescribed task and discussion of the solution with two independent examiners.

 

Foundation Level certification is based on knowledge and skills defined in the iSAQB curriculum [isaqb-curriculum]. These are as follows:

  • The definition and importance of software architecture
  • The tasks and responsibilities of software architects
  • The role of the software architect within a project
  • State-of-the-art methods and techniques for the development of software architectures

The focus is on the acquisition of the following skills: 

  • Coordinating critical software architecture decisions with other parties involved in requirements management, project management, testing, and development
  • Documenting and communicating software architectures on the basis of views, architectural patterns, and technical concepts
  • Understanding the main steps involved in the design of software architectures and performing them independently for small- and medium-sized systems

Foundation Level training provides the knowledge necessary for designing and documenting a solution-based software architecture for small- and medium-sized systems, based on a sufficiently detailed requirements specification. This architecture can then serve as a template for implementation. Participants are trained to make problem-oriented design decisions on the basis of previous practical experience.

 

The figure below shows the content and weighting of the individual areas of the curriculum for iSAQB Certified Professional for Software Architecture (CPSA) Foundation Level training.

 

Structure of the iSAQB curriculum for the CPSA Foundation Level training

 

Various independent bodies offer certification based on the iSAQB curriculum. Examiners use standardized questions prepared by the iSAQB.

 

Questions are multiple-choice, so the results are objectively measurable.

 

The examination validates your software architecture capabilities on paper. It’s up to you to prove yourself in real-world situations.
