Those who clearly define requirements and test software professionally lay the foundation for reliable results. With IREB , clearer, testable requirements are created. With ISTQB , testing becomes predictable, risk-based, and traceable. This noticeably improves quality.
However, as projects grow in size, another question arises: How can this quality be maintained over the long term as systems expand, interfaces multiply, and new initiatives are added?
This is where IT architecture comes into play, and with it, TOGAF. After all, well-defined requirements and robust testing ensure the success of individual releases and project goals. A sustainable architecture ensures that quality isn’t limited to individual projects but remains permanently embedded in the IT landscape.
Why Quality Often Falls Short in Practice Due to Architectural Design
Many organizations provide solutions that work, yet typical problems arise over time:
• Systems become difficult to integrate because interfaces have evolved in an inconsistent manner
• Changes take longer because dependencies are unclear
• Solutions are built multiple times because there is a lack of transparency regarding existing capabilities
• Quality declines because complexity increases and no one is managing the big picture
This rarely has anything to do with poor teams. Often, there is simply no shared architectural framework to bring together decisions, priorities, and vision statements.
What TOGAF Does at Its Core, Without Getting Complicated
TOGAF is a framework for enterprise architecture. Simply put, it helps connect business and IT in a structured way, using a clear approach to vision, planning, and implementation.
In day-to-day project work, this means:
• Architecture provides direction on what should be built in the long term
• Architecture highlights dependencies before they become risks
• Architecture makes decisions transparent, rather than just discussing them
• Architecture supports roadmaps so that changes remain planable
This means that TOGAF is not a substitute for requirements engineering or testing, but rather a logical complement when organizations need to think on a larger scale.
The Bridge from the Project to the IT Landscape
Requirements and testing primarily answer these questions:
• What should be delivered
• How do we verify that the delivery was correct?
TOGAF, supplemented by the architecture perspective:
• How does this solution fit into the bigger picture?
• What capabilities, systems, and data are affected?
• How do we avoid creating new silos and technical debt?
• How do we turn individual projects into a consistent line of development?
This creates a common thread between project quality and long-term IT management.
When TOGAF Becomes Particularly Relevant
TOGAF is particularly worthwhile if at least one of the following applies:
• There are several parallel projects building on the same IT landscape
• Interfaces and dependencies are growing faster than transparency
• Cloud, platforms, and modernization projects should be planned strategically
• Business and IT need shared visions, not just individual solutions
• Governance should accelerate decisions rather than block them
