With the growing challenge of maintaining more and more code, maintainability is an important quality characteristic that needs to be taken seriously.
The TIOBE TÜViT Trusted Product Maintainability ISO/IEC 25010 Quality Model (click here for full definition) is a pragmatic way to get an overview of the maintainability of software code. This Quality Model has been developed in close cooperation between TÜViT and TIOBE. Following ISO/IEC 25010, the quality model drills down from the quality characteristic maintainability towards the sub-characteristics modularity, reusability, analyzability, modifiability and testability. To objectively measure maintainability, the following 5 metrics are defined:
Based on this, a software system is labeled between A and F, indicating how maintainable the code is. If a software system reaches level C for Trusted Product Maintainability according to this model, it is eligible for an official TÜViT certificate.
