Complex software systems tend to be very large nowadays. For instance, a modern car contains more than 100 million lines of code and it is expected to increase to 1 billion lines the next few years due to autonomous driving and security measures in the code. Imagine that 100 million lines of code is a book of about 1.8 million pages of text if printed out. Who is able to maintain such a vast amount of pages?
Measure Your Software Maintainability
With this in mind, it shouldn’t come as a surprise that the maintenance costs of a software system take about 90% of the total software lifetime costs. In conclusion: maintainability is an important quality characteristic that needs to be taken seriously.
The TIOBE TÜViT Trusted Product Maintainability ISO/IEC 25010 Quality Model is a pragmatic way to get an overview of the maintainability of software code before release, or even earlier, during the software development process. The indicator uses well-known code quality metrics. The model defines how the quality metrics are measured and how the outcome of the resulting measurements should be evaluated. Based on this, a software system is labelled between A and F. These levels represent descending quality levels in terms of software maintainability.
TÜViT approved TIOBE as a testing laboratory for evaluations of software products against the TIOBE/TÜViT Trusted Product Maintainability ISO/IEC 25010 Quality Model. This means that together with TÜViT, TIOBE can support you in getting your software to a certified level of Trusted Product Maintainability.
