Identify the Most Relevant Issues to Fix

Using Sonargraph to analyse a large code base usually reveals a lot of issues. The “System Diff” helps to keep the quality level by highlighting new and worsened issues as described in a previous blog post. But up to now there has been no recommendation about which of the already existing issues should be fixed first.
The new “Ranking” view available in Sonargraph 11.5 does exactly that and this blog post describes how it works.

Motivation for Code Quality

The main idea behind Sonargraph has always been to provide a tool that eases the creation and maintenance of high-quality software. For any serious project that must live longer than a couple of months, it is actually cheaper to spend a part of your resources to keep your software constantly at a good level of quality than using all your time to create new features. Martin Fowler explains this very well in his article “Is High Quality Worth the Cost?”. The bottom line is, that apart from the very early development stages, high-quality software is actually cheaper to develop, because it allows adding new features at almost constant speed, whereas it becomes more and more time consuming to add new features into a code base with low quality. According to our experience the most successful teams spend about 15% to 20% of their time on code hygiene.

We at hello2morrow believe that a consistent architecture is a fundamental part of software quality. When we use the term “architecture”, we think of it in terms of the IEEE 1471 standard:

“The fundamental organization of a system embodied in its components, their relationships to each other, and to the environment, and the principles guiding its design and evolution.”

This blog post describes why architectural design as an activity is needed, why conformance checks need to be done automatically by a tool and how Sonargraph supports you as a developer and architect during these activities.

Efficiently Track the Quality of a Code Base

Sonargraph offers a wide range of checks for different aspects of software quality: Architecture, metric thresholds, cyclic dependencies, duplicate code, etc.
When Sonargraph gets introduced for software projects that have been developed a couple of years, chances are high that hundred’s of issues are reported. But getting flooded with issues and sifting through them at regular intervals is neither efficient nor really helpful. Instead, you want to get a quick overview whether or not the quality is going into the right direction.

And this is where quality gates come into the game: they allow focussing on the information important to you.

This blog post details how this functionality is implemented in Sonargraph.
