This blog is about an important principle for improving the quality of documentation. It can also help to improve decision making, collaboration and more effectively use meeting time by leveraging written asynchronous communication. Documentation (e.g. Architecture Documentation, Good Practices and Product Documentation) should be treated as code, which means that it is: placed under version control very simple syntax changes undergo reviews....
An agile approach involves cross-functional teams where individual team members complement each other’s skills. With the move to cloud-based development, teams must often deal with increasing complexity and must learn quickly. Both aspects bring up new challenges when it comes to growing the necessary skills. This blog introduces some problems in empowering the teams to....

Static application security testing (SAST) is a common essential step in the development lifecycle of large software companies like SAP. It enables detection of critical vulnerabilities in an application source code before deployment, when fixing the problem is the least expensive. While SAST have many known limitations, the impact of coding style on their ability....
