As a Senior Software Engineer, my employers and customers have always had high expectations of my skills to deliver high-quality software. But when I asked them to define and describe what "high-quality" means, there was always a missing point in their answers: performance.

What high-quality software is:

Why Scrum could be a successful way to create high quality software?

Based on my experience, any "high-quality" software can only be described as is if it applies the following list of 10 points, but not necessarily in the same order:

  • Functionality: The software exhibits completeness by accurately meeting all specified requirements and providing intended features. It performs functions without errors, ensuring precision and reliability in its results.
  • Reliability: Ensuring stability, the software operates consistently under varying conditions, avoiding unexpected crashes or failures. It exhibits fault tolerance, gracefully handling random inputs or system failures without compromising overall performance.
  • Performance: The software is characterised by prompt responsiveness to user inputs and efficient task processing. Its scalability allows it to handle increased workloads and user demands without significantly decreasing performance.
  • Usability: The user interface (UI) is intuitive, easy to navigate, and aesthetically pleasing. The positive user experience (UX) allows users to accomplish tasks with minimal effort.
  • Maintainability: Code readability and organisation facilitate future modifications and updates. The software is structured into modular components, promoting easier maintenance and code reuse.
