Mastering Non-Functional Requirements

Key drivers

The key drivers are as follows:

• The code base of the application is large, unmanageable, complex, brittle, and refactoring is burdensome due to regression
• Lack of documentation hinders usage and future upgrades
• Implementation does not have an automated regression test framework
• Extreme dependencies among tiers, layers, and components, and incorrect coupling of classes prevents replacement and updates, and can cause changes to flow through the entire system
• Leveraging direct communication prevents changes to the physical architecture i.e layers, tiers, and components
• Interdependency on bespoke applications of features such as authentication and authorization prevents reuse and hampers maintenance
• The implementation of components ...
