What makes software complex?

• Too many moving part - is the complexity worthed? (ex: microservices)
• Excessive configuration
• Unnecessary components
• Too many layers
• Brittle
• Error prone
• Hard to deploy
• Hard to test
• Hard to reason
• Uncontrollable mutability
• Excessive dependencies - dependencies are hard to maintain and become incompatible
• Technology infatuation & Resume driven development - frequently adding new technologies without business value
• Lack of reversibility - The ability to back out of design/architectural decisions
  • Frameworks - the framework calls to your code and your code calls to the. framework
  • Libraries - easier to reverse than a framework
    • “Using a library is like dating, using a framework is like a marriage”
