Guiding Principles

Brad Mohs and I worked on these principles for several weeks attempting to strike the right balance of terms and coverage of concerns.

I’m quite happy where we landed on this, but I do expect this to evolve over time.

Technology guiding principles

  • scalable: design and implement to be dynamically scaled
  • learnable: short time to meaningful contribution for new team members including: documentation needed for self motivated engagement
  • reliable: system continues to operate properly in the event of one or more component failures
  • recordable: data recorded to provide meaningful business metrics and playback
  • supportable: simple and quick to get from issue notification to identification to resolution
  • automated: Humans only do what computers can’t
  • testable: design for unit, functional, security and load testing
  • consumable: interfaces into our systems will be simple and intuitive

Business guiding principles

  • secure: pci compliance and pii best practices
  • fast: systems. time to market. updates. bug fixes
  • serviceable: built to be used
  • evolvable: adapt, grow and create products/services as the business needs
  • malleable: products/services/outputs fit the varied needs of our customers/clients
  • observable: the business must know how our systems are performing: accurate sales reporting, insightful system monitoring and meaningful notification system
  • reviewable: ability to visually confirm before promoting to production. multi-tenant: single instance serves multiple tenants
