Psychological Safety: Models and Experiences

Speaking of culture, I've often thought that trust builds a healthy software delivery pipeline. Without trust, bureaucracy prevails. Teammates inject themselves into points of the delivery pipeline where they have no place. This post takes the idea much farther with additional pre-requisites for psychological safety, which facilitates continuous delivery:

  • Security
  • Autonomy
  • Fairness
  • Esteem
  • Trust
  • You (your personality and biases)

Software Quality, Bugs, and SLAs

This post provides a prioritization framework for software bugs. The framework derives a Service Level Agreement (SLA) from the number and priority of bugs in a backlog. Have too many high-priority bugs? Back off feature work and start squashing!

Announcing Distributed Application Runtime (Dapr)

Dapr is "an open-source project to make it easier for every developer to build microservice applications." This project solves common distributed application problems like state management, resilient method calls, and event handling. Microservices, done correctly, provide a loosely coupled architecture, which is a tenet of continuous delivery. Please note: Dapr pushes a lot of opinions, like k8s.

Here's a case study, via code, of how to build a real-world, serverless application. This code uses AWS, but you can extract analogies to the other cloud providers.
