How does Quality fit in CALMS?

Recently, I was asked to give a 15 minute introduction on Quality Strategy in DevOps for our upcoming “Efficient DevOps with SAP” course and I happily accepted. And then, to my horror of horrors, I realised that I needed to figure out what a Quality Strategy is and what makes it unique in a DevOps […]

Cheat-sheet for More Laws, Principles & the Such

A couple of months ago, I wrote up a cheat-sheet for laws, principles & the such, as a quick reference to theories or adages that I often heard referenced in software development discussions. Here is the second part, for things that I needed to look up since that first post.

Keeping Up with Compliance in a DevOps World

This post first appeared at the DevTestOps community on October 4, 2019. About 5 years ago I was working in a small product that was doing (almost) everything the DevOps way. We had the works: code and tests versioned in git, trunk based development, building the code once (more or less), feature toggles, daily deployments, […]

Some Ideas for Reducing “Release Decision” Time

Have you Tried Turning it Off and On Again? – Appreciating Your Customer Support

A long time ago I was working in customer support, spending my days speaking to unhappy customers who had purchased some sort of electronic device. People generally didn’t pick up the phone to tell us how pleased they were with their purchases. Sometimes they would call to ask for a technician, others to ask how […]

The Surprising Diversity of Password Retrieval

In the last weeks of my pregnancy the “nesting” instinct kicked in. Since I was no longer working, I had the time to do important chores, such as trying out all the pens in our household to get rid of the ones that were empty. Once I was done with the physical world, I went […]
