Cooking Something Good with DevOps
This is the final piece of a three-part series introducing the Principles and Value of DevOps. I am excited and relieved that after 15 years of trying to discover, learn, apply, and teach these practices, that we have matured so that it’s clear: what principles we should apply how to guide the application of those
Principles of DevOps
DevOps will help you optimize the delivery of services that are built on technology _and improve the services_ themselves.
Mapping a Safer, Faster IAM Development and Review Process
I used Wardley mapping this morning to explore ideas I have for improving the development and review of AWS Identity and Access Management (IAM) policy changes. I’d like to share the internals of that mapping process with you to give you an illustrated example. The purpose of this process improvement effort is to help people
Learning to evolve strategy with Wardley mapping
I think Wardley Mapping is a fascinating and effective way to describe a system and develop a strategy to evolve it. Wardley Mapping has a growing community of practice with many ways to learn and participate. Here are the ones I know about (and I’d love to hear about more): Online Simon Wardley’s tweets about

The previous post introduces using Cynefin to understand systems and make good decisions. Situational Awareness: Building, Shipping, and Running Applications What kind
Making Sense of Systems and Good Decisions
Cynefin is a framework created by Dave Snowden to help people understand systems and assist decision-making. Cynefin identifies five domains from which people can analyze a system or situation: Obvious, Complicated, Complex, Chaotic and Disorder.

What is in a System?
Let’s take a step towards understanding and building “Systems.” My favorite Systems Engineering textbook defines a System as: a set of components which are related by some form of interaction, and which act together to achieve some objective or purpose. Components are simply the individual parts, or elements, that collectively make up a system. Relationships
