Promising, experimenting with this on one or more teams TRIAL https://www.thoughtworks.com/insights/blog/using-thoughtworks-technology-radar-track-governance Proven to work within this organisation, well supported ADOPT Evaluating for potential experiments, under active research ASSESS Deprecated, don't start new projects using this HOLD Level of guidance
Business Goals are connected Architecture Characteristics are defined Decisions Records are documented Default Practices are documented and evolved Architecture Principles are continuously discussed, understood and evolved Building blocks of a Guidance-based approach
guide serve as deciding principle have decisive influence Exert a determining or guiding influence rule foster learning culture to govern telling people what to do
“Harness the power of defaults” “Show that most people perform the desired behaviour” “Prompt people when they are likely to be most receptive” “Design rewards and sanctions for maximum effects”
