What is the Tech Radar?
The Holidu Tech Radar is a list of technologies, complemented by an assessment result, called ring
assignment. We use four rings with the following semantics:
- ADOPT — Technologies we have high confidence in to serve our purpose, also in
large scale. Technologies with a usage culture in our Holidu production environment, low risk and
recommended to be widely used.
- TRIAL — Technologies that we have seen work with success in project work to
solve a real problem; first serious usage experience that confirm benefits and can uncover
limitations. TRIAL technologies are slightly more risky; some engineers in our organization walked
this path and will share knowledge and experiences.
- ASSESS — Technologies that are promising and have clear potential value-add
for us; technologies worth to invest some research and prototyping efforts in to see if it has
impact. ASSESS technologies have higher risks; they are often brand new and highly unproven in our
organisation. You will find some engineers that have knowledge in the technology and promote it, you
may even find teams that have started a prototyping effort.
- HOLD — Technologies not recommended to be used for new projects. Technologies
that we think are not (yet) worth to (further) invest in. HOLD technologies should not be used for
new projects, but usually can be continued for existing projects.
What is the purpose?
The Tech Radar is a tool to inspire and support Engineering teams at Holidu to pick the best
technologies for new projects; it provides a platform to share knowledge and experience in technologies,
to reflect on technology decisions and continuously evolve our technology landscape. Based on the pioneering work of ThoughtWorks, our Tech Radar sets
out the changes in technologies that are interesting in software development — changes that we
think our engineering teams should pay attention to and use in their projects.
