What is the Tech Radar?
The Harborn 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 and we
consider our core technologies. We are, or aim to, specialists in these technologies. ADOPT
technologies are considered to be safe choices within Harborn, as long as the use case fits
the technology of course. Knowledge about the technology is widespread and the technology has
been used successfully several times.
- TRIAL — Technologies that we have seen work with success in project work to
solve a real problem. These technologies may be on their way to ADOPT or technologies we
consider useful and sensible choices for real projects, but where we do not aim to be or
consider ourselves specialists (yet). 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 or actual implementations in non-critical
features of real projects.
- 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 Harborn 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 and the open source
tech radar of Zalando, 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.
How do we maintain it?
The Tech Radar is maintained by our Technical Leads — who facilitate and drive the
technology selection discussions at Harborn across the teams. Assignment of technologies
to rings is the outcome of discussions with all our developers, engineers, ux-ers and any other Harborner who wishes to join.
The Tech Radar is open for contribution for all teams at Harborn and depends on their active participation to
share lessons learned, pitfalls, and contribute to good practices on using the technologies.
