What is this?

The FEXCO Central API Tech Radar is a list of software related technologies, complemented by an assessment result, called ring assignment as categories. We use four rings with the following semantics:

  • ADOPT — Technologies we have worked in the past, have high confidence in to serve our purpose, also in large scale. Technologies with a usage culture in FTS production environments. We are not thinking of discard these technologies yet.
  • 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. Technologies we have tested in PoCs with a TRIAL technologies are slightly more risky; some engineers in FTS walked this path and will share knowledge and experiences.
  • ASSESS — Technologies that are promising and have clear potential value-add for us that we test in PoCs; 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 the 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. ASSES technologies can be never adopted depending on the results from PoCs
  • HOLD — What we used in the past and we should not use anymore for any reason. Technologies not recommended to be used for new projects. HOLD technologies should not be used for new projects, but usually can be continued for existing projects with a specific deadline for replacement.


The FEXCO Central API Tech Radar is one of the pieces with useful information for integration, SRE and developments teams and squads. Engineering teams can use it to be aware about our needs regarding training, skill sets, evolution, etc; it provides a platform to share knowledge and experience in technologies, to reflect on technology decisions and continuously evolve our Technology Landscape reflected on common platforms. Based on the pioneering work of ThoughtWorks, the FTS Software 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 consider using in their projects.
