Every quarter, your inbox fills with vendor pitches promising the next revolution. Your board asks whether you should be investing in agentic AI. Your engineers want to adopt the latest framework they saw at a conference. Meanwhile, you are trying to keep production systems stable and deliver against a roadmap that was agreed six months ago.
This is the reality of modern IT leadership. The challenge is not a lack of options but an overwhelming abundance of them. What you need is a structured way to evaluate, track, and communicate technology decisions across your organisation. You need a technology radar.
What Is a Technology Radar?
The concept was popularised by ThoughtWorks, who publish their own radar twice a year. At its core, a technology radar is a visual tool that categorises technologies, tools, techniques, and platforms into four rings:
- Adopt - proven technologies your teams should be using as standard
- Trial - technologies ready for controlled use in non-critical projects
- Assess - promising technologies worth investigating but not yet ready for production
- Hold - technologies to avoid or actively migrate away from
Technologies are also grouped into quadrants, typically covering techniques, platforms, tools, and languages or frameworks. The beauty of this model is its simplicity. Anyone in your organisation can look at the radar and immediately understand where a given technology sits in your strategy.
Why IT Leaders Should Care
If you are an IT Director, CTO, or Head of Technology, a technology radar solves several problems simultaneously.
It Kills Vendor Hype
When a vendor tells you their platform is "industry-leading" and "essential for 2026," you can point to your radar. If the technology sits in Assess, that means you are watching it but not investing yet. If it is on Hold, the conversation is over. This is not about being resistant to change. It is about having a framework for evaluating change rationally, something I explored in why AI pragmatism matters more than hype.
It Aligns Engineering Teams
Without a radar, technology decisions happen in silos. One team adopts React, another picks Vue, a third builds with Svelte. Your platform team picks Terraform while another group uses Pulumi. Before long, you have a fragmented estate that is expensive to maintain and impossible to hire for.
A technology radar creates a shared vocabulary. When a technology moves to Adopt, everyone knows it is the standard. When something hits Hold, teams know to stop investing in it. This does not eliminate all divergence, nor should it, but it channels innovation in a deliberate direction.
It Makes Strategy Visible
Most technology strategies live in slide decks that nobody reads after the initial presentation. A radar is a living document. It changes quarterly. People can see what is moving, what is new, and what is being retired. This visibility is powerful for telling the story of IT value to the business in a way that resonates beyond the technology team.
It Reduces Decision Fatigue
Your senior engineers and architects make dozens of technology decisions every week. A radar gives them guardrails. If something is in Adopt, use it. If it is in Hold, do not. The grey areas (Trial and Assess) are where judgement is needed, but even there, the radar provides context that makes decisions faster.
How to Build Your Own Technology Radar
Building a technology radar is not complicated, but doing it well requires discipline. Here is a practical approach based on what I have seen work in organisations of varying sizes.
Step 1: Assemble the Right People
Your radar should not be built by one person. Form a technology advisory group that includes senior engineers, architects, team leads, and at least one person from security. Aim for six to ten people who collectively cover your technology landscape.
The key is diversity of perspective. If your radar group is entirely backend engineers, you will end up with blind spots in frontend, infrastructure, and data. Include people who disagree with each other. That friction produces better outcomes.
Step 2: Audit Your Current Estate
Before you can plot where technologies should go, you need to know what you are actually using. This means cataloguing every significant technology in your stack: languages, frameworks, databases, cloud services, CI/CD tools, monitoring platforms, and security tooling.
This audit often reveals surprises. You will find tools that three people rely on but nobody officially approved. You will discover that a "standard" technology is actually only used by one team. This reality check is valuable in itself.
Step 3: Evaluate and Place
For each technology, your advisory group should discuss and agree on a ring placement. Use these criteria:
Adopt requires evidence of successful production use in your organisation, a clear skills base, and active community or vendor support. This is not aspirational. It reflects what is working today.
Trial means you have enough confidence to use it in a real project but want more evidence before standardising. Set a time limit. If something has been in Trial for over a year without moving to Adopt, it probably should not.
Assess is for technologies you are actively researching. Someone in your organisation should be responsible for tracking each Assess item and reporting back to the group quarterly.
Hold covers two scenarios: legacy technologies you are migrating away from, and new technologies you have evaluated and decided against. Both are equally important to document. Knowing what you chose not to adopt, and why, saves repeating the evaluation later.
Step 4: Publish and Socialise
A radar that lives in a private wiki is useless. Publish it somewhere every engineer can find it. Many organisations use the open-source ThoughtWorks Build Your Own Radar tool, which generates an interactive visualisation from a simple spreadsheet.
Hold a quarterly "radar review" meeting where you present changes. Explain why things moved. Share the reasoning, not just the outcome. This transparency builds trust and encourages people to contribute to future editions.
Step 5: Iterate Quarterly
A radar that never changes is just a static list. Review it every quarter. Technologies should move rings based on real experience, not theoretical arguments. If your Trial of a new observability platform went well, move it to Adopt. If that AI coding tool proved unreliable, move it to Hold.
The quarterly cadence matters. Faster than that and you create instability. Slower and the radar falls behind reality.
Common Mistakes to Avoid
Having helped organisations implement technology radars, I have seen the same mistakes repeatedly.
Making It Too Big
Your first radar should have 30 to 50 items, not 200. Focus on the technologies where alignment matters most. Nobody needs the radar to tell them that TCP/IP is in Adopt.
Treating It as Top-Down Decree
If the radar is seen as management dictating technology choices, engineers will ignore it. The advisory group must include respected engineers, and decisions should be based on evidence and discussion, not hierarchy.
Ignoring the Hold Ring
Many organisations are reluctant to put technologies on Hold because it feels negative. But the Hold ring is arguably the most valuable. It prevents teams from accidentally adopting something you have already evaluated and rejected. It also signals intent to migrate away from legacy technologies, which is essential for managing technical debt strategically.
Not Connecting It to Strategy
A radar without context is just a list. Each item should link to your broader technology strategy. If you are placing Kubernetes in Adopt, explain how it connects to your platform engineering approach. If you are putting a specific AI framework in Trial, tie it to your AI enablement roadmap.
Scaling the Radar for Larger Organisations
In larger enterprises, a single radar may not suffice. Consider a two-tier approach: a central radar covering cross-cutting concerns (cloud platforms, security tooling, CI/CD standards) and domain-specific radars for individual product lines or business units.
The central radar sets the guardrails. Domain radars allow teams to make local decisions within those guardrails. This balance between standardisation and autonomy is crucial for organisations with more than a few hundred engineers.
Tools for Building Your Radar
You do not need expensive software. Here are practical options:
- ThoughtWorks BYOR - free, open source, generates interactive radar from a Google Sheet or CSV
- Backstage Tech Radar plugin - if you already use Backstage as your developer portal, this integrates naturally
- Simple spreadsheet - honestly, a well-maintained spreadsheet with clear columns (technology, quadrant, ring, description, last reviewed) works fine for smaller teams
- Notion or Confluence - for organisations that prefer document-based approaches, a structured page with quarterly changelog works well
The tool matters less than the process. Pick whatever your team will actually maintain.
Measuring Success
How do you know if your technology radar is working? Look for these signals:
- Engineers reference the radar in architecture decision records and pull request discussions
- New technology proposals include a suggested radar placement
- The number of "rogue" technology adoptions decreases over time
- Onboarding new engineers is faster because the technology landscape is documented
- Vendor conversations become more focused because you can articulate what you are and are not interested in
If none of these are happening after two quarters, your radar is not embedded enough in your culture. Double down on socialisation and ensure the advisory group includes people with real influence.
Getting Started This Week
You do not need permission to start a technology radar. Here is what you can do this week:
- Monday - List the 20 most significant technologies in your stack
- Tuesday - Draft initial ring placements based on your own judgement
- Wednesday - Share the draft with three to five senior engineers and ask for feedback
- Thursday - Incorporate feedback and identify the most contentious items
- Friday - Schedule a one-hour session with your advisory group to discuss and finalise
Your first radar will not be perfect. It does not need to be. The value comes from the conversation it triggers and the alignment it creates. Start small, iterate quarterly, and let it grow organically.
The technology landscape will keep accelerating. Vendors will keep pitching. Engineers will keep finding shiny new tools. A technology radar will not slow any of that down, but it will give you and your organisation a structured way to navigate it. That is what good IT leadership looks like.
