How to Propose a Tech Radar Entry in English

A tech radar — popularised by ThoughtWorks — is a shared document tracking which tools, languages, and practices a team should adopt, trial, use with caution (“hold”), or stop using entirely. Proposing a new entry means making a case in English precise enough that other engineers, who may not have used the tool themselves, can evaluate your recommendation fairly and act on it consistently.

Key Vocabulary

Ring (Adopt / Trial / Assess / Hold) — the four typical categories a tech radar entry falls into, representing a maturity and confidence level rather than a strict popularity ranking. “I’m proposing this move from ‘Assess’ to ‘Trial’ — we’ve used it successfully on one internal service and want broader validation before recommending it for adoption.”

Adopt — a strong recommendation to use this by default for new projects, backed by demonstrated success across the organisation.

Trial — worth pursuing on a real project, understanding the risks, but not yet proven enough for a blanket recommendation.

Assess — worth exploring to understand its potential fit, but not yet ready to be used on anything beyond a spike or prototype.

Hold — proceed with caution; this includes newly deprecated or high-risk technologies the team should avoid adopting further, even if some legacy usage remains.

Blip — the individual entry itself (a specific tool, technique, platform, or language) being placed on the radar. “This blip covers our evaluation of the new ORM — I’ve included both the benchmark results and the migration cost estimate.”

Structuring the Proposal

• What it is: “[Tool name] is a [category] that [core function], commonly used for [use case].”
• Why we’re considering it: “Our current approach has [specific pain point] — this tool addresses that by [mechanism].”
• Evidence so far: “We ran a two-week spike using it on [service], and saw [specific measured outcome].”
• Recommended ring and rationale: “I’m proposing ‘Trial’ rather than ‘Adopt’ because we haven’t yet validated it under production load.”
• Risks and open questions: “The main risk is vendor lock-in — before broader adoption, we should confirm there’s a viable migration path away from it if needed.”

Presenting to the Architecture Group

• “I’d like to propose we move [tool] from ‘Assess’ to ‘Trial.’ The prototype showed a 40% reduction in boilerplate for this specific use case, and I think it’s worth validating on a real service.”
• “This isn’t a proposal to migrate everything — I’m suggesting we allow one team to trial it on a low-risk service and report back in a quarter.”
• “I want to flag this as a ‘Hold’ rather than remove it from the radar entirely — some teams still depend on it, and I don’t want this to read as an urgent migration mandate.”

Handling Disagreement

• “I hear the concern about operational overhead — could we scope the trial narrowly, to just the reporting service, so the blast radius is limited if it doesn’t work out?”
• “That’s a fair point about the learning curve. I’d suggest we pair the trial with a short internal workshop so the team isn’t learning it entirely on their own.”
• “I don’t think we have enough evidence yet to move this to ‘Adopt’ — I’d rather keep it at ‘Trial’ for another cycle and revisit with more data.”

Professional Tips

1. Anchor the recommendation in evidence, not enthusiasm. “I really like this tool” is a weaker argument than “this cut our build time by 35% in a two-week spike.”
2. Be explicit about scope. A trial recommendation for one low-risk service reads very differently from an unscoped “let’s use this everywhere” proposal.
3. Always note the risks alongside the benefits. A one-sided pitch tends to get more scrutiny in review, not less — naming the trade-offs upfront builds credibility.

Practice Exercise

1. Write a one-paragraph pitch moving a tool from “Assess” to “Trial,” including one piece of concrete evidence.
2. Draft a response to a colleague who disagrees with your proposed ring, offering a scoped compromise.
3. Write a short “Hold” entry for a tool your team is deliberately moving away from, without sounding alarmist.

Navigating Nuance: Speaking Professionally When Your First Language Isn’t English

Okay, you’ve crafted a solid tech radar entry – outlining the benefits of adopting a new testing framework, for instance, and suggesting it be trialed. You’ve used clear language, focused on impact, and presented a logical case. But now comes the crucial part: communicating this entry effectively to your team, many of whom might be developing their professional English skills alongside their technical expertise. It’s not just about what you say; it’s about how you say it, ensuring your message is understood precisely and avoids potential misinterpretations.

One common challenge for non-native speakers is the subtle art of framing recommendations. Instead of stating something directly as “we should use this,” which can sound prescriptive and potentially dismissive of existing practices, consider softer approaches. For example, a Slack message proposing a new logging library might read: “I’ve been exploring some newer logging libraries – specifically [Library Name] – that seem to offer improved performance for our current application volume. I’d be interested in discussing the possibility of a small proof-of-concept to evaluate its suitability against our existing solution.” Notice the use of phrases like “I’ve been exploring,” “seem to offer,” and “possibility of a proof-of-concept” – these soften the recommendation and invite collaboration rather than imposing it. Similarly, when describing a feature request in a PR, avoid saying “This will fix X.” Try: “This change addresses the reported issue of [specific symptom] by implementing [solution], which aligns with our broader strategy for improving user experience.”

Another area to focus on is using precise technical vocabulary consistently. While it’s tempting to translate directly from your native language, this can lead to confusion and ambiguity. Ensure you’re utilizing established English terms for concepts like “scalability,” “throughput,” or “dependency injection.” Furthermore, be mindful of the level of detail required – avoid jargon that might not be universally understood within your team. If a term is critical, briefly define it (e.g., “Scalability, in this context, refers to our ability to handle increasing user traffic without performance degradation.”).

Finally, remember the importance of acknowledging potential concerns. A brief statement like, “We should carefully assess the learning curve associated with adopting [Tool Name]” demonstrates foresight and proactively addresses a common hesitation. It shows you’ve considered the practical implications beyond just the technical benefits. Building this level of nuance into your communication will not only improve understanding but also foster trust and collaboration within your team.
