Brittle and risky can both flag a problem, but they answer different questions. A "brittle system" may fail after a small change or at one weak point. A "risky choice" exposes someone or something to possible harm or loss. Name the facts before you choose either word.
Quick check: broad danger or narrow tolerance?
Use the adoption threshold, not the seriousness of the decision, to choose the more precise word.

Learn "Brittle" in depth →The test: can you name the exact dependency?
"Risky" describes exposure to a bad outcome. Its cause may be known or unknown. "Brittle" describes poor ability to handle stress or change. A named weak point makes the second claim more useful, but the word does not require one exact cause.
"The release process is risky because only Maya knows how to recover a failed deployment" can become "The release process is brittle because recovery depends on one person's deployment knowledge" -- if tests or past events support that claim.
"The forecast is risky because demand is hard to predict" describes uncertainty. "The plan is brittle because it fails below a 40% adoption rate" names a weak limit.
The first example concerns the chance of a bad result. The second concerns how much change the plan can bear. A plan can be both "risky" and "brittle" at the same time.

Start the "Brittle" learning path →The common mistake: settling for the vaguer word
Do not replace every use of "risky" with "brittle." A risk may come from price shifts, law, demand, safety, or several causes at once. A "risky claim" becomes more precise with evidence, such as a range, probability, prior data, or defined scenario. A "brittle claim" needs evidence about limited tolerance or a weak point.
Before you write either word, ask what you know. If the issue is low tolerance for change, "brittle" may fit; name the weak point and a way to add capacity, a backup, or margin. If the issue is possible harm or loss, "risky" may fit; name the outcome, evidence, decision owner, and choice that must be made.
Practice scenarios
Practice using brittle in situations like:
- separating "risk exposure" from "low tolerance" for stress or change
- supporting a brittle claim with evidence about a weak point, limit, or lack of backup
- supporting a risky claim with evidence, the possible harm, and the decision it affects
Useful practice phrases:
- "[X] is risky because [possible harm]." -> "[X] is brittle because [evidence of low tolerance]."
- "Risky" asks what bad outcome is possible; "brittle" asks what stress the subject can bear.
- "A plan can be both risky and brittle; name evidence for each claim."
Keep Juniper's unknown market broadly risky
"Risky" describes exposure, while "brittle" describes low tolerance for stress or change.
Evidence helps a team use either claim when making a decision.
