# Jumped the Gun? Meaning + the Mistake Everyone Makes > To do something too soon, especially without thinking carefully about it. - **Term:** jump the gun - **Part of speech:** idiom (verb phrase) - **Pronunciation:** /ˌdʒʌmp ðə ˈɡʌn/ - **English level (CEFR):** B1–B2 - **Register:** Casual, Spoken - **Region:** US and UK - **Topic:** [Business jargon](https://app.speaktechenglish.com/learn/topics/business-jargon.md) - **Lesson:** https://app.speaktechenglish.com/learn/jump-the-gun - **Last updated:** 2026-10-27 ## Meaning To do something too soon, especially without thinking carefully about it. In software engineering, jumping the gun refers to moving forward with decisions or actions before you have sufficient information or approval. This commonly happens during standups when a developer might say they're deploying code that hasn't passed code review, or in planning meetings when someone starts implementation before requirements are finalized. You'll also hear it in retrospectives discussing what went wrong during an incident, or in interviews when candidates describe past projects. The phrase emphasizes impatience or incomplete preparation rather than actual speed. A typical workplace example: "We jumped the gun by deploying to production Tuesday without waiting for QA sign-off." A common learner mistake is using this phrase to simply mean working quickly—the idiom specifically implies acting prematurely or without proper groundwork, not just working fast. The underlying concern is usually risk: rushing creates bugs, misalignments, and rework. ## When you hear it Common in standups, retrospectives, and planning meetings. Less common in formal documentation. ## Examples - **Standup:** "I might be jumping the gun, but I started on the API changes before the design review." - **Slack message:** "Did we jump the gun announcing the feature? The backend isn't ready yet." - **GitHub PR:** "Closing this PR — we jumped the gun and need to wait for the new requirements." - **Jira ticket:** "Moved back to backlog. We jumped the gun on this before getting stakeholder approval." - **Retrospective:** "We jumped the gun on the launch and had to roll back. Let's add a release checklist next time." - **Sprint planning:** "Let's not jump the gun — we need the PM to confirm scope before we commit to this." - **Pair programming:** "Wait, are we jumping the gun? Should we check the acceptance criteria first?" ## What native speakers say - "Let's not jump the gun — we should wait for the spec to be finalized." - "I think we jumped the gun on that release." - "Maybe I'm jumping the gun here, but should we start the migration now?" - "Don't jump the gun — let QA finish their testing first." - "We kind of jumped the gun announcing that feature." ## Common mistakes - ✗ "We jumped gun on the release." → ✓ "We jumped the gun on the release." (Always include 'the' — it's 'jump the gun', not 'jump gun'.) - ✗ "I jumped the gun the feature." → ✓ "I jumped the gun on the feature." (Use 'on' to connect to what you did too early.) - ✗ "He is jumping the gun yesterday." → ✓ "He jumped the gun yesterday." (Match the tense — use past tense for past events.) ## Be careful Saying someone "jumped the gun" can sound like criticism. Use "we" or soften with "might be jumping the gun" when talking about others. ## Word forms | Part of speech | Word | Example | | --- | --- | --- | | base form | jump the gun | Don't jump the gun on the deployment. | | past tense | jumped the gun | They jumped the gun and launched the product before it was fully tested. | | present participle | jumping the gun | I might be jumping the gun, but can we start now? | | gerund | jumping the gun | Jumping the gun caused problems with the release. | ## Collocations - **jump the gun on**: Most common preposition — 'We jumped the gun on the launch.' - **don't jump the gun**: Warning to wait — 'Don't jump the gun, let's get approval first.' - **might be jumping the gun**: Softened version when suggesting something early — 'I might be jumping the gun, but...' - **kind of jumped the gun**: Admits a mistake without being too direct — 'We kind of jumped the gun there.' - **jumped the gun a bit**: Minimizes the mistake — 'I jumped the gun a bit on that PR.' ## Synonyms - **act prematurely**: More formal, used in documentation or postmortems. - **rush into**: Similar meaning but emphasizes speed more than timing. - **get ahead of ourselves**: Team-focused — 'We got ahead of ourselves on that release.' - **move too fast**: More neutral, less idiomatic. ## Opposites - wait for the green light - hold off - take our time - wait for approval - proceed cautiously ## Practice This lesson has 4 practice exercises with instant feedback on the page: https://app.speaktechenglish.com/learn/jump-the-gun ## FAQ ### What does 'jump the gun' mean in a tech team?
