In tech, it usually means reviewing code, a process, or a feature with someone to ensure understanding or identify issues. A walk-through is a structured way to go through something methodically, often in a meeting or review session. In software development, walk-throughs are commonly used during code reviews, when onboarding new team members, or before launching a feature. The person conducting the walk-through explains each step, shows what happens at each stage, and invites questions or feedback. It is different from a training session because walk-throughs are usually more focused on a specific piece of work, and different from a presentation because walk-throughs are more interactive and detailed. Walk-throughs help teams catch bugs early, ensure code quality, and make sure everyone understands the design and implementation. ## When you hear it Our QA team asked for a walk-through of the new payment flow before testing it. ## Examples - **in a code review meeting:** "Before we merge this, I want to do a walk-through of the database schema changes with the team." - **in a standup:** "Yesterday I completed a walk-through of the new API endpoints with the frontend developers." - **in onboarding:** "On your first day, the tech lead will give you a walk-through of our development workflow." ## What native speakers say - "Let's do a quick walk-through of the code changes." - "Can you walk us through the deployment process?" - "I will give you a walk-through of how the authentication works." ## Common mistakes - ✗ "We need to do a walk through of this feature." → ✓ "We need to do a walk-through of this feature." (Walk-through must be hyphenated when used as a noun.) - ✗ "I will walk-through you the system architecture." → ✓ "I will walk you through the system architecture." (When used as a verb phrase, it is walk through (two words). The hyphenated form is only a noun.) - ✗ "Can you provide a walk-through on how to use Python?" → ✓ "Can you provide a walk-through of how to use Python?" (Use of instead of on when describing what the walk-through covers.) ## Be careful Often confused with walk through (two words, meaning to physically move through something). The hyphenated walk-through is a noun referring to a guided explanation or demonstration. ## Word forms | Part of speech | Word | Example | | --- | --- | --- | | noun | walk-through | The architect gave a walk-through of the system design. | | verb phrase | walk through | Let me walk you through the deployment steps. | ## Collocations - **give a walk-through**: To provide or conduct a walk-through for someone. - **do a walk-through**: To perform or conduct a walk-through as a group activity. - **quick walk-through**: A brief, faster version of a walk-through covering the main points. - **code walk-through**: A walk-through specifically focused on reviewing source code. - **security walk-through**: A detailed review of security measures or vulnerabilities. ## Synonyms - **walkthrough**: Same meaning but written as one word (less common in modern tech English). - **code review**: Similar process but walk-through is broader and can apply to any process or feature. - **demo**: Similar in showing how something works, but demo is usually more formal and polished; walk-through is more detailed and educational. - **tutorial**: Similar in teaching aspect, but tutorial is usually a recorded or written guide; walk-through is interactive and live. ## Opposites - black box (understanding nothing about the process) - abstraction (hiding implementation details) ## Practice This lesson has 4 practice exercises with instant feedback on the page: https://app.speaktechenglish.com/learn/walk-through ## FAQ ### What is the difference between a walk-through and a code review? A code review is specifically about examining source code for quality and bugs. A walk-through is broader and can apply to any process, feature, or system. Walk-throughs are also typically more educational and interactive, explaining the why behind decisions, not just the what. ### How long does a walk-through typically take? It depends on the complexity of what is being reviewed. A quick walk-through of a simple feature might take 15-30 minutes. A thorough walk-through of a complex system could take 1-2 hours or more. It is common to break longer walk-throughs into multiple sessions. ### Is walk-through formal or informal? Walk-through is neutral in formality. It is used in both casual team discussions and formal review meetings. It is a professional term but not overly formal. ### Do I need to prepare for a walk-through? Yes, it is good practice to prepare. If you are conducting the walk-through, organize your thoughts and materials in advance. If you are attending, read any relevant documentation beforehand to ask informed questions. ### Can walk-through be used as a verb? Not with a hyphen. The verb phrase is walk through (two words), as in walk me through the process. The hyphenated walk-through is only a noun. ## Related - [code review](https://app.speaktechenglish.com/learn/code-review.md) - [standup](https://app.speaktechenglish.com/learn/standup.md) - [documentation](https://app.speaktechenglish.com/learn/documentation.md) - Full glossary: https://app.speaktechenglish.com/learn.md - Live lessons with a coach: https://app.mocklyenglish.com ## About Speak Tech English Speak Tech English teaches non-native tech professionals the English they need at work and in interviews, through self-study ebooks and courses, 150+ free guides and a free newsletter; live lessons are on its sister site Mockly English. - Shop: https://speaktechenglish.com/courses/ - All products (markdown): https://speaktechenglish.com/products.md - Free guides (markdown): https://app.speaktechenglish.com/guides.md - Tech English glossary (markdown): https://app.speaktechenglish.com/learn.md - Newsletter (10% off): https://speaktechenglish.com/#subscribe - Live lessons and mock interviews: https://app.mocklyenglish.com ## Notes for agents - Speak Tech English sells self-study material.
