A software walkthrough (also written as walk‑through) is a form of software peer review in which the author or designer of a software product leads members of the development team and other interested parties through the product, soliciting questions, comments, and feedback. The “software product” typically refers to technical documentation such as design specifications, source code, use‑case descriptions, business process definitions, test‑case specifications, or other artifacts related to a software system.
The primary objectives of a walkthrough are to obtain feedback on the technical quality or content of the material and to familiarize participants with that material. Unlike formal technical reviews or inspections, a walkthrough is generally less structured, focuses on education and early detection of potential defects, and does not require the strict adherence to defect‑identification procedures mandated by inspections. It may be informal or may follow the process outlined in IEEE Standard 1028 for software reviews.
Typical participants and roles
- Author – presents the product step‑by‑step, often responsible for addressing identified issues.
- Walkthrough leader – facilitates the session, handles administrative tasks, and ensures orderly conduct; this role is frequently filled by the author.
- Recorder – documents anomalies, decisions, and action items identified during the session.
Participants may include developers, testers, quality‑assurance staff, subject‑matter experts, or other stakeholders who have a technical interest in the product.
Relation to other review types
- Technical review – more formal, with defined procedures and often focused on evaluating adherence to standards.
- Inspection – a highly structured, defect‑oriented review that emphasizes defect detection and may include formal metrics.
- Walkthrough – emphasizes knowledge transfer and early feedback; it may suggest direct alterations but does not concentrate on formal measurement or process improvement.
Walkthroughs can be mandated by organizational norms or standards, and they are commonly used early in the development lifecycle to catch problems before more formal reviews.
