Läpikäynti

Läpikäynti is a Finnish noun used to describe the act of going through something, often translated as a walk-through or review. The term appears in everyday language as well as professional contexts to denote inspecting or validating something by moving through its components, steps, or parts.

In software development and systems engineering, läpikäynti refers to an informal, collaborative review method in which participants step through a design, specification, or code to understand it, surface issues, and discuss possible improvements. It emphasizes shared understanding and early feedback rather than formal defect counting, differing from dedicated inspections or audits.

In project management, architecture, and manufacturing, the term is used for walkthroughs of processes, requirements, blueprints, or production steps, typically involving stakeholders or team members to verify that the material is correct and complete.

Etymology: the word combines läpi (through) and käynti (going, visit). Variants and related terms in Finnish include katselmointi (inspection), tarkastus (inspection), and in English-language texts, walk-through.

The concept is oriented toward communication and mutual comprehension, and its exact meaning can vary by field, but it generally represents a guided, step-by-step review or demonstration aimed at verification and improvement rather than formal testing.
