Työvaiheissa

Työvaiheissa is a Finnish term used to describe the organization of work into distinct phases or stages. In a phase-based approach, a process is divided into sequential work phases, each with defined objectives, inputs, outputs, and criteria for moving on to the next phase. The term is common in Finnish discussions of project management, manufacturing, construction, and software development.

In practice, Työvaiheissa supports planning and control by making responsibilities explicit and enabling phase-gate decisions. At the end of each phase, reviews assess whether requirements are met before proceeding. This approach improves traceability, risk management, and quality assurance, as work is measured against phase-specific criteria rather than only final outcomes.

Typical phases include planning, design or specification, implementation or production, verification or testing, deployment or handover, and maintenance or evaluation. Some fields add iteration loops or parallel sub-phases, reflecting agile or iterative methodologies within a broader phase-based framework.

Työvaiheissa is related to concepts such as phase-gate or stage-gate processes, work breakdown structure, process mapping, and quality management systems. While the terminology and detail vary between industries, the core idea remains to structure work so that each phase adds value and provides checkpointing.
