Fertigstellung

Fertigstellung is a German term used to describe the completion of all work required to render a project or product ready for use, handover, or operation. The word derives from fertigen, meaning to finish or make ready, and stellen, to place or set. In project management and construction, Fertigstellung marks a transition from execution to realization, often accompanied by formal verification and acceptance.

In construction and manufacturing, Fertigstellung is commonly linked to a formal handover process. It is distinct from the later steps of operation and maintenance, such as commissioning (Inbetriebnahme) and acceptance (Abnahme). The degree of completion, or Fertigstellungsgrad, is frequently used to report progress and determine when a project may be handed over to the client. Partial completions, known as Teilfertigstellung, are possible and may trigger staged handovers.

The process leading to Fertigstellung typically includes final inspections, defect rectification, compliance checks with codes and standards, and the compilation of final documentation such as as-built drawings, operation manuals, and guarantees. After handover, the liability for defects and the start of the warranty period are usually defined by contract and applicable law, influencing subsequent maintenance and remedies.

In software and product development, Fertigstellung can refer to a state of being feature-complete or meeting a defined "Definition of Done." While this signals readiness for release, it does not exclude post-release maintenance, updates, or ongoing quality assurance.
