Taasteprosessiin

Taasteprosessiin is a Finnish concept that describes a systematic method for turning production obstacles into optimised workflow improvements. The term combines “taaste,” meaning challenge or test, with “prosessiin,” the in‑case form of process. It was first articulated by industrial engineer Tapio Rissanen in a 1995 conference presentation on lean manufacturing practices in Finland. The idea quickly spread to other Scandinavian industries and is now cited in European manufacturing literature as a form of problem‑driven innovation.

The core of taasteprosessiin comprises four sequential stages. First, identification involves listing all inefficiencies or bottlenecks that hinder throughput. Second, analysis breaks each challenge down into root causes, often applying fault‑tree or Pareto techniques. Third, redesign focuses on creating alternative routing, tooling or scheduling that eliminates the root problem. Fourth, implementation phases the change into the existing production line with minimal disruption, usually under a pilot test before full roll‑out. Documentation and feedback loops are integral to the process, ensuring that lessons learned are institutionalised.

Practitioners in automotive, electronics assembly, and software development have reported significant yield increases and cost reductions by applying taasteprosessiin. In automotive manufacturing, it has helped reduce change‑over times by up to 30 %. In software, the methodology is adapted for continuous integration pipelines, yielding a 15 % improvement in deployment frequency. Critics argue that the process can be time‑consuming for very small or highly dynamic teams, and that it may require cultural change beyond procedural adjustments. Ongoing research explores how digital twins and AI can accelerate the analysis and redesign phases, potentially making taasteprosessiin more scalable for high‑volume, high‑variability production environments.
