laatukäyrä

A laatukäyrä, a Finnish term translating to "quality curve," is a graphical representation used to visualize and analyze the quality of a product or service over time. It typically plots a measure of quality on the vertical axis against time on the horizontal axis. The specific quality metric can vary widely depending on the context, ranging from customer satisfaction scores, defect rates, performance indicators, or any other quantifiable aspect of quality.

The purpose of a laatukäyrä is to identify trends, patterns, and potential issues related to quality. By observing the shape and movement of the curve, stakeholders can understand if quality is improving, deteriorating, or remaining stable. For instance, a downward trend might signal an emerging problem that requires investigation and corrective action, while an upward trend could indicate the success of quality improvement initiatives.

Laatukäyrät are valuable tools in quality management systems. They facilitate data-driven decision-making and provide a clear, visual summary of quality performance. They can be used in various industries, from manufacturing and software development to customer service and healthcare. When interpreting a laatukäyrä, it is important to consider the time scale, the chosen quality metric, and any external factors that might have influenced the quality levels during the observed period.
