How to turn data into quality decisions
You cannot improve what you do not measure – proper measurement is the basis for all real and sustained quality improvement.
One of the most well-known statements in management is: "You cannot improve what you do not measure."
Many organizations invest significant time and resources in process improvement, but often they do not measure the right things. The result is decision-making based on gut feeling instead of data.
An advanced quality system relies on consistent, reliable, and relevant measurement. Only when the organization knows what is actually happening can it identify trends, understand deviations, and lead to real improvement.
Measurement enables:
When data is collected consistently and analyzed correctly, it becomes a significant management tool.
Every organization has metrics relevant to its activities, but there are several common metrics:
The most important thing is to choose metrics that reflect the organization’s goals and not just what is easy to measure.
Not every KPI is a good KPI. For example, measuring the number of tests performed does not necessarily indicate the quality of the process.
In contrast, measuring the rate of deviations, the number of corrective actions, or trends in customer satisfaction can provide far more valuable information.
The goal is not to produce more reports, but to make better decisions.
In a machining factory, only the number of products rejected at final inspection was measured for years. After a reevaluation, it was decided to measure also:
Within a few months, it became clear that most rejections were due to one machine that needed recalibration. Without the additional metrics, the problem would have continued to exist.
A good system should be:
Many organizations collect vast amounts of data but do not utilize it. The data is stored in reports, information systems, or presentations, but it does not lead to process change.
Measurement without action does not create value.
Data is a tool, not a goal. When the right things are measured, analyzed, and improvement actions are applied, it is possible to turn information into quality decisions and build a culture of continuous improvement.
At ALD Advanced Solutions, we assist organizations in defining quality metrics, building management dashboards, and implementing advanced measurement methods within quality, reliability, and RAMS projects.
