Difference Between Monitoring and Measurement in ISO 9001

Difference Between Monitoring and Measurement in ISO 9001

In ISO 9001, monitoring and measurement are two terms often mistaken for each other. Their similar objectives and interconnected techniques can be highly confusing for businesses dealing with quality management system for the first time.

In this blog, we’ll dive right into the difference between monitoring and measurement in ISO 9001—definitions, objectives, and activities.

But before that, let’s take a detour to clause 9.1.1 of ISO 9001 which explains the concept of monitoring and measurement.

ISO 9001 Clause 9.1.1: A Quick Overview

“Evidence-based Decision Making” is one of the 7 principles of ISO 9001:2015 . It stresses the importance of data-driven insights to make decisions rather than assumptions.

Clause 9.1.1 of the standard puts this principle to the core by covering 4 crucial phases of gathering the evidence—monitoring, measuring, analyzing, and evaluating.

It emphasizes on:

  • What needs to be monitored and measured
  • Monitoring and measuring activities/methods
  • Time and frequency of measurement
  • When and how to analyze and evaluate

The goal is to compare the current results of the QMS processes with the desired results to assess their alignment with the quality objectives set in the beginning.

What Is Monitoring in ISO 9001?

Monitoring refers to the act of observing or surveilling something continuously. This can be an entire system, a process, or a task.

The aim is to determine and document the status of the aspect being monitored for measurement, data analysis, and evaluation .

Objectives of Monitoring:

1. Early Detection of Non-conformities

By constantly monitoring the quality management system, businesses can detect issues and deviations as and when they arise. This leads to quick resolution while promoting a culture of proactive risk management .

2. Focus on Trends

Monitoring helps identify patterns and trends over time as live data is continuously recorded and stored for analysis.

Techniques for Monitoring

1. Statistical Process Control

Through this technique, organizations can monitor the stability of their processes and track variations.

2. Internal Audits

Audits help businesses understand the current situation of their QMS, thus providing a log of essential data for evaluation.

3. Data Collection

There are numerous data collection techniques through which businesses can monitor the QMS. These include recording data from feedback mechanisms, tracking key performance metrics (KPIs) , etc.

What Is Measurement in ISO 9001?

Measurement is a quantitative process that compares the QMS data with the quality objectives or set parameters. This is where businesses can catch deviations and non-conformities specifically.


1. Quantify QMS Performance

The essence of measurement in ISO 9001 lies in quantifying the performance of the QMS to evaluate its effectiveness. This aids in providing concrete data for analysis and decision-making.

2. Benchmarking

Businesses can verify alignment with compliance standards, regulations, and quality processes by comparing the performance metrics data with the ideal parameters.

Techniques for Monitoring:

1. Testing

Controlling inspections and testing gives an insight into the functionality of a product and compliance.

2. Dimensional Measurement

Employees can physically check the products against the dimensional specifications set by the business using various tools, instruments, and equipment.

3. Process Capability Analysis

This technique is useful for determining the capability of a process to produce products that are in accordance with the set parameters.

Monitoring vs. Measurement: Key Differences

Let’s take a quick look over the key differences between monitoring and measurement in ISO 9001 :

1. Purpose

Monitoring can be a qualitative as well as a quantitative process. Measurement, on the other hand, is strictly quantitative.

While the former aims to primarily gather all the data of the QMS for further usage, the latter acts on the data to draw a comparison between the current and the desired outcomes.

2. Tools & Techniques

Following its purpose, monitoring relies on data collection techniques like observations, checklists, questionnaires, feedback mechanisms , audits, etc.

Measurement adopts methods like checking the dimensions of a product, controlled testing, and process capability analysis to obtain precise data.

3. Frequency

One major difference between monitoring and measurement is that the former occurs continuously. Of course, there are exceptions. For example, audit procedures help monitor QMS processes, but they do not take place every second.

Measurement is done at intervals. It might be regularly scheduled or based on certain events that call for measuring the data.
