Monitoring, Measurement and Analysis Under ISO 9001
ISO 9001 Clause 9.1
This clause requires the organisation to determine its requirements for monitoring and measurement, so that it can evaluate the quality management system.
What Does ISO 9001 Clause 9.1 Require?
Clause 9.1 of ISO 9001:2015 has three sub-clauses covering the general monitoring and measurement requirements, customer satisfaction, and analysis and evaluation of data.
Clause 9.1.1 - General Monitoring and Measurement
The organisation must determine what needs to be monitored and measured, the methods to be used, when monitoring and measurement will be performed, and when the results will be analysed and evaluated. The performance and effectiveness of the QMS must be evaluated, and documented information must be retained as evidence.
In practice, this means identifying the key performance indicators and data points that give a meaningful picture of QMS performance - customer feedback scores, complaint rates, on-time delivery performance, internal audit findings, nonconformance trends, objective achievement, supplier performance. The organisation determines which of these are relevant and how they are tracked and reviewed.
Clause 9.1.2 - Customer Satisfaction
The organisation must monitor customer perceptions of the degree to which their needs and expectations have been fulfilled. The methods for obtaining, monitoring and reviewing this information must be defined. Customer satisfaction monitoring is one of the key measures of QMS effectiveness and feeds directly into the management review inputs under Clause 9.3.
Methods for gathering customer satisfaction data include satisfaction surveys, post-delivery feedback requests, analysis of complaints and compliments, customer retention rates, repeat business, and direct customer feedback collected during account management or project reviews. The method should be appropriate to the size and nature of the organisation and its customer base.
Clause 9.1.3 - Analysis and Evaluation
The organisation must analyse and evaluate data and information arising from monitoring and measurement. The results of this analysis must be used to evaluate conformity of products and services, customer satisfaction levels, QMS performance and effectiveness, planning effectiveness, risk and opportunity actions, external provider performance, and the need for improvements. The outputs of this analysis are key inputs into the management review.
For Clause 9.1, I'm looking for evidence that the organisation is actively monitoring meaningful performance data and using it to drive decisions. I'll check that customer satisfaction is being monitored through some systematic method - not just informally. I'll look at what data is being collected, how it is being analysed, and whether the results are feeding into management review and improvement decisions. An organisation that collects customer satisfaction data but never looks at it, or one where the data always shows 100% satisfaction regardless of what is happening operationally, raises questions I'll want to explore further.
Customer satisfaction monitoring is the sub-clause that organisations most commonly under-develop. A simple, consistent approach - a short feedback survey sent after every delivery or project completion, reviewed quarterly - provides meaningful data without significant overhead. What matters is that the method is systematic, the results are analysed, and any trends or issues are actioned. Ad hoc feedback collected informally but never analysed does not satisfy the requirement.
Work out what you need to measure to know whether your QMS is doing its job - customer satisfaction, complaint rates, quality objectives progress, audit findings - track those things consistently, and review the data at your management review. The IMS1 Manual includes a monitoring and measurement section that provides a structure for this. For customer satisfaction, a simple feedback form sent after jobs are completed is sufficient for most organisations. Collect it, look at it, act on any issues. That is what this clause needs.
Practical Compliance Guidance
To comply with Clause 9.1, the organisation needs defined monitoring and measurement arrangements, a systematic approach to collecting customer satisfaction data, and a process for analysing the results and using them to inform decisions about QMS performance.
