ISO 9001:2015 Clause 9.1.3 Analysis and evaluation

The organization shall analyse and evaluate appropriate data and information arising from monitoring and measurement.
The results of analysis shall be used to evaluate:
a) conformity of products and services;
b) the degree of customer satisfaction;
c) the performance and effectiveness of the quality management system;
d) if planning has been implemented effectively;
e) the effectiveness of actions taken to address risks and opportunities;
f) the performance of external providers;
g) the need for improvements to the quality management system.
NOTE Methods to analyse data can include statistical techniques.

1) The organization shall analyse and evaluate appropriate data and information arising from monitoring and measurement.

Monitoring and measurements established within the organization will generate a lot of data and information. To fully utilize this information, analysis and evaluation of data is required to help the management in decision making. Just gathering and looking at numbers without any analysis and evaluation will just be a futile exercise that will take a lot of effort without any real value derived out of it. Let’s take an example to understand this better. If you are just tracking the number of returned pieces of your product and not analysing the trends over a period of time, you cannot improve your products or services to your customers. Benchmarking or setting up goals on the achievement of your objectives is a useful method that can be used to identify any red flags beforehand. If your goal (looking at your previous performance) indicates that you do not have more than 2 returns in a month, but suddenly in a month you get 4 return requests, it is an alarm for you to look into the issue and find out the root causes behind it. This will help you in taking timely action before the issue goes out of control and fetch you some bad reputation. It is, therefore, important that data is analysed, a conclusion drawn out of it, and plans and actions made whenever an unfavourable trend or condition is observed. That is why analysis and evaluation of data is important for any organization. This will help you seize all opportunities of improvement that exist.

Analyzing and evaluating data and information arising from monitoring and measurement is a systematic process that organizations can follow to ensure they make informed decisions and improve their operations. Here is a step-by-step guide on how to analyze and evaluate such data effectively:

  1. Define Objectives and Key Performance Indicators (KPIs): Start by clearly defining your organization’s objectives and the specific KPIs or metrics that align with these objectives. This step ensures that you are collecting data that is relevant to your goals.
  2. Collect Data: Implement data collection methods and systems to gather information related to the identified KPIs. This data may come from various sources, such as customer feedback, production processes, sales records, or website analytics.
  3. Organize and Clean Data: Ensure that the collected data is organized, accurate, and free from errors. This may involve data cleaning and validation processes to eliminate outliers and inconsistencies.
  4. Data Analysis: Use data analysis techniques to uncover patterns, trends, and insights. Depending on the nature of your data, you can employ statistical analysis, data visualization, or machine learning algorithms to extract meaningful information.
  5. Bench-marking: Compare your organization’s performance data against industry benchmarks or historical data to gain context and identify areas that require attention. Bench-marking can provide valuable insights into competitiveness and efficiency.
  6. Evaluate Performance: Assess the performance of your organization based on the analysis results. Determine whether you are meeting your targets and objectives or if there are areas of concern.
  7. Identify Root Causes: If performance is not meeting expectations, investigate the root causes. Use tools like root cause analysis (RCA) to identify underlying issues that need to be addressed.
  8. Make Informed Decisions: Based on the analysis and evaluation, make informed decisions about what actions to take. This may involve initiating corrective actions to address issues or implementing improvement initiatives.
  9. Set Priorities: Not all issues or opportunities for improvement are of equal importance. Prioritize actions based on their potential impact on your organization’s objectives and the resources available.
  10. Document Findings and Actions: Keep thorough records of your data analysis, evaluation results, and the decisions and actions taken. Proper documentation is crucial for accountability and future reference.
  11. Implement Changes: If corrective or improvement actions are required, implement them effectively. Monitor and measure the impact of these changes to ensure they achieve the desired results.
  12. Monitor Continuously: Establish a continuous monitoring and measurement process. Regularly revisit your KPIs, collect data, and repeat the analysis and evaluation cycle to drive ongoing improvement.
  13. Communicate Findings:Share the findings, actions, and results with relevant stakeholders within the organization. Effective communication ensures that everyone is aware of the progress and can contribute to the improvement process.
  14. Feedback Loop: Use the insights gained from your ongoing analysis and evaluation to refine your data collection methods, KPIs, and strategies. Continuously adapt to changing circumstances and opportunities.
  15. Compliance and Reporting: If your organization operates within specific regulatory frameworks or standards, ensure that you comply with reporting requirements related to data analysis and evaluation.

By following these steps and maintaining a systematic approach, organizations can effectively analyze and evaluate data and information arising from monitoring and measurement to drive continuous improvement and achieve their objectives.This clause requires that an organization collects, analyses and evaluates Quality Management System data. Both analysis, as well as evaluation of data, is important; that means data analysis through statistical techniques, trend analysis, etc. and interpretation of the analysed data so that it can be used in an appropriate manner, for example- for decision making and action planning.
