What is the difference between - Quality Checklist (Output of Plan quality management) and Quality control measurement (Output of Control Quality & Input of Perform Quality Assurance) ?
Checklists and measurements are both sort of parameters to check and validate. Saving Changes...
Checklists are a tool to record measurements. There are other tools to record measurements apart from checklists. Quality control measurements are produced during the quality activity process. So checklists always contain measurements (or data), but measurements don't always require, and are not always used in conjunction with, a checklist.

Hi Sante,
"Quality control measurements are produced during the quality activity process" - does we mean Control Quality Process ? As these measurements are again used as input for Perform Quality assurance.

Hi Navdeep, most quality activities, whether its quality control or quality assurance, will produce quality measurements and data. Your original question asked what is the difference between a quality checklist and quality control measurements. A checklist (created in Plan Quality Management) is just a template or document that will record pre-defined data ranges, process sets or control measurements etc, by checking them off. You could use other tools such as control charts, flowcharts, scatter diagrams, ishikawa diagrams etc. Remember a checklist can also be used as a T&T of Plan Quality Management (PMBOK, p.237), it's not only an output. Further, "Quality control measurements are the results of quality control activities" (PMBOK, p.244), so maybe another way to look at the difference between them is that one is a document and the other is data. The quality control measurements (data) should be "captured in the format that was specified (ie. checklist, scatter diagram, ishikawa) through the Plan Quality Management process" (PMBOK, p.252).

You have two activities: quality assurance and quality control. Quality assurance is performed on process so the main tool is quality checklist to perform quality audit which is the basement of verification activities. Quality control is performed when the product was delivered from the line. So, the only thing you can do is gettting measurements about the product is confirming the requirements by performing validation activities. Then, checklist is a tool used in quality assurance to perform verification activities.

I agree with Mr. Vergini and Mr. Conte. Quality Assurance is focusing on preventing defects. It is process oriented. It ensures that the approaches, techniques, methods and processes are implemented correctly. It makes sure that you are doing the right things, the right way. The checklist is one of the tools used in conducting Quality Assurance.
Quality Control is focusing on identifying the defect. It is product oriented. Testing for quality isn't assuring quality, it's controlling it. There are tools for quality control measurements.
