1. 1- DATA GATHERING  

Data-gathering techniques that can be used for this process include but are not limited to:  

  • * Checklists.

  •  Checklists help in managing the control quality activities in a structured manner.  

  • * Check sheets.

  •  Check sheets are also known as tally sheets and are used to organize

  • facts in a manner that will facilitate the effective collection of useful data about a

  • potential quality problem.  

  • * Statistical sampling. 

  • Statistical sampling involves choosing part of a population of

  • interest for inspection. Sample frequency and sizes should be determined during the

  • Plan Quality Management process.  

  • * Questionnaires and Surveys.

  •  Surveys may be used to gather data about customer

  • satisfaction after the deployment of the product or service.  

  1. 2- DATA ANALYSIS  

Data analysis techniques that can be used for this process include but are not limited to:  

  • * Performance reviews.

  •  Performance reviews measure, compare, and analyze the

  • quality metrics defined by the Plan Quality Management process against the actual results.  

  • * Root cause analysis (RCA).

  •  Root cause analysis is used to identify the source of defects.  

  1. 3- INSPECTION  

An inspection is the examination of a work product to determine if it conforms to documented standards.  

  1. 4- TESTING/PRODUCT EVALUATIONS  

Testing is an organized and constructed investigation conducted to provide objective

information about the quality of the product or service under test in accordance with the

project requirements.  

  1. 5- DATA REPRESENTATION  

Data representation techniques that can be used for this process include but are not limited to:  

  • * Cause-and-effect diagrams.

  •  Cause-and-effect diagrams are used to identify the possible effects of quality defects and errors.  

  • * Control charts.

  •  Control charts are used to determine whether or not a process is stable or has predictable performance.  

  • * Histograms.

  •  Histograms can demonstrate the number of defects by source or by component.  

  • * Scatter diagrams.

  •  Scatter diagrams can show the planned performance on one axis and the actual performance on the second axis.  

  1. 6- MEETINGS  

The following meetings may be used as part of the Control Quality process:  

  • * Approved change requests review.

  •  All approved change requests should be reviewed to verify that they were implemented as approved.  

  • * Retrospectives/lesson learned.

  •  A meeting held by a project team to discuss:  

  • * Successful elements in the project/phase,  

  • * What could be improved,  

  • * What to incorporate in the ongoing project and what in future projects, and  

  • * What to add to the organization process assests.
