Developing quality control processes allows your business to operate without you interference , making it easier to expand into new business vision ,
Control Quality concepts :
Control Quality concepts :
- check deliverables to make sure it meet requirements and standards
- completed by control quality department ,but project manager could be involved in process
- quality control department report to project manager about quality issue to be fixed
Quality Management in real world
Quality Management in real world
- customers determine their requirements
- the project team clarify those requirements
- project team determine work will be DONE to meet customer requirements
- project team develop schedule and cost baseline as well as scope baseline
- project manager determine existing standards , policy , plan , and procedures , that maybe available for project
- project manager could create other standards and processes may needed
- quality become one of knowledge areas that project manager must integrate
- the team undertake project execution , to perform activities in scope statement
- the quality control department measure performance of the project by looking at deliverables
- quality assurance department : QA audit project periodically as part of executing process , to see if there is any indication that standards or policies or plan have NOT been met .
- QA department look for best practice that can be used at organization
- QA department look to improve processes being used at organization
- change request will be issued including notification of area need one of (preventive action , corrective action , defect repair )
- to approve change request , we will go through integrated change control process (ICC )
- team adjust work and plan of desired area until DONE
- verified deliverables are move to other control process to gain acceptance
- lesson learned are shared to other project manager and other projects in organization
- later the result : the delivery is accepted , project is completed , quality target are reached , the customer eventually is happy
- the organization has improved process

Quality Control Inputs
Quality Control Inputs :
Project Management Plan
- In particular, the Quality Management Plan, the output of process 8.1 Plan Quality, describes how quality control will be performed within the project.
Quality Metrics
- Describes the attributes to be measured, how they will be measured, and the allowable variations. This is an output of process 8.1 Plan Quality.
Quality Checklists
- Structured lists that help verify that the work and deliverables fulfill the requirements. These are an output of process 8.1 Plan Quality.
Work Performance Data
- Planned vs. actual cost performance
- Planned vs. actual schedule performance
- These are an output of process 4.3 Direct and Manage Project Work.
Approved Change Requests
- These are outputs of the Perform Integrated Change Control process.
Deliverables
- These are an output of process 4.3 Direct and Manage Project Work.
Product Documents
- Quality audit reports and change logs supported with corrective action plans
- Process documentation obtained using the seven basic quality tools of process 8.1 or the quality management and control tools of process 8.2
OPAs
- Organization’s quality standards and policies
- Issue and defect reporting procedures
Quality Control Techniques
Seven basic quality tools
- We have explained seven tools in previous article of plan quality
Statistical sampling

Inspection
- Examination of the work product to see if conforms to standards.
Approved change requests review
- The change requests should be checked to see if the approved changes have been implemented in a timely manner
Quality Control outputs
Quality control measurements
- Documented results of control quality activities..
Validated changes
- Changed or repaired items are accepted or rejected by the customer.
Verified deliverables
- Determines whether deliverables meet the quality standards.
Work performance information
- Results from analyzing work performance data to determine such things as: causes of rejections, or the need for process adjustments
Change requests
- All requests for changes that result from an audit are then input into process 4.5 Perform Integrated Change Control under Integration Management.
Project management plan updates
The following component plans are updated:
- Quality management plan
- Process improvement plan
Project documents updates
- Quality standards
- Quality audit reports
- Process documentation
OPAs updates
