How to make a control plan

The first task to perform is to analyze the process. We are going to build a process flow diagram (PFD), to characterize the process correctly. It is necessary to determine where there may be problems and sources of variability. For that, it is necessary to know and, above all, to express on a diagram, the work process.

Look at the following web for obtain the recipe:

Download the PFD template and work on it. The template is in PDF format so you can work on it by hand. In it, draw the flow diagram of the process, determining the current identification method that you would use on the different sources of variability. In the Pictures section, include a sketch of the activity that you are describing at all times.

What is a control plan?

Objective: The objective of the following sessions is to develop and apply the concept of quality assurance through learning the appropriate tools: PFD, FMEA, Control Plan, PDCA (although it is related to continuous improvement, it is applicable to all management processes quality).


The material available for this activity is the same in the online version as the face-to-face one. This is because it is an individual realization, although group work gives greater depth to the development of the activity.

The control plans are technical quality documents that are carried out at the project, process or company level to achieve quality assurance, both of the own processes, and that of the suppliers, if so desired. The aim is to tackle the problems derived from the lack of control, anticipating the problems that may arise (as described by the FMEA, and which it is not capable of eliminating) by proposing work plans, monitoring and documentation to carry out the containment action and continuous improvement.

Carrying out the control plans is a multidisciplinary activity, carried out at a transversal level in the company, where all the affected departments are involved. The basic attitude in the generation of the control plans must be constructivist, so that before any approach of deviation on the control, the reaction must be positive and to improve in favor of quality.
