I have some asking for my clear understanding on Root cause analysis as well as CAR form.
What is the process?
What are the procedures?
What is the technical errors?
What is non-technical errors?
Which subjects will be considered as a training problem.
What is the difference between process and procedures?
What is immediate action?
What is corrective action?
Do you have any best guidelines that will help me to be an expert on CAR- PAR.
To answer your question, I will address your overall question of how to effectively implement corrective actions, which incorporates the step of root cause identification.
To address corrective action effectively, you will start with a documented procedure which specifies which events are considered to be deviating (nonconforming), as well as the processes (sequence of steps) that the laboratory must take when complaints are received, nonconforming work is identified, and corrective actions are required. This procedure will apply to all laboratory activities that may be the subject of complaints or nonconformities and will, therefore, cover technical and non-technical deviations from the planned objectives of the laboratory. The assigned responsible person must decide, after initial investigation, if a containment (immediate) action is required; based on the impact or seriousness of the complaints or nonconformity.
A Corrective Action form must be used to capture all incidents, complaints and nonconformities to ensure the correct personnel are informed and the root causes of problems are identified. Getting to the root cause could involve a number of techniques, where the laboratory will select suitable tools from those listed in the procedure, for the specific type of event. Either way, it is essential to clearly state the problem in order to get to the root cause and thereafter select the appropriate action that will correct the issue and prevent it from reoccurring.
These articles will provide further guidance. Written for ISO 9001, they are also applicable to ISO 17025:
