Root Cause Investigation for CAPA

Most organizations have procedures for implementing corrective and preventive actions, but many do not have an effective methodology to actually investigate to find the root cause. As a result the investigation is often careless, unsuccessful, and costly. Root Cause Investigation for CAPA is a proven methodology to investigate and identify the root cause when there has been a shift in the performance of a product, machine, equipment, work process, or system. The methodology identifies the change (or changes) that have been occurred so that the change can be eliminated and the performance can return to its previous level. It is ideal for investigating an increase in:

  • Product or service defect levels
  • Customer complains
  • Negative patient reactions with the product
  • Manufacturing scrap or rework
  • Equipment or process aberrations
  • Any performance change where a CAPA investigation is required

In this exciting and team-based seminar you will be challenged to apply the methodology and tools on real case studies. This will prepare you to confidently conduct successful investigations immediately upon returning to work.

Learning Objectives

Upon completion of this course, you will be able to:

  • Apply a seven step investigational methodology to determine the root cause of a technical problem
  • Identify the technical root cause(s) and any systemic root causes(s)
  • Implement effective/preventive actions to restore the original product or process performance
  • Develop and implement a control plan to assure you do not have this issue again

Who Should Attend

This is a highly practical and workshop-oriented course for those in the pharmaceutical or medical device industry who conduct Corrective and Preventive Action (CAPA) investigations, especially those in the following areas:

  • Regulatory Affairs
  • R&D
  • Quality Assurance
  • Maintenance
  • Manufacturing
  • Distribution
  • Product/Process
