In working with medical device and biopharma companies, I have gathered common mistakes about CAPA reporting:

• not identifying other systemic issues
• not documenting what was identified as not a contributor after testing each probable contributing causes
• not identifying effectiveness checks
• not monitoring (may use spreadsheet to document meeting minutes,updates ,records,files)
• not all audit results that needs improvements needs to have a CAPA
• not looking at trends from archive data for measurements,KPIs,test results,other quality data
• not segragating and isolating defectives
• no training for those who writes CAPA reports
• no open communication to all parties and outside customers involved in the process
• inadequate plan or forms, to document trace to complaints and other sources of deviations/variations/customer dissatisfaction
