PROCEDURE

  • Complaint Receipt
    • The complaint shall be acknowledged within a working day by mail to initiate the process.
    • Customer complaints are first registered by the QA department.
    • QA initiates the complaint investigation process by registration of the subject complaint and assigns a unique Customer Complaint Number, e.g. "SIPLQAYY001" ("YY" is the year).
    • Thorough investigation of the customer complaint starts once the quality complaint is registered. Response time is tracked after the formal registration of the complaint.
    • All the complaints are routed through the structured problem-solving methodology.
    • A time-bound action-plan report shall be made and submitted to the customer if required.
  • Categorisation of Complaints

      • Critical – when the complaint is related to legal or product safety matters.
      • Major – all quality-related complaints.
      • Minor – all others.
  • Action Plan
    • The QA Head will take immediate containment action on the complaint, and also initiate a detailed investigation of the complaint with the concerned personnel and prepare a time-bound action-plan on the root cause(s). This action-plan report shall be sent to the customer. The QA Head shall also track and monitor corrective action effectiveness and maintain its records as per the Quality Management System.
    • The procedure for handling of market complaints must include, but is not limited to:
      • The receipt and recording of complaints from all sources.
      • Receiving, processing, investigating, documenting and reporting market complaints, and reporting the results of the investigation back to the complainant.
      • Where appropriate, the examination of retained samples of the batch subject to the complaint is performed.
      • The concerned Manufacturing Head shall be actively involved in the complaint investigation and the preparation of the corrective / preventive action-plan on the root cause.
    • The action-plan must be completed as per the complaint categorisation:
      • Critical – first response within 15 days and final closure within 45 days.
      • Major – first response within 30 days and final closure within 45 days.
      • Minor – first response within 45 days.
    • The above timings are counted from plan initiation. However, in some exceptional circumstances, such as dependency on vendor / contractor / government authorities / major civil work, etc., it can be extended by 30 days additionally after review. The customer shall be informed in case of any time extension.
    • A summary (Customer Complaint Log) of market complaints and their trends shall be maintained by QA of the respective production unit for yearly review.
