Commissioning Standard Work

Commissioning Standard Work is essential to provide a structured guide leading the commissioning team through the activities, ensuring all requirements are met and the final product operates as anticipated. The three primary phases of the commissioning process are outlined below: Commissioning itself, Qualification, and Confirmation. Each stage significantly contributes to achieving the project’s final objectives.


In this stage, the equipment management falls on the project team in charge of starting operations, which may also involve suppliers. The operations team observes and provides clarifications on any questions that arise. During this phase, the technical capacity of the facility is validated. Some key activities to be performed include:

  • Executing the Commissioning Plan: Carrying out the actions outlined in the preparation phase.
  • Training: Completing the training as planned earlier.
  • Short-Term Testing: Performing initial tests over brief operational periods.
  • Quality Specification Checks: Verifying that quality assurance specifications are met at nominal speed.
  • Scrap Rate Management: Monitoring and controlling scrap rates to ensure they align with set targets.
  • Defect Identification and Analysis: Identifying and investigating the causes of any defects that emerge during the process.


In the qualification phase, the equipment is operated by the project team in charge of initiating operations without suppliers. The operations team continues to observe the operation, and the line/process and its output are validated. The main tasks to be performed include:

  • Carrying Out the Qualification Plan: Executing the commissioning plan designed for the qualification phase.
  • Extended Production Runs: Running longer production periods (up to eight hours) to confirm operational stability.
  • Verifying Compliance with Quality Specifications: Ensuring adherence to quality assurance standards at specified speeds.
