IMPQI256 – Apply statistical process control (SPC) procedures to support improvement in food operations

Overview 

This standard is about the skills and knowledge needed to apply statistical process control (SPC) procedures as part of your organisation's drive to increase the effectiveness and productivity of food operations. It is a method of quality control which uses statistical methods to monitor, control and improve a process. This is important in the achievement of excellence and the success of manufacture, processing and supply across the food supply chain.

You will need to apply and understand the principles and practices of statistical process control within improvement projects. You will need to show and know how to report and recommend improvements to relevant people within the organisation, including management colleagues. You will need to know how to comply with your company policy for improvement, take responsibility for your actions, and refer any issues outside of the limit of your authority to others.

This standard is for you if you work in food or drink operations including, manufacturing, processing, packing or supply chain activities. You may be a process development technologist or have responsibilities for aspects of organisational improvement in a team leadership or management role.

  4. communicate the purpose of the controls to the relevant personnel

Apply statistical process control to support improvement activity

  1. use approved methodology to monitor and control, and collect performance data on process activities in accordance with the improvement plan
  2. analyse and evaluate performance data in accordance with the improvement plan

Report improvement opportunities
