The process flow for the Management of Change system has the following steps :



The system can also be configured so that higher risk changes follow a more rigorous path




Concept Approval


The Concept Approval step allows the team to review the intent of a change and agree that it is appropriate to carry out.

Risk Assessment Preparation


The Risk Assessment Preparation Phase contains the following sub sections :

Hazop Requirement Check


The Hazop Requirement Check is a short set of questions which helps to determine if a Hazop is required in addition to the Request for Change.

Hazard Review


The Hazard Review section of the Request for Change has two sections. In the first section the author selects which topics need to be considered. In the second section the author comments on each of these sections to either set out the mitigation required or explain why no mitigation is required.

Records Review


In the Records Review section the author identifies those records which must be updated as a consequence the change. The system automatically creates an action for each of the required records. These actions are issued to the actionees when the Risk assessment is approved.

Risk Classification


One of the key concepts of the system is that the level of rigour required to complete a Request for Change should be proportionate to the level of risk involved. To allow the Request for Change to be routed appropriately it is classified into high, medium or low risk. Including the correct personnel in this Risk Classification step is key.

Risk Assessment Approval


After Risk Assessment Preparation the next step is Risk Assessment Approval. The personnel required for this approval will depend on the Risk Classification. The approvals are defined by role. Each has a named holder and the option of one or more deputies.

Specification Check

The Specification Check provides the opportunity to check if the specification or design that has been carried out since the Risk Assessment Approval was given does not invalidate the Risk Assessment.

Execution


Once the RFC has been approved the change enters the execution phase. There can be one or more Construction Stages and Commissioning Stages.

Construction Stages


Using construction phases allows the construction work to be controlled at a high level. Construction phases are not a replacement for the Permit to Work systems.

Commissioning Stages


The Commissioning Stages control the pre-commissioning checklists, the agreement to start commissioning and the agreement that commissioning is complete.

Review


The Review Stage takes place after the change and all of its associated actions and records have been completed

Actions and Records


Actions can be raised at any point in the change process. Actions are also automatically raised for any records that need to be updated.

The Actions can be Interlocked to each of the stage gates in the process.
