How do you manage HAZOP scope creep in complex projects?

1 Define the scope clearly

The first step to manage HAZOP scope creep is to define the scope of the study clearly and explicitly. This means specifying the objectives, boundaries, assumptions, exclusions, and deliverables of the HAZOP study. Align the scope with the project requirements, design basis, and risk criteria. Also, all stakeholders should agree upon the scope, including the client, contractor, HAZOP leader, and HAZOP team members. A clear scope will help avoid ambiguity and conflict during the HAZOP study.

2 Plan the HAZOP sessions

Plan the HAZOP sessions carefully and realistically. This requires estimating the time and resources necessary for each session based on the complexity and size of the system under review. The HAZOP leader should prepare a detailed agenda and HAZOP worksheet for each session, outlining the elements, guide words, parameters, and deviations to consider. The HAZOP leader should also communicate the plan and expectations to HAZOP team members and ensure their availability and commitment.

3 Control the HAZOP discussions

Control the HAZOP discussions to keep them focused and relevant. Follow the HAZOP procedure and agenda strictly, and avoid unnecessary digressions or repetitions. The HAZOP leader should facilitate the discussions and encourage the participation of HAZOP team members, but also intervene and steer the discussions back to the scope when necessary. The HAZOP leader should also record the findings of each session clearly and verify them with the HAZOP team members.

4 Review the HAZOP results

Review the HAZOP results to ensure their completeness and consistency. This means checking the HAZOP worksheets and reports for gaps, errors, or discrepancies, and resolving them with HAZOP team members. The HAZOP leader should also compare the results with the scope and the objectives of the study, and identify any deviations or expansions that occurred during the sessions. They should then evaluate the impact and justification of these deviations or expansions, and decide whether they need to be addressed or accepted.

5 Communicate the HAZOP outcomes

Communicate the HAZOP outcomes and recommendations to the stakeholders and project team. Present and explain the HAZOP results, deviations or expansions from the scope, and the necessary actions and responsibilities for implementing the recommendations. The HAZOP leader should also solicit and incorporate feedback from the stakeholders and document them in the HAZOP report. They should also follow up on the progress of the actions and recommendations, and ensure their closure.

6 Learn from the HAZOP experience

Learn from the HAZOP experience to improve the process for future projects. This means conducting a lessons learned session with HAZOP team members and the stakeholders, and identifying the strengths and weaknesses of the HAZOP study. The HAZOP leader should also collect and analyze data related to the HAZOP scope, such as the number and duration of sessions, the number and severity of deviations, and the effectiveness of actions and recommendations. They should use this information to optimize and streamline the HAZOP process and scope for future projects.
