Possible Lines of Team Communication

Several factors have been noticed to influence the speed and accuracy of the review process. 

If the time to review a design continues more than a week, the review process becomes more laborious and unfortunately maybe boring to the team members. Personnel will become less interested in the actual review at hand and desire to get back to their normal activities and co-workers. This longing for the routine work activities will necessarily distract from the contribution and therefore effectiveness of the HAZOP or What-If review. 

If a final HAZOP review is to be performed on a design that is say only 75% complete, the review team will necessarily have a lot to say about the unfinished portion of the design. The scheduled review method should be consistent with the level of design that will be presented for review. 

If most of the review team members has never participated in a HAZOP or What-If review, they will necessarily be lost and only learning the process during the first day or so. The team leader will be striving to instruct the team members rather that have them contribute to the review. 

The success of the review lies with the team leader. His whole purpose is to lead the team through the review and bring out the concerns of the process. If he is ineffective the team will perceive this and not contribute effectively.
