Engineering Design Reviews

Engineering design is usually a collaborated effort. Different teams from different disciplines of engineering need to collaborate on the same project. Naturally, the work done by each team / participant needs to be reviewed by others on regular intervals. Engineering Design Reviews are meetings held for these review sessions where different stakeholders can develop a better common understanding of the work in progress.

Depending on the engineering deliverables being reviewed, there are some commonly practiced review meetings which have now become quite standard. This post contains objectives and basic description of activities performed during HAZOP, PSSR, Fire Safety Review etc.
