System safety in design practice: Two work models compared

From: Professional Safety | Date: November 1, 1999| Author: | Copyright information

In the traditional approach to design, one team of designers and a second team of safetyreliability reviewers function independently and sequentially. This serial paradigm is costly-both in schedule time and in the expense of retrofitting designs found to be deficient.

In an alternate-and increasingly practiced-work model, designers apply the methods of system safety analysis and reliability engineering concurrently with design evolution, while system safety and reliability engineers foster the process. Resulting designs are finalized earlier, using fewer manhours, and are less likely to ...
