Programme evaluation review technique

Project network techniques provide a means to determine the sequence of activities and their subsequent scheduling. Through a network analysis process, also referred to as CPM (critical path method) or PERT (programme evaluation review technique), constituent project activities are assembled into a logical, diagrammatic model, and then analysed in terms of time and resource. The planning sequence runs as follows ... 

Continuing the orientation towards the complete system, this part of the EWICS TC7 programme is reviewing and evaluating design techniques... 

Critical path analysis and programme evaluation and review techniques are examples of project network techniques. 

FMEA is used to assist analysts to perform hazard analyses and it is regarded as a supplement rather than a replacement for hazard analyses. Safety analysts can use FMEA to verify that all safety critical hardware has been addressed in the hazard analyses. The FMEA for hardware systems is an important technique for evaluating the design and documenting the review process. All credible failure modes and their resultant effects at the component and system levels are identified and documented. Items that meet defined criteria are identified as critical items and are placed on the Critical Item List (CEL). Each entry of the CIL is then evaluated to see if design changes can be implemented so that the item can be deleted from the CIL. Items that cannot be deleted from the CIL must be accepted by the programme/project, based on the rationale for acceptance of the risk. The analysis follows a well-deflned sequence of steps that encompass (1) failure mode, (2) failure effects, (3) causes, (4) detectability, (S) corrective or preventive actions, and (6) rationale for acceptance.
