Total project planning: Integration of task analysis, safety analysis and optimisation techniques

This chapter presents a methodology for the elicitation of the information required to fully plan a maintenance activity, and assesses both safety and efficiency goals. The methodology is based on a participatory approach that harnesses the existing knowledge in the organ-isation and engages key stakeholders in planning activities to help ensure safe and timely completion of activities. The data collection and analysis is based on bottom-up estimation techniques captured in a tabular task analysis that is subsequently used as the basis of the risk assessment. Task analysis is the human factor equivalent of a functional analysis in systems engineering. Task analysis identifies and examines the tasks performed by human operators when interacting with the system. The task analysis is used as a baseline for a Hazard Identification Study. The Hazid study involved a team workshop exercise with the team having the appropriate expertise, including knowledge of the plant and the planned operation, safety analysis, and human factors knowledge.
