1   Scope This Draft for Development gives guidance to engineers and managers on the basic concepts of human reliability, in the context of industrial processes and products. The principles of human performance are introduced to explain how human errors arise and how improved operational competence can be achieved. A range of techniques for qualitative and quantitative assessment and improvement of human reliability are provided. The application of these guidelines and techniques can help to optimize human performance in process/product design through the inclusion of human reliability considerations throughout the product life cycle.

NOTE 1 It is not intended to provide engineers with the competence to solve all human reliability problems, but to provide an awareness of their potential to exist. The appropriate and timely involvement of specialists can then be provided for in the design and development programme.

NOTE 2 Case studies using qualitative and quantitative methods are given in Annex A and Annex B respectively.
