design intent need to be addressed in a HAZOP study but a determination needs to be made as to which aspects should be included. It is essential that HAZOP studies identify and consider all aspects of design intent for which deviations may result in scenarios within the scope and objectives of the study. Scenarios will be missed if the

— The HAZOP method is based on the assumption that the plant under analysis is in a safe state as long as the physical operating parameters remain within a given range defined by design. Thus, the aim of a HAZOP study is to review all possible deviations (from the design intentions) for identifying whether the plant is protected …
The study leader is usually assisted by a recorder (called Scribe) who records all proceedings of the study. For each part in turn, the HAZOP study team examines each property for deviation from design intent which can lead to undesirable (or desirable) consequences. This is achieved by a questioning process using predetermined …

Hazard and Operability Studies (later shortened to HAZOP) were devised by ICI in the late 1960s, following some major problems with new, large process plants. The study was an evolution of method study and was used during the design stage of a project to identify and correct design faults which might lead to Hazard or Operability problems.
— The literature [9] describes a technique, termed Human Hazop, designed precisely with the aim of transferring the Hazop philosophy to the in-depth study of the deviations which may occur during human implementation of operational procedures.
