Second, the human factors practitioner should consider the measures of effectiveness of the system that the model should be designed to predict. In building the model, it is important to remember that the goal of the model will be to predict measures of human performance that will impact system performance. Therefore, a clear definition of what is important to performance is necessary. The following aspects of performance measures should be considered ... 

In some places, that art and science has been called human factors engineering. Dr. Alphonse Chapaitis gave this definition of human factors engineering in his article To Commuiticate the Human Factors Message, You Have to Know What the Message Is and How to Commuiticate It. ... 

Human error and human factors are often used interchangeably, thus creating confusion and compromising the quality of human reUabilily assessments. Therefore, defining human factors and human error is necessary to establish a basis for the discussion in the current paper. A definition of human factors, modified slightly from the UK s Health and Safety Executive (Health and Safety Executive 1999), is as follows (DiMattia 2005) ... 

Reason s book was written for cognitive psychologists, human factors professionals, safety managers, and reliability engineers. His definition covers all the bases, but is not quite as specific as is needed in the occupational setting. 

The components of the SCMM were based on the safety culture features listed in the Health and Safety Executive s human factors guidance document HS(G)48 (HSE, 1999). The initial model was tested by interviewing safety experts, operational managers, safety representatives and frontline staff about their company s safety culture development and the applicability of the SCMM. This led to the definition of a Safety Culture Maturity Model, with five levels of maturity (as shown in Figure 1) and ten elements, namely ... 

Requirement, definition, and clearance for bypass/inhibit/override to specify any action needed to achieve and maintain safe state for such actions human factors should be taken into account... 

As written in the Definitions, the term socio-technical system pertains to the interrelatedness of the social and technical aspects of an organization. The term is commonly used in sociology, psychology, and human factors engineering. Quite probably, safety professionals will see a more frequent use of the term in their literature. It implies taking a holistic approach to operational risk management—emphasizing the importance of the whole and the interdependence of its parts. 

One of the principles of a MAPP is that the dutyholder should develop and implement procedures to systematically identify and evaluate hazards arising from their activities (in both normal and abnormal conditions) (L111). These procedures should address human factors with the same rigour as engineering and technical issues, and should be described in the SMS. There should also be systematic procedures for the definition of measures to prevent major accidents and mitigate their consequences. 

This chapter will outhne the general methodology for investigating occurrences from a human factors perspective, and will introduce the terms and definitions used by the TSB. These human factors investigation methods and definitions have been... 

Three nonsafety tools are used in safety analysis failure modes, effects, and criticality analysis (FMECA) human factors analysis and software analysis. Because these techniques are extremely helpful in finding eqnipment failures, human errors, and software mistakes, safety engineers have coupled them to their safety analyses. It is definitely worthwhile to understand how these tools can benefit you. 

The first example reflects human factors best practice by illustrating the use of a freely available HTA tool. This tool enables many of the basic requirements of BS/ EN/ISO 11064-1 2001 to be met, including the definition of task requirements, using the outputs of the HTA, combined with heuristics, in order to perform a preliminary allocation of function, then going further to help meet the requirements for job design.

One of the problems related to the work organization in the forest sector is the definition of efficient production targets consistent with the ergonomic factors associated with the work and the workers, such as thermal environment of the workplace, exposure to noise and vibration, physical load required and repetitive use of the upper limbs. The production targets, historically, has always been determined by motion and time studies, and measures of production (Stanton et al., 2004). However, the definition of production targets humanly sustainable must also be taken into account human factors and those affecting its limitations.

The system definition is utilised to analyse the implications of the change on the system and identify detailed requirements against the deliverables, including, Systems Safety, RAM, Human Factors, Operational Readiness, EMI/EMC and Performance.
