What factors influence human being reliability

Human Nature

Collecting data allows theorists to categorize errors and utilize this information to supply clues as to the processes linked to routine man action. For practical application it is crucial to understand the errors staff are likely to generate. Steps can be taken to remove them or perhaps, if this is impossible, to minimize the outcomes.

Humans can make problems at any time. Having less precision in physical operate or incorrect timing of actions that people display at at times means that something unpredictable may happen.

Whilliams has described the main factors behind human problem:

• unfamiliarity: a situation is very important but happens infrequently or is new
• time shortage: not enough time is available for error diagnosis and a static correction
• understanding: not any means offered to convey information so that it is easy to understand
• Mental designs: the way the user imagines a system to work is different to how the designer imagined this
• information overload: simultaneous demonstration of information goes beyond a person’s capacity to understand
• fresh techniques: the necessity to learn fresh techniques that might follow philosophies opposing those that have been utilized previously
• identified risk: you see, the risks present are more than the person involved realizes.
• feedback: program feedback is definitely poor, unclear, or incorrect
• conformation: simply no clear conformation is available from your system of the action that is required to control it
• inexperience: the circumstance present requires knowledge, to understand and control the case, beyond those of the person engaged
• information top quality: specified types of procedures, or guidelines from other humans, are of poor quality in a way that they are improper to the scenario present when followed
• selection: the system does not have any diversity to permit checking details presented
• physical ability: the person does not have the physical ability to perform the necessary tasks
• mental stimulation: anybody is required to spend a lot of time both inactive or perhaps involved in very repetitive, menial tasks
• disruption: work patterns cause disruption to normal sleeping and relax cycles
• pacing: other people impact the rate at which responsibilities can be performed
• over manning: more people present than instructed to do the job satisfactorily.

Human variability

A lot of design function assumes good engineering practice will be accompanied by all individuals with any influence to the system. 55 that this cannot be guaranteed. Human performance depends on a lot of factors which means they will perform in another way in different conditions. Such basic principle factors that may effect kinds performance might include:

• reaction to pressure
• fatigue
• supervisors expectations
• interpersonal interaction
• social pressure
• group interaction and identification
• team efficiency spirits
• time at the job
• idle time
• repetition of work.

These elements should be taken into consideration when considering basic safety. It is also important to consider these factors when choosing personnel or setting up groups.
