This analysis typically takes two forms, hazard analysis and risk analysis. Unfortunately, while many people may be expert in the operation of a component or sub-system, knowledge about interactions with people and the environment is not necessarily as widespread.
The next logical approach is to look at the language devices and patterns and form of the text structure.
In common usage, however, risk analysis without probabilities is hardly ever performed, and so risk analysis is typically used to refer to the combination of the two.
The movement is also referred to as formalism or structuralism. Should safety be measured in the amount of harm done, or perhaps a ration of the amount of harm done vs.
They may be based upon older systems that have some fundamental or perhaps subtle difference in their operation. Limits, in the forms of levels of abstraction, are necessary to allow people to perform the analysis, as humans are bad at dealing with high levels of complexity.
Hazard Analysis A hazard is a situation in which there is actual or potential danger to people or the environment. However, as we are increasingly finding in systems in the field, the added complexity of automation causes unsafe conditions to be overlooked or improperly protected against.
The combination of these two values can be an extremely valuable tool for prioritizing further work and determining when the system is safe enough.
An event tree attempts to enumerate a list of components and subsystems and determine the result of their operation or non-operation. And how can one system be said to be safer than another? Once this enumeration of possibilities has been done, the analysis can proceed into its probabilistic phase.
The best known post-structuralist approach is deconstructionism. All too often the true test of how safe a system is occurs in the field, and the best measure we have is the hazards and harm it does cause, rather than the ones the analysis has prevented.
While this method can be used to show complicated interactions, it is still subject to the danger of overlooking aspects of the system as these are mostly enumerated.
If the annalists are inexperienced, or not familiar with the ways in which systems present risks, then the analysis will suffer, and no methodology can completely make up for shortcomings of those performing the analysis.
It is important, therefore, that the model for the system extend to the appropriate levels of detail as well as supporting analysis at higher levels of abstraction.
When tied together, the two forms of analysis can provide a detailed and potentially prioritized list of the potential harm that a system can cause. This safety expertise is still held by people, rather than having been encapsulated within the analytical methods themselves, and will remain so for the foreseeable future.
If the system is operated outside the specified environment, then the analysis is invalid. As an example, an airplane is a safety critical system.
Once the examination has been performed, these forms or diagrams or other tool of the method can be used to quickly summarize the result. Often, if no data exists, the numbers may be based on the gut instinct of the person performing the analysis. An often-repeated statement from Marx expresses a basic idea specific to this form of criticism.
Each potential harm is associated with a probability of occurring. It places limits on the way the system is examined, and those limits can be fatal weaknesses at the heart of an analysis.
Such a stab in the dark may be fairly accurate if made by someone competent, but even competent people and analysts can make mistakes, or misjudge dangers based on personal prejudices.

This analysis typically takes two forms, hazard analysis and risk analysis. Hazard analysis is the examination of a system for potential to cause harm.
In it the system or a model of the system is examined for ways in which it can cause harm or dangerous situations.

Literary analysis is a critical response to a literary text in the form of a critical essay or an oral commentary. It includes a thorough interpretation of the work. Such analysis may be based from a variety of critical approaches or movements, e.g. archetypal criticism, cultural criticism, feminist.
