• operating stability and rates, • control of modification of design, use or operation, • maintenance people, hardware and software, • the required Functional Life of the process.

The characteristics for each probable threat for a process, as shaped by the context for the process, must be defined in order to evaluate the merit of the Service strategy options.

Purpose

To specify the characteristics for each risk.

Quantity

• One specification for the characteristics for each probable risk. • ORM Layer 1 Hazard Inventory and Baseline WRAC detailing risk characteristics through hazard characterisation and unwanted event and related consequences descriptions. The detail may be defined in ORM Layer 2 Issue Based Risk Management processes where detailed analysis is undertaken if uncertainty is identified in the ORM Baseline Risk Management information. The specification for risk characteristics shall include; • The Serviceable Item (this will typically be an activity, workplace, equipment used in the Work Management process). • The probable unwanted events identified. Each distinct combination of hazard types (stress, chemical, wear, fouling, obsolescence) and the trigger (arising from either design, operation, people or environment) will have different characteristics and hence must be treated as a separate threat. • Date of risk characterisation. • Personnel and organisations performing the characterisation. • The data sources on which the characterisation was based. • The potential consequences of the identified unwanted events (this may include; safety, environment, health, revenue, costs, reputational, regulatory and social impacts). • The probable exposure to each of the consequences if the unwanted event occurs (ideally each consequence should be treated separately but in some cases it may be reasonable to group some consequences (e.g. safety and environment, business risks) and estimate the exposure for the highest consequence/exposure combination for each grouping. • The shape of the risk probability distribution. This may be expressed as a function of either calendar time or an operating parameter such as hours, tonnes, etc., whichever is the most appropriate. The minimum requirements should be to specify; o The dominant development pattern(s), i.e. infant mortality, random and/or wear out characteristics. Note that with the Quality
