“The systematic and coordinated activities and practices through which an organization optimally manages its physical assets, and their associated performance, risk sand expenditures over their lifecycle for the purpose of achieving its organizational strategic plan”.
Or, more simply, "the optimum way of managing assets to achieve a desired and sustainable outcome".

Risk-based Inspection Analysis
Risk-based inspection analysis (RBI) is a methodology which aims at establishing an inspection program based on the aspects of probability and consequence of a failure. The methodology combines production assurance and risk-analysis work and is typically applied to static process equipment (e.g. piping, pressure vessels and valve bodies). The failure mode of concern is normally loss of containment.

Reliability-centered Maintenance Analysis
In a reliability-centered maintenance (RCM) analysis that has proposed to establish the (preventive) maintenance program in a systematic way, the following steps are normally covered:
• functionality analysis, which defines the main functions of the system/equipment;
• criticality analysis, which defines the failure modes of the equipment and their frequency (for which FMECA can be used);
• identification of the causes of failure and the mechanisms for critical fault modes;
• Definition of the type of maintenance based on the criticality of the failure, the failure probability, the maintenance cost, etc.

Fault Tree Analysis
This is a graphical, top-down method used to analyze the logical links between failure of an overall system and the failures of its components and to perform probability calculations.

Failure Modes and Effects Analysis (FMEA) and Failure Mode, Effect and Criticality Analysis (FMECA)
An FMEA is a systematic technique for establishing the effects of potential failure modes within a system. The analysis can be performed at any level of assembly. This can be done with a criticality analysis, in which case it is called an FMECA.

FMECA is a semi-quantitative analysis, where the failure probability and the consequence data are used to assess the criticality of each failure mode. It is a systematic methodology to increase the inherent reliability of a system or product. It is an iterative process of identifying failure modes, assessing their probabilities of occurrence and their effects on the system, isolating the causes, and determining corrective actions or preventive measures. When the analysis is done from a functional standpoint, it is usually performed at a plant or unit level, whereas if the focus is on the hardware, it usually descends down to the maintainable-item level. The amount of data required is different depending on the focus.

Hazard and Operability Study
The purpose of a hazard and operability (HAZOP) study is to identify hazards in process plants and to identify operational problems and provide essential input to process design. Besides being useful from a production assurance point of view, the HAZOPs can also be used to identify alternative safe ways of operating the plant in an abnormal situation to avoid shutdown.
