 Sustainability (the following are examples only)

o Process Sustainability = total resources available / rate of consumption of resources. o Asset Condition  Integrity = Number of Threats Below Threshold / Total Number of Threats  Fleet Life = Actual Life / Target Life 2. Measurements of Theory Parameters resulting from Strategy shall be reported to the following definitions;  Use of Time Single Line process o Utilisation = Operating Time / Calendar Time NB A Single Line process is one that has only one entry and exit point for a single product (or a single entry and exit point for each separate product). If a process has a single entry and exit point but has some parallel activities within the process, it is still a Single Line process. Parallel Line process o Utilisation = Sum of Operating Time for each ‘Line’ / (Sum of number of installed Lines * Calendar Time) NB A Parallel Line process is one that has multiple, paired entry and exit points (i.e. completely separate and parallel process lines) for a single product – e.g. a fleet of mobile equipment. If a process has a single entry and exit point but has some parallel activities within the process, it is still a Single Line process.  Rate = Units of Product / Unit of Time  Quality = Units of On-spec Product / Total Units of Product  Reliability

o Time Between Interruptions = Operating Time / Number of Unscheduled Interruptions o Time Between Incidents = Operating Time / Number of Unscheduled Interventions

2. Measurements of technical theory shall be made based on the definition of the theory. There are no common standards for measures of theory.
