Quantity

• One decision whether the performance target confidence level for the selected Service Strategies meets the confidence level set for the process performance targets.

Quality

The statistical model for estimating performance confidence levels shall be the standard Operating Model value driver tree model for strategy characteristics.

The performance loss estimates used for the model shall be those determined in TA SS.11 – Develop Statistical Loss Projections.

If the estimated confidence levels on performance targets is between +0 and +5% of the target set for the asset the confidence levels shall be considered to be meet the target and the selected Service Strategies shall be incorporated into the Operating Master Schedule. If the estimated confidence levels fall outside of this range then the process of Setting Performance Targets must be revisited to decide whether to;

• try a new package of strategies, or • set new performance targets, or • lower the confidence level that will be accepted.

Time

After any change to the Service Strategies is proposed.

The Service Strategies shall be specified during establishment of a process.

Review and validation of Service Strategies shall be based on the benefit ranking of improvement opportunities identified through analysis of performance.

Resources

The identification of potential strategy options is the accountability of the role specified in the configured flow chart.
