1. Major Outage – Sustainable Savings
Part 1 - Outage Scope Document Control
Loose control over scope documents led repeatedly to multiple versions of the same document
being circulated. This resulted in incorrect target prices, inaccurate scheduling and variations
(CMR’s) to clarify or modify the actual work to be done.
A system was introduced to impose a discipline over scope documents to ensure “one version of the
truth”
This was initially introduced for U4 2014 Major Outage. The step change in CMR’s arising from scope
related issues was dramatic. The system was refined slightly for U2 2015 Outage based on learnings
from U4. The positive results continued.
This following graph shows the value of CMR’s raised due to uncertainty or changes or redefinition
of scope.
U3 2013 was the base year – CMR’s with a root cause due uncertainty regarding scope content
totalled $1250k.
Following the introduction of the scope document management system, this fell to $254k in 2014 U4
and improved further with U2 2015 falling to $193k.
Scope owners and Partners embraced the system. Following established processes resulted in a step
change saving of over $1M which is clearly sustainable as the result was improved in the subsequent
outage.
