Powerlink

Powerlink is a leading Australian Government owned provider of high voltage electricity transmission network services, combining innovation with insight to deliver safe, cost effective and reliable solutions.
Powerlink would like to provide relevant users with the required Thermal and Fault Level (TFL) ratings data in an easily accessible, meaningful and timely manner with a high degree of accuracy. This is critical to ensure the Network is operating at optimum capacity.
Managing the TFL ratings were difficult and time consuming because;
- of the inconsistent use of various IT systems and supporting documents to capture and calculate the ratings
- no guidelines or urgency to update the ratings regularly, timelines/deadlines were not the same for everyone
- there was no single source of truth and
- the business could not trust the data quality of the ratings leading to over-designed components i.e.
  increased manufacturing costs or under-designed components leading to network failure.

Interviewed key Subject Matter Experts (SMEs) to scope the process
Performed a stakeholders’ analysis
Workshopped the process with stakeholders and documented the
As-Is end-to-end process
Identified and prioritised the improvement opportunities
Developed, reviewed, updated and signed off the To-Be improved
end-to-end Rating Management process.
The process captured the roles and responsibilities; systems used, business rules driving the process as well as supporting documents which were or should have been used.

Reduction in cost and frustration levels within the organisation (particularly during project implementation) as a result of;
- Reducing the rating release time cycle from 8 weeks to near real-time displayed on SAP
- Better management of delays within the process
- Eliminating bottlenecks that could be identified earlier in the process
- Improving the quality of the TFL ratings data, which restored the credibility of the data and
- Eliminating rework

Business has a clear understanding now of which systems/data sources are supporting which part of the process for change management and future IT projects
Safety improved, since Managers can now make better informed decisions about their limited resources and easily share explicit and tacit knowledge about their process (knowledge handover/retention)
