Six Sigma in energy transportation

Examples of measurable indicators for the specific activity of transport of energy can be: Quantity of electricity delivered, coefficient of losses, average unavailability in time of facilities, line length unavailable for event, transformer / auto transformer nominal apparent power (MVA), the duration (time in hours) of unavailability to the event, etc.
An example of a successful project using Six Sigma is “decrease downtime “. The key indicator which give the performance of the process and choose to be improved is downtime (Ti), in other words it's time due to electricity power failures. In defining the problem, the process is identified and the team which will work on this project. Specific tools this phase (Define) for this case can be: process map and collect voice of customer VOC.
