Vishwadeep Khatri replied to Vishwadeep Khatri's topic in We ask and you answer! The best answer wins!As mentioned by Venugopal, there may be a need to use Hypothesis testing in any of the phases. Some examples are given below 1. Define phase - To check if the current performance is indeed below the expected performance. improvement (difference from existing performance) 2. Measure phase - During MSA as mentioned by Venugopal. After capability assessment - to verify if the Goal really indicates a significant improvement over the current performance. 3. Analyze Phase - To verify root causes. 4. Improve Phase - To compare before and after improvement performances. 5. Control Phase - To check if improved performance has been sustained and no difference is found after controls are put in place.

Dear Vishnu, I am unable to share experiences here but I can assure you that immense opportunities exist w.r.t improvement in Emergency Services. Projects can be identified through all the three sources - Voice of customer - Expectations, Satisfaction Levels, Referal business growth, etc. Voice of business - KPI performance, business growth, revenue growth, etc. Cost of Poor Quality - Lost opportunities, improved response times, etc. Hope this helps.

Hi Ransingh, Overall Equipment Effectiveness which is the product of Availability, Performance and Quality can't be obtained via MTTR, MTBF and MTTF for the equipment. This is so because the three measures do not relate to Performance or Quality. If you know MTBF and MTTR, you should be able to calculate availability losses that are due to unplanned stoppage due to machine failure. However planned stoppages (like change over time) which are part of availability calculation in OEE will still be hidden. Also, unplanned stoppage due to other reasons like power failure (MTBF may not consider power failure as equipment failure based on a common definition which considers only equipment malfunction as failure) will also be hidden. To answer your question, OEE cannot be inferred from those numbers. OEE, for utilities, as a metric, may not be a great measure of performance but that is a different topic to discuss.
