Performance Evaluation in Maintenance Contracts: Evaluate Efficiency and Check Costs
Objective: In our institution,penalties were introduced as a driver to increase the vendors performances,in terms of SLA and incident closure time,with little success,since statistically critical devices continued to keep the same downtime.This is why better performance indexes were defined and tested on active contracts of different vendors.Methods: The new indexes were grouped in two categories: quality indexes and economical indexes.Then the two sets were applied to different contracts in order to be tested.Two contracts were chosen among those available due to device classes comparability,since they contain the same type of devices and mainly the same number for each class.Results: The following indexes were calculated,IQUAL ranged from 0 to 7 for contract A and from 2.3 to 17for contract B.npenalties are 65 for contract A and 41 for contract B1 but assets in contract B are fewer.%penalties range from 13% to 63% for provider A and from 24% to59% for provider B.With regard to tsolution mean values range from 0.14 to 2.18 d for provider A and from 0.78 to4.06 for provider B,tanswer mean values range from 0.44 to2.23 d for provider A and from 0.09 to 2.23 d for provider B.The mean value of %(ε)penalties is more or less 4% for both vendors.Conclusion: The proposed indexes proved to be easily calculated-the easier the more data are traced on a asset management software-and can be used to evaluate a contract performance.Indexes help improve efficiency in maintenance but show that device downtime is due to many different causes and cant be easily reduced beyond 5% to 10% of yearly use of the device.Moreover,tsolution,,indicates that the vendors performance is mainly related to its organization; the presence of penalties in the contract didnt turn out in a major reduction of such index.
