Project for Reducing TAT Variation of breakdown of Maintenance Equipment

  1. 1. Voice of the Customer-VOC (Internal Customer)2Customer Comments Critical to Quality-CTQ’sPM (Internal Customer) The breakdown time of failure isgreater than target time as per lastthree months data and it has beenimpacting company as theorganization will have to pay hugepenalties to MInfra.Increase TAT of breakdownmaintenanceMaintenance Manager Onward rectify time of non criticalfailure of AFC machines isimpacting on going maintenancedue to high maintenance cost i.e.large penalty amount.Increase TAT of breakdownmaintenance/PenaltydDEFINE

  3. 3. Project CharterABC PVT Ltd, is repudiated mutibranded AFC system organisationwhich is being operated in more than 100 countries. It providesservices of design, supply, installation ,testing and commissioning ofAutomatic fare collection ticketing systems. AFC system reduces theticket checking staff and it helps the prevent fraud .XXX is one of the clients to ABC, XXX is one of the biggestinfrastructure organization for developing the Metros in India.It deals with the Minfra for 5 years warranty services in maintenance ofAFC equipments for six metro stations. The organization will start thewarranty period of maintenance from starting day of metro station .Ithas been clearly mentioned in AFC contract if the failures rectify timeof AFC equipments would be greater than one hundred twentyminutes in critical and non critical conditions then the organization willbe paying the penalty of 3.5 lkh per hour. At BB ABC, It has beenobserved that failures rectify time of AFC equipments is greater thanone hundred twenty minutes in last three months data (July 2011 – sep2011) by prescribed the target in contract Consequently this is hugeimpact on project by maintenance penalty amount Rs 4,10,37500.TeamVice President: LMManaging director MOProject Manager: RRMaintenance manager: GSBB: SBGB: RP ,MA, RLMember: Maintenance TeamFinancial controller: RGProblem Statement:Last 3 month penalty of breakdown the AFC machines Jul , Aug &sep is respectively (15732500), (13206667) & (1209833) cr. The deficitof total revenue in last 3 months is Two million seventy eight lakheighty three thousand three hundred thirty three.This resulted probable delay of expansion plan of business &exposure to aggressive competitors in near future.Goal Statement :To achieve the TAT of breakdown maintenance is 120 minutes and reduce thevariation in my process by the end of March 2012.In Scope : Maintenance ,Hardware & software developmentdepartment.Out Scope : All other department other than Maintenance ,Hardware &software department.Milestones Target Date Actual DateD 15thMarch 11 30thMarch 11M 1stApril11 15thNov’11A 16thNov’11 30thNov’11I 1stdec’11 6thDec’11C 6thDec’11 15thDec’11dDEFINE
