program Questions?
Agenda
Human resources and effective people management- Heart of every successful operation
Equipment Standardization- Cohesive goal of maintenance and engineering organization
Scope- Topics not included
Often ignored part of maintenance No faith on the spare parts personnel Cubby holes of spare parts spread all over the
field- technicians’ cars, field, near equipment & the stockroom
Spare parts- an afterthought of project work Insufficient infrastructure investment Time & management oversight required for a
successful spare parts program
State of spare parts in the industry
Desired State
Transactional accuracy
Reliable & dependable- 1 central repository or controlled secondary repositories
Predictive spare parts requirements planned in
advance

High Spare parts
Availability
“Right parts in the right place at the
right time with optimum inventory”
“Right parts in the right place at the
right time with optimum inventory”
High spare parts availability-1 (#of transactions in which spares not
available)*100/ (Total number of transactions)
High availability should be goal if downtime costs outweigh spare part costs
More onsite parts = More $ = Less Risk
High spare parts availability-2
2 Key steps Control Introduction of new equipment and
spare parts - Engineering Change Control process incorporates spare parts
Perform spare parts gap analysis on Each unique piece of equipment List of spares reviewed by technicians Purchase of missing parts- $ spend based
on downtime risk
High spare parts availability-3 Established equipment spare parts guidelines
BOMs, drawings, minimum spare parts required at install etc.
Establish templates
Spare parts description (nomenclature) standardization
Equipment type standardization
CMMS-Maintenance & spares integration-1
Heart of maintenance
Spare parts integrated with work requests
Visibility to BOMs & drawings of equipment –procuring non available parts

Sample CMMS spare parts report and benefits Usage tracking of spare parts Rootcause analysis Unit spare parts usage & cost of unit piece of
equipment Base information for prediction of spare parts
usage modeling
Improved MTTR
Base of Transactional Accuracy

CMMS-Maintenance & spares integration-3
World-Class Storeroom Processes-1“Audit & verify processes”
Right parts in right locations.
Correct stock levels minimum stocked quantity & ordering quantities
Adequate stocking locations
Inventory accuracy periodic cycle counting
Storeroom metrics- Periodic reviews $, usage, red flags Availability Shrinkage (lost parts) Stockout % (parts not available)
Rootcause fixes if issues discovered Min stock & ordering qty determined for each
part. Take assistance from statistical models Perpetual ordering of parts based on min
stock Below min stock report
World-Class Storeroom Processes-2
Centralized location
Controlled access
Labeled shelves & bins Open Shelves - non-controlled parts Pallet racking - Heavy items Automated Carouse - Fast movers and controlled items
World-Class Storeroom Processes-3
Open Shelving
Binstock parts- nuts, bolts, etc. Fasteners, Tools etc.
Pallet Racking Storage
Automated Storage Carousel
