It is assumed that the PM lifelines in the Foundation Phase are already in place. This document details the elements of the Fundamental Phase.
There are seven very distinct elements or clusters to put in place in the Fundamental Phase. The elements are in a natural “make sense” order; some of them can be completed simultaneously if resources are available. The last one, “Basic Maintenance Management”, can and should be inserted at the right time to aid the other clusters success. We will detail the elements and begin to form a natural transition from where each site is today to where they should be. Every site is considered to be unique and having special conditions. Some sites may be more advanced then others, some sites are already performing to different degrees at levels higher than the fundamental phase. However, the elements listed below must first be established securely and be fully supported before a site can move to the next phase.
- Parts and Materials Organization
- Computerized Maintenance Management System
- Asset Classification
- Planning and Scheduling
- Work Order Process
- Preventive Maintenance Program
- Basic Maintenance Management in Place
If the resources are available you can begin setting up the elements by working on multiple ones simultaneously, some of them you will not be able to complete until others are in place. Without duplicating efforts and watering down resources, the best path to take depends on how soon you can begin to achieve or show documented improvements on asset reliability in your particular case. This has to be the primary driver of the initiative.
Parts and Material Organization – “The Storeroom Approach”
Spare parts and materials management is essential to performing effective maintenance. The path detailed below, although not the only approach, has proven to yield World Class results and will preset the stage for work orders, planned and scheduled maintenance, and a sustainable Preventive Maintenance Program, all part of the fundamental phase.
- Consolidate, select location, size and quantity of the spare parts centers or stockrooms needed:
Before you begin to prepare existing stockrooms, each plant needs to analyze and determine the best location and size of the stockrooms. Keep in mind that for best performance a single store is easier to manage then multiple ones. Sometimes satellite stores, cabinets, tool cribs, etc. add value and can be managed successfully from a central store location. The degree and quantity of information now required will probably be greater than before you organize, and all has to be entered in the CMMS in a timely fashion, if not daily.
- Place all stock items under full control (spare parts and material):
Parts storerooms must be under full control, preferably manned whenever maintenance personnel are working. If the plant decides not to man the stockroom, there must still be controlled access to the parts with full inventories at least twice per year, and frequent cycle counts of at least the critical parts. Only place parts in stock that are “new” or in “as new” conditions.
Identify locations throughout the plant where material or parts are gathered, including toolboxes belonging to the trades. At this time do not collect or recall this type until you are ready to manage them properly. As your stockroom becomes organized you can begin the process of recalling these parts then. You must eventually recall these parts because you do not want them to end up on equipment without a workorder in place, otherwise you will loose valuable history.
- Set up CMMS Stockroom Module:
The stockroom must have a fully functional CMMS with trained individuals capable of performing and running all transactions in the Stockroom Module of such system, including but not limited to issuing, receiving, stocking, purchasing, inventories, parts returns and reservations. Parts not classified “free issue” must be issued to a workorder. During transition only, the parts can be issued to a cost account at time of issue until the work order system is in place and working.
- Verify every line item in the storeroom has, without exception, all the information listed below. This information is to be loaded in the CMMS Stores Module and be used for tracking and building a comprehensive history of what part has been used where, and how often.
- Unique site part number.
- Manufacturer number
- Bin location
- Average price
- Supplier name and address (primary) and Purchasing details
- Safe lead time
- Actual quantity in stock
- Reorder levels or Min./ Max.
- Reorder quantities
- Unit of measure (UOM)
- Unit cost per vendor
- Stockroom must have procedures in place to handle the following:
- Who has the authority to purchase parts, and how much can they spend?
- A plan in place to handle returned items from the production floor and back to the vendor/supplier or to stock
- Identification of what items are considered “free” issue (no work order is required)
- Accountability for issuing, receiving, restocking and placing orders
- Low stock items must be reordered within 24 hours of reaching reorder points.
- Procedures/forms to request new items to be stocked/or to be removed from inventory
- Form available to users to track stockroom service level or customer service
- Formal method to inform users of parts requested in a timely fashion
- Area cleaning procedures, frequency and persons responsible
- Procedure established with Maintenance for replacing or substituting parts
- A method to flag overdue deliveries before they are needed
- Parts reservations for jobs in the future without having to increase the stock
- There must be designated, outlined and clearly labeled areas within the Stockroom for:
- Receiving parts, including a method of inspecting shipments
- Parts to be send out for repairs
- Parts kited and reserved for a workorder in the future
- Parts belonging to a project or reserved for one
- Terminal/screen and printers for users to query parts in the CMMS
- Area assigned for heavy items, and provided with lifting equipment as needed
- Area where parts documentation/drawing details /Manufactures information, can be obtained by the user and reviewed.
- Parts that are used frequently – usually located near the counter
- Storing PLC and circuit boards in static free cabinets in sealed envelopes
- Racks with shelves for deliveries not yet picked up by requester
- Assigned performance indicators are to be monitored by the stockroom – listed in the strategy manual
Computerized Maintenance Management System
The CMMS must act as a framework supporting all the tasks that a Maintenance Department performs. By support, I mean the CMMS serves as the primary tool to track the history of any event or transaction related to maintaining or improving equipment of all types and duties.
The CMMS must be “comprehensive”, and at the same time “user-friendly”. The real power of a CMMS is not really unleashed until the system is utilized for a while. Often, users tend to abandon the CMMS during the early stages and never get to see the real benefits. Based on my own experience, once you get over the initial challenge to put time aside and learn the system, it quickly becomes an invaluable tool.
The CMMS is simultaneously used as a guide to maintenance excellence, mainly because it forces the maintenance organization to plan and become organized. This is one of the subtlest tools designed to instill organization into fire fighting modes of operation.
Before a CMMS is installed, or when a CMMS is not supported properly, it is common to find equipment and parts information scattered, obsolete, incomplete or simply not dependable. Therefore, it is best for the installation data to be scrubbed and cleaned up before entry in the CMMS. This is accomplished by entering clean data directly into the CMMS in preparation for use. After the CMMS is introduced in the site and personnel has been trained as to what to gather in what form, the task of gathering, scrubbing and entering the basic required information can begin. As long as this is done directly in the CMMS the chances of errors are greatly reduced.
There are over 250 different types of CMMS in the market today, all of them claim to have all the features you need to run your maintenance for every size of organization available.
Early installation of the CMMS of choice as part of the EM initiative will reduce errors, work duplication and preparation of data. The format in which data is collected, organized and understood by the user should match the style and format of the CMMS of choice.
Primary Resources required:
Since this CMMS will become a central library used by many, resources will be needed to sustain the initiative during and after implementation. Below you will find the primary resources required:
- Project Manager to coordinate installation and guide the process plant by plant
- IT Support during initial installation to install hardware and required software at the plants. At present, no resources are available to support the CMMS, the EM Pillar Team is working to find an interim CMMS that can be used effectively to satisfy the CMMS element of the EM Strategy triangle.
- CMMS Training program capable of training the USERS at the plants as part of implementation and for “as needed” training for the plants during the first 12 months of each implementation AND BEYOND.
- Plant data entry personnel (must be closely supervised by the plant). Best if done internally by each plant, by the people that will be accountable for the data. Required during first 3 months of preparation for CMMS implementation.
- Complete involvement and participation by the Maintenance Manager and other key individuals in the plant during installation. Mindset change in order to move away from breakdown thinking.
- CMMS Support help desk. (7/24) and part of yearly maintenance contract administered via phone support.
- Customized report writing CAPABILITY. Because of the flexibility of the software, you can pull the same or different information in many ways to adapt to the particular need of the moment. Often as maintenance data is analyzed, you need to drill down for the root cause (similar to 5 WHY analysis). By having this important FEATURE available, the process of finding the true reason for a particular failure is greatly enhanced.
- Prepare the script and establish how we will run, utilize and operate Maintenance Company wide
- Kick off the installation in the plant by training the plant on what and how to prepare initial basic data required
- Establish the disciplines in the site for maintenance excellence, which will now include “ways of working” techniques in the CMMS
- Load, test and verify data collected from the plant
- Select and prepare plant terminals and work stations to receive the software
- Install software in the workstations at the plants
- Train the trainers on how to use the system
- Perform full stock inventory
- Support the users as required
Knowing which are the critical assets that are most important to the operation will better synchronize the available maintenance resources in order to prioritize work orders and make improvements on assets and areas that give us the most for the investment.
Asset classification will be a pull-down menu in the CMMS. Each plant will assign and enter a code for each asset stored in the CMMS. A standard document and nomenclature will be developed and given to each plant as a document. This can be executed at any time after CMMS installation. It is critical that asset classification and criticality is assigned with the full support of upper management in the plant. not just by any one area or department.
- Coordination and support by Engineering Manager, entry by Maintenance Planner into CMMS.
Maintenance Planning & Scheduling
Each plant is to assign Maintenance Planners at a rate of 1 to every 15 to 20 trades personnel. For the Planner’s job description and the Planners do’s and don’ts, see related documents EM Manual.
The Planners must be in place as early in the CMMS implementation process as possible. They will guide, along with the Engineering Manager, in the preparation of Preventive Maintenance procedures and schedules, help construct and train the trades on the work order process, help in estimating time and materials required for jobs, and help prepare the stockroom to begin Maintenance planning activities.
- Planner basic training in planning techniques and CMMS
Work Order Process
Work orders are the primary medium used by the plant to record, track and analyze history about all assets maintained. The work order should include but not be limited to information about Parts used & Labor consumed on the job. For best operation, the following should be in place before starting. All items below must interact in the same CMMS pre-selected.
- A trained Maintenance Planner for every 15 to 20 trades individuals
- A reliable parts stockroom and parts/materials replenishment system in place
- A commitment from the plant to incorporate planned and scheduled maintenance with Production Planning
- A systematic training of the trades, with disciplines in place to begin recording relevant asset information in the CMMS, which includes Parts & Labor consumed.
- Supply training to Planners in the duties of a Planner and in the CMMS
- Verification that the Stockroom is prepared to sustain the process
- Verification that Production Planning will plan together with maintenance
- Maintenance Planner to begin coaching the trades to enter the correct data
Preventive Maintenance Program
This program is one of the most misunderstood programs in the plant. For the purpose of establishing a working action plan we will first define what it means.
Preventive Maintenance regardless of who will be doing it, will include any task, observation, and inspection or act that:
- Prolongs or improves the life of an asset
- Inspection and/or detects abnormalities in any asset before they lead the asset to failure, breakdown or reduction in capacity or set reliability.
It does not include Predictive Maintenance, this will be covered later in the Building Phase of the PM strategy.
Based on this definition we can establish the action plan and the related elements.
A sustainable Preventive Maintenance program should include the following related elements:
- Analysis and review of any existing PM procedures and schedules proven to still add value
- Consultation and review of OEM (Original Equipment Manufacturer) documents
- Participation of line technicians (experts) to approve final PM procedure/inspection for the equipment they maintain prior to initial scheduling.
- Linking the procedure to the assets in the CMMS
- On-going analysis of history, and confirmation of the continued value of the procedure (usually done by the Maintenance Planner)
PM procedures and inspections should cover first the most critical assets (see definition of critical assets in PM Manual). Procedures should be implemented one by one, and immediately monitored for a while before making any additions or changes. Where a PM or inspection is not already available, just ask the local expert to give you a list with top 5 tasks to perform or check, and how often they should be done. Allow the history to tell you how to increase, decrease or remove the procedure altogether. It is more effective to start the process with an incomplete procedure then spend many hours designing the perfect one, if there is such a thing. Do not forget to include essential safety precautions or warnings and electrically disconnecting or connecting contact dangers.
Link the procedure or inspection to the asset, establish the frequency and allow the CMMS to tell you when it is due. Above all, always monitor and ask the question: “If this procedure or inspection is not done, what will actually happen”? Would the equipment fail prematurely? Could someone get hurt? Would the equipment loose on efficiency? Would the customer be affected at all?
· Single day training of PM coordinator (usually the Planner, Engineering Manager, or Maintenance Supervisor) on how to start a PM program in the plant
Basic Maintenance Management in place
Action Plan for 4 key areas
For Engineering Manager or person in charge of all maintenance activities:
- Assign others in the department to baby-sit breakdown work in order to allow himself to expand the clusters in the fundamental phase
- Must create time to dedicate to the installation of the fundamentals above on a daily basis
- Eliminate obstacles in the way of Planned Maintenance, this must be a priority (MDIST)
- Initiate development of the work force under his supervision in order to steer them away from breakdown mentality (MDIST)
- Prepare early the baseline for tracking the top three KPI’s (# of breakdowns, MTBF, MTTR)
- Assign PM team, start small, and always grow and prioritize support for this group
- Initiate documented formal training for work force
- Initiate lubricator and lubrication standards and routines, involve the operators
- Support the stockroom, especially in the beginning, establish and maintain disciplines, manage stockroom by maintenance results obtained not by parts or inventory cost control (MDIST)
- Initiate and guide maintenance training for operators (MDIST)
- Allow, promote and encourage direct interaction between trades and outside parts suppliers and vendors (MDIST)
- Fully support the Maintenance Planners, especially during initial set up
- Promote direct work order entry by the trades with monitoring by Maintenance Planners
- Expand ability to obtain live CMMS reports by trades on the floor for the equipment they maintain (MDIST)
- Set up library for drawings, equipment documentation and details, training manuals, assign a keeper, make the library available to all
- Promote planned and scheduled maintenance, say goodbye to breakdown maintenance – you are not going back that way again!!
(MDIST) Must document incidents that show this
For Maintenance Planners: (Initial phase)
- Become the keeper of the CMMS
- Obtain Planner training
- Set up close relationship and weekly meetings with Production Planners
- Monitor parts usage and where they are being used
- Help in the training of trades on the CMMS
- Monitor work order flow and what trades report back
- Maintain a work order backlog
- Do not become involved with breakdown maintenance, just monitor in CMMS
- Promote and encourage planned and scheduled work
- Monitor quality of new parts added to the stockroom
- Help Engineering Manager identify where, when, and type of training required based on work order results
- Establish report with key vendors, know their technical abilities you can tap, use them for more than just buying parts, encourage them to go to the production floor to talk to trades
- Do not under estimate jobs during the initial phase, focus on developing trust with Production Planning – this is essential.
- Monitor and always question the value of preventive maintenance work orders and their frequency. Be aware that multiple maintenance initiatives affect each other. (Ex.: starting parts lubrication and parts replacements on the same equipment at the same time)
For Stockroom (Supervisors, attendants, parts buyers):
- Maintain disciplines backed by Engineering Manager
- Do not give parts without first collecting documentation, work order number, cost code, equipment number, etc.
- Establish procedure to always check to see if part is reserved before giving it away
- Perform all required transactions in the CMMS live
- Maintain all procedures and required forms listed above in the “Parts and Material Organization” cluster
- Identify all items on the floor, nothing should be out of place, put away parts immediately, maintain 5s”
- Analyze your inventory, always know total inventory dollar, total number of line items, top 10 parts used the most, parts with no use for more than 6 months, 1 year, etc, report values to all
- Familiarize yourself with the equipment on the floor, monthly tours should be encouraged, make note of new equipment, new parts installed and parts under observation or test
- Treat the stockroom as a Bank, not Grand Central Station
For Trades (mechanics, electricians, other technical personnel):
- Obtain basic training on the CMMS
- Leave the bailing wire and the band aids at home, begin using a “fix it so that it does not break again” approach
- Document details of jobs performed on a work order, (wait for signal from planner), enter relevant data only, use established codes to ease entry
- Query reports for the equipment you maintain before starting job or for troubleshooting
- Return to stock parts you do not use, keep them clean, save the package
- Identify special tools, observations, safety precautions you find in the course of performing a job, notify the planner for incorporation in future jobs
- Identify where you need additional training
- Work with outside vendors and suppliers to test new part designs or improvements
- Help prepare operators to perform basic inspections and basic preventive tasks
- Participate in the creation of Preventive Maintenance procedures and inspections, allow the history to tell you if and when is time to modify them
- Begin to know the value of parts, query the CMMS
- Report failure trends
