2 likes279 views
Under ISO55000 standards, companies must demonstrate effective management of asset data from project start to end of life. This includes having procedures for spare parts cataloging and inventory management. The document outlines RAMsoft's 6-phase process for improving spare parts inventory: 1) Audit current practices, 2) Define procedures, 3) Cleanse master data, 4) Rationalize inventory, 5) Optimize stock levels, 6) Measure effectiveness. RAMsoft tools and workshops can help companies standardize data, identify issues, reduce duplicates and optimize inventory levels to achieve savings of up to 70% according to case studies.

MRO Spare Parts Improvement Programme Conforms to ISO55000
- 1. Introduction Under ISO55000, a company must demonstrate that it is managing its assets from the project phase to end of life. For the assets, e.g. spare parts, a company must: • Demonstrate that it is managing its data (cataloguing, issue, returns, receipts, etc) • Have procedures in place (cataloguing, initial spares purchasing, inventory man) • Demonstrate risk-based decisions • Demonstrate continuous improvement In our experience the creation of MRO Spare Parts Master Data is typically done very badly at the project phase and continues into the asset ownership phase. See attached flyer, listing several case studies. Poor cataloguing leads to duplicate stock, loss of time trying to find spare parts, emergency purchases, excess stocking and hence excess costs. Depending how bad you currently are, there is a potential for significant savings. RAMsoft have been conducting workshops to help companies optimise and reduce their inventory for several years. RAMsoft have developed several tools to support reductions in inventory. • MRO-Strip, a tool to identify duplicate line items, most companies have between 10-15% duplicates • MRO-OPT, a tool to optimise stock levels and to show % cost savings • MRO-BOM, a tool to support BOM building • MRO-Auditor, for conducting MRO Spare Parts Master Data Audits very effectively • MRO-CleanIT, to cleanse the spare part master data with standardised part descriptions and part numbers RAMsoft have also developed an inventory reduction process based on the following 6 phases: Audit Define Process & Guides Cleanse Rationalise Optimise Measure Effectiveness Is Your MRO Spare Parts Improvement Programme ISO55000 Compliant?

- 2. Phase 1 Auditing The first step for any inventory improvement programme is an understanding of the company’s issues. The scope of an inventory management audit can cover the following areas: • MRO Best Practices (a structured questionnaire is used to evaluate best practices in managing spare parts effectively) • MRO Written Procedures and Guides (the documents required for each phase of an item’s life) • Master Data Review (short description formats, nouns and modifiers, Mfg. & Vendor P/Ns, Vendor and Mfg. names, review of duplicates) • Inventory replenishment control parameters (an evaluation of current ROP, OQ, Min-Max, etc) In this document, we will mainly discuss activities related to spare parts master data. A company’s downloaded inventory data is mapped and imported to our MRO-Auditor tool. MRO- Auditor contains over 200 saved filters and queries to facilitate the master data review by noun, etc. A report is issued detailing the findings good and bad - remember poor cataloguing represents potential savings. Typical findings from our audits are: • Short descriptions have inconsistent formatting • Qualifiers or Modifiers are not identified • Vendors’ names included in the short description • Lack of attribute data in the short description, and inconsistent sequencing • MPNs have inconsistent formatting • MPNs fields are a mix of Vendors and MPNs • 10-15% duplicate line items • Inconsistent abbreviations used • Abbreviations are not used when they should be • Multiple suppliers for the similar material Comments on poor cataloguing will be supported by screen shots from the MRO-Auditor tool, a typical example is: The above is an example of the poor cleansing delivered by a consultant. RAMsoft do not guarantee to find all types of inconsistencies, but the most common. Only during master data cleansing will all issues be identified. Phase 2 Procedures and Guides ISO55000 states that a high level strategic plan (known as a SAMP) needs to be developed. The structure of the SAMP varies between consultants and the various maintenance associations, this is because the ISO55000 is not prescriptive. The SAMP developed by Ramsoft, includes two elements relative to MRO Spare Parts: • Initial MRO Spare Parts Planning (Project phase) • MRO Spare Parts Management (Ownership phase)
- 3. The main reason for poor cataloguing, is that the cataloguing process is not documented in the project phase, which includes CMMS population. Even when a so called consultant has carried out the cataloguing or the cleansing the final quality is poor. Unless you document all the rules and build criteria the cataloguing will not achieve a high quality. Remember under ISO55000 you must demonstrate the management of data and that means how the data is populated in the CMMS consistently During the data cleansing phase, RAMsoft can prepare documentation that supports consistent cataloguing in the future. Documentation can include: • Guides and rules used during the cleansing • A list of all abbreviations • Type guides to cover the type of spares stocked and the naming convention The screen shot below, shows a typical Type Guide for Shaft Bushes. Phase 3 Cleansing Master Data The scope of cleansing will vary from company to company and will be CMMS dependant. For example, Maximo users typically describe their spare parts using up to 75 characters, while SAP users are limited to 40 characters. This means a SAP user must use many more abbreviations to describe a spare part. RAMsoft using their MRO-CleanIT tool can clean up your master data. Using standardised descriptions, a) located in a look up table when matched to a MPN and b) a table containing template descriptions, when that MPN is not an exact match. One of the reasons for duplicate stock is manufacturers & vendors use different naming conventions, e.g. see for stainless steel A2, 304, SS, they could be all the same but used in MPN then you would not be able to identify these. Therefore Phase 2 is essential, you must clearly identify your naming conventions. Benefits of cleansed master data are the identification of potential duplicates, ease of finding spares, identification of standardisation and rationalisation opportunities and hence inventory reduction. The following example shows the current part description and the cleansed description.
- 4. Phase 4 Rationalisation Rationalisation is about reviewing your material and seeking inventory or cost reduction opportunities Companies who have proceeded to the cleansing and rationalisation phases have achieved up to 60-70 % reduction in line items (for some material) by: • Standardising part descriptions and MPNs • Removing duplicates • Standardising on the material specification • Reducing the number of manufacturers • Removing stock that is not fit for purpose (wrong specification) The screen shot below shows that this company stocked 23 different manufacturers of bearings. Rationalisation covers many of the 30 tactics, we cover in our 3 day workshop, including: • Classifying the criticality of each spare • Assigning classifications for ABC, HML, XYZ and demand classes • Identifying OPMs and APMs • Reducing stocking locations • Conducting RCA for A items • Conducting Spend Analysis • Challenge stocking of slow movers • Etc. Further cost savings may be possible by proceeding to Phase 5 MRO Optimisation Phase 5 Optimisation Optimisation supports ISO55000 by making decisions based on risk, we set a Stock-out risk for each spare part based on the item’s criticality. Opportunities for reducing inventory are identified by determining the optimum ROP and OQ and then the most appropriate replenishment strategy. Optimum ROPs are determined by: • Assigning a service level to each spare part based on its criticality • Identifying the true lead time (company plus supplier)
- 5. • Determining the average demand rate RAMsoft propose three main replenishment strategies: • ROP a fixed ROP and OQ • Min-Max, a variable OQ to bring the stock level to a maximum • Constant Vendor Delivery, based on JIT concepts Costs savings are identified by looking for potential cost savings. Prioritisation is based on differential financial value between the current average stock level and optimum average stock level. The case study below is an example, where the optimum values are not appropriate, the options are then to a) increase one or more control parameters, so that they are not the optimum values or b) move to a different replenishment strategy. In this example a) was the best option. The Author David Thompson holds a B.Sc.
