Best Practices for Developing Equipment and Inventory Descriptions for Efficient Maintenance Management

Question:

I am in the process of implementing a Computerized Maintenance Management System (CMMS) at my manufacturing facility, and unfortunately, the corporation has not provided any specific guidelines for equipment and inventory descriptions. They have simply suggested using whatever works best for us. However, I am unsure of what would work best for our facility and am seeking insights from other companies in similar situations. One approach we have taken is naming equipment based on what operators commonly refer to it as. Our system automatically assigns inventory numbers, so I am focusing on creating detailed descriptions for parts identification. My goal is to establish a standardized description format based on equipment models. For example, if a pump is utilized in multiple locations within the plant, I aim to maintain a single set of parts for all pumps in that group, rather than assigning separate item numbers for each location - a practice that previously led to inventory management issues. How would you recommend handling parts specific to a particular pump model? For bearings, I have adopted a naming convention that includes details such as size and clearance. When it comes to equipment-specific parts, I am considering using the model number as the primary identifier, followed by a detailed description of the part (e.g. JS2100 - Output Shaft - Manufacturer's Part Number). However, it is worth noting that our mechanics are more familiar with equipment locations rather than model numbers. Is this a common practice in other companies? I am open to suggestions and insights on how to improve our equipment and inventory descriptions for more efficient maintenance management.

When it comes to specifying materials, it is important to use attributes to accurately define them. For example, when selecting a motor, certain essential attributes such as Motor Speed, Number of Poles, Frame Size, Insulation Class, RPM, and Duty must be considered to determine the right motor for the application. These attributes can be customized based on specific operating conditions and requirements. It is crucial to agree upon these attributes to ensure the motor performs optimally in its intended environment.

When cataloguing materials, it is crucial to begin descriptions with a primary identifier such as "SHAFT". By entering "SHAFT*" in the search bar, you can easily access a list of all shaft-related items. For a more comprehensive search, use "*SHAFT*" to include shaft sleeve, shaft key, shaft seal, and more. To further specify the part, you can add a qualifier like "SHAFT,OUTPUT" - make sure to separate with a comma and no spaces. Include the Manufacturer only if necessary: "SHAFT,OUTPUT,MFR". Add the manufacturer's part number too: "SHAFT,OUTPUT,MFR,PART NUMBER". Additional details like model number and relevant data for purchasing can be included in the long text. Mechanics can locate materials through Bill of Material assemblies without the need for location descriptors. A BOM assembly will be created for the JS2100 model and linked to the appropriate equipment items. Below is an excerpt from our material cataloguing document.

When naming equipment, it is important to establish a structured system rather than using the operators' informal terms to avoid confusion. Not all operators may refer to equipment the same way. Therefore, starting the description with a clear primary identifier, such as "PUMP," is crucial. Follow this with the model number and size details to provide a comprehensive description. In our facility, we use the Functional Location to indicate the process location, emphasizing the importance of consistent naming conventions to facilitate user searches. For example, we begin with the location tag number followed by the official location description, like "P4903 REACTOR 28 OUTER COOLER PUMP." It is essential to consider how users will search for equipment to ensure easy navigation within the facility.

Thank you David and VinMan for your invaluable assistance. I recently inherited a system that was not well-planned and it's been great to learn from your approach. I must admit, some of the current descriptions are causing me quite the headache as I try to decipher them. I can definitely see the benefits of utilizing your system for specific machine parts. Just to clarify, is the naming convention for a shaft sleeve SLEEVE,SHAFT,... and for a shaft key KEY,SHAFT,..., etc.? Upon reflecting on your feedback regarding equipment naming, I have decided to make changes and provide additional training for our operators and mechanics. Your advice has been greatly appreciated.

When structuring your database, it's essential to include fields for crucial identifiers such as manufacturer, part number, and catalog number. Incorporating these details directly into the description can enhance organization and streamline searchability. For instance, a more effective example would be to list parts as "SHAFT, KEY" and "SHAFT, SLEEVE," with the main description preceding the modifier. This approach not only improves clarity but also facilitates easier product identification and retrieval.

Your idea of using model numbers followed by a detailed part description seems effective for maintaining an organized inventory list. However, since your mechanics are more familiar with equipment locations, perhaps you could incorporate this into your naming system. One possibility could be labeling each piece of equipment with its model number and then tagging the parts specific to that model directly, while also indicating the location. For instance, "JS2100 - Pump 1 - Output Shaft - Manufacturer's Part Number." This way, you maintain your model-based organization while also providing the location-based information your mechanics are used to. It might be a learning curve initially, but it could result in a more efficient identification process in the long run.

I think your approach of using common operator language in naming equipment is a good start. It's vital to have the information easily understood by the people who'll be using it daily. However, it's crucial to remember that those operators may change over time and the new ones might not understand the previous naming convention, so it's worth considering a more universal approach too. Regarding your proposition on the pump model parts, using the model number as the primary identifier coupled with a detailed description of the part seems a good idea. It can ensure standardization of spare parts across similar equipment and can minimize your spare parts inventory. That being said, you could create an easily accessible reference guide that connects operators' common names with the universal or technical names. This could mirror the familiarity while enhancing the universal nature of your inventory system. Remember, whichever method you choose, consistent training and reinforcement are essential to ensure all staff are on board.

It sounds like you're on the right track by considering both operator familiarity and standardized naming conventions! In my experience, a hybrid approach can work well—why not use a dual system where the equipment name includes the location alongside the model number? For instance, you could use something like "Line1-JS2100 - Output Shaft" for easier recognition on the floor. Also, consider adding a quick reference guide or visual aids that tie model numbers to their locations which may help bridge the gap between your mechanics’ familiarity with parts and their understanding of model numbers. This way, you're keeping things standardized while still respecting the operators' insights on equipment terminology. Good luck with your CMMS implementation!

It sounds like you're on the right track with using a combination of model numbers and detailed descriptions for your equipment parts. Standardizing your naming conventions, like you've begun with bearings, can really help streamline communication, especially if you include key details that your mechanics can easily recognize. One strategy that worked for us was integrating location identifiers into the descriptions—so instead of just "JS2100 - Output Shaft," you might consider "Plant1 - JS2100 - Output Shaft." This way, it retains that important location context while still being standardized. Additionally, consider creating a simple reference guide that maps model numbers to common operational names; it could smooth the transition for your team. It’s all about making information accessible and intuitive!
