Walk down: It's Not Just Exercise Any More

Running in soxs
Do you know how many assets you have to maintain? Do you know what equipment types they are? If you need a part do you know enough about the equipment to place the order without a trip to see it? Do you have a perfect General Ledger that does not list assets that no longer exist?
If you answered no to any of these questions then you may need to go on a walk down.
Walk down is the process step that starts the path toward more reliable assets. During the walk down you collect things like equipment name plate data, equipment type, components, configuration, parts, as well as other details required for a good maintenance plan.
The data collected during the walk down will be used to build things like:
The hierarchy of equipment
The predictive maintenance database
The Bill of Materials or BOM for each asset It will facilitate discussions during the equipment criticality step of the process. Specifically when we dive into the question of redundancies and use. It will also be used by planners when they plan and accountants when the account for the assets on the books.
With all of these uses it becomes clear that  it is worth the effort to collect equipment data. So how do we get started? The way I see it you have two options. The first and undoubtably the best is to dedicate teams to each area of he facility and provide them with a walk down tool or database to collect the data. If you use this methodology you get better results faster than the alternative, however it comes at a cost. But hey like they always say, there is good, fast and cheap but you can only pick two. The second option is to collect as you go with a data collection form assigned to each work order the first time it is issued against the system of assets in an area. The form is completed and collected for entry into the CMMS and other databases. In this approach you spread out and some what lower the cost but at the the sake of speed. In most organizations time is money and unreliability never takes a break so in the end the best way is to dedicate resources and build quickly and then update future field changes with the form. If you have questions about databases or how long it should take a team to collect the data then shoot me an email or give me a call and we can discuss you facility and our past experiences.
Are you happy with your criticality or do you need to go for a walk?

  1. I have done this,but it doesn't have to be all one way,a combination of efforts! I had operations who know the equipment and where it is better than anybody, record equipment data on all assets they operate and are vital to their part of the process!The facilities part was done by that branch of maintenance doing pm's by adding a data form for each pm no matter where it was.Operations maintenance did their part on all their supportive assets and looked for items that might have been missed by each of the other,the data input was done by data input people at a much lower cost than by the planner or other maintenace people .also some of it was done by light duty people recovering from health issues but still being productive.It took like 6 months but it was well covered and accuret and cost effective.New assets need to be done as part of the project documentation,including RCM!
