Reliability and Maintenance Management (RMM) - The frontline of maintenance
Many Reliability and Maintenance improvement initiatives fail to deliver sustainable (and continuously improving) results in improved safety, manufacturing throughput, and costs. There are many reasons for this, but the lack of engaged, visible, and caring plant leadership is the most common of them.
Taking regular walks to visit the frontline of maintenance, or Gemba walks, is an excellent way for a leader to demonstrate engagement. Such walks take management to the front lines showing that they are an engaged, visible and caring leader and also enables them to learn first-hand what improvement opportunities exist. You are visible and you show that you care. This is key to successfully improving your maintenance organizations’ performance and delivering continuously better results.
Gemba, sometimes spelled Genba, is Japanese for “where things happen,” or "the real place." It can be anything from an actual crime scene to the context of an RMM organization, where planners, front-line leaders, coordinators, engineers, operators, crafts people cand storeroom employees close to the manufacturing floor make things happen. They are the ones who will execute your initiatives, such as preventive maintenance, work management, stores organization including, delivery and “kitting” of parts and material, and many more improvements. If they do not execute your initiatives, then all you have is a plan.
As leaders, we are often pressed for time, but carving time to engage with the frontline is crucial for success. Remember - improving reliability and maintenance performance is “90%” about people and processes, so it is important that you are visible and available.
If you organize and schedule frontline walks well, you will find that it does not have to take much time. You will also find it interesting and rewarding when you see the appreciation and improvements.
I suggest the following steps for your frontline walks initiative:
- Organize and plan
- Observe and learn
- Ask questions, meet face to face
- Act and follow up
Depending on the size of the Maintenance organization, the plant manager might do a frontline walk once a quarter per production area. Operations and Maintenance managers might do the walk together once a month in their respective areas. Supervisors should do it weekly.
Set up an improvement activity to focus on for each walk. Do not include things already on your meeting agendas. No need for duplication.
It is very beneficial if you have done an assessment of improvement opportunities and a plan on how to close the gap between how good you are now to how good you can become in three to five years.
If you have done that and have identified the gaps you need to close, it will serve as a setup- and focus guide, for each walk. This will most likely include the following areas to improve upon.
- Lubrication practices
- Precision maintenance practices
- Basic inspections and predictive technology
- Work management
- Storeroom management
There can be other areas, but as good maintenance always requires—the basics must be executed well before you will be in a position to move towards excellence. Most plants I work with need to focus on the areas mentioned above.
In a small plant the walk could include several improvement areas, while it will be necessary to select one or two focus areas in a bigger plant. Try to limit the “Observe and learn” and the “Ask questions, meet face to face” to 30 minutes each. These steps can be done the same day or on different days.
When you organize and plan your frontline walks, it is very important to share why and how you will do them with those involved.
If you, as a plant, maintenance or operations manager, have a habit to be visible on the manufacturing floor and often talk with the frontline people, the walks will help organize your visits towards defined and selected improvement areas. For frontline leaders this is, of course, not much of an issue as you work closely with your people daily. If you, as a manager have kept a distance to the frontline organization it may be a welcome change. If your visibility was limited in the past, your appearance may be associated with trouble. This will change when people understand why and what the Gemba walks mean to the whole organization.
3.Observe and learn
Before you do “Ask questions, meet face to face” walks—visit the chosen production area you will observe and study the equipment so you can ask the right questions. The first time you do this walk preparing questions might take a bit more time.
If you chose lubrication practices in one area you should look at:
- Blown out seals indicating too much grease and poor seals.
- Use of tools to measure grease volume on grease guns.
- Clean tools and grease points.
- Oil levels in gears, pumps etc.
- Keep oil level indicators clean to see levels and colour of oil.
- Right oil levels marked.
- Lubricant type marked with a symbol.
- Lubrication stores clean and organized.
- Air breathers/filters installed where needed. Change in colour?
- Long grease lines for manual greasing.
If you chose Precision maintenance practices in one area you should look at:
- Jacking bolts installed for precision alignment.
- Jacking bolts backed off and not pushing on alignment object.
- More than three shims used for alignment.
- Beat marks on equipment feet.
- Vibrating fans and high-speed equipment.
- Filters for mechanical seals and hydraulic fluids.
Other operating practices you should look at include if your redundant pumps are running equal time per each schedule and who is responsible for shifting the pumps according to that schedule.

4. Ask questions, meet face to face
After “Observe and learn”, you have the material to be well prepared to meet face to face and ask questions.
Meet with the people in production who are responsible for various areas like lubrication, for example. Ask open-ended questions such as: “I saw a lot of grease pushed out from the drive side bearing of the fan pump, what can we do about that?” The answer might be: “That seal was gone a long time ago, so we need to purge out the water to save the bearing, we have asked to have it replaced many times. We also have new lubricators who have not been trained and think the more grease the better. We have also asked to get grease meters to put on the grease guns, so we know how much grease each point gets.”
Other possible questions: “What would you like to spend more or less time on?”
For the lubrication program, “What is the most important thing to improve upon?”
The discussion will teach you a lot. But perhaps more importantly is the motivation you create by being engaged, visible, and caring as a leader. This goal will only be reached if you continue these walks.
5. Act and follow up
Be prepared for suspicion. Many people have seen new improvement initiatives come and go and may not be impressed. You have to prove this will be a continuous practice.
During the frontline walks it is important to take notes and pictures. This will take less and less time as it becomes routine. It is important to inform your people what you decided to act upon. If you decided to get the equipment lubricators needed and train all lubricators, for example, then you might want to change the damaged seals. It is equally important to share what you decided against, and why.
When well-organized, the five steps of the frontline walks will take a manager in a big plant about an hour per quarter/area. For operations and maintenance managers walking together it might take an hour a month per area, and front-line leaders much less time per week. I am sure you will find it worth the time as your Safety, reliability and cost will improve.

Are Any of These Elements Holding Back Your Maintenance Improvement Strategy? A look at five common trouble areas that derail reliability
Over the last 15 plus years, I have watched many organizations both flounder and succeed at maintenance and reliability improvement. I have witnessed many spend considerable effort without creating the return on investment that they promised their stakeholders. In my opinion, there are 5 very common reasons that these experiences demonstrated success, or failure.
