What is the Standard?: How Lessons Learned in the Military Can Make a Difference in Business.

What is the standard? 

It may seem simple, but I challenge you to ask that question about a process that is causing friction in your organization. 

Was the answer as simple as the question? 

Let’s take it one step further. If there is a standard, is it understood by everyone involved in the process? 

It is my firm belief that that simple question can alleviate many problems in day-to-day operations. 

Is There a Standard? 

There I was, a young officer in the United States Army sitting in my Platoon office trying to make sense of our latest maintenance status reports. Only 40% of our fleet was operational two weeks ago, but now suddenly 85% of our vehicles are ready for a field training exercise that is coming up in a few weeks, and I assured everyone that we were “good-to-go”.

The day we were supposed to head out for training, half of my vehicles either didn’t start or had a fault that was severe enough to prevent us from taking it to the training area. This left us scrambling to figure out how to transport my platoon plus our equipment with half of the operational vehicles required. 

This obviously didn’t go over well with the boss. 

Oh, and did I mention we missed our planned movement time by THREE hours?

A Noticeable Trend

Since I had taken over the platoon, our maintenance readiness had become inconsistent with no discernable causes to justify the fluctuation. 

The maintenance readiness reports were getting filled out. However, the information contained with varied significantly depending on which of my team members had completed them.

Many of reports didn’t have the proper signatures from their first-line supervisor. They also failed to document the necessary details required to address issues. And if a team member didn’t put their name on the sheet, I had no idea who to ask about the equipment’s status. 

Identifying Where Standards are Needed

After getting ripped apart in the maintenance meeting for another week as our next field exercise approached, I finally decided I had had enough of these maintenance issues. I sat down to map out the entire maintenance process with a counterpart to find our deficiencies… and there were many! 

First and foremost, there was no standard operating procedure (SOP) for the maintenance process, only for the required checks and preventive maintenance of the equipment. 

Secondly, we didn’t have our vehicles assigned to anyone. It was first-come-first-serve on preventive maintenance. 

We also had no one responsible for overseeing the maintenance program to ensure that all maintenance activities were being performed properly, get status updates, or check the reports to ensure they were filled out correctly. 

In addition, many of our team members could identify issues but they couldn’t describe it in a way that made sense to someone with minimal mechanical knowledge, nor did they know they needed that amount of detail. 

Implementing a Standard

After we realized the issues, there were three easy actions that solved nearly all our problems. 

First, we assigned different pieces of equipment to different sections of our team so there would never be a question on who is responsible. We also ensured that each section had every type of equipment under its area of responsibility to ensure that every individual in that section would get experience performing preventative maintenance on all our equipment. Most importantly, equipment assignments were posted on our maintenance board in our office and distributed electronically every week to ensure all team members knew what vehicles they were assigned. 

Second, we assigned a maintenance manager to oversee the maintenance program within our team. We tasked the maintenance manager with submitting an SOP for the entire process as well as a process map to visually demonstrate all the steps within the process for approval. When there were deficiencies with our maintenance program, I didn’t have to run around looking for answers anymore. I simply asked the maintenance manager. 

Lastly, each section of the team would go through training to ensure they understood the standard. They would also demonstrate understanding of the process by doing a walk-through, creating a process map, or a combination of the two that would be evaluated by myself or the maintenance manager every quarter. 

Similarities Between Military and Business

At this point you may be saying to yourself, “This all sounds great, but how does this relate to the business world?” 

The reality is that, in the military, we did many of the same things that people do in business. We may have used different verbiage to describe it and key performance indicators (KPIs) to assess it, but the process map that we created in the scenario above is very similar to a value stream map (VSM) that you may create for your process. 

We identified “True North” and examined the requirements we needed to meet within our operating environment. 

A current state map was created that helped us determine our bottlenecks and constraints within the maintenance program. 

We created a detailed SOP that not only explained the process but also described the expectations for how the program would run in the future. 

We created metrics, otherwise known as KPIs, that would help us understand if our maintenance program was operating as it should. We also added standard escalation procedures to help team members decide when to escalate maintenance concerns to different levels of management. 

We even executed process validation and process sustainability steps to keep the maintenance program up to standard. 

We included our maintenance managers in all of our operations planning meetings. Our daily leadership meetings were more effective because the uncertainties of our maintenance statuses were able to be addressed immediately by the manager.

What Standards can do for You

Within six months of implementation, we were had achievd over 80% equipment readiness – the highest in our Company and more than double our initial 40%. 

We were getting our maintenance issues resolved more quickly because our maintenance reports were consistent and detailed enough to create action items for our operators. 

The military is predicated on maintaining readiness of people, equipment, and organizations to react to whatever threat presents itself at any given moment. 

Sounds like operating in today’s business environment, doesn’t it? 

Unexpected market demand, supply chain disruptions, an inconsistent labor market are all threats that can impact your company’s readiness, and without the proper standards in place, you may be struggling to react to these challenges.

RFID: Is it the Right Solution for Your Business?

Way back in 2013, my team was tasked with implementing RFID for the systemic transfer of all raw components from the warehouse to the production lines. With ~10,000 kanbans delivered each day across 3 shifts, this “cutting-edge” solution would allow us to transfer parts 1 kanban at a time instead of 1 pallet at a time ushering in a new epoch of inventory control. 

That was the plan at least.

Fast forward to November 2017. I’ve just been promoted to the department group leader, and my first task was to increase RFID penetration from an anemic 25% to 100% across the entire plant. The company had even given me a full-time resource to help address the issue.

But why? Why had it taken 4 years for RFID based Kanban delivery to be implemented across only 25% of all value streams?

To understand that requires that you understand a bit about how RFID works in relation to a WMS system.

How Does RFID Work with a WMS?

WMS transactions are traditionally executed using RF barcode scanners. In a typical warehouse, associates sign into the WMS system using an RF scanner and, using a standardized barcode label applied to each unique SKU, scan and click their way through a series of screens to book, put-away, and issue material to the production lines.

This process requires associates to be trained on the use of both the WMS system and the RF scanner. They are also dependent on the WIFI signal. Any interruption in WIFI brings all warehouse related activities to an abrupt and grinding halt. 

In this system, new associates become a liability for inventory accuracy and WIFI a prerequisite to function.

Forget to press the last button on the scanner to confirm the order? Inventory is wrong. 

Lose WIFI signal in the middle of a transaction because you accidentally walked in a “dead zone”? Inventory is wrong.

Get a bad label with a barcode that can’t be scanned? You can manually enter the data, but if you accidentally “fat-finger” it… you guessed it, inventory is wrong.

RFID works by eliminating these weak points. Instead of inputting the information via an RF scanner, the information is “written” to the RFID tag and attached to the corresponding item.

These tags are then scanned using RFID readers or gates which are connected to the network via POE (power over ethernet) and programmed to do a specific task, i.e. move material from one bin to another, log a movement, issue parts to production, etc..

But contrary to what the salesman told you, RFID is not a miracle cure-all for all your inventory ailments. It has weak points of its own that must be mitigated to be successful. 

RFID Gates

For those unfamiliar, an RFID gate, sometimes called an RFID portal, automatically registers all passing RFID tags. When most people think of RFID, this is the scenario they have envisioned. 

RFID tags are seamlessly scanned, read, and processed as they pass through each gate within a facility. No muss, no fuss. Just slap on a tag and away you go. 

What could be easier?

Nothing… if it worked like this. 

Unfortunately, the reality of the situation is that RFID gates rarely ever read 100% of the tags passed through them. This becomes especially true if the tags are placed on or near metal. Based on my experience, a well-tuned RFID gate with tags applied to an appropriate medium will read ~95% of all tags passed.

To get read rates higher than 95%, again, in my experience, requires the addition of another gate to “catch” the tags that the 1st gate misses.

But wait, you say. 95% read rates sound pretty good. Can’t you manually correct the missing 5%?

And the answer is… it depends. 5% of what? 

In our case, 5% of 10,000 kanbans meant that we would need to troubleshoot ~500 inventory discrepancies per day or ~165 per shift with only 1 inventory control specialist. 

Anybody that has ever performed a cycle count can tell you that, in most cases, it would be impossible to count this many part numbers in a single shift every day.

Instead, inventory errors just pile up until either: A) the production line is shut down due to inventory-related issues forcing someone to finally investigate and correct them or B) the inventory is corrected at the annual year-end inventory.

Either way, someone eventually must manually adjust inventory levels and reset the system.

And here’s another fun fact: this process continuously repeats itself because the gates continue to miss passing RFID tags …

RFID Point-of-Use Readers

The other option is to employ point of use readers where the operator scans each RFID tag one-at-a-time using a reader mounted at the point-of-use to “fill” the kanban and then again once the parts are consumed to “empty” the kanban. 

In other words, before each kanban is delivered, the warehouse operator will remove the kanban card containing the RFID tag and hold it in front of the reader to scan it and then return it to the corresponding parts bin. 

There is even a light that will flash green if the scan processes properly and red if there is an error.

Sounds simple

What could possibly go wrong?

Well… a lot. 

It turns out that it is very difficult to get multiple people across multiple shifts and in multiple areas to do anything 100% correctly, 100% of the time.

People get tired of scanning kanbans one-at-a-time, so they hold 5 kanbans up and once. Unfortunately, the reader can’t process 5 kanbans at once so some just don’t get scanned. 

Or folks don’t feel like escalating a failed scan as indicated by the red light, so they just pass it along and keep going and leave the problem to fester. 

Or, they just plain ol’ forget to scan.

Experience has taught me one thing: if a process can be screwed up, someone will screw it up more than you think.

So, what happened?

So, as I mentioned when I took over as group leader, RFID had been a major thorn in our side for 4 years. The problems were simple, but permanent solutions weren’t easy to achieve.

We used point of use scanners, not gates. Almost all of our problems stemmed from kanbans not being scanned in the proper sequence. If we could train the logistics operators to scan the Kanban when they delivered parts and the production operator to scan the Kanban before they ordered parts, almost all our problems would be solved. 

We knew that both logistics and production operators weren’t scanning cards, but it was almost impossible to determine which operators were failing to scan. 

That was until we found a tool that could help provide the transparency we desperately needed…Tableau.

Tableau is a business analytics software that can create graphic interpretations of very large data sets.

Once we established a data flow out of SAP, our ERP system, and into a Tableau worksheet, we could then analyze it to see where the scans were being missed and have it automatically refreshed as often as the data was updated.

After this was understood, we created a daily shopfloor leadership meeting that consisted of supervisors from each of the production areas along with the warehouse to review the previous day’s results, create action items, and follow up on the previous day’s tasks.

Within a year, we had managed to keep errors to a manageable level and finally achieved 100% penetration of RFID for the delivery of all raw components! 

This turned out to be a boon for the logistics department. Because we now had RFID for all component deliveries, we were able to implement additional Industry 4.0 tools like Nexeed Transport Management, a software system that connects to SAP and uses the transfer order data to populate a tablet mounted to a tugger to direct the operator’s activities and allow them to confirm delivery of kanbans from the tablet – eliminating the need to scan the kanban for each delivery.

Now, if the operator could drive the tugger and knew where the markets were located, the tablet would direct them on everything else. This cut training time down from weeks to days and helped improve inventory accuracy by all but guaranteeing that scans were performed accurately.

So What’s the Verdict? 

Would I recommend RFID or not? 

Of course, I would. 

RFID allows warehouse operators to conduct more inventory transactions with the same or less labor input. This allows for improved inventory visibility and optimization.

However, like everything else in life, it comes at a cost. If you’re planning to implement RFID, it should be part of a long-term vision that takes advantage of the improved inventory transparency and accompanied with a commitment to the resources necessary for its successful implementation.

Otherwise, you are setting yourself and your team up for failure. 

If you’re interested in implementing RFID or contemplating if it’s the right solution for you, give us a call. We’d love to work with you and your management team to help plot your digitalization course and develop a roadmap for its successful implementation.
