What Sandpaper Will You Use? – Part One
What to Use to Get the Most of Your Demand-Driven Changes

Demand-driven manufacturing leaders are always refining their tools and tactics to ensure they’re spending their time wisely. This blog marks the first in a three-part series about using the tools of TOC, Six Sigma and Lean to help manufacturing leaders gain the most benefit from their demand-driven transformation.

Three in One

TOC, Lean, and Six-Sigma should all be part of the continuous improvement (CI) journey at your company – and knowing which tools are right for the job will help you realize your CI goals faster. And even though these three methodologies are not the end all, be all of continuous improvement, they offer proven frameworks and tool sets that are very effective at improving organizations.

During this discussion, I want to explain how the methodologies of TOC, Lean, and Six-Sigma work like sandpaper. TOC is the coarse, Lean is the medium, and Six-Sigma is the fine-grit sandpaper. The company is the board –or piece of wood in a particular state of roughness – and you have to know which paper to use, based on the state of the board. At Synchrono, we use all of these methodologies together—leveraging the right tools at the right time —and apply them strategically in our customers’ demand-driven transformation.

TOC to Start

I have never seen a more effective approach when you are just starting out than TOC. The methodology is all about understanding the entirety of the system and based on that, knowing where the leverage points are in the organization that, if affected, will bring about a rapid change to the entire system. It recognizes the interconnectedness and cause and effect of organizations, their people, resources, processes, and most important, policies.

When you first start a continuous improvement journey, the opportunities for improvement are great. They are everywhere within the organization and once the workers in the system have approval and the tools to change the system; they will do so with great effort. However, if we want to get the most out of these efforts, we need to focus these improvement efforts on the constraints/ leverage points of the organization to yield global results, not just localized effects. Said differently, we need to focus on the areas inhibiting enterprise performance, and I have not seen a more effective approach at doing this – and doing this quickly – than the TOC methodology.

Next time, I’ll talk about how to use TOC to pinpoint the changes necessary to get the most out of your continuous improvement efforts. Then, I’ll address the role of kaizen events and drill down into how Six Sigma – the finest grit of sandpaper – can refine your process change and ensure that each moving part works harmoniously together. Like many jobs, having the right tools makes all the difference in the world. The right methodologies, along with ongoing refinement, will steer your demand-driven environment towards embodying the best in form and function.

Where to Start Your Lean Journey

There’s one sure-fire way to tell when someone has lived in Minneapolis long enough to be called a Minnesotan. No, it doesn’t involve rooting for the Vikings, though that helps. It’s when they can find their way around The Mall of America without a directory.

Built in 1992, The Mall of America still ranks as the largest in the US with more than 500 stores, just about every kind of restaurant you can imagine, and last but not least, the 7-acre Nickelodeon theme park. For the visitor, the first stop is one of the many directories, whether it’s to figure out the shortest path to your goal or to make plans for how you will spend the next several hours.

Planning Your Lean Journey

Like visitors to the Mall of America, manufacturers looking to apply Lean principles start in the same place. Their “directory” is the 8 types of waste identified in Lean:
- Overproduction – Manufacturing more than is needed to fill customer orders.
- Waiting – Time spent waiting for the resources or materials needed to complete the next step.
- Inventory – Excess material and WIP.
- Transportation – Unnecessary movement of material through the facility/supply chain.
- Over-processing – Taking more processing steps than are necessary.
- Motion – Unnecessary movement of people.
- Defects – Defective materials, WIP and finished goods. Can also include defects caused by obsolescence or expiration of materials.
- Workforce – Failure to leverage the skills, talent and knowledge of your workforce.
Electronic kanban (eKanban) are an easy way to tackle every one of these categories of waste. Here are a couple of recently published resources that can help you get started:

How SyncKanban Addresses the 8 Types of Waste in Lean

SyncKanban Gets Lean on Scrap

Measuring Your Progress

Shoppers at the mall might measure their progress by checking items off their shopping list. Lean practitioners need to be a little more sophisticated. Each of these types of waste has at least one metric associated with it. While there isn’t always a clear 1:1 correlation, the chart below shows just some of the most common metrics impacted when improvements are made.

For more details on several of these metrics as well as additional metrics you may find useful on your Lean journey, refer to our online and downloadable Metrics for Action Guide.

Remember, you don’t need to measure every one of these metrics. Instead, determine which of them are most meaningful to your organization and focus your efforts. You’ll also want to be sure you choose metrics for which you have systems that can deliver good data. It makes no sense to try to go Lean, only to add a bunch of manual steps just to get the data you need.

If your ERP systems are holding you back because they aren’t giving you the data you need, we may be able to help. Almost all of our customers implement SyncManufacturing, synchronized production planning, scheduling and execution software on top of their ERP systems. To learn more, download The Changing Role of ERP in Manufacturing.

The Lean Journey Often Starts with Inventory

For many manufacturers, it makes sense to start by focusing on excess inventory. If you remember the rocks and water analogy from your Lean training, you’ll recall that many manufacturers use excess inventory to cover all matter of issues.

Here are a few case studies of manufacturers who leveraged SyncKanban to help reduce excess inventory:

Dynisco: In 12 months, this instrumentation manufacturer saved almost $1B during implementation by right-sizing their inventory with SyncKanban.

Orbital ATK: Aerospace & Defense manufacturer replaces 16 replenishment systems with SyncKanban to reduce inventory levels by 30% and scrap by 90%.

Manufacturers Get Lean on Scrap with eKanban Software

Manufacturers Get Lean on Scrap with eKanban Software

The method of Lean Manufacturing is based on the relentless elimination of waste in manufacturing and ongoing continuous process improvement. For many, material scrap is an expensive form of waste; costing more than the material itself. Consider that hiding behind every dollar of scrapped inventory are several more dollars lost in storage, productivity, customer satisfaction and potential revenue…MORE

It’s Time: Manufacturers Need to Cut Ties with MRP and Spreadsheets

A few years ago, Aberdeen Group did a study that showed that 63% of “best in class” manufacturers still used spreadsheets for planning. With percentages this high, it’s probably safe to say that there is a lack of trust in planning tools like ERP and MRP even in the best-run companies.

Of course, spreadsheets come with their own set of issues. You may have a certain amount of confidence in the spreadsheets you’ve created, but what about those from your colleagues? Do you know what formulas they use to arrive at their conclusions? Where did they get their data? If the creator of the spreadsheet goes on vacation or worse – leaves the company – how quickly could a new planner take over their role using the existing planning tools and methodologies?

Spreadsheets also contain computational and data errors. Forbes published an article quoting “various studies” that put the rate of significant errors at 88%. Though no specific studies were named, you probably don’t need that extra level of validation. You know the spreadsheets you use have errors in them. Otherwise, why would you still be having such a hard time synchronizing inventory and production to demand?

The Problem Lies in the Basis of the Plan

Actually, spreadsheets are pretty powerful tools, even with the occasional error that creeps in. Likewise, MRP and ERP usually do exactly what they are supposed to do. They create time-phased material requirements and production plans based on the parameters entered into the system: forecasts, reorder points, capacity and so on. The calculations are so basic that even the most rudimentary software applications get them right.

The problem lies in the basis for the plans themselves. At the root of all production and material requirements plans lies the forecast, often generated by the sales or marketing department. Even when calculations are based on an analysis of historical data, it’s still a forecast. And, as we are all painfully aware, there is no such thing as an “accurate forecast.”

Not trusting what they’ve been handed, inventory and production planners use spreadsheets to massage the forecast data before it is entered into the system. Some of these comments might sound familiar:

“We always see a bump in demand for these items in June, so we need to increase production now.”

“I know sales has a quota on this new product, but I think they’re being overly optimistic. If we cut the requirements by about 10%, we can deal with it later if they actually manage to reach their quota.”

“I read in the news that there may be shortages of this material. Let’s order extra now so we can stay ahead of the problem.”

At the end of the day, the forecast is still a forecast, even with the wisdom of inventory and production planners added in. Unfortunately, the new forecast may not represent reality any better than the original forecast received from sales, and ERP and MRP have no choice but to translate those erroneous assumptions into equally flawed material requirements and production plans. In turn, these flawed plans translate into all sorts of issues: expediting orders, late nights, increased overtime, missed deadlines, angry salespeople, angrier customers, inflated inventory levels, blown budgets, tense meetings in the executive conference room and bland food diets to prevent your indigestion from turning into a full-blown ulcer.

Grounding Planning in Reality

Since there is no such thing as a crystal ball that shows future demand, manufacturers who want to break free from this vicious cycle need to replace forecast-based planning with reality-based planning. In short, ditch ERP, MRP and spreadsheets (at least for replenishment and production planning) once and for all.

The only way to do that is to synchronize production and material requirements to actual demand and supply as well as what is happening on the factory floor. It’s called Demand-Driven Manufacturing, and here’s a quick definition:

Demand–Driven Manufacturing is a method of manufacturing where production is based on actual customer orders (demand) rather than a forecast. This process is accelerated by technology that automates, digitizes data and connects every function within the demand-driven organization and to every layer of the supply chain.

We created an entire platform called the Synchrono® Demand-Driven Manufacturing Platform that sits on top of your current ERP system and synchronizes all elements of production to demand and supply. There is no need to rip out your current ERP or MRP applications; our tools use actual customer demand, supply status and the reality of the factory floor to synchronize production. The methods used, such as eKanban, Lean Six Sigma, Theory of Constraints, are no doubt familiar to you.

If this is the first time you’ve taken a close look at Demand-Driven Manufacturing, we have several resources which can help you build a solid foundation for discussions with others in your organization:

Manufacturing Metrics that Actually Matter (The Ones We Rely On)

Part one of a multi-part series to help you measure your production efforts wisely

LNS Research blogger Mark Davidson said, “When it comes to metrics, it’s often said that what gets measured gets done.”

I have found this to be true when working with many different manufacturers. Mark also writes: “Metrics that have the attention of business and manufacturing leaders tend to be those that get measured and improved upon by their employee teams.”

I agree– measurements do drive behavior. But are employees being rewarded for metrics that do not in turn reward demand-driven flow and the customer signal (both real and imagined)?

In this set of blog posts, I want to discuss the different kinds of metrics we’re obsessed with as supply chain leaders and why the modern lean, demand-driven production manager needs to adjust or abolish some “old school” metrics altogether. But before we get into specifics, let me set up some of the environmental factors that have contributed to the current climate of “KPIs above all.”

The People’s KPIs?

Over the years, there has been a lot more attention placed upon measurements. Key Performance Indicators (KPIs) are meant to clarify how we measure what we measure and provide an underpinning for people in production to see how well they are working toward their goals.

However, the amount of responsibility and work content for most workers has grown at the same time, and left these workers with little ability to truly affect the measurements that are prevalent in today’s manufacturing environment. This erodes their ability to continue to complete the tasks that are being measured.

Even when there is a specific measurement that makes sense for the supply chain, it may not be within the individual’s ability to affect all of the measurements that they are responsible for during production. There may be contradicting measurements, and there may be cases where during one part of the month the measurement is religiously followed, while during other parts of the month, they are breaking the rules because some other measurement has become a crisis.

Count the cost

In the last 20 years, the emphasis on reducing cost has also had a profound effect on the ability of workers, supervisors and managers to focus on results. I have seen countless improvement projects implemented. In the more aggressive organizations, I have seen leaders make budgetary and staffing cuts based on the cost/benefit analysis of a project. Perhaps this isn’t so bad, but at the same time, I see little or no verification of the results and actual performance. This state of affairs has us trying to do more work with fewer people, under increased pressure with fewer results.

Metrics for Action

In the next few posts, I would like to break down the operational metrics you’ll need to empower your workforce to get results—not to just behave according to flavor-of-the-month measurements. These Metrics for Action are not intended for overall business analysis. Instead, the intent here is to cut through the clutter of the all too often, and all too many, contradicting measurements and focus on the metrics that are going to provide insight to drive action. Action to improve flow, manage constraints, direct continuous improvement efforts and more. The goal is to provide real clarity around the elements that drive organizational excellence and enhance demand-driven results.

Before we begin, here’s why we should

Assuming is the worst: Most measurements used in manufacturing are derivatives of some other objective or assumption about the nature of manufacturing. These assumptions seemed important at the time because manufacturing software and information systems didn’t support a direct link between performance and measurement. They were very important “back in the day” because they provided a framework for decision-making in a time when there were few data elements to support the decision process. This was way better than the alternative of no decisions!

Put your money where your metrics are: If you trace these measurements to cash flow, you will find some interesting conflicts. In the past, having all the relevant data for making decisions created a great deal of measurements that act as a surrogate to actual performance. These types of measurements have been around for a long time. They have become so common that they are not even considered as obsolete, but as “the way we conduct business.”

Even with today’s incredible ability to collect and contextualize data, these seemingly monolithic measurements are still being used. To test if your Manufacturing KPIs are obsolete, check to see how the measurements can be tied back into cash flow. If there is no direct link to cash in, cash out, inventory or operating expense, then your measurement may be an assumed measurement.

Customer Centric If there is no data in your company’s systems measuring what your customers are actually buying directly, then you’re working with a derivative measurement. Derivative measurements were used to simplify the planning process because the units purchased by the customer were hard to track or hard to translate into workflow. Today, synchronized, demand-driven systems can capture your customer order information across the entire production process—from order to supplier to inventory to shipment. You have all of the data points you need—but you may be still tracking derivative side-effects rather than meaningful metrics from force of habit.

The unfortunate reality is that most manufacturing measurements are the results of learned behavior, hidden behind several layers of assumptions that are obsolete or counterproductive in today’s manufacturing company. Stay with me through our metrics journey to see how you can laser-in on the metrics that really matter—to you, and to your customers.

The Future of the Organization is On Your Shoulders

Imagine this: You’re in a high-level planning meeting with senior leadership, when the CEO and CFO issue a clear mandate: Get inventory levels under control. The VP of Sales, never being one to hold back an opinion, steps in to argue that the organization needs to become more competitive if it’s to survive. Right now, your promised lead times are the longest in the industry – even longer considering how often your promised delivery dates are not met. Lowering inventory levels will only make things worse!

The VP of Sales claims that, if service levels don’t improve, sales’ only recourse is going to be to offer deeper discounts even though margins are already paper thin. The CFO and the CEO declare, in no uncertain terms, that playing the pricing game is not an option.

The meeting ended with everyone looking at you, clearly expecting you to come up with a way to lower inventory levels, decrease lead times and improve on-time deliveries. Basically, the future of the organization is riding on your shoulders. No problem, right?

Right!

eKanban Saves the Day

Since senior leadership expects you to be Batman or Wonder Woman, it’s a good thing you’ve got a utility belt called Demand-Driven Manufacturing. On this belt are a number of utilities that can help manufacturers achieve what may seem like impossible (and conflicting) goals.

In today’s post, I want to focus on one of the easiest utilities to master: eKanban. Since eKanban also targets one of manufacturing’s biggest issues (excess inventory), this is where many manufacturing superheroes begin. (There are some other rather nifty tools on this utility belt, like constraints management, but it makes sense for a lot of manufacturing managers to tackle improvements in stages.)

As most manufacturers already know, Kanban is the visual inventory replenishment system that is fundamental to pull (demand-driven) manufacturing. When production is pulled through the factory based on actual orders, inventory levels go down because no more than is needed is produced.

eKanban is a more powerful version of Kanban as the visual signals are electronic instead of physical cards. Electronic signals can be sent upstream faster, and there are no cards to lose. It’s also easier to learn to use an eKanban system because there are typically fewer steps involved. One manufacturer we worked with reduced the number of steps in their replenishment process from 66 down to 6 by replacing their manual Kanban system with SyncKanban eKanban software from Synchrono^®.

SyncKanban further magnifies the benefit of eKanban by making the system even more responsive to actual demand. Whereas many eKanban systems still require the operator to set the number of Kanban signals in the system, SyncKanban automatically recalculates the optimal number of signals based on actual demand. If there are more orders than anticipated, the number of eKanban signals in the system goes up in real-time. If there are fewer orders, the number of eKanban signals goes down, ensuring no more is produced than is necessary to fill orders.

eKanban: Your Multi-Purpose Utility

While you’re delivering a big Kapow! to excess inventory, don’t be afraid to tackle other key performance metrics at the same time. eKanban can also help here because eKanban signals pull production through the facility based on actual orders. When work center C needs more of a subassembly built at work center B, a signal is sent for replenishment to workstation B. With work at every work center focused on only what is needed, queue times decrease and flow increases. On time deliveries often increase as well with SyncKanban because of the application’s ability to match flow to demand in real time.

One manufacturer was able to reduce inventory by 55% while also reducing leads times from 12 weeks to 2. Read the full story. Another manufacturer’s implementation of SyncKanban landed them on Supply and Demand Chain Executive’s 2017 list of 100 great supply chain projects. Learn more.

Be a Superhero in a Hurry

Clark Kent changed into Superman with a quick hop into a phone booth. If only it were that easy! Not only are phone booths in short supply these days, production management is a bit more complicated than donning a red and blue onesie and a cape.

Nevertheless, SyncKanban eKanban software is one of the easiest tools to implement, and many of our customers start seeing the positive impact of eKanban on inventory levels in less than 90 days. eKanban doesn’t even require the manufacturer to replace their ERP system. You can learn more about this in our paper The Changing Role of ERP in Manufacturing.

We have a ton of material about implementing eKanban on our website. One of the most popular is the white paper series on eKanban that starts with Gaining Control: Exploring Push v Pull. If you’re already convinced eKanban is the right tool to use and it’s just a matter of how to get started, you’ll enjoy the series of guests posts from one of our customers that starts with Real-World Advice for Getting Started on eKanban. You can also watch a demo of SyncKanban or request a free trial version on our website so you can explore the tool first hand.
