The Pitfalls of Lean Warehousing Programs and How to Avoid Them

Published by Kane Is Able on May 30, 2019

Lean warehousing quality improvement programs have driven billions of dollars’ worth of value across corporate supply chains. They are the road map to faster, better and cheaper. But, if you’re not careful, these programs can become weighed down with bureaucracy, adding time and cost to your quality improvement efforts.

Lean Program Pitfalls

lean-warehousingToday, “Lean” is an industry, with university curricula, formal certification programs, and thousands of consultants offering “Lean in a box.”

The management approach that seeks to eliminate waste has become institutionalized, with all the attendant bureaucracy – meetings, paperwork, reporting and budgets. The danger here is that, instead of having Lean work for us, we become slaves to the Lean bureaucracy. As a result, productivity plummets and costs mount without an acceptable ROI.

Lean warehousing programs are not inherently inefficient. It’s all in the implementation. We simply need to examine our own Lean Six Sigma programs to ensure that the management of such efforts doesn’t interfere with getting the work done.

This article reviews some ways in which the management of Lean programs can get in the way.

Bloated Bureaucracy

Meetings, Lean charters, complicated reporting requirements…. These and other administrative trappings can serve to make continuous improvement more of a homework assignment than an opportunity to make things better. The danger here is that someone with a good idea may be reluctant to put it forward.

The Lean program manager asked the group to first develop a clearly worded “charter” for a formal Lean project. Hours were spent writing and re-writing the charter according to a format dictated by the manager. The team became frustrated and their enthusiasm waned.

A properly defined charter is important to keep everyone aligned, but let’s not get nuts here. Capture the problem statement, scope and goal, then get on with the project and make adjustments along the way.

Unnecessary Lean Projects

lean-warehousingAs corporate dollars are allocated to Lean programs, the pressure mounts to show an ROI. Consequently, tactical assignments that could be handled with a meeting or a few phone calls get put forward as formal Lean projects in order to justify a budget spend.

Not every opportunity is a Lean Six Sigma project!

In an article for Forbes Magazine, Steve Denning wrote about the COO of one company who held plant managers accountable for running a certain number of “learning events.” According to Denning, “it became slash-and-burn Lean, with no sustainability and no continuous improvement…old school outcomes with a forced carrot and stick motivation.”

It may sound counter-intuitive, but the best Lean projects are often reactive, versus proactive. They are initiated to solve an identified problem. If, for example, a manager launches a lean program involving cross docking to cut down on inventory costs, there should be a reason to do so first. When staff is pressured to go out and find problems to feed the Lean project pipeline, that’s like walking around the house with a hammer looking for something to bang, versus recognizing a problem (a crooked picture on the wall) and fixing it.

Poor Training

Lean training should be practical and meaningful for all levels, including the people who do the work. Be careful of taking an overly academic approach. Leave the theories and complicated models to the program managers.

Six Sigma tools are a good example. There are hundreds available, from the “5 Why” root cause methodology to regression analysis. Zero in on the ones that work best for your company and focus your training on the use of these specific tools. Keep it practical and keep it simple. Your lean process should be a lean process.

lean-warehousingWhen designing a Lean training program, be careful not to over-emphasize the engineering side (the analysis tools) at the expense of the cultural side (facilitation, team problem solving, accountability). In the words of management guru Peter Drucker, “Culture eats strategy for breakfast.”

 

 

Unsustainable Program

Enthusiasm over Lean programs tends to peak in the early stages after the low-hanging fruit is picked, with impressive results. Where many companies fail with Lean logistics programs is sustaining them and continuing to drive ROI after the big-value ideas peter out.

The core tool used to drive Six Sigma projects is DMAIC (Define, Measure, Analyze, Improve, Control). But companies too often ignore the control piece – the heart of continuous improvement.  As Shigeo Shingo, Toyota production system expert, said “It’s only the last turn of the bolt that tightens it – the rest is just movement.”

Summing Up: Leaning Out Lean Programs

Keys to Success for Lean Program Implementation

  • Define how Lean and Six Sigma programs will work for your organization. Don’t implement a generic version of Lean. Adapt the program as needed to fit your company’s objectives, structure and culture.

  • Keep the training simple. Overly academic or complicated training can turn off the operations staff, who will ultimately determine the program’s success.

  • Pick the right initiatives to develop as formal projects. Many may not require the formality and structure of Six Sigma methods.

  • Keep meetings to a minimum. And keep them short.

  • Manage group sizes. If you’ve got 15-20 people on a project, that’s too many. The more people, the less productive you’ll be. Staff can be involved without being a part of the core team.

  • Define a timeline. Open-ended deadlines invite wasted time and delay closure.

  • Lean out your tool set. Pick just a handful that you’ll use regularly and revolve your training around these.

  • Involve customers. Ultimately, everything you do is designed to drive customer value. Inviting customer input directs your efforts toward the most value-driving activities.

The Lean movement began as a grass roots effort to eliminate waste and improve quality.

Simple, unpretentious and important.

To continue realizing the enormous benefits that Lean efforts have delivered to supply chains, we need to keep Lean warehousing program implementation simple, with a focus on the people, the culture, and getting the work done to deliver value to the business.
