Is This a Six Sigma, Lean or Kaizen Project?

This is a familiar question that is often addressed by organizations. In fact, it is the wrong question. These concepts are nothing more than tools in your management toolbox. You don’t fix a watch with a hammer, and you get the same results when you deploy Six Sigma, Lean and Kaizen incorrectly. The fact is,…

Applying Lean Manufacturing to Six Sigma

There are continuing questions about the relationship between Lean manufacturing and Six Sigma techniques. This relationship has been expressed as follows: Stretch the process applying Lean techniques Solve the problems of deviation from the standards Ensure maintenance of the improved status using Six Sigma techniques However, if the system and processes are too poor, stretching…

A Lean Approach to Staffing Brings Optimal Performance

Organizations are often challenged with managing seemingly unmanageable work volumes with available staff. At times, staff may feel overwhelmed with high work volumes, or underutilized during periods of low work volumes. When a management team finds itself confronting these issues, team members may ask the following questions: How can staff respond to internal and external…

Get a Feel for Lean: Explore Application Opportunities

Extensive training and a thorough understanding of complex analytical tools are required to successfully perform traditional Six Sigma projects. Although this careful and methodical evaluation is an invaluable problem solving technique, traditional Six Sigma projects can be time consuming and must be carefully selected. Lean projects, on the other hand, are different. Lean is intuitive,…

Lean First…or Six Sigma?

When initiating process improvement the question often arises which to pursue first – Lean, Agile, Six Sigma or a combination of these tools. There have been case studies surrounding the order of choice – or whether Lean and Six Sigma complement each other at all. Many Six Sigma experts have spent significant time living and…

Value in Focusing Lean Six Sigma on Distribution System

Value at the point of production does not necessarily translate into value at the point of consumption. Likewise, Lean Six Sigma initiatives focused on the factory floor do not ensure that the end user is receiving that value. As a product moves through the distribution system there are many factors that can diminish its value….

Lean at Work…: From Factory Floor to Operating Room

Until relatively recently, many quality professionals considered the term “Lean” to only be applicable to the manufacturing giants of industry. Lean, first created as a part of the Toyota Production System, is an operational approach and methodology embraced by world-class companies around the globe. With proven results, Lean has made its way into non-manufacturing industries,…

Streamlining Coast Guard’s Accounts Payable Process

The local senior leadership of the U.S. Coast Guard Finance Center was confronted by the problem of maintaining high levels of service in its accounts payable (AP) process in the face of increasing process complexity. Compounding the issue was the fact that the center’s information technology (IT) systems had been modified to accommodate the growing…

Lean Taking Root: It Depends on Culture and Leadership

Will Lean practices take root within an organization and lead to transformational change? That depends on the organization’s culture and the role that leadership plays. Within a traditionally structured organization, ideas and direction flow primarily from top to bottom, or executive to worker level. This may be expedient in some ways, but it also can…

Fitting the Right Belts for Design for Lean Six Sigma

Every Lean Six Sigma deployment leader must eventually confront the critical decision of how the various Belt roles should be allocated and deployed throughout the organization. Lean Six Sigma has existed for more than 10 years now in a variety of manufacturing, service and distribution environments, and through trial and error fairly standard niches have…

Lean Six Sigma Improves New Hire Reimbursement Process

Roy Madsen, Senior Advisor to the CFO and Lean Six Sigma Champion at the Office of Comptroller of the Currency (OCC), said his organization had long encountered a classic catch-22: “From 5 to 10 percent of our workforce each year are people hired into entry-level examiner positions, the majority who have to move to a…

Improve Software-Development Productivity with Lean

To survive in today’s competitive software-development market, organizations need to build their capabilities around delivering the best service within customer-stipulated time frames and costs. Increasing productivity – the rate of output per amount of input – is the factor most likely to give an organization an edge over others. Many software-development organizations have realized the…

Cause-and-effect Diagrams and Lean for Service Processes

Lean improvement of service processes is somewhat different from Lean improvement of manufacturing processes. Efficiency is usually a measure of speed and cost and Lean improvement in efficiency is achieved by eliminating waste in time or resources. Effectiveness is usually a measure of quality and the overall objectives of the enterprise in that regard. If…

When Implementing Lean, Live the Methods You Teach

Practitioners must think “lean” from the beginning when they are starting an initiative in a certain area. Part of their job is to transfer the Lean philosophy. To do this effectively, they must be role models who live Lean all day, all night, all the time – this will earn them credibility. If not, a…

Lean: Relentless Pursuit of Product Value and No Waste

Lean, like other process improvement methodologies, is based on the big idea from the 1980s that a business is composed of a series of processes, a value stream, that delivers value to its customers. A process is Lean if it uses only the absolute minimum of resources (material, machines and labor) to add value to…

Lean Banking: It Is Not Always Just Single-Piece Flow

“Let the process flow.” “Let the customer pull.” This is what is written in manufacturing books about making processes Lean. But it is not always that simple. Consider this banking example. A customer arrives at a bank branch: He enters, is welcomed by an employee and offered a cup of coffee. He explains his interest…

Lean Manufacturing: Adapting as Important as Adopting

Lean is a wonderful experience when deployed properly and can be a nightmare when it is not. When properly deployed, a company has productive and relatively happy employees, increased efficiency, on-time deliveries and all sorts of other desirable outcomes. When it is not deployed properly, a company can have angry customers, frustrated employees, late deliveries,…

Learning to Recognize Process Waste in Financial Services

One of the biggest challenges for Six Sigma practitioners in financial services is developing the ability to recognize waste. Imagine an “overnight pack” entering Bank One’s wholesale lockbox process for processing remittance payments. By the time it has been through every step, up and down the elevators, back and forth between departments, it would have…
