I have identified myself as a “reformed” lean Six Sigma Master Black Belt. Some will see this as an affront to lean and Six Sigma. I want to assure you that there are many things to like about lean and Six Sigma. The issue at hand is that a better solution is available that can help organizations achieve more robust performance improvement.
A couple of issues to address are the tools-based approach and the lack of change in thinking in the management and design of work found in lean Six Sigma. Lean and Six Sigma programs tend to be tools-based, where the aim seems to be for vendors to make money on tools training and not focusing on the change in thinking that must accompany it. This is a missed opportunity for sustainable and profound change.
When I first listened to W. Edwards Deming during one of his seminars, he talked to the audience about a way of thinking to manage a business (originally his “14 Points for Management” and “The Deadly Diseases,” and later “The System of Profound Knowledge”). He would never reference total quality management (TQM) or any other label for his thinking. Along came Taiichi Ohno and the industrial tourists that labeled this thinking “lean”—again, not a label that Ohno would reference. Total quality managment, lean, and Six Sigma all came with a ready-made tool box that could teach your manufacturing company to be just as effective as the manufacturing companies of Japan.
The second issue was that the thinking about the design and management of work that Deming and Ohno wanted us to understand never “took” in most organizations. The tools-based approaches of lean Six Sigma, and TQM pushed out much of the needed change in thinking. And executives pushed down these approaches to projects, processes, and the front line so that even when improvements occurred, they were soon undone by management thinking that had never changed. Or the efforts were to save money, and became too narrowly focused and suboptimized the system, generating either negative or no real savings in the service industry.
About five years ago, I ran across the work of John Seddon. His book, Freedom from Command and Control (Productivity Press, 2005), really started to put the pieces together for me. Four items stood out in his thinking:
Let’s discuss why these are important distinctions.
Demand provides the greatest leverage for improvement. Whenever an organization looks for performance improvement, management is wrongly focused. For example, in a call center everything is prescribed from management by how many phone calls, how long to handle a phone call, and what type of service level an organization wants to achieve. Conversely, Seddon discovered that customers calling had two types of demand: value demand (calls customers want to make) and failure demand (calls caused by a failure to do something or do something right for a customer). He found that failure demand in service organizations runs between 25 percent to 75 percent for the private service sector and as high as 90 percent in the public sector. Failure demand presented a huge opportunity to reduce costs and improve service to customers.
Costs are in the flow. Most service organizations measure cost and productivity because almost all managers have learned that management means managing activity and that activity equals costs. The management paradox is that costs are in flow—the number of transactions it takes a customer to get the service they request. The move to call center outsourcing to lower transaction costs can be countered by bringing call centers back in-house to satisfy customer demands (value or failure) at the first point of contact.
Failure demand is created by the design of work. The functional separation of work into specialties has been around for a long time, more than 100 years. Each function is forced to optimize its piece. However, optimizing the function (piece) doesn’t mean optimizing the whole system. The truth is that waste and suboptimization in duplication, hand-offs, delays, etc. manifests itself in failure demand. Failure demand is caused by the design of the work that has been designed into service organizations.
Standardization and technology create waste in service. Best practices, standardization, written procedures, scripts, technology, and automation are creating waste in service. The problem is that the variety of demand in service can not be addressed by these things. We standardize our work and then entrap it with technology. Workers receiving customer demands that don’t fit into their computer system are left looking stupid to the customer.
The concept of failure demand has gotten attention worldwide. The appeal is obvious—if we can get rid of failure demand, costs will decrease and service will improve. The problem presented as “reducing costs” is central (but wrong) to the command-and-control thinker. These people will set new targets for reducing failure demand in their organizations. My concern is that the appeal of failure demand will lead managers to miss real opportunities to improve. Already, copy cat consultants and IT providers are finding ways to eliminate failure demand through wrong thinking. This will lead to more bureaucracy and more inappropriate management behavior. So beware the snake-oil sales people.
The reality is that failure demand is only one of many things you need to understand to change to systems thinking or design. To rid an organization of failure demand you have to change the system, and to change the system you have to change the management thinking—there is no other way. The first step is difficult, but once taken, the benefits are deep. If or when managers understand that managing costs increases them, they will be open to understanding that managing to value is a better way. Pursuit of value allows managers to begin to learn about designing and managing their companies against customer demands… and costs will fall on their own.
