Don't get me wrong, I think lean is a strategy from which virtually every company can benefit. It is a great way to gain control over processes and improve quality while reducing costs. Throughout my career, I helped many companies implement lean and have seen some great benefits as a result.
The problem I'm having is that lean is being oversold to business. Consultants and practitioners are promoting lean as if it is the cure for all of a company's problems. I have gotten into many discussions over the years with people who are disappointed when leaders don't place lean at the very top of the company's priorities.
Part of the Picture
Lean can be a valuable part of the company's overall strategy. The critical word here is part. There are other elements of a corporate strategy that are just as - if not more - important depending on the company's individual circumstances. In the most simple example, a company can be highly successful with lean but go out of business if it is not offering products or services that people want to buy.
However strategic planning is specifically conducted, the process should generally include an analysis of the four high-level objectives that are necessary for success: (1) People/Leadership Development; (2) Process Improvement; (3) Product/Service Development; and (4) Market Development. There are times when one or more of these areas will need extra focus, but unless all are analyzed on a regular basis, the ability to understand which areas are in need of attention is limited.
Strategic planning requires an assessment of the company's situation to understand where the current barriers are to achieving success at any given time. The barriers can be weaknesses that interfere with success, or opportunities that can help the company grow and improve performance, but they will become evident during the process of understanding and evaluating the four high-level objectives. The analysis helps senior leaders understand where the company's focus (in terms of investment and resources) needs to be in the coming one to three years (or beyond, depending on the normal planning horizon).
Let's Maintain Perspective
The point here is not to oversell the benefits of lean, and to understand why executives don't necessarily put it at the top of the company's priorities. As an initiative, lean can directly support the process improvement objective and indirectly aid product/service development, but to truly help an organization succeed, it is important to understand that it may be end up being something other than the top priority.
