RIPHave you ever heard the old saying “Too much of a good thing is not a good thing”?   Probably… but what does that have to do with zombies?  Stick around and I will get back to that, but first I want to talk about Lean Management.  The guiding principle behind Lean is the elimination of waste of all kinds, whether that is excess inventory, inefficient production processes, poor quality or any of the rest of the 7 deadly wastes of lean.  At the tools, training and implementation of Lean is focused on the understanding that ANYTHING that does not increase value to the customer is a waste and must be eliminated.  From a relatively high level review of Lean Management this is readily understandable and easily applied to all aspects of the business.  Notice that I have consistently used the term Lean Management rather than Lean Manufacturing, Lean Operations or any of the other common names.  I do that deliberately because most of the different names seem to suggest that Lean is a production tool but in reality Lean techniques and processes can be applied to any process in any part of any organization.  That means that Lean is applicable not only in manufacturing but also in logistics, front or back office, logistics, sales or any other part of an organization.  The key to how and where Lean Management is used though still boils down to identifying what is waste and what is required.  If something is truly waste then removing it is clearly “a good idea”.  But what happens if we start eliminating things that are necessary?  Maybe that is not such a good idea… but, of course we would never do that.  If something is necessary then we would obviously never choose to eliminate it.  Right?

In its simplest terms waste is anything that does not add value to the customer but how do you identify what adds value?  Some of these are obvious but even for the ones that are obvious, can you go too far?  Eliminating scrap loss is obviously a good thing and no reworking or changing of scrap is going to add value to the customer.  The problem occurs when the cost of eliminating scrap becomes greater than the cost of accepting scrap.  Now reducing scrap loss (a good thing) is costing the company money, increasing their costs and eventually increasing the customers cost (not a good thing).  This is an obvious example where too much of a good thing is not a good thing.  Want another example?  How about forecasting?  One of the absolutes about forecasting is that they are wrong.  That is OK as any planner or forecaster is far more interested in how wrong it is rather than the actual forecast.  This forecast errors leads to all kinds of waste such as excess safety stock, incorrect inventory levels, incorrect lead times, etc.  Therefore, reducing the forecast error must be a “good thing”.  But reducing error creates cost.  That is OK so long as the increased cost is less than the increased savings.  But once the cost is higher than the savings it is “not a good thing” and a certain level of forecast error becomes acceptable.

So now we have the idea of “Too much of a good thing is not a good thing” clear in our heads, right.  Still does not explain about zombies though.  Essentially every process in a company directly affects capacity and flexibility, and those that do not affect it directly will do so indirectly.  Also, both capacity and flexibility represent a cost to the organization.  As we implement Lean Management and start eliminating various forms of waste, many of these changes will have the side effect of decreasing both capacity and flexibility as well.  Some of the projects may even be directly aimed at reducing capacity as a way to reduce costs (after all, excess capacity is a cost and anything excess must be a waste).  Since all these things are reducing costs they must be increasing value to the customer and therefore must be “a good thing”.  Right?  Not necessarily.  The problem is that by reducing capacity and flexibility you also reduce the organizations ability to respond to changes in product demand.  If you are currently running at close to 100% of capacity and an opportunity to take on a new customer to significantly increase business comes along…will you be able to accept the new business without affecting your current customers?  Or will increasing your capacity to allow you to accept the new business require so much time and expense that the customer goes elsewhere?  Many companies have spent the last several years systematically reducing their capacity to the point that they no longer have any flexibility left.  Yet new business is the only way to grow a company, whether it is from an existing customer or a new customer.  One of the things that organizations share with plants and trees is that they are either growing or they are dying.  Plants cannot stay the same and neither can organizations.    Lean Management is a good thing but too much Lean can be a bad thing.  Many organizations have leaned themselves to the point that they are effectively dead already but do not know it yet.  Any major economic shock and they will be out of business due to their lack of flexibility.  In effect they are Zombie Companies…dead but still moving, which brings me back to the original question…Are you working for a zombie company?

One last point, this phenomenon may partially explain the rather jerky recover from the latest economic downturn.  Everyone was expecting a recovery but it seemed to have a lot of trouble getting any traction.  Maybe enough companies were having trouble increasing their production due to minimal available capacity and flexibility that opportunities were being missed and delayed which created problems in trying to get the economy up and running smoothly again.

Considering introducing a Lean Management program? Already have one implemented?
