De-Mystifying Lean Six Sigma for Purchasing Professionals

Many supply chain and purchasing professionals are intimidated by
Lean Six Sigma
(LSS) and its proponents. Relax. It is just a disciplined approach to
problem solving. LSS uses many tools that have been around for years; in
many cases the tools have just been cleverly repackaged by consultants.
Decisions are data-based, disciplined and plodding. Without top-down
commitment, LSS is doomed to fail. Make sure you secure this executive
commitment, and better yet make participation a strong criterion for
individual
performance reviews
(raises). Projects should be selected by ROI (Return on Investment) and
since much time and teams are required for a project, they must return
or save at least $300,000 to qualify as a full blown LSS project.
Supply chain and purchasing professionals must be involved in
sourcing the LSS consultant. Experience is critical and a proven track
record of project success essential. Get references and insist on
examples of work. Use a fixed hourly rate and make sure all developed
training and projects remain your property. You can try to make the
contract performance-based but many LSS firms will not agree to this.
Make the goal to be self-sufficient internally within two years with all
LSS training and projects.
Some LSS projects that have been done in purchasing and the supply chain are:
Inventory cost,
part obsolescence prevention, leadtime reduction, backlogs, unexpected
orders, customer service internal and external, cost of schedule
changes, transaction flows, cost of return product, and supply chain
optimization. Many of these involve process mapping which is a type of
flow chart that illustrates how things are done and identifies areas of
strength or weakness.
LSS is not the only tool that can be used by supply management
professionals for improvement. In my experience LSS should be used when
the potential savings is great and you have some good data to analyze.
If you do not have good data the LSS project will take even longer. If
data is sparse, the Lean approach is much preferred which is highly
visual, intuitive and does not require as much data.
Always Lean a process before you use LSS. By this I mean
eliminate any redundant steps in the process that can be easily
eliminated first. Reduce the number of variables in the process. Try to
understand the
voice of the customer
(VOC) clearly before your start process improvement. Remember if the
customer does not really care or value a process step; ask yourself,
“Why are we doing it?”
Finally use kaizens for straightforward less complicated
projects. The kaizen approach is usually done by the work team using the
process and strives to eliminate waste in the process. The new kaizen
improved process should then be quickly implemented. Supply chain and
purchasing professionals must take the leadership role in LSS, Lean and
kaizens. In my professional experience, the rewards of these approaches
can be astounding. They do however require a measured and disciplined
approach, and a commitment to not giving up!
