PREFACE |
As logistics and supply chain professionals, we all have one thing in common. |
This commonality is that time is a scarce resource, one that must be treated as |
a treasured commodity. This means that we must choose wisely when deciding |
what books to read or what avenues to pursue for professional development. |
With any luck, when we do invest our time in reading an industry book, we |
will walk away with one or two “golden nuggets” that can help us with our day- |
to-day responsibilities and challenges. |
As the authors of |
Lean Six Sigma Logistics |
, we certainly kept the above in |
mind as we developed the framework for this book. To begin, we continuously |
asked ourselves whether a certain topic or theme was relevant to today’s logis- |
tics and supply chain practitioner. We continuously asked ourselves whether |
each point passed the “so what?” test. |
Consequently, we spent significant time up front developing the framework |
for the book. Using the serene background of Benson Lake in Eastern Ontario, |
Canada, we devised what we believe to be the key drivers for all logistics |
processes. This was no easy task. First of all, we must consider the two authors: |
one practical-thinking academic and one academic-thinking practitioner. Many |
times, we debated theory versus practicality and, oddly enough, many times the |
academic argued for practicality and the practitioner argued for rigor of theory! |
What lesson did we learn from this? The first was that theory relates directly |
to strategy. The second lesson is that practicality relates to tactical realities. To |
be sure though, we recognized that strategy and tactics are both required to |
achieve anything of significance. We must know what we want to accomplish |
and we must understand how to accomplish it! |
A majority of our discussion surrounded the topic of “flow.” Not flow from |
an inventory point of view, but rather the flow of the book itself. We continu- |
xi |
ously reminded ourselves that readers must be able to see the book as a whole, |
such that by the end they will say, “I see it, I get it!” And, therefore, the |
Logistics Bridge Model was born. |
The Logistics Bridge Model is a compass and map. It will help us to set |
a strategic destination and direct us on the operational journey. It is not a step- |
by-step “how-to” guide, but rather a path for critical thinking. In our opinions, |
it is critical thinking that is required in logistics and supply chain management |
today. We need to be able to look at operations differently. We need to under- |
stand what value is and what waste is. We need to leverage value and eliminate |
waste. That is the primary purpose of this book. |
In all sincerity, we appreciate your valuable time and we hope this book |
will help you to achieve your professional goals and organizational objectives. |
As well, we hope you will embrace the Logistics Bridge Model and enhance |
your ability to look at your supply chain with a critical eye and vision for |
improvement. |
