Strategy vs. Tactics: Was There Really a Change in Thinking?

Guest post by Howard W. Coleman, Principal, MCA Associates
I was pleased and honored to recently present at TUG Connects 2012: The Future of Inventory & Supply Chain Management—The Change in Thinking.
Despite the fact that I noticed a few “furrowed brows” in the audience during my session, I was encouraged by the number of requests for my white papers as a follow-up. Also Tim Earnest of Earnest & Associates (an Infor channel partner) shared with me that one attendee proclaimed it was “the best presentation I heard at the event.” I can only be subjective, but am gratified none-the-less.
So why the “furrowed brows?”
The stated objective of the presentation was to:
- Challenge the conventional wisdom of our inventory and supply chain practices.
- Provide some insight and understanding into what others are doing.
- Overcome the hesitation to change.
- Accelerate the adoption of some new “DNA” in our supply chain practices.
In trying to improve our practices, we can either add more complexity or we can change our reality. Unless our reality is changed, there’s no reason to believe that our hard work will produce a different/better result. So that’s the initial “call to action”—to consider strategy and more radical change.
Back to the 90s
Historically, distributors relied on forecasts to drive inventory planning and ordering and to use safety stock to mitigate the variability in forecasts and lead times. These are really tactics as opposed to a better strategy. Overlooked at the time were just-in-time (JIT) concepts. Somehow we didn’t take JIT seriously enough in distribution, or maybe didn’t fully understand its major premise of using simple demand signals from customers and passing those up and down the supply chain. We continued our practice of pushing inventory to our stocking locations, primarily based on forecasts. (In informal polls, generally only a few companies know what their level of forecast accuracy really is.) Most companies never considered the concept of pulling inventory into stocking locations based on the customer’s buy signal—reacting to the drum beat of the customer and letting that drum beat pace the rest of the supply chain. Rather, we have accepted “incremental improvement” versus radical change.
A picture worth a 1,000 words
This picture is meant to illustrate the inventory in your supply chain under different paradigms. On the right, inventory peaks are much lower and the intervals between the peaks are shorter, meaning average inventory is substantially less. Because replenishment cycles occur more often, actual demand drives your replenishment needs and there’s less reliance on forecasts, less exposure to forecast variances, and therefore less safety stock needed.
The future practices
Consider PULL similar to JIT. Think of it this way—the grocer replaces stock on the shelves as product is actually bought by the customer (customer’s buy signal). As product is sold, a replacement is pulled throughout the supply chain and we get a “continuous flow of product” and an “increase in the velocity of the supply chain.”
Target inventory levels
If we could establish target inventory levels for products (see our white paper for a full explanation), we could monitor our inventory planning activities by describing it visually; a “business intelligence approach,” or as the folks at Infor call it—“changing the way work is done.”
The effects on supplier relationships
So if we can visualize the information, why shouldn’t we be able to communicate it to suppliers? Maybe suppliers should think differently too. This is already occurring in vendor managed inventory (VMI) relationships where companies share actual consumption data. What if you could help your supplier smooth out their production, maybe help reduce their work-in-process, and decrease their lead times? The result would foster a more continuous flow of product and would increase the velocity of the supply chain. In supplier relationships, a win-win occurs only when there are aligned interests.
Finally…
Look at Pull as a business intelligence system and a way to support “changing the way work is done”—a strategy for the future of distribution inventory and supply chain management, execution, and supplier collaboration.
Your call to action
What should you be doing right now about your supply chain strategy, your collaboration with suppliers, and your competitive advantage? How can you Pull your supply chain into the future? I welcome your thoughts and comments.
