As promised above in this week's First Thoughts column, here is a great selection of original responses to our August Logistics Challenge. Many more next week. If you can't wait, you can find additional submissions, most quite good, here in the Feedback section at the bottom of the page.
Feedback of the Week on August Logistics Challenge:
Great Challenge! I wish the whole project was mine.
Without seeing inbound raw material and finished goods delivery patterns, it's difficult to derive a total solution but certainly as you are indicating, there are issues with material planning and with marketing.
For the former:
If each plant is going to do custom mixing, then they need to be accountable for their own BOMs. It sounds like it's a free for all with ingredient transfers becoming so common place that they've lost sight of the associated costs. (This is a typical scenario. Slow and steady degradation of procedures without any checks in place. Most expensive phrase in business - "We've always done it that way".)
Secondly, there are 26 plants. Surely they don't all need to duplicate production. They can each distribute their core non valued added product but specialized mixing and use of certain ingredients needs to be allocated to specific plants using a demand analysis. There would be less production down time, and higher volumes of each ingredient, allowing far more cost effective shipping practices, inbound and out. It would require a new logistics model but it's just math. There is a "best solution". The cost of longer transits would more than be made up through efficiency gains.
Often when there are high frequencies of repeat LTL shipments, there are opportunities for dedicated milk runs which take advantage of truckload rates plus a stop charge verses single skid LTL rates. This also increases operational consistency leading to better materials practices.
For the latter (marketing):
It sounds like there needs to be some education about the cost of the word "guarantee". LTL service comes with none. Even if it has a consistently high on time percentage, there is no guarantee. If the customer says "I have to have it", you are forced to use a higher priced option to achieve the exact same result. A little more communication between trading partners about specific needs is often enough to eliminate or drastically reduce premium freight costs. Getting even more proactive, negotiate larger but less frequent orders, perhaps also taking advantage of dedicated milk runs. Premium freight is a derivative of poor planning and communication, not a conscious service choice. If your delivery parameters are such that they are causing all of the above activity, then your supply chain risk level is as perilous as your costs.
It's impossible to say without knowing the ratio between valid and non-valid transportation activity but based on the descriptions, I don’t think it's a stretch to imply a potential reduction of 25 to 30%. There is always math to be done around the 'transportation verses inventory trade off' but there is a lot of low hanging fruit in this case. More importantly, the result of turning your supply chain into a performing asset versus an out of control cost center is... priceless!

I found your article very interesting and see the dilemma you described: "Overall spend is high, so it must be the rates". Far from true. Companies need to have competitive rates, no question. But this task should be done later, once the network is understood completely. There are better things to start with.
So, in your article you bring up a few insights:
• Each shipment was sent on its own without consolidation
Let's start with the order process: Few plants simply produce without an order or a related production plan which is based on customer demand. While different industries have different order patterns, i.e. dynamic (daily, hourly) or more static (weekly, quarterly), there usually is either a plan or a dependable forecast of what might happen tomorrow, next week etc.
• One way to gather that information is to have the plants enter the shipping requirement into a common system. Portal applications usually work well and can be implemented quickly.
The next step would be to convert the orders into manageable loads:
• Transportation Management systems, SAAS applications have basic functionality and can combine shipments and do basic optimizations. This would ensure that there are not three different LTL orders shipped to the same destination on the same day. It would provide a lower cost and - if the person entering the shipment was honest about the need-in-plant date - even ensure delivery at the right time.
Now actual load and shipment tenders to the carriers can be created. But which carriers do I use? Are my rates good?
• I always believe that it is best to start with the existing carriers and once patterns emerge, maybe after 2 months or so, to put lanes out to bid to see what the market is doing.
In my experience, controlling the freight payment process is controlling the network. Few companies check whether the service invoiced was actually provided as described:
• Did the trucker actually use a tarp/flatbed/under deck space?
But how will you get the plants to play along? Budgets are often held de-centralized at the plants, allowing local decisions to interfere with the common good of the company. I found that third party service providers, Lead Logistics Provider or Control Tower operations can provide the necessary "glue" to put network together, manage carriers and costs.
But more successful companies have centralized their logistics and have put into place checks and balances, even consequences for non-adherence: Requirements are understood for the entire company, authorities are distributed adequately and rate negotiations are done with the entire network in mind.
There is certainly more to it and I could write about this all day.
What an interesting idea for a column!
As you hint, there are probably several ideas that might be rolled out over time.
The first might be to simply force the use of expedited air service for interplant transfers to be authorized by someone high enough in the organization (say the President) that only the desperate will ask. That in itself will severely reduce the airfreight premium.
The next may be to build in a charge for expedited interplant transfers for every customer order that requires it, thereby making these orders less profitable. This makes the additional cost very visible, and may lead to different behaviours in sales and in logistics - "how can we avoid that extra charge?"
Then maybe get back with carriers to see what can be done about making time-definite road services available. This builds confidence that interplant products will arrive as planned, but will also pay dividends on customer deliveries.
This short term plan might knock as much as 10% off the freight bill, through demand destruction and the use of land at 70% of the air rate for interplant transfers.
Then consider a network approach to interplant transfers. Given the frequent materials shipments, maybe a regional warehouse for low volume ingredients, with a mandate fulfill orders overnight to plants within the region. By concentrating low volume ingredients across several demand points, inventory can be better managed. By fulfilling from a regional hub, costs and availability of slow moving ingredients can be optimized.
Then maybe there is something to be done about the manufacturing strategy and scheduling. Pepsi has won awards for the use of regional mixing centres for low volumes, supplemented by local distribution for high volumes. Perhaps there are opportunities in the way the production is scheduled today, like differentiating between fast movers (shipped next day) and make-to-order (shipped next week). Perhaps regional custom mix freight can be shared with inbound raw materials replenishment.
Network design projects can be extremely lucrative, but require fairly sophisticated financial models to evaluate. My opinion would be there is probably another 10% of the freight bill available. This also allows the company to see their logistics costs very clearly, to understand the different costs-to-serve various channels and markets. Finally, customers will be very receptive to a promise of delivery, rather than a promise of shipment.
I'll be interested to see what others suggest.
There are a lot opportunities at this client it seems!
step I would take is to make sure the shipping managers did not have to
memorize every lane's rate and transit time by mode. Most humans cannot
memorize all that detail and then execute the "optimal" decision based
on all other shipments going on at the same time. Especially when the
environment is dynamic which in this case it is (build to order with 3
day lead time from order to shipment). Moving to a TMS would allow this
company to make better shipping decisions based on the destination, lead
time and volume / weight of shipments.
we tackle the upstream and likely more challenging issues next, we can
begin to reduce the amount of ingredients that are moving between
plants. Better forecasts allow plants to more likely have the
ingredients they need to satisfy production. Plant sourcing decision
improvement allows the right plant to make the product given where the
customer is located (shipping costs based on transit time), which plant
has the raw materials to satisfy the production, and what transfers may
need to occur. All of that is optimized based on least cost and meeting
the service levels. Lastly, if plants are regularly running low on
ingredients, there may be an issue with re-order points, supplier
service levels, or timely consumption reporting when used in production.
The roadmap for these changes is dependent on their current processes
and systems. So my next step would be further exploration.
First off, good for you for having the President's attention... my guess is the Transportation Manager did not for probably a host of reasons.
Regarding your case study, I have more questions than answers but I'll take the bait and offer "the first solution that comes to my mind" (your fork truck driver was a wise person and I absolutely love to tap "unofficial leaders" like that).
I'm going to admit my own bias that freight is almost always a greater % of total logistics costs than inventory carrying. That bias influences my recommendation as you will read below.
I recommend your client consider regionalizing distribution of raw materials to DC's that are within one day of mixing plants. I suggest they use contracted 3rd party public warehouses on variable cost basis so they don't incur huge capital to make the change. I would, however, spend some capital (or go cloud) to implement a WMS that would give them total inventory visibility even where inventory is deployed at contracted warehouses. The WMS should be sophisticated enough to give the economic order quantities to help manage the inventory replenishment process and not let it get out of control.
I would also implement a TMS on a transaction cost basis that would give them electronic, rule-based tendering and carrier performance management tools. I'd make sure the TMS had a good BI tool to give them real-time transportation data verses relying on a post audit/freight pay service for the data. Start measuring on-time delivery in addition to on-time ship.
I would set about to educate the culture on Lean principles. Clearly, the feedback the Transportation Manager received from the Branch Manager wreaks of a culture that does not embrace process flow. It also sounds like the transportation supervisors are that in name only as well. They probably wear many hat which is ok but freight spend is huge so managing that needs to be higher on their priority list.
Lastly, and again admitting my own bias, the single most brilliant thing they can do is to hire me as Vice President of Supply Chain to implement all of the above and save them millions of dollars.
Prepare a weekly report of the freight differential of actual versus planned costs. This would be by shipping location, and show the air freight costs and the LTL costs for the shipments of the week, ranked highest to lowest. Copies would be sent to the President, the Plant Managers, Production Managers, and Shipping Managers for each shipping location.
Q: What company is by far and away the largest 3PL in terms of US revenues?
