Panel Discussion: Managing the Complex Supply Chain

Monday, February 25th, 2008

Andrew ReeseIn this session, Andrew Reese hosted a discussion with Rob Wehrman from 3M, Anna Ross from Fonterra and Derek Nelson and David Simchi-Levi from ILOG. The session explored strategies for handling complex supply chain networks and touched on challenges like green logistics, risk management and rising transportation costs.

The session provided real insight into the complexity inherent in manufacturing and shipping on a global scale. Below are a few snippets from the discussion…

Fonterra: We use local offices (”mini-Fonterras”) around the world staffed with people with local knowledge to reduce the complexity of managing our global supply chain.

3M: Our biggest issue is data availability. Global infrastructures are expensive to manage and hard to standardize. You probably wouldn’t think of Post It Notes as complex, for example, but with over 300 colors (including at least 15 different shades of yellow!) to manufacture and deliver to markets worldwide, the humble Post It note is perhaps more complex than you might think!

Fonterra: We involve people in the modeling of the supply chain and explain to them how the data is processed. People are less likely to trust a new kid on the block who comes in with a fancy new solution that changes the way they’ve been managing their warehouse inventory for the last 20 years. Involving employees in the process helps everyone learn more about the product and fosters employee buy-in for improving these processes.

3M: Reducing complexity should not be an objective in itself, though. It’s likely that you can actually make more money by making your supply chain more complex. At the same time, there’s a certain amount of chaos built into the system. If left unchecked, a supply chain will always tend towards complexity because of the push towards local solutions that optimize local processes but fail to take into account the bigger picture.

Fonterra: We thrive on complexity. Staying on top of that supply chain is invigorating. If your supply chain isn’t complex, then you probably don’t have a very good supply chain or a competitive business model. Tools like those from ILOG are making the challenge of managing that increasing complexity easier and easier, so don’t be afraid of complexity. If you have the right tools to manage that complexity, you stand to generate considerable competitive advantage.

3M: Another import issue to take into account is the skill sets of your staff. Very few projects fail because of technical issues. People in your team who are able to identify the real problems behind your supply chain inefficiencies are invaluable. They need to be able to interpret your SCM data intelligently and use the system to identify appropriate adjustments. If your system reveals inefficiencies in shipping semi-finished goods between two different plants, it might suggest investing 60 million dollars or more to consolidate the production into a single plant to improve efficiency. However, if the underlying problem is in fact a simple issue of insufficient stock level management in one of the plants, you could save yourself a whole lot of money by digging a little deeper into the problem. Your staff need to be able to identify those failure modes and go beyond the surface data to investigate ways to improve the system in the most intelligent way.

Fonterra: We have a mix of older, more experienced supply chain planners and younger graduates with more up to date operations research and supply chain theor. The challenge is getting these two groups to work together effectively. We need to stay aware of new techniques, but also temper the enthusiasm of the younger generation with the reality of what is possible.

David Simchi-Levi: 10-15 years ago, supply chain management systems were designed for leading experts. These days they are aimed at business level users. It’s like purchasing a car. You don’t need to be an experienced mechanic to purchase a car these days. You’re concerned about issues of usability and practicality for your needs, but you don’t want to have to get under the hood with your oil can and wrench every time you want to go for a drive.

Fonterra: Green logistics is a huge issue for Fonterra. Every project we embark upon must include a carbon emissions impact study or it doesn’t get funded. Find out more in my session later today.

3M: One of our corporate values is to minimize our impact on the environment. We’ve not yet implemented carbon footprint evaluation into our supply chain, but we are following progress in this area carefully.

David Reese: To sum up, complexity is increasing. It’s unavoidable. Deal with it. When handled effectively, complexity can bring you significant competitive advantage. Think global when optimizing your supply chain activities. Technology itself can create unnecessary complexity if not managed correctly. Ensure you involve cross-functional and interdisciplinary teams in your SCM decisions.

David Simchi-Levi keynote: Countering the Risks of Offshoring and Lean Manufacturing

In this talk, David concentrated on the major trade-off facing supply chain operators - that between increasing plant capacity without increasing risk.

Redundancy

It’s difficult to build a forecast to build in risk. One way is to go through scenario (what-if) analysis. The problem here is that it can be difficult to predict every possible scenario and to determine which scenario will best fit your situation.

David suggests another approach - one borrowed from the financial sector - of working out the lowest cost portfolio and working in some redundancy to cover risk. The example used looks at the structure of the total cost function as you change the number of distribution centers. The graph looks something like a narrow-bottomed frying pan. The main point is that in a number of different scenarios, total cost does not change dramatically. Therefore you can pick the scenario with the maximum redundancy at this lower cost level. There may be a slight increase in total cost as a result of this, but risk is reduced substantially.

Network planning

Why is concentrating on the distribution network important?

  • Consumers are demanding this more and more
  • Europe now offers financial incentives for companies that cut carbon emissions
  • High carbon emissions means low SC efficiency
  • Future legislation is expected in US more in line with those in Europe

By applying network modeling, you can design a distribution network that satisfies customer demand yet minimizes carbon emissions. The key is to find the right trade-off between cost, service and carbon emissions.

Risk pooling

Inventory is can be stockpiled at different points in the supply chain for risk pooling. Overall the supply chain will be more efficient and maintain forecast accuracy.

In closing, David signaled the significant increase in the level of risk over the last few years. This is where supply chain planning can provide real value.

Work and play on day one of DIALOG

Sunday, February 24th, 2008

It was a long first day, but apart from a few lingering travel issues for some, everything seems to have got underway smoothly.

I had the pleasure of meeting with several speakers at this evening’s welcome cocktail and everyone is really excited to be participating in this groundbreaking event and looking forward to the next two days of sessions, panel discussions and networking opportunities.

Today was hard work for the DIALOG conference team, with lots of last minute preparations to complete and a few unexpected issues to deal with. I was very impressed with how everyone came together to resolve those issues and am proud to be part of such a great team of professionals.

There was still time for a bit of relaxation out on the golf course though (for some at least), made all the more pleasureable by the warm sunny Palm Springs weather. Below, in pictures, is a summary of this first day of DIALOG 08…

Three days to go! Some Bedside Reading

Thursday, February 21st, 2008

Three days to goIf you’re anything like me, you probably do most of your reading online these days. Of course, blogs, wikis, forums, e-newsletters and the like are great for staying on top of the news. Nevertheless, I’m still a great fan of the good old-fashioned printed word.

Below is a list of all the speakers at DIALOG 08 who have authored or co-authored a book related to the content of the conference - just in case you want to do a bit of background reading during your flight to Palm Springs:

If I missed anyone, please feel free to add a comment with a shameless plug here.

You might also want to check out the reading list that we’ve put together on the ILOG BRMS Resource Center website.

If you’ve got any other suggestions to share with other DIALOG attendees for must-read literary masterpieces that cover Business Rules, BPM, Optimization, Visualization, or Supply Chain Management topics, please add a comment here.

Green and lean

Monday, February 18th, 2008

Green logisticsThere is growing interest in understanding the impact of various supply chain decisions on a firm’s carbon emission footprint. This awareness is moving rapidly up the corporate, consumer and legislative agenda. I was pleased to see, therefore, that “green logistics” also features highly on the agenda for DIALOG 08.

On Monday February 25th (2:30 pm - 3:15 pm), Martin Brotschul from Accenture will explain the financial case for sustainability and green logistics and use case studies to assess best practices in green logistics and supply chain management.

Ahead of DIALOG 08, David Simchi-Levi, professor at MIT and co-founder of Logic Tools, the supply chain vendor that ILOG acquired in 2007, will present a webinar on Wednesday February 20th called Green & Lean: Reducing Carbon Emission in the Supply Chain in which he will review strategies that allow firms to stay “lean” while becoming more “green.”

David will also be at DIALOG 08 and with a bit of luck I’ll get him to spill the beans about some forthcoming additions to the Logic Tools network design and planning solution designed to help you make your own supply chain that much greener. Watch this space!
