J. Paul Dittmann, Ph.D.

If you have read part one of this two-part white paper on cost reduction in the healthcare supply chain, you already know that this is a complex and challenging topic. You also know that you need to “change the game” as you squeeze out more cost from processes that are already virtually stripped bare of excess.

Part one provided guidelines for your journey to world-class cost management. This part is designed to help you take the next step and identify specific cost reduction projects in your firm. As in part one, I’ll focus on five areas of supply chain cost:

  1. Inventory and Order Management Cost
  2. Supply Chain Security and Regulatory Compliance Cost
  3. Procurement Cost
  4. Warehousing Cost
  5. Transportation Cost

As we proceed from inventory and order management cost through other areas of opportunity, I’ll provide a checklist of best practices to consider in optimizing each cost element.

You will find a target-rich environment as you work through this material—most likely so rich that you will need to prioritize your goals. In setting cost-reduction priorities, I recommend that you follow the three-step process outlined below.

1. First, use the checklists and recommendations in this white paper as thought starters to draw up a preliminary list of cost-reduction ideas. You may want to take a team of internal experts off-site and brainstorm the subject area. Expect the list that results from such an exercise to be very long.

Dittmann 12. Once you develop your list of cost-reduction options, it’s time to prioritize them. You simply can’t do everything. I recommend that you do an initial screen by plotting potential projects on a two-dimensional graph like the one below and then focus first on projects in the bottom right of the diagram.

3. Once you have used this technique to pare your list down to a manageable number of options, it’s time to do a detailed analysis of return on investment (ROI) for each opportunity on the list, identifying as precisely as possible the cost, other investment requirements, and benefits of each. When that’s complete, you’re ready to select a project manager, prepare a detailed project plan, and execute using a disciplined project management process.

4. You could then replot potential projects and prioritize your goals, developing a longer-term roadmap.

1. Inventory and Order Management Cost

Standardization

Although it may sound mundane, lack of data standardization is a huge obstacle for achieving healthcare supply chain excellence.

Lack of data standardization is an obstacle for achieving healthcare supply chain excellence.

Global GS1 standards (data standards used in bar codes and other product identifiers) can bring the whole healthcare supply chain industry together around uniform identifiers. That, in turn, could facilitate the automation of a whole host of supply chain operations, bringing major cost and inventory savings. If GS1 standards are used by the manufacturer, distributor, and customer, then:

  • Orders can be scanned at receipt and put away efficiently
  • Accuracy can be better verified
  • Inventory systems can be automatically updated upon scan
  • The replenishment process can be automated

Having accurate data visibility throughout the supply chain can go a long way toward addressing the inefficiencies in many healthcare order and inventory management processes. What’s more, GS1 standardization can also serve as a foundation for other supply chain technology.

According to the seventh annual UPS Pain in the Chain study,1 healthcare supply chain decision makers are becoming increasingly aware of the advantages. Nearly half of the respondents say they are undertaking an initiative like this.

Using technology

Modern inventory management and advance planning systems can help optimize the “safety stock” you carry for each SKU in each inventory location.

In the UPS Pain in the Chain study, 66 percent of respondents said they intended to invest in IT systems. Three-quarters of these said they would implement an order management system and 63 percent said they would create a web ordering system.

Let this principle be your guide: Technology should simply be an enabler for a new, carefully thought-out process that is consistent with your overall supply chain strategy. (The development of a supply chain strategy is dealt with in the first paper in this series.)

Choosing the right order and inventory system

Only you fully understand your business needs, so first develop a list of requirements. Then invite prominent software vendors to demonstrate how their software meets those requirements. “See it before you believe it” is a good philosophy; vendors have been known to exaggerate. A useful checklist of elements worth considering follows.

  • Vetted references
  • Ability to integrate easily with the existing enterprise resource planning or legacy systems
  • Licensing and ongoing support costs
  • Estimated ROI
  • Scalability and flexibility to accommodate future requirements
  • User-friendliness
  • Financial viability of the supplier
  • Quality of after-hours support
  • Cost-benefit analysis
  • System stability, unless there is tolerance in the firm to operate a beta version
  • Buy-in from the line organization
  • Implementation costs

A scoring system should be used for software selection. To maximize organizational buy-in, the scoring team should be large and cross-functional. Each element in the evaluation criteria should be listed and weighted for its relative importance. For each major capability required, the scoring could be something like this:

Capture

Once the weighted totals are tabulated and a good dose of judgment applied, a decision should be easy to reach.

Additional inventory reduction ideas

There are a number of additional things you can do to reduce inventory without negatively impacting service.

  • Use the latest technology
    Systems exist to optimally set safety stocks based on unique product characteristics, such as supply and demand variability. Evaluate new decision-support systems using the process outlined earlier in this white paper.
  • Improve forecasting
    You can’t improve forecast accuracy if you don’t measure it. Measure the accuracy of your demand forecast SKU by SKU and make it visible within the company. Then look at demandsensing forecasting approaches.
  • Measure and reduce lead time
    Longer cycle times in extended global healthcare supply chains can cause more inventory than necessary to be carried. You should measure lead time at each phase of the supply chain and look for ways to reduce it.dittmann 3
  • Embrace segmentation in your inventory policies
    Not all customers and all products were created equal. Each product/customer segment needs a unique inventory policy appropriate for its position in the marketplace. You should have a segmentation policy both for customers and products.
  • Develop a thorough new product introduction and sunsetting process
    New products come out constantly in the healthcare field. Your firm needs disciplined processes to manage new SKUs and forecasts, and to control SKU phase in/phase out.
  • Reduce unnecessary SKUs 
    You need all of the SKUs your customers require, but no more. Unnecessary SKUs consume and hold inventory, and hurt product availability. In most healthcare firms, 20-30 percent of the SKUs are dead and need to be eliminated.
  • Address obsolete and slow-moving inventory
    Product damage and spoilage were cited as major concerns by 62 percent of respondents in the UPS Pain in the Chain study. Obsolete inventory never gets more valuable, but instead continually generates cost to keep and store it. That’s why your company needs an aggressive plan to regularly dispose of aging and obsolete inventory, which becomes increasingly likely to spoil.
  • Set the right accountability
    It should not be the sole responsibility of the supply chain organization to reduce inventory. Your firm needs to recognize that sales and marketing have a major role to play in inventory management and they need to be incentivized to do so accordingly.

Technology should enable a carefully thought-out process that’s consistent with your supply chain strategy. 

2. Supply Chain Security and Regulatory Compliance Cost

Supply chain professionals face major costs due to regulation and security issues in the healthcare arena. Managing this reality calls for a strategy with a prioritized, multiyear action plan.

There’s a lot to do in response to these two challenges, and a significant cost associated with all of the actions. Again, you can’t do it all at once. So make sure you choose a plan that promises the largest possible return on your regulatory and security project investments.

Measure the cost, measure the benefit, and implement with a rigorous project management and change management process. It is worth returning to Part 1 of this paper for a refresher on a number of specific recommendations on controlling security and compliance cost. This includes a checklist of 8 ways to make distribution centers more secure.

3. Procurement Cost

The optimal procurement cost is not necessarily the lowest unit price. In order to achieve the optimal cost, there are a number of other considerations. In particular, the procurement team should follow the thirteen principles outlined below.

Collaborate with key suppliers
In the UPS Pain in the Chain survey, 61 percent of respondents cited collaboration as a successful strategy. While this applied to logistics partners in the study, it could be equally useful for any supplier from chemical suppliers for pharma firms to component suppliers for medical device companies.

There are well-known best practices regarding how to establish a win-win relationship with suppliers. In advanced relationships:

  • Each party measures performance using the same metrics
  • They agree to share savings 50:50
  • There are clear bottom-line improvements in cost, inventory levels, and customer service

Only a critical few suppliers should be identified for this type of partnership, given the time required to manage.

Support vendor innovation
It is important that firms support their suppliers and provide them with the information and commitment they need to innovate. Suppliers should be contractually incentivized to generate savings through innovation.

Selectively manage inbound transportation
Pricing should always be quoted two ways: prepaid and collect. Determine whether you want to control the inbound transportation, or leave it to the supplier. Alternatively, you could contract a third party to manage it on your behalf.

Reduce vendor lead time and measure total landed cost
Lead time is a critical variable in managing both inventory levels and out-of-stocks, especially in the global healthcare supply chain. And, it’s rare to see total landed cost quoted (that is, the total cost of a product arriving on the buyer’s dock including taxes, transportation, and so on). Shorter lead times allow vendors to be more flexible and responsive, which can help reduce cost, stock outs, and inventory levels.

Consider logistics when designing packaging
Suppliers should develop packaging that can help minimize logistics costs, especially supply chain transportation costs. Practices commonly associated with sustainability measures— including the use of appropriately engineered packaging that avoids wasted space and sustainably sourced materials designed to complete the shipping process so that resends are unnecessary—have environmental, cost, and even reputational benefits, especially for shipments delivered to end-consumers. Look particularly for expert methods for creating and testing packaging described in the UPS white paper Cold-chain packaging: A new approach to packaging optimization and small-package cost management.

Measure the cost and benefit, and implement with a rigorous project and change management process. 

Evaluate vendors using a scorecard
Vendor scorecards need to include key logistics measures, such as damage rates, on-time delivery, lead time, packaging evaluation, and transportation cost. When you aggressively manage these items, you will see a major positive impact on your firm’s cost structure.

Consider your vendors’ reputations, too. While it is a more indirect cost, the companies you align with may color your brand perception. A company that fosters ethical practices and aligns with your company’s reputational goals is more likely to support the perception you seek to build with customers and shareholders.

Run a comparative analysis
The procurement team, in preparation for supplier contract and price negotiations, should carry out an in-depth commodity or competitive analysis.

Train procurement personnel on best practices
There should be professional procurement training in place and a personal development plan for each procurement professional. Organizations such as the American Purchasing Society can provide assistance to companies and individuals.

Reduce and eliminate the impact of personal relationships
Personal relationships may play too large a role in negotiations. The impact of this phenomenon needs to be totally eliminated to capture maximum value. Some firms require that their procurement staff meet with suppliers only on-site, with no outside meals, gifts, or entertainment activities allowed.

Leverage the buy
There are huge benefits to increasing scale and leveraging the buy whenever possible. Leading firms centralize procurement globally and so should you on the largest appropriate scale.

4. Warehousing Cost

Distribution center management cost reduction ideas

Cost reduction best practices in distribution centers largely fall into six areas. I discussed each one of these in part one of this white paper. Below are additional cost reduction ideas to consider.

Receiving

  • Use automatic shipment notifications (ASNs). These have been shown to reduce receiving costs by 40-50 percent.
  • Improve overall distribution center efficiency by using only qualified suppliers who ship on time, with quality and reliability.
  • Put away product quickly to alleviate congestion and its associated waste.
  • Manage returns efficiently.

The optimal procurement cost is not necessarily the lowest unit price. 

Picking and order fulfillment

  • Use a profiling process to locate the highest volume SKUs in the easiest-to-pick locations.
  • Use an appropriate level of automation, such as radio frequency picking, pick-to-light, etc.
  • Consider whether you have the right level of focus on the omnichannel, and develop an efficient process to fulfill Web orders.
  • Look to opportunistically coordinate inbound and outbound loads in order to eliminate put-away and picking operations that represent the lion’s share of the labor in a distribution center.

Lean warehouse management

  • Keep it simple and focus first on total employee involvement, management walkabouts, and visual management.
  • Keep things in order with a methodology such as 5S (a quick Internet search will be helpful).
  • Then, later, take out 20-50 percent of the operation’s waste with value-stream mapping.
  • Use Six Sigma techniques to reduce process variation and improve efficiency.

Warehouse management systems (WMS)

  • Implement a modern WMS.
  • Using the WMS, efficiently organize put-away, picking, shipping, labor management, yard and dock management, and other key distribution center activities.

Warehouse space optimization

  • Optimize warehouse space by managing all stacking heights, appropriately using racks and mezzanines, managing docks and aisle size, and so on.
  • Avoid exponential productivity declines by making sure the distribution center does not become too crowded.

Warehouse network optimization

  • Use modern software or a partner resource to evaluate how many distribution centers you should have, where they should be located, and which customers they should serve.

5. Transportation Cost 

In order to meet the challenge of increasing transportation costs, leading companies pursue a combination of the thirteen initiatives listed below.

Find a good partner
More than half (56 percent) of healthcare firms distribute to wholesalers or distributors, and 46 percent ship directly to customers. About one-third of overall transportation and warehousing spend is outsourced. Selecting and contracting with a good third-party provider that will flex with your needs is critical to controlling cost in the healthcare supply chain.

Develop an efficient cold-chain process
This is especially important in the pharmaceutical industry. The UPS Pain in the Chain study found that product damage and spoilage is the fourth-highest concern among supply chain professionals. And 69 percent of healthcare supply chain decision makers cited adverse weather and temperature environments as a top challenge to product integrity.dittmann 4

Focus on cube utilization
In other words, consolidate orders. If you can increase the average cube (or weight) per load, the additional product rides for free. One retailer who rigorously manages cube utilization gets about 3,000 cubic feet of product in the average fifty-three-foot trailer (a very high volume indeed; a standard trailer holds 3,800 cubic feet).

Use more rail, intermodal, and ocean
Using more rail and intermodal clearly reduces cost. However, it often means adding time to the supply chain, which translates into additional inventory in the system and may be inappropriate for many healthcare products. This is also one of many areas where there is a classical tradeoff between transportation cost and inventory cost. Each operation is unique. Also, switching from air to ocean transport can save 70-80 percent of cost in the healthcare supply chain.

Optimize the network
This is a strategic approach to reducing transportation cost. One healthcare retailer serves about 200 of its stores from each distribution center. Every year, it saves $1-5 million in transportation cost by using a network optimization system to revise which stores should be served by which distribution center. Manufacturers can do much the same thing by reevaluating which customer locations should be served by each distribution center.

Implement a transportation management system (TMS)
A modern TMS can improve fleet routing, load tendering, and delivery scheduling, saving a significant amount of transportation cost.

Reduce empty backhauls/revenue generation
Many companies actively look for backhauls to avoid empty miles and generate revenue to offset cost. One healthcare retailer delivers to stores all over the U.S. and also has vendors spread across the country. This company constantly looks for ways to unload at their retail stores and use the same vehicle to pick up vendor product for an almost-free return trip to one of its distribution centers. Another manufacturer company actively sells empty capacity on its backhauls and generates millions in revenue each year that flows as a credit into its freight account.

Manage inbound freight
Inbound freight often finds its way into vendor product purchase price rather than to the transportation budget. But, it is a transportation cost nonetheless. Leading firms request freight collect and freight prepaid bids from all of their vendors and then take over the control of the inbound shipments that make economic sense. One small grocery retailer ($7 billion in sales) saved over $10 million in a small pilot by controlling certain inbound loads and is looking to expand this and realize a $40 million savings.

Your supply chain is potentially a huge competitive advantage and a major contributor to shareholder value in your firm.

Focus on driver retention
The great driver shortage is upon us and it will not abate for the foreseeable future due in large part to demographic and social trends. The no-brainer solution is to simply pay more and no doubt that will be required. But companies can do a lot of other things to retain drivers from flexible work arrangements to creative bonus plans.

Manage the flow and peaks
The HOS (hours of service) regulations penalize companies greatly when drivers have to wait. And drivers have to wait when there are workload peaks. One company told me that they ship 40 percent of their loads on a Monday. They are now looking at moving to a 7-day operation to smooth shipments throughout the week. Using industrial engineers or Six Sigma techniques to optimize the loading and unloading process can also help greatly in this area.

[Also on Longitudes: Hidden Risks in Your Supply Chain]

Minimize express/air shipments
Often, inadequate planning systems or a fundamental lack of flexibility and responsiveness in the supply chain lead to a need for emergency shipments. Firms need to track these shipments, identify root causes, and develop an action plan to tackle them.

Manage global import/export cost-efficiently
Global transportation represents a major source of transportation cost in international corporations. Special expertise is required to efficiently manage freight in the global environment. This implies world-class, third-party relationships, along with advanced in-house expertise.

Manage product security efficiently
Product security was the second-top supply chain concern in the UPS Pain in the Chain study. Serialization is now a focus for pharma products, and requires a comprehensive system to track and trace the movement of prescription drugs through the entire supply chain. Every product should be identified by a unique serial number in addition to the origin, shelf life, and batch number. Counterfeiting by organized crime can be reduced significantly by implementing product serialization and e-pedigree documents (electronic documents that provide data on the history of a particular batch of a drug).

Conclusion

This paper provides some ideas to manage cost in the extremely challenging healthcare supply chain. I recommend that you use this as input to develop a multi-year plan. Set some stretch objectives. Remember, your best today may not be good enough in the competitive world of tomorrow. So, keep raising the bar for your business processes. Your supply chain is potentially a huge competitive advantage and a major contributor to shareholder value in your firm. goldbrown2
