Margin erosion is considered the most costly outcome of supply chain disruptions, with 53 percent citing it as one of their top two issues. Consumer products, diversified manufacturing and energy companies were especially likely to report margin erosion as one of their most costly issues.

Forty percent of respondents cited "sudden demand change" as one of their two most costly problems--a reflection of ongoing challenges involved with growing customer expectations, short product cycles and emerging competitive challenges. Executives at retail and technology companies, which operate in a world where markets change rapidly, were most likely to identify demand change as being costly.

Executives surveyed recognize the strategic importance of supply chain risk, with 71 percent responding that supply chain risk is an important factor in their strategic decision-making. Nearly two-thirds (64 percent) claim to have in place a risk management program specific to the supply chain.

However, only 55 percent of surveyed executives think their risk management programs are extremely or very effective. The top two challenges according to executives surveyed were "lack of acceptable cross-functional collaboration" (32 percent), followed by "cost of implementing risk management strategies" (26 percent). There are also organizational factors making effective supply chain risk more difficult: Three-quarters (75 percent) of executives said their supply chain risk management model is organized around silos, which can lead to a lack of supply chain visibility and collaboration, and make it difficult to assess and manage risk on a holistic basis.

Although surveyed executives report using a wide range of tools to manage risk, only 36 percent use predictive modeling and less than one-third (29 percent) use risk sensing data, worst case scenario modeling, or business simulation--all tools that help drive more proactive management of supply chain risk.

"Many companies have some form of a supply chain risk management program, but unfortunately they do not always get the results they need from these programs," said Marchese. "To be effective, companies should take a holistic and integrated approach to managing supply chain risk and go beyond traditional approaches. Because of the complex nature of today's supply chains, disruptions will inevitably occur. True resilience means building in the ability to recover efficiently and decrease the impact of those events."

According to Deloitte--which was recently named a Vanguard Leader, based on capabilities, by Kennedy in Supply Chain Risk Management Consulting--the four important attributes that are critical to supply chain resilience are:

• Visibility: The ability to monitor supply chain events and patterns as they happen, which enables companies to proactively-and even preemptively-address problems.
• Flexibility: Being able to adapt to problems efficiently, without significantly increasing operational costs, and make timely adjustments that limit the impact of disruptions.
• Collaboration: Having trust-based relationships that allow companies to work closely with supply chain partners to identify risk and avoid disruptions.
• Control: Having policies, monitoring capabilities and control mechanisms that help confirm that procedures and processes are actually followed.

About the survey
Deloitte conducted a survey of 600 executives from manufacturing and retail companies with a minimum of $100 million in annual revenues to assess their attitudes and challenges in managing supply chain risk. The survey was conducted via both telephone and online interviews from July to October 2012. Thirty-six percent of the companies are headquartered in North America, 28 percent in Europe, 11 percent in China, 11 percent in Japan, and 7 percent in Brazil.
