Using Probabilistic Models to Understand Risk • 201
ensure that model outcomes are statistically signicant and provide
sensitivity curves that explain the cause- and- eect relationships
within model scenarios.
• To manage risks in complex supply chains, leading companies will
combine risk response plans with digital modeling to provide pow-
erful risk management frameworks.
• Many best- in- class companies that practice elements of SCRM are
also leveraging additional lean/ Six Sigma methods such as FMEA to
identify, codify, classify, and force- rank risks throughout their sup-
ply chains and processes.
• Several leading companies in SCRM are also injecting stochastic/
probabilistic tools and techniques along with lean/ Six Sigma methods
into their normal S&OP processes to not only assist in supply/ demand
balancing, but also to develop a risk assessment process to make
informed decisions about their supply chains that take into account
uncertainty, complexity, and risk.
• e methodology of leveraging digital modeling, probabilistic tools,
discrete- event simulation, and risk assessment is a powerful envi-
ronment to evaluate operational alternatives without experimenting
on customers.
