Expert SIOP Consulting for Balanced Supply and Demand

The sales, inventory, and operations planning (SIOP) process is the closest to a crystal ball that companies can use to balance supply and demand, control cash flow, make informed decisions, and move with confidence into the future.

SIOP is a formalized, collaborative, and cross-functional process that allows you to meet customer demands while building flexibility and responsiveness into your plan-make-buy-move supply chain.

As the #1 supply chain and operations firm in North America, we understand that planning, procurement, operations, and logistics interact constantly. We help you create data-based, company-wide strategies for optimizing supply, demand, and production despite the vagaries of the market and economy.

What is the goal of SIOP? 

The SIOP process links people, processes, and information to set the course of action across finance, budgeting, sales, marketing, sourcing, labor, production planning, inventory control, plant operations, and distribution center logistics. It is a monthly, data-driven, fact-based planning process that adjusts to meet current market conditions and expectations.

The SIOP process synchronizes accountability, timelines, and decisions to:

  • Balance supply and demand
  • Optimize materials and working capital across the supply chain
  • Meet customer requirements at the lowest possible cost.

Where we add value 

Collaboration across the end-to-end supply chain is only one step in creating a resilient SIOP process. We deploy advanced analytics, simulation models, and leadership and organizational improvement (LOI) to bring supply and demand into alignment. Our playbooks enable your team to consolidate its progress in SIOP and embark on continuous improvement.
