A: Decision Critical uses constraints (bottlenecks) as the basis of its operations modeling. Each model assumes that sales are equal to the lesser of demand and availability. Availability is itself determined by referencing capacity and other items, such as willingness to build inventory. Capacity, in turn, is a function of access to resources, including labor, equipment, floor space, financing, etc.
Decision Critical reviews user-entered preferences on the above items, including available resource quantities and production prioritization, and subsequently models operational performance first and foremost, before then building a financial model on top of it.
