3 Data to Decisions

4 Levels of Management Decision Making Strategic – group of executives develop overall organizational goals, strategies, policies, and objectives as part of a strategic planning process Tactical – managers and business professionals in self- directed teams develop short- and medium-range plans, schedules and budgets and specify the policies, procedures and business objectives for their subunits Operational – managers or members of self-directed teams develop short-range plans such as weekly production schedules

5 Decision Structure Structured – situations where the procedures to follow when a decision is needed can be specified in advance Unstructured – decision situations where it is not possible to specify in advance most of the decision procedures to follow Semi structured - decision procedures that can be prespecified, but not enough to lead to a definite recommended decision
