This document discusses different models for business presentations: SPADER, SOSTAC, and Get-To-By. SPADER is a 6-step process for communicating that includes situation analysis, problem definition, alternative solutions, decision, execution, and review. SOSTAC follows a similar 6 steps of situation analysis, objective, strategy, tactics, action, and control. Get-To-By focuses on defining the target audience, desired action, and strategy to achieve it. The models provide frameworks to structure presentations to achieve desired outcomes and actions.
