SOSTAC® is a planning model, originally developed in the 1990s to help with marketing planning by PR Smith, who is my co-author on Emarketing Excellence.

SOSTAC® stands for:

• Situation – where are we now?
• Objectives – where do we want to be?
• Strategy – how do we get there?
• Tactics – how exactly do we get there?
• Action – what is our plan?
• Control – did we get there?
