Planning Ace's guest host Brett Knowles suggests that GPT can be used as an extra member at the planning table, providing a catalyst for exploring ideas and expanding horizons. By generating scenarios and validating strategies against them, planners can identify environmental and situational factors that need to be true for a strategy to work.

But the true power of GPT lies in its ability to test a plan through the eyes of different stakeholders, such as investors, regulators, competitors, and employees, before presenting it to the executive committee. This allows planners to pretest their plan against a vast knowledge base, beyond the limited experience of the leadership team.
