I read a great comment on Silicon.com:

“There are two ways of injecting greater creativity into a strategic plan. The first is to avoid biases. When we asked 50 strategic planners what stood out about strategic decisions they did not regret taking, the most common answer was decisions where they understood all the decision makers’ biases. For example, risk aversion, overvaluing consensus and deference to seniority.

The second approach is to diversify perspectives. This approach can be accomplished by developing the strategic thinking skills of high-potential staff and middle managers.

For example, by asking them to shadow the senior executive team during strategy-setting. Another tactic is to debate deliberately extreme or unlikely views of the future to make those involved with strategic planning think more broadly.”
