But if planning and agility are both necessary, organizations have to make them work. They have to create a Venn diagram with planning on one side, agility on the other, and a practical and workable sweet-spot in the middle. This is why the quest to rethink strategic planning has never been more urgent and critical. Planning twenty-first century style should be reconceived as agile planning.

Agile planning has a number of characteristics:

• frameworks and tools able to deal with a future that will be different;
• the ability to cope with more frequent and dynamic changes;
• the need for quality time to be invested for a true strategic conversation rather than simply being a numbers game;
• resources and funds are available in a flexible way for emerging opportunities.
