Nice to always have another perspective when brainstorming ideas and even a pattern to follow, the article "How to Host Successful Inter-Agency Brainstorms" mentions 3 areas of focus when setting up your next meeting that you can adapt to any session for any client....
"1) Identify exactly what you are looking to achieve from an ideas perspective.
As we've all witnessed, the term BIG IDEA means something different to everyone. Identify the phase you are in along the communications development continuum and give precise direction as to what you are seeking from agencies:
- Phase 1- Creative Platform. The overarching campaign theme, e.g., the Ford Fiesta Movement
- Phase 2 - Mega-Tactics. Big tactics that can be channeled across multiple platforms, e.g., Ford selected 100 "agents" to test drive Fiestas for six months, take on "missions" and lifestream their experience via social media
- Phase 3 - Mini-Tactics. E.g., Tweetups, Flickr pages
2) Don't host a traditional brainstorm, but rather an "idea share & build"
Inter-agency brainstorms are not necessarily effective for developing creative platforms or mega-tactics. These require careful deliberation from agency Creatives, who often come up with their best thinking outside of the brainstorming environment. It is best to instruct each agency to come prepared to present one to two creative platforms and associated mega-tactics. After all agencies have presented, host an "idea build" session in which all participants can build on the ideas and provide tactical suggestions. If you have a great moderator, he or she will be able to establish linkages between ideas and potentially merge some.
Same applies if you are in a more tactical stage of creative development. Agencies should come prepared with "mini-tactics," and then host an "idea build" to generate additional tactics and establish linkages between tactics.
3) Identify a core decision making team to finalize plans
After the inter-agency brainstorm, a core team will need to determine how to proceed, which may involve researching ideas or simply moving forward with favored ideas. While each agency can be offered the opportunity to cast a vote in favor of an idea, ultimately a small team needs to make the final decision.
On a final note, if you truly want Big Ideas, lose the catch-all phrase BIG IDEA. It's time to get specific."
These are truly some great guidelines for your next brainstorming session, try them the next time you need a BIG IDEA.
