Everybody wants to better their businesses and make serious efforts to do so, but maybe we could be more effective is the efforts were less serious and more fun. Business communication is always challenging within the organization, with customers, providers, contractors, etc.. This is in part because they are not face-to-face and because most times one or more people who could add significant value take a passive role, in part because most times there is someone who enjoys dominating the meeting. End result is incomplete and biased information and decisions.
One main reason why games work is because (a) they are fun, and (b) they make everybody to actively participate. Hohmann's book is a great starting point. The games cover diverse needs and conducted properly add significant value (and save costs) to teams, projects, and entire enterprises.
Don't get serious... instead, start using this book!
