Did you hear about the infamous Army briefing during the Vietnam War? "We had to destroy Ben Tre in order to save it." The briefing referred to a terrible act, the annihilation of a Vietnamese village by overwhelming American firepower, carried out during a terrible war that was lost in any case. So it goes when tactics, rather than strategies dominate a conflict. Less gruesome, but relevant is the bungled tactical war between advertisers and agencies. Well-meaning tactical "best practices," used extensively and nearly universally by marketing procurement departments, are worst practices that destroy agency capabilities and annihilate partnerships. Unfortunately, agencies are equally complicit in their destruction.
