Wasting Resources – generic advertising rather than focusing on specific

market segments Precipitating Unwanted Warfare

– Causing a full-scale price war when only brand repositioning was necessary

Failing to Anticipate and Adapt to Changes– Following historical patterns– Underspending on Advertising
