Which of the following is NOT one of the reasons that a
company's strategy evolves over time?
The need to respond to important technological breakthroughs
and/or the fresh moves of competitors
Ongoing management efforts to fine-tune this or that piece of
the strategy and to adjust certain strategy elements in response to
new learning and unfolding events
The need to keep strategy in step with changing market
conditions, advancing technology, and/or newly emerging market
opportunities
The deliberately planned efforts of company managers to make
frequent strategy adjustments that will surprise rivals and keep
them busily engaged in defending against its latest moves in the
marketplace.
When the present strategy is clearly failing, perhaps because
market conditions or buyer preferences suddenly change
dramatically
