Question 1a.

1a What is it that appears to make implementation of a renewal strategy so difficult?

I think the single most difficult part of implementing a renewal strategy is overcoming prior habits and patterns. This may not always be the case because if the right people are in the right positions of the business, then the need for change or renewal is most likely understood and supported. If not fully supported by all functional areas or personnel then the needed changes will be harder to implement.
