Although I'm no longer completely Call Convinced That the "core competencies" approach is always the right approach to stategic planning, Hamel and Prahalad's work is important reading. Every Organization Should understand its core competencies and take them into account in Their Strategic Planning Process. Having said that, HOWEVER, I personally prefer the "Key Strategic Driver" concept laid out by Mike Robert in his book "Strategy Pure and Simple". When working with my clients on strategic planning activities, we discuss core competencies Often as a prelude to exploring the company's "Driving Force" or "strategic heartbeat". Adam Lefton
