@BGL,
Your point well taken. Multinational companies will have no problems in getting good CEOs. Look at EABL, Bamburi, NMG, GSK. Effective structures lack in most of local organisations such that often only one individual is identified with an organisation. Having said that, a huge organisation like Coca Cola suffered when its long serving CEO Robert Goizueta died. His replacement did not impress the major shareholders like Warren Buffet and they had to show him the door
