This is the hardest thing that you can do in a business - change the way that you do business. Generally, methodologies to change are very resource intensive because they have to involve people actually changing their behaviour and activities - their actions. You don't do that by listening to lectures, you have to apply it in practice. Applying this in the real world is dangerous obviously. This is precisely why many change programs tend to fail.
People are worried to take action, to make the wrong decision.
What I think is so impressive with MTN is that they are soliciting advice from all their staff. They are asking their own staff those questions. They will do it themselves, I won't do it. What I help companies with is to ask the questions. Those that see this as a quick fix solved by applying a checklist, they fail - always.
