There is, of course, only one real hazard - to fix a bug or make an enhancement and, in so doing, to introduce a new problem. The problem usually manifests itself in an area far away from where the changes have been made and so are easily overlooked. A disaster that will damage reputations!

Companies, like people, have their comfort zone. For people the comfort zone is defined by environment, activities, companions etc. For companies it really revolves around projects; the type of work, the size of contract, the relationship with the customer.
