Why rollouts fail
In almost every case we have seen, the software was not the problem. The rollout failed because the old route stayed open. As long as customers keep writing to personal addresses and colleagues keep asking in the doorway, the ticketing system is additional work – not a replacement for existing work. The second common mistake is over-structuring: defining fifteen categories, four priorities and three escalation levels before the first ticket produces a model that has nothing to do with reality and that nobody maintains.
