Costs
In almost everything, there is a cost of doing something that must be balanced against the cost of doing nothing.
Everything we do in Service Management and Asset Management must be weighed on this scale.
The scale helps determine the “why” we are doing it.
For example, we do Change because the cost of outages and risk of disruption is greater than the cost. The same goes for Incident, etc.
So, since you are doing something (like Change) because it’s a worthwhile endeavor, we need to do it well. Very well.
The scales get messed up when we don’t do things well. The reason for doing it becomes less obvious.
