Cost of ChangeOne basic premise of agility is the value "Responding to change over following a plan". Basically, this value is made real by constantly reducing the cost of change, to the point where you'll never need to follow an invalid plan simply because it costs less to continue doing the wrong thing. A low CoC is a premise for "being agile".
|Correlation between agility and Cost of Change|
Let's look closer: Change does have a cost associated, and you can't simply declare that cost to be Zero, in disregard of every evidence to the contrary. You must understand what the cost of change for a given change at a given time actually is.
This is where the coach/consultant comes into play. Both have the responsibility of inducing change. The coach would work on getting the responsible people, for example the teams, to embark the change process by learning by themselves. They need to be cautious, as especially in the initial stages of agility, the cost of change may be extremely high.
Cost of Failure
There's a problem in the learning process: Learning, obviously, means that you haven't done it yet. And that can pose a problem: You might fail. Well, failure is not inherently bad. We might argue that failure is an essential part of the learning process. That may be true, but you need to be aware of the failure costs.
|Expected Cost of Failure|
It's a completely different thing to "learn" that it's a bad idea to first pull the pin from a hand grenade, then put the grenade into your pocket: There won't be a next time.
In both cases, we assume that failure may occur. In the first case, we will assume that we can safely let people find out what happens, because the cost of failure is low. In the second case, however, it would be highly immoral to know the cost of failure and still let people figure out what happens.
Impact on the approachWe should always consider the cost of failure for any potential course of action. Low-risk topics that pose little danger to organizational health are not typical scenarios for requiring external support. Hence you wouldn't hire a consultant for that. People are more likely to ask for help the closer they feel to being to the Point of No Return.
Self-learning is a better course of action only when two conditions are met: 1) We will not cross the point of No Return and 2) It's a positive long-term business case.
Even though, I do admit that 1) automatically invalidates 2), the latter might still be easier to figure.
If those conditions are not met, a prescriptive course of action is more appropriate.
