Change is constant…embrace it
Interesting article from Agile Advice.
A team can work with a “horizon of predictability”. This is the distance into the future which a team can be reasonably certain that plans will be stable. Depending on the environment, this may be as little as a few minutes, or as long as a month. It is rarely longer.
Failing to recognize this is what makes us say things like “I’m going to have X done in 3 weeks” only to see that prediction fail. Unfortunately we still spend too much time predicting the future and hoping that *this time* things will be just fine, because this time nothing weird can happen. Teams make this mistake way too often.
