In this question, it was necessary to specify what cycle you are talking about (product, food, life cycle). I will answer generally.
There are three main stages in The life cycle:
Growth Stage
Maturity Stage
Decline Stage
There are two situations in which the acceleration of the cycle phases is harmful
if the stage of growth is accelerated, maturity would not have time to reach its optimum.
If the stage of maturity is accelerated, then the decline phase will occur too quickly.
