This set of indicators might stay static, but after some work (iterations), it is also common that some that are deemed not to be as fruitful as expected are simply removed. Similarly, some new ones might be added over time, both to follow the evolution of the system as well as to widen or deepen our understanding of it. All this is done to improve its efficiency.
