This paper presents some of the heuristics that a system architect could use to preserve the full operational potential during the system's intended life span, and beyond. The proposed heuristics prevent a single subsystem from severely limiting the evolution and maintenance potential of the whole system. The durability of the system's function ought to have precedence on the subsystems' own evolution, resulting in improved system robustness. The scope of function durability is first exposed. Side topics are then examined and the way they relate to the system viability is discussed. The second part introduces the proposed heuristics. Rationale and illustrations are given for each of them.
