Serviceability is the ease or difficulty with which an equipment can be repaired
Intuitively, it would seem that some term should be used to represent the degree of ease or difficulty with which an equipment can be repaired. The term “serviceability” has been selected for this concept. Serviceability has a strong influence on repairability, but the two are essentially different concepts. Serviceability is an equipment design characteristic,
while repairability is a probability involving certain categories of time.
