Definition

A family of systems is a series of systems that share the same basic core system characteristics, e.g., a main battle tank (MBT). If the family is developed nearly simultaneously, then two or more variants are developed which share the characteristics of the core system and additionally have unique characteristics based on its specific mission, e.g., Army MBT, USMC MBT. If the family is improved upon over time, as in a series of upgrades, blocks, or increments, then the family consists of a first increment system and then additional increments that are similar but improved upon from the first increment system, e.g., MBT Inc1, MBT Inc2 etc.
