One of the most overlooked concepts in management decision making is ________.

A) symmetry in data
B) uncontrollable variation
C) technological improvements
D) theoretical reasoning

Uncontrollable variation is often ignored or overlooked in management decision making. This refers to natural or random variation that is present in any given process or system and cannot be controlled through managerial actions. Ignoring this variation can lead to incorrect decisions and suboptimal outcomes. Therefore, it is important for managers to understand and account for uncontrollable variation in their decision making.
