What type of error is defined as a failure to carry out a planned action?

A failure to carry out a planned action falls under the category of an error of execution. This type of error occurs when there is a discrepancy between what was intended or planned and what was actually performed. It reflects a breakdown in executing tasks as originally intended, which can stem from various factors such as oversight, lack of skill, or an unforeseen obstacle.

In the context of this question, understanding that an error of execution specifically refers to the failure to implement a predetermined course of action helps clarify its nature. It is distinct from other errors, such as programming errors, which relate to coding or software issues, communication errors, which involve misunderstandings or failures in conveying information, and process deviations, which deal with diverging from established protocols or procedures. These distinctions highlight why an error of execution is particularly focused on the component of action not taken rather than issues arising from planning or interaction.
