Attrition

The rate at which employees leave your support team. This can be both external (leave the company) and internal (move to a different team). It can also be voluntary or involuntary.‍

• One important consideration in setting cost-saving goals is a potential increase in attrition, which could offset any operational gains made.
  
• "Annual Attrition Rate" is commonly used to measure attrition and is calculated by dividing the number of employees who've left the team by the average number of employees throughout the year. For example, if the team was 90 employees at the beginning of the year and 110 employees at the end of the year and 15 employees left the team during the year, the annual attrition rate would be: 15 / ((90+110)/2) or 15%.
