A KPI, short for Key Performance Indicator, is a term widely used in business, corporate, and industrial nomenclature. KPIs are designed to measure the effectiveness of strategic business goals. Owing to their focus on the purposefulness of actions, various types of KPIs can be distinguished. Consequently, key categories include financial KPIs, such as net profit; quality KPIs, such as the number of defective units produced; and operational KPIs, such as work efficiency.
