Key Performance Indicator (KPI) is a measure of performance which are commonly used to help an organization define and evaluate how successful it is, typically in terms of making progress towards its long-term organizational goals. KPIs can be specified by answering the question, "What is really important to different stakeholders?". KPIs are monitored using BI to assess the present state of the business and to assist in prescribing a course of action. KPIs are frequently used to "value" difficult to measure activities such as the benefits of leadership development, engagement, service, and satisfaction. KPIs differ depending on the nature of the organization and the organization's strategy. They help to evaluate the progress of an organization towards its vision and long-term goals, especially toward difficult to quantify knowledge-based goals. A KPI is a key part of a measurable objective, which is made up of a direction, KPI, benchmark, target, and time frame. For example: "Increase Average Revenue per Customer from $100 to $150 by year end 2010". In this case, 'Average Revenue Per Customer' is the KPI.
