Monitoring key Performance Indicators

Key Performance Indicators are quantifiable measurements that reflect the critical success factors of an organization. They will differ depending on the organization. 

• A school may focus its Key Performance Indicators on graduation rates of its students.
• A Customer Service Department may have as one of its Key Performance Indicators, percentage of customer calls answered in the first minute.
• A Key Performance Indicator for a social service organization might be number of clients assisted during the year.

This sample develops and visualizes couple of KPIs (Key Performance Indicator) for a phone retail store. The developed KPIs are 
 

1. Quantity sold from each phone model -  The owner wants to know the performance of his product line. Total sales for each of the phone model is required.
2. Number of orders received by each customer - The owner wants to know the no of orders received by each customer.
