Vigilant Information Systems is a knowledge discovery technique used to dynamically alert the user of internal and external changes in an organization so as to sense and respond to these changing dynamics faster and better. This system was successfully implemented by Western Digital to manage its Supply Chain, production and corporate affairs. Here, the Dashboard called “Real Time” provides interface to end users (Management and executive staff), using which they could monitor the changes and act accordingly. Though the conventional Information system has been quite helpful in making decisions, accessing database repeatedly, analyzing this huge data and presenting it to the staff is a tedious task taking both Management and Executive staffs’ time and resources. Alternatively, in VIS, the process is initiated by the database signaling an alert to the end-user as and when change occurs. As data is fed in dynamically, Dashboards provide easy user interface to review and act upon it immediately. The process is divided into four phases:

Observe – See change signals

Orient – Interpret the signals

Decide – Formulate an appropriate response

Act – Execute the selected response.
