This event tests new technologies as part of a global coalition response to fictional terrorist incidents in North America and war scenarios between four imaginary countries. It brings together homeland security departments, military forces and intelligence agencies to assess how well they can use and exchange information ("interoperability"). Microsoft(R) SharePoint(R) Portal Server is using OSI's Common Operational Picture product line (COP PL) as a key part of the information technology for the exercise.

The new offering from OSI acts as a powerful networked collaboration tool that provides battle commanders, civilian security and counter-terror agencies with a "virtual command room" for regular situation briefings and decision support. For the duration of the CWID exercise, the map and target display capability is provided by OSI's COP product line.

The purpose of CWID is to identify technology that can solve interoperability challenges and be fielded in 12 to 18 months. According to independent consultants Frost and Sullivan, interoperability and situational awareness are two of the top three most critical issues facing the defense and security market today. OSI's COP PL, which is designed to enable situational awareness and interoperability, will be formally assessed for its effectiveness by 14 evaluators, representing the navy, air forces, land forces, marines, special forces and intelligence analysts, at over 12 locations in Canada, the U.S., Europe, Australia and New Zealand. Based on independent research, OSI estimates US$400 million is currently spent each year on map display technology for command and control.

As part of the SharePoint portal solution, COP PL is available as a window for every participant on the CWID network. "It's like having a mini-TV screen on your computer providing a constant picture of the battle in real-time," said John Jacobson, OSI's President and CEO. "During a briefing, commanders, warfighters and intelligence analysts, regardless of location, can open COP PL and see the exact same image of what is happening in the field: where the enemy is, where the coalition forces are, what the terrain is like, battle commands - essentially multiple streams of information all on one screen. Being able to connect everyone to the entire battle picture, from anywhere, at once, supports situational awareness and the interoperability of all forces. To our knowledge, this is a unique capability for the defense and intelligence community."
