  5. 5. Define the Application  What business process can benefit from video conferencing?  What are the characteristics of this application?  Conversations within the enterprise or outside the enterprise?  Are meeting members meeting for the first time or do they already know each other?  Executive meetings? Team collaboration?  Will there be shared materials? Is this material on computers or is it physical in nature?  Short meetings or long meetings?  Is the meeting space environment conducive to video conferencing?

  6. 6. Different Requirements, Different Solutions  Simple data  Ease of use sharing  Room system compatibility  Low BW demand  Low meeting fatigue  Perfect eye contact  Immersive experience ©2009, NetForecast, all rights reserved. 6
  7. 7. Return on Investment  Video conferencing is usually justified based on travel reduction  Travel reduction savings occur best with a top-down mandate  These savings can be real and can generate a 12-month ROI  The real value comes from improving business processes:  Allow more team members to ‘meet’ and establish relationships across distance without travel  Connect more in-house ‘experts’ to in-house problems or to partners / customers / vendors  Speed up development or marketing processes, get to market faster  Improve the quality and speed of cross-company programs through more frequent and higher quality interactions ©2009, NetForecast, all rights reserved. 7
