Presence Information: Knowing The Availability Of ColleaguesPresence information lets people know whether others are available (e.g., online, away, busy, in a meeting, out to lunch). People can publish their availability so others know how best to reach them.user’s presence information turns to “away.” Using Office Communications Server’s integration with Microsoft Exchange calendaring and the PBX or IPtelephone system, additional state information is also automatically published — for example “in a meeting,” “on the phone,” “out of the office,” “free in x hours.”The receiver does not have to sift through repeated communication in email, IM, and voice messages. In a Forrester survey, 59% of workers stated they would save more than 15 minutes per day with this feature.Instant Messaging: More Immediate CommunicationInstant messaging (IM) is the capability to send and receive text messages in real time over the Internet or a corporate network. corporate network, adding security that does not exist with public IM systems like AOL, Yahoo!, MSN, and Google Talk.Web And Videoconferencing: Cost And Time SavingsAd hoc Web and videoconferencing improves efficiency in real-time decision-making by providing easy setup, links to presence management, and point-and-click conference launches. Value increases when the time to set up a videoconference drops to near zero. 60% of workers surveyed for a Forrester report indicated that they could save from 1 to 5 hours per week using real-time conferencing.2 Videoconferencing also reduces travel costs. Videoconferences are increasinglyreplacing business travel for internal meetings and client or supplier/partner meetings.Further, the cost of video hardware has dropped to a point where PC-to-PCvideo is being increasingly deployed for valuable, albeit seldom, mission-critical situations. Voice Over Internet Protocol (VoIP)Voice communications can be integrated with email, calendaring, voicemail/unified messaging, IM, and conferencing to provide a streamlined experience rather than the disconnected experience provided by legacy systems today. Further,VoIP can significantly reduce the cost of telephone communications. One-Click CommunicationWe are approaching a time where all you need to find someone is his name, and all the means of contact are available immediately. Several of the organizations interviewed are looking toward a single identity for each employee that aggregates all the contact information (even individual’s areas of expertise) stored in Active Directory with some of the ways staff in the organization communicate (phone, mobile device, conferencing, IM, email, calendaring). Finding the right person becomesfaster, and determining his availability and communicating via his preferred, context-dependent medium is smoothed because presence is integrated into Microsoft Office applications. Also, organizations are integrating presence into their own line of business applications more frequently; users can “click to communicate” from within the applications.MobilityA minority of users in the interviewed companies carry mobile devices that have been integrated into the UC platform. For some organizations, mobility is an important part of their UC solutions, while for others it is an adjunct set of capabilities for select users. Certain mobile devices can run the OCS client, thus integrating the mobile phone with the individual’s presence, IM, and email.Further, with a Windows mobile device, users can open and modify email attachments, attachments within IM and other Word, Excel, or PowerPoint documents.
Today much more cheaper, based on Virtualization and cheaper Phones!
The flexibility component of TEI captures that value using either the financial industry standardBlack-Scholes or the binomial option pricing models. Forrester values the above flexibility option atmore than $1.25 million.
Present value (PV): The present or current value of (discounted) cost and benefit estimates givenat an interest rate (the discount rate). The PV of costs and benefits feed into the total net present value of cash flows.
