In a study I completed in the summer of 2006, 187 business executives provided insights into the role of mobile phones in their jobs.

In a 5-point scale, the top box are the top 2 boxes - Useful and Very Useful (for example). In this study, we described four enterprise mobility features:

• Call Screening is the notification of incoming calls with the option to determine call disposition such as send to voicemail, or forward to a coworker
• Instant Messaging is the ability to determine the availability of a coworker (presence) and to use text messaging instead of actually calling that person
• Directory Search is the ability to perform corporate directory lookups from a mobile phone
• Group Call is the establishment of an instant conference call for a pre-determined group who are invited to participate in a call immediately
