Collaboration is one of the key success factor for any business. Collaboration tools are broadly segmented into two categories.
  • On line meeting
  • Social Networks.
Online meeting tools are particularly important as no one   wants  to waste time , money and energy in travel whereas  Social Networks are the key ingredients for:
  • Contacts Management
  • Sales/ Leads generation
  • Recruiting / Referral
  • Product Announcements
  • Marketing and Brand Building
