Unified communications is many things to many organizations. There is no set collection of elements or functions required in order to call it “unified communications”, and the fluid and varying nature make it virtually impossible to define the unified communications market.
As this blog post explores, what should you include in the market projections for unified communications? Voice? Instant messaging? Email? Mobile / wireless communications? Audio / video conferencing? Leaving one or more of those elements out of the equation could grossly shrink the potential market and revenue projections, but including them all may give a false sense of grandeur to the UC market.
How would you predict the size and revenue potential of a market made up of varying components with no set elements?
