The Happy Accident, which is often cited as a principal ROI of enterprise social networks, refers to the chance discovery of the right person or the right piece of enterprise knowledge to solve a business or process challenge. For instance,  Bruce in Melbourne, dealing with a corporate crisis,  fires off an anxious  Yammer/Jive/Tibbr post at 6.00pm in the evening Sydney time, before heading off to a nervous sleep. Meanwhile, as Bruce slumbers fitfully, at 3.00am the following morning Colleen logs in from Dublin and comes across the post and immediately fires back with the critical data. Bruce did not know Colleen was the one to turn to, nor even how to find here, it was all a Happy Accident. Enterprise Social wins again!
