“I use social media the entire time I'm at work - it's on constantly and I use it concurrently with other applications. If I was to pull out the time on
various forms of social media and put them into one block it'd be about 30 minutes a day on average, spread over an 8 or 9 hour day.”
How many hours per day do you use social media applications to communicate?

What can your team do now that they could not do before
social media?
“Communicate out of hours, conveniently and from any suitable device”
“Avoid having to turn to email as primary communication tool”
“Communicate rapidly”“Work from home to a greater
degree”“Ask questions without interrupting
each other‘s flow; clarify small questions quickly; chat informally while working”
“work from different locations”“access more expertise”“ensure transparency”“work with open source community
”
• Faster and easier problem solving
• More rapid and comprehensive testing
• Ongoing user feedback• Easier to share best
practice• More communication
between stakeholders• More information available
for decision making
Social media brings many benefits to the software development process
