Why team collaboration and communication is so painful?

A recent twit from Gerry Kirk that I follow on Twitter, is providing me with an answer to this question.

His recent link to Working Agreements is putting emphasis on it, not directly but indirectly.

When I read this, one thing struck me: there is a lot expected from everyone - not too much - but a lot. Failures at communicating these expectations will undermine your team. Not only at the Agile/Scrum level as explained by Nicolas but at all levels of your organisation.

People have to understand the purpose of the expected communication and collaboration activities. They have to value them as a practice and they have to buy into the technology that enables these activities to happen.

Again, the people, process and tool triangle...
