Gareth Rushgrove, a senior software developer at Puppet, describes how certain agile practices can help you, the IT manager, align your team with DevOps concepts and practices. Gareth encourages pair programming both for getting to better code more efficiently, and for sharing knowledge within your team. He also recommends co-locating people so they can get to know each other better. Inviting members of the other team to meetings is helpful, too. Gareth recommends that developers invite IT operations team members to their weekly gatherings, and that operators should invite developers to postmortems for incidents involving software that the developers wrote.
