A common language, an agreement on how to communicate effectively is the binding force that can bring people in a team together through shared understanding. A ‘how we work’ guide is useful to reinforce good behavior in the team, hold others accountable and spend time in doing real work as opposed to resolving issues that creep up due to lack of proper communication guidelines. A good playbook for your team should cover how we make decisions, how we work and how we react to decisions that require collaboration with others - a good decision-making process.
