Individual and interactions over process and tools
One of the Agile Manifesto principle says " Individual and interactions over process and tools " this needs to be practised on a daily basis to make it a habit. In a team, you can have team members of different behaviour, some talk less, some talk more and some try to hide their feelings. In such situations, it is the responsibility of Scrum Master to ensure team members are talking to each other and the conversations are happening. Scrum Master can do this by having casual, informal conversation and this would help team to collaborate often and this could minimize the issues. Encourage face to face conversation if possible. Another very important responsibility of Scrum master is to promote discussions which requires attention from other team members. Most of the project fails due to communication issues hence this principle must be taken very seriously and scrum master need to keep innovating the ways of handling this! How do you want to promote this principle
