Wow! These are challenging questions!
The book is about introducing new ideas and the target audience is "powerless leaders." I'm not sure it will help with management of teams.
Having said that, if the "idea" you want to "introduce" is "collaboration" -- to address the problem of the two members who do not seem to want to work together -- you could try some of the
patterns. For example, Just Do It, that is, collaborate with these team members and, in working with them, show them the benefits.
It's a related process topic that you might introduce Scrum, an agile method. Scrum includes a daily Scrum meeting. I have seen this simple practice bring reluctant team members to the table to cooperate because they can see the result of the information
exchange in the daily meeting. This is how you could Just Do It.

Good luck!
