I like when that happens. I grabbed a “random” book in the office, flicked through and it turned out to be a real gem. “The Trusted Advisor” by Tom Peters, David Maister, Charles Green and Robert Galford is unsurprisingly all about trusts. It talks about the role and importance of creating and sustaining trust for professional consultancy services. You can use it as a guide for building and evolving trust. It describes what it looks like when you experience a trust relationship and gives good reasons why trust is more important that technical excellence.
I really liked this book primarily because I attribute similar importance to trust. I also think it is still greatly underrated in both management and in IT industry but it is changing. Agile manifesto as well as XP both emphasize that software development is primarily about interaction between people (at all different levels) and about technical practices second. One of the principles behind Agile Manifesto explicitly refers to it: “Give them the environment and support they need, and trust them to get the job done.“
