For example, they advise executives to do what they already want to do (layoffs and increased executive compensation) and thus justify that decision (blame outsourcing). A more generous take: when a business or project is stagnating due to bad management and communication, almost any advice that leads to change improves the situation. Especially when the situation is such due to some "principal actor" type issues, introducing more actors with different inscentives can rebalance things in the short term.
