Steve McConnell continues to describe the 28 key principles in his new book, More Effective Agile (Construx Press, 2019). The principles described this time:"Express Clear Purpose with Commander’s Intent." Support your teams’ ability to make timely, local decisions by clearly communicating your objectives for the desired end state. (See page 220 in the book.)"Model Key Agile Behaviors." Effective leaders model the behaviors they want to see in others. (See page 224.)"Manage to Outcomes, Not Details." Support your team’s Autonomy by clearly communicating desired outcomes while leaving the team free to define the detailed means by which it completes its work. (See page 219.)
