The helicopter view basically means looking at the big picture, and not losing sight of the goal of the project because you’re so focused on just finishing it. Rosenhead suggests you check yourself at every team meeting. Look again at the original business case ideas and make sure you’re hitting the objectives.
Every team member needs to be honest about where they stand with the project. It may work to devise a scoring system based on the objectives and have each person report where they fall on that scale. Another solution could be a shared program (online being best, for the sake of anywhere usage) which allows for feedback from the team in a routine, repeatable way. The bottom line is, sometimes the project manager just needs to say no and let someone else handle certain details. This frees up more time for the helicopter view and increases your chances of accomplishing the end goal.
