6. Rely on Your Team; Avoid Strangling Your Best Assistant
Harry’s collaborative skills tip the scales back in his favor. Both he and Voldemort have considerable human resources.
Voldemort has the Death Eaters—especially the Malfoys—the dementors, Bellatrix Lestrange, and Wormtail. He also has the trolls and giants lined up on his side. Voldemort does a poor job of trusting and communicating with his subordinates, however. Loyalty is a rough commodity in his camp. Perhaps his most faithful follower has been Wormtail, who is strangled by the very hand that Voldemort gave him. Ultimately, the Big V murders Snape not because he suspects him of double-cross but because he wants to become master of the Elder Wand.
As if that's not enough, he also has made the mistake of punishing Lucius Malfoy (for his earlier failure to secure the prophecy) by assigning Draco to kill Dumbledore. Altogether, this demonstrates such very bad technique for motivating team members—probably leading to his final downfall, which begins when Narcissa Malfoy tells him that Harry is dead.
Harry’s team includes not only his two best friends, but also the Hogwarts staff, the Order of the Phoenix, and Dumbledore’s Army. The elves work with him, and he has some limited cooperation from goblins and centaurs. All factions cooperate and communicate well, a key factor in any successful project. Harry works hard to make certain that everyone feels appreciated. Even the weakest project processes can be overcome by teamwork. In the end, of course, there’s nothing like Harry’s remarkable collaboration and teamwork skills, and that's what finally tips the scales in his favor.
From Harry we learn the benefits of interacting with each of our various team members to keep them interested and at peak performance.
