Skills: You need to have high quality project management skills to win your battle. If you are leading a team of unbeatable and brave soldiers but lacking the same in you, would not lead you to a winning situation.
Tools: Whether it is project management tools, bug tracking tools or incident recording tools – you need to assess your needs and acquire these tools accordingly. Overstuffing yourself beyond required commodities will lead to a burden on your head. But vice versa also holds equally good meaning if you are underestimating your needs and go for the battle along with your team with shortage of armory, your defeat is sealed right in the beginning.
Experience: Guys with rich experience under their belt and laurels shining on their shirts are always moral boosters in the teams. Hence it is important to have such guys, at least one in each team to keep overall tempo at high pitch all the time.
