For you to be an effective team leader, you have to trust your colleagues and believe in their abilities. That means not forcing them to follow a script or do things your way.
A team leader is also expected to make decisions that will influence the outcome of individual team member tasks. The first step of decision-making is identifying a need for an intervention. For example, if there’s a disagreement, the manager has to intervene and make a decision to cool both parties down.
An effective manager tries to encourage everybody to work together and have synergy. In the process, they can put individuals that have supplementary skills in the same team. For example, someone with Python programming skills can complement another programmer with Java skills.
If the manager is successful with building synergy, team members will become more open with each other. They’ll send each other messages and exchange notes.
Even though decision-making should be based on factual information, sometimes it may not be readily available. In that case, the manager can use their intuition and experience to speed up the decision-making process.
Today, teamwork is widely used in US companies because it leads to better productivity. But things were not always this way. Companies used the human relations school of thought but rarely relied on teamwork. It was after Toyota’s and GM’s joint venture in 1983 that US companies began to appreciate the value of a work team.
