Management is aboutoverseeing a group to achieve an objective. A manager must define the goals of a project, break it up into tasks, assign responsibilities, measure individual & group progress and control the scope of the project to complete the work properly.
Managers were true that those are not necessarily good leaders. On the other hand, good leaders who maintain moral and motivation but aren’t good managers (scope, task, quality) also don’t produce great results. That’s why good leaders and managers should be paired.
