Assign tasks to developers and change the plans when something unexpected comes up.Making this as easy as possible leaves you more time to enjoy life outside your IT project management job.
It's important to cut costs when you're just starting out. If you have a small team up to 5 people,you can use Teamweek for free.
If plans change, drag and drop everything to another place. Set milestones, so you'd knowwhen you're running out of time and need to reprioritize.
Hold cmd (or control on PC) when dragging and dropping to duplicate the task.
