Add Functional Groups
Before we decide on how the dependencies need to be modified, let us think of grouping the tasks functionally.
We know that the last two tasks, "Organize accommodation" and "Organize Travel" are both Admin tasks. To group these two, follow these steps:
1) First insert a new task before Organize accommodation, and name this task as "Admin" with a duration of 0 (zero) days.
2) Now, highlight both the admin tasks (Accommodation and Travel). (Hint: For highlighting multiple tasks, using the keyboard point to the task name of the first cell, in this case "Organize accommodation". Then, keeping the Shift key pressed, move down with the arrow key till the last cell, in this case "Organize Travel.")
3) On the Formatting Toolbar, click on the icon showing a Right Arrow (if you move the mouse over this icon, you can see the Tip as "Indent").
4) You will notice that the two task names have moved to the right (this process is called Indenting). The task name for Admin appears in Bold font to indicate that this is a Group task (a summary of the following tasks). The task bar against the summary "Admin" has changed to a Black bar covering all tasks in its group.
Next, you should group the five tasks from "Get rates from media agencies" to "Sell tickets" and call the Group "Sales & Marketing." Similarly, group the first six tasks from "Call up Artists" to "Confirm Auditorium" and call the Group "Operations." Let us also introduce a super-group covering all groups, and call this "Concert Project." (For this, Insert a task above Operations and name this task "Concert Project." Then highlight all rows below this and Indent them. With this it becomes a higher level Group.)
