To access the Spreadsheet project management tools, log into your Google Docs account. Select New - > From template... from the menu bar.
In the menu to the right, select Calendars & Schedules, and then type “projects" into the search box at the top. Click Search Templates.
You'll be given three templates to choose from. Select the one that best fits the needs of your project, and your team. Preview lets you see a sample of the template. To select the template you'd like to use click Use this template.
The Project Timeline template most resembles the familiar Gantt chart. For our demonstration purposes, that's the one we'll use.
Double click in the box which holds the project name. Highlight the sample name, and type the name of your project.
Double click in the Planning Phase box, and rename this phase as suits your project.
Double click Task 1 to define that task by name, then Tab over to the owner column and assign a person responsible for this task. Finally, Tab to the Duration column and designate a time expectation for the task. Repeat this procedure for each Task in the Phase. Now, repeat for each phase of your project.
To add additional tasks, click the last task in your list and select Insert - > Row below from the tool menu.
