OnePager Pro Software Development Waterfall Project Plan Features

The project plan uses:

  • Grouping of each deliverable into swimlanes based on overall project phase.
  • Deadline markers to indicate which deliverables cannot slip
  • Display of budget information in row labels next to each project task.
  • Dynamic project legend that color codes every deliverable by the responsible resource or team.
  • Visual representation of the project's baseline schedule, progress (percent complete), and critical path.
  • Event links to show relationships between deliverables and phases.
  • Vertical curtains to block off parts of the project schedule impacted by code freezes.
  • Comment boxes to call out important events that impact the overall release schedule.

This software development waterfall schedule was created using OnePager Pro, Gantt Chart software that integrates with Microsoft Project.

This software development lifecycle plan was built using the following files, which you can download in either Microsoft Project or Excel format if you'd like to create something similar:

For Microsoft Project users:

For Excel users:


To build a software development lifecycle plan like the example above, follow these instructions:

  1. Download one set of the sample files listed above. The Microsoft Project and Excel files contain the actual software development plan, and the matching OnePager template file has all of the settings that drive the look and feel of the chart based on the data from either Project or Excel. Save both files to your desktop.

  2. Open the Microsoft Project or Excel plan.

  3. Once the project plan is open, go to Add-Ins and click the OnePager button.

  4. When the start screen appears, click NEW to build a new Gantt chart.

  5. Change OnePager's default template to the one downloaded above, making sure that you pick the template that matches the Microsoft Project or Excel plan that you downloaded. To do this, click on Change, and then BROWSE FILES to the OnePager template (*.tat) file. This OnePager template contains all of the data-driven formatting (colors, layout, etc.) that give this software development lifecycle plan its specific look.

    Use a Custom OnePager Template

  6. With the template loaded, click on Create New Project View to build your chart. It should closely match the example at the top of this article.
  7. To add comments or notes like the example above, left-click on any task or milestone and then go to Insert > Comments to add any additional information.
