We’ll put the start time on the left and the finish time on the right. To do this, go to Home > Project View Properties > Task Bars and check the Date Label Properties button. For added precision, our next step is to show the exact start/finish times as text.

This means that any task, no matter how short, will always show up as a task in OnePager:

If you want OnePager to show the entire duration of each task instead of rounding things off to a milestone, go to Home > Project View Properties > Advanced and set the Task/Milestone Threshold to zero days: This gets us closer to an hourly Gantt chart, but we still have to contend with Project and OnePager treating the tasks as milestones because they are less than a day: Next, we can right-click on the time axis and change it to show hours instead of days: Then, we can flip over to Project View Properties > Main and reduce the overall duration of the Gantt chart to just a few hours–all on the same day: This will tell OnePager to operate in time mode instead of date mode. To change this, we’ll first go to Home > Project View Properties > Advanced, check the Format with Times box, and click Apply. When we first build a OnePager chart, the five items come in, but we’re showing too much duration overall, so they’re very compressed: Each task in our simple project plan is scheduled on the same day, but at different times, and each for pretty short duration: You can set this up in either Microsoft Project or Excel, but we’ll use Project in this example. However, by changing a few simple settings in OnePager, you can create a very clean Gantt chart displaying times instead of dates: Microsoft Project–and yes, OnePager–has a tendency to treat shorter-duration tasks as milestones, which can fail to give you the hour-by-hour or minute-by-minute detail that you might need in your project report. In the IT space, many release management projects take less than a day to complete, and have many important details in between. Most project managers work with medium-to-long-range projects, and use OnePager to manage tasks on a day-by-day basis.
