Microsoft Project Calculates 2 hours as .5 days and 4 hours as 1 day. Why?

Hello All,

I think my questions may be a simple ones. I am creating a project plan with MS project. I am a beginner with project as ive used other tools in the past.

I have 8 hours set as one day and 40 hours set as one week. I also have my project set to display my duration column as hours not days. With all of this I have several issues:

-Even though I want to see duration in hours only, some rows dont recalculate in hours. They are stuck in days. How do I fix?

-Some work hours roll up to durations that arent accurate. So not only is it not just pushing the hours into the duration column, it is also calulating 2 hours as .5 days for example.

Another question is, why do some of my hours have a ? next to it?

Finally, is there a way to have project take my start and end dates, then take a guess at assigning my project to the work days in between my start and end?

Thanks in advance

-CH

Hi,

this is many questions in one :)

The easy one first: the ? is always shown after entering a new task to indicate that the duration has been set to the default of 1day and is an estimated duration. As soon as you enter a duration, the ? goes away.

Have you set the Options..Schedule to show "Hours" for the duration? Be aware that there are 2 ways to set the option: "All new projects" or "Project1". If you choose "All new projects", the setting for "Hours" will apply to all tasks in all new projects which seems to be what you are looking for. However, any tasks that have been created with the "wrong" setting of "Days" will keep this setting unless they are summary tasks.

What do you mean by "Some work hours roll up to durations that arent accurate" ? Have you assigned resources to the tasks? Depending on the task type there is NO direct recalculation between work and duration, e.g. you can plan 10 hours of work during 5 days of duration (which is very common in scheduling).

The last part also leaves space for interpretation: do you want to set the project start date (yes, you do this in the "Project Information" window in the "Project" ribbon) and define the latest date for the project end? How should the tool "guess" what tasks you need?

Regards

Thomas
