Roadmap View

The bar associated with the task determines the duration for which the task has to be executed. It depends on the following parameters:
1) Estimate given to the work item during its creation.
2) Time spent on the task. Time spent can be entered directly if a scrum template is selected,else the time entered in the time tracking tab is summed up and obtained in case of traditional planning. The time spent field is non-editable in case of a traditional planning,but can be edited when one makes changes in the time tracking tab. Time tracking tab allows the user to enter the logged in hours on every day basis.
3) Availability of the user for the project. Check the availability of the user under the Work environment tab and look for the percentage in project allocations. This will give the amount of time the user can spare for a project. Also, check for the number of hours the user works everyday(Workday length and quitting time) and if there are any scheduled absences.

Once all the above factors are taken into consideration, it is easy to understand why the bar which is scheduled for hours takes days and that scheduled for days spans in weeks.
