Do not undersell yourself on this idea. Every business has some form of task/project management. It is a booming field. I am assuming duration is 'expected time to complete task.' If I am assigned a task, I generally report how much time I spent on the task. A duration works in some situations, but time spent is usually what I am interested in when it comes to business oriented tasks. Each month-end I have to do certain activities, remind me and let me easily document that January took 1 hour, February took 30 minutes, and March took 6 hours (probably an issue in quarter-end processing!). Merge the idea of task manager and time manager to result in a project manager! There are huge profits in this business. Multiple users on the same task, gathering metrics, making graphs, segmenting tasks (verb1, verb2, verb3), showing cost center distribution, etc.
