I am looking for a good way to aid a service team head in assigning incoming tasks to his people. Tasks are scheduled for a certain week, not for exact days. Team members can take roughly 3-10 of this kind of tasks a week, and the tasks can vary in the effort they take.
The view should display the "workload" of all team members for one or multiple weeks, such that the team head can spot out the person with the least work load for that week and assign the task to that person.
However, it is overkill to define a capacity for each resource and week, and an effort measure for each task. The view should display the workload of each member in a way that does not suggest any "percentage" of "capacity", but you can quickly see how many tasks the member has already taken, and it should be very easy to get details about the tasks.
Do you have any idea or great examples for a chart/view that supports these requirements?
Clarification: There is no exact start/end date for tasks. Instead, a week is like a "pot", and roughly 3-10 tasks can go in that pot. It is irrelevant whether these tasks are carried out in parallel or one after the other.
We first considered something like the Outlook Scheduling Assistant which displays each resource in a row and the time in the x axis. Blue and white regions denote free/busy times. But this kind of view fails because "busy" means "100% workload", and because this free/busy information is bound to exact times of day.
I read up a bit on MS Project resource usage views but they include a percentage of "busy-ness" of a resource based on capacity and task effort numbers.
