Gantt chart that automatically distributes hours across multiple concurrent tasks, and automatically rolls over unprogressed tasks

Question

I'm not sure if a Gantt chart / Gantt software is the wrong tool for my use case, or I'm unaware of some technique / terminology.

Given (1) a set of tasks, (2) time estimated to complete each task, and (3) dependencies to other tasks, I want a view that shows when each task would be completed if a single resource were allocated evenly among all tasks.

Maybe easier to imagine: "Roughly how much can be accomplished by September given a 1-person team?"

So far I've played around with Teamweek and TeamGantt (advanced trial) with no luck. These seem to require manually assigning hours or tasks per day per resource, whereas I want that assignment done automatically, rolling over incomplete tasks (e.g. unexpected sick day) automatically as well, so that I always see a forecast of completion.

Are Gantt charts the wrong tool? Or is there some technique or term I'm missing?

Answer 1

Ah, I think I found my answer through one of the related questions: Project Management Gantt Tool makes All Tasks Concurrent .

It looks like what I'm trying to do is level resources (in my case, a single resource).

It's not available in TeamGantt for sure, and I don't believe in TeamWeek either.

As of June 29th, 2018, one of the commenters in that link states,

I tested more than 30 project management software and [only] found [resource leveling] in Gantter and MS Project.

Edit

Much easier to research now that I've found the term "resource leveling."

Wrike supposedly supports resource-leveling as "Workloads", but it costs over $65/month to get Gantt charts (for 5 users), and then more to get the Resource integration that introduces Workloads. Microsoft Project, in comparison, currently costs $30/month/user. So, I guess it depends.

If I understand your problem properly:

I think you would get the result you expect if you treat your resource as a task - I think most software would then handle it properly.
