[Planner] Tasks assigned to same resource scheduled concurrently?

[Roberto Leibman]

It's funny that what's perfectly obvious to someone new to project 
management is ignored by most experts.

I have to agree with Josep that any tool that does project management 
has to make resource constraints a first-order problem, and not an 
afterthought. I've yet to see any widely used tool that does this; 
Primavera, MS Project, etc don't do it, they all require you to go 
through hoops to do resource leveling and most of the time you end up 
having to create artificial temporal dependencies such as the suggestion 
given to Josep. These dependencies are at best a workaround, but in 
practice they can be detrimental to the project because they obscure the 
possibility of doing tasks in parallel by the "simple" addition of 
resources to a task, in practice, as the project progresses you figure 
out that the link is artificial and often end up doing the task in 
parallel anyway, thereby throwing your hands in the air and saying: 
"screw this project plan", or even worse, spending another couple of 
hours redoing the whole thing (and then an hour's meeting explaining the 
"new and improved" project plan to the team.

Which is why there exist better methodologies than Critical Path 
analysis (yeah, I know, I repeat myself) such as Critical Chain 
management, that take into account resource constraints from the beginning.
