The statement, “the earlier we start a project, the earlier each project will get finished” is not true for multi project environments. (not only the first elephant, but also the last elephant will go through a door much faster if they go in a procession).

When too many projects are executed simultaneously, many resources will find themself under pressure to work on more then one task; Bad multitasking becomes unavoidable.

Prolific bad multitasking significantly prolongs each project’s lead time. Flow should be number one consideration in a multi project environment. The target should not be how many the projects the company succeeds to start working on, rather it is how many projects that are completed.
