W$2$: DOTMLPF Issues

For this week's discussion, you have four tasks to perform:

$1)$ Explain the capability areas, which make up DOTMLPF.

$2)$ After reviewing the PowerPoint presentation for the week, what are some key roles of the PM and key issues facing the PM today $($I don't need all $11$ roles posted, just pass me your thoughts and findings from research$)?$

$3)$ How does one become a PM; what are the criteria? And what are the barriers to becoming a PM$?$

To get full credit on these posts, your answers need to be thorough and detailed. Go beyond the book answer and put in some of your thoughts.
