There are various System Development Methodologies. These include but not limited to:
Waterfall
Agile
Dynamic Systems Development Method
Microsoft Solution Framework
Rapid Application Development

In your previous course work, you researched system development methodologies. 
Create a memo (400–600 words) that proposes the system development methodology
 that you would like your team to use. You must present your selection in a logical, clear, 
and compelling manner. To justify your selection, compare and contrast the methodology of choice 
with another methodology that is a viable alternative. This demonstrates that you have considered several options.
 Remember that in your upcoming group discussion, the team will need to select one methodology.
 If all proposals are written properly, the selection process will go smoothly.
