Ability to adapt to change	In Agile model the changes are accepted and adapted as per the project needs.	But in non-Agile models the changes are not accepted easily in the later stages of the development.
Documentation required	Less documentation is required in Agile.	More documentation is required in non-Agile models.

Planning in Advance	There is minimal upfront planning in Agile methodology.	In Non-Agile models the planning should be complete before the development starts.
Revenue	In Agile method the return on investment is early in the project cycle.	In non-Agile methods the return on investment is at the end of the project.
Size of the team	The size of the team in Agile methodology is usually small and creative.	But in Non-Agile models the team size is large.
