Which system methodology applies to
each alternative?


SDLC (Systems Development Life Cycle) applies to
alternatives 1 and 2 because they would be using
an already developed system, e-mail, and not
developing any new systems.
Alternative 3 uses RAD (Rapid Application
Development) and OOD (Object Oriented
Development) because it requires a new, custom
program and cannot use one that has already been
developed.
Systems Development Life Cycle
Rapid Application Development

This system is developed for each unique user. A
custom system is created.
Object Oriented Development

This system uses a
series of pre-written
diagramming
techniques known as
Unified Modeling
Language
System Definition Phase for
Alternative 1



information in system
Insert schedule and
cost into system

Using RAD Instead of SDLC




RAD breaks up the design and implementation
stages of the SDLC into smaller chunks.
These chunks are implemented using as much
computer assistance as possible.
RAD requirements analysis can be less detailed and
less complete than with SDLC because it relies on
computers and not actual users.
I would recommend SDLC because it is more userbased. It is difficult to have a computer predict how
a human will be able to use the system.
Which Makes the Most Sense?

Out of the three alternatives, I feel Alternative 2 makes
the most sense because:
It is a more complex, thorough system than just simply
e-mail
 It will not be as expensive as developing a brand new
system.
 By using an existing application, you can be confident that
the system in place works and you will not have to keep
modifying the system until it is acceptable.


Other information you might need would include the
price of a new system, the price to buy an existing
system, and user reviews on existing systems to make
sure they are user-friendly and work properly.
How to Communicate These Ideas?

Which of these tools would be most appropriate for the
company: Google Docs and Spreadsheets, Microsoft
Groove, or Microsoft Sharepoint?
Microsoft Groove would be the most appropriate. This gives
each user the same access and limits to the information.
 Google Docs & Spreadsheets simply is not enough to run the
entire operation on.
 Microsoft Sharepoint can limit user controls. In a
collaboration, each party should have full access to the
information. With Sharepoint, a user can limit what the other
partners can see, causing friction within the partnership.
