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 Insert property information in system Insert schedule and cost into system

Systems Definition Phase for Alternative 2 Personnel Needed to develop system Manager IT personnel to develop the system Programmers Software testers User representatives to refine system and make it user- friendly System Analysts

System Definition Phase for Alternative 3 Personnel Needed to develop system Manager Systems Analyst Design and Implementation Database designer to develop entirely new system IT Personnel Programmers Software Testers Testing and Conversion Testers Business Users

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 user- based. 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.
