  2. 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.

  3. Systems Development Life Cycle

  4. Rapid Application Development • This system is developed for each unique user. A custom system is created.

  5. Object Oriented Development • This system uses a series of pre-written diagramming techniques known as Unified Modeling Language

  6. System Definition Phase forAlternative 1 • Insert property information in system • Insert schedule and cost into system

  7. 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

  8. System Definition Phase forAlternative 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

  9. 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.

  10. 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.

  11. 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.
