Baker, Barker, Bickel IS Chapter 10 Presented by: Group D Wesley Ortiz, Michael Bury, David Nguyen and Kurt Cannarella

For alternatives 1-3, which system methodology applies to each ? For numbers 1 and 2 SDLC (Systems Development Life Cycle) applies to these alternatives because they would be based on a system (email) that has already been established. RAD (Rapid Application Development) and OOD (Object Oriented Development) apply to scenario 3 since it is based on a customized program based on the needs of the partners organization.

Systems Development Life Cycle

Rapid Application Development Customized for the users The design is broken up into smaller chunks instead of building the system all at once

Object Oriented Development It uses the Unified Modeling Language (UML), a series of diagramming techniques that are pre-written.

Compare Alternative 1 to Phase one of SDLC Have property info easily available and inserted Have scheduling/cost options available From info given during phase 1 plan accordingly

Steps required for alternative 2 Firstly, Baker Barker and Bickel must define their goals and what they hope to accomplish -In this case being achieving a competitive advantage and solving their customer problem Secondly, they must eliminate non-sensible projects -Such as the cost limitations of developing the system. -What is the schedule or time frame they hope to have the system completed. -Whether the system would be legally achievable.

Steps required for alternative 2 (continued) Personnel Needed: -Systems Analyst who understands both Business and Technology related fields. Design Stage -Program Design would be used because they're choosing to utilize “off-the-shelf” licensed software already existing. System Testing -Use a Test Plan in which the users will use every line of program code to test for errors.

Steps required for alternative 3 -Using (SDLC) Personnel Needed -Systems Analyst -Database Designer because entirely new system is being constructed. Design Stage -The developers are constructing a database thus they would convert the data model to a “Database Design” The Database would undergo a rigorous “Test Plan” to uncover any errors. Then move onto a “Phased Installation” to be sure that each portion of the program is operation correctly.

Difference between SDLC and RAD for Alternative 3 Prefer to use a mix of both system types The email system is already established and easy to use RAD provides small amount of customization Caters to the use of the business using different applications not available in e-mail
