MIS 375 FINAL EXAM STUDY GUIDE
In System Analysis we Figure out... - Answer -What the business needs
In System Deisgn we figure out... - Answer -How to build the system that fulfills those
needs
Design Phase - Answer --Decide how to build the system
-Create system requirements that describe all technical details for building the system
System Specification - Answer --Final deliverable from design phase
-Conveys exactly what system the development team will implement during the
implementation phase
Design Phase Steps - Answer -Determine system acquisition strategy (make, buy, or
outsource)
Determine the technical architecture for the system
Address security concerns and globalization issues
Make hardware and software selections
Determine the way that users will interact with the system (interface, inputs, and
outputs)
Design the programs for the underlying processes
Design the way data will be stored
Create final deliverable - the system specification
Elements of System Specification - Answer -1. Recommended System Acquisition
Strategy
2. System Acquisition Weighted Alternative Matrix
3. Architecture Design
4. Hardware and Software Specification
5. Interface Design
6. Physical Process Model
7. Program Design Specifications
8. Physical Data Model
9. Data Storage Design
10. Updated CRUD Matrix
11. Updated CASE Repository Entries
System Acquisition Strategies - Answer --Custom Development (build from scratch) in-
house
-Purchase Software Package
-Outsource Development to third party
, Systems Integration - Answer -Building systems by combining packages, existing
(legacy) systems, and custom software written for integration
Integrating data between various parts of the system is the key challenge
Many consultants specialize in systems integration
Outsourcing Contrats - Answer --Time and Arrangements
-Fixed-Price
-Value-added
Outsourcing Guidelines - Answer -Keep lines of communication open
Define and stabilize requirements before signing the contract
View the relationship as a partnership
Select vendor, developer, or provider carefully
Assign someone to manage the relationship
Don't outsource what you don't understand
Emphasize flexible requirements, long-term relationships, and short-term contracts
Request for Proposal (RFP) - Answer --Solicits proposals from vendor, developer, or
service
-Explains the system to be built and criteria for selecting among applicants
Request for Information (RFI) - Answer --a shorter and less detailed version of RFP
Request for Quote (RFQ) - Answer -use when you just need a price
Request for Proposal Contents - Answer -Description of desired system
Special technical needs or circumstances
Evaluation criteria
Instructions on how to respond
Desired schedule
Other information that will help the submitter to make a more complete or accurate
proposal
Alternative Matrix - Answer -combines several feasibility analyses into one matrix
Architecture Design - Answer -Plans for how the system will be distributed across
computers and what hardware and software will be used for each computer.
Hardware and Software Specification - Answer -Describes the hardware/software
components in detail to aid those responsible for purchasing those products.
