ISDS 406 FINAL EXAM CSUF / ISDS 3115
FINAL – Complete Study Guide & Practice
Questions
What are the steps of the design phase? - Answer--1. Determine system aqcuisition
strategy (make, buy, outsource)
2. determine technical architecture for the system
3. address security concerns and globalization issues
4. make hardware and software selections
5.determine how users will interact with the system (interface, inputs, outputs)
6. design the programs for the underlying processes.
7. design the way data will be stored
8. create final deliverable (system specification)
What are three acquisition strategies? - Answer--make (custom development), buy,
outsource
what is the final deliverable? - Answer--system specification
how do we choose an acquisition strategy? - Answer--depends on what firm wants
pros and cons of custom development strategy - Answer--PROS: exactly what you
want, new system built consistently with existing tech, allow team flexibility and
creativity, unique solutions
CONS: time and effort consuming, may add to backlogs, requires skill, risk of project
failure.
, Pros and cons of buying software development strategy - Answer--PROS: no need to
reinvent the wheel, tested and proven product, time and cost efficient, vendor expertise,
some customization available
CONS: rarely a perfect fit, firm must adapt to process, reliance on vendor for
maintenance, may require system integration
pros and cons of outsource development - Answer--PROS: hire expertise we don't
have, may save time and money, lower risk, consultants specialize in system integration
CONS: reliance on vendor, future options limited, security- potential loss of confidential
info, performance based on contract terms
What is an RFP and it's purpose? - Answer--Request for proposal (RFP)
- solicits proposal from vendor, developer, or service provider and explains the system
to be built and criteria for selecting among applicants
What is an RFI and it's purpose? - Answer--Request for information (RFI)
- a shorter and less detailed version of RFP
What is an RFQ and it's purpose? - Answer--Request for quotation
-used when you just need a price
what is listed across the top row of an alternative matrix? - Answer--the different
acquisition strategies
what is listed in the first column of an alternative matrix? - Answer--technical issues,
criterion
how is the right alternative selected in a matrix? - Answer--highest weighted score
Architecture Design - Answer--Plans for how the system will be distributed across
computers and what hardware and software will be used for each computer.
what are the 2 major architectural components? - Answer--hardware and software
what are the 4 basic functions of software? - Answer--1. data storage
2. data access logic- processing required to access stored data
3. application logic- logic documented in the DFDs, use cases, and functional
requirements
4. presentation logic- display of info to user
