Flashcards in Information Management and BI 2(b) - SAELC Deck (13):
1

Under "System Acquisition and Evaluation Life Cycle", name the 3 Phases and cycles under each phase:

Phase 1: (BISD)
(1) Business Case
(2) Info Requirements
(3) Solution Selection
(4) System Design

Phase 2: (DQI)
(1) System Development
(2) Quality Control
(3) Solution Implementation

Phase 3: (TT)
(1) Training
(2) Transition

2

Under the "System Acquisition and Evaluation Life Cycle", what is involved in Phase 1, Function 1?

- "Business Case" is the 1 (of 4) Function under Phase 1
(1) Mgr requests new or change to existing apps w/ a Business Case
(2) Business Case then evaluated based on BoD guidelines

3

Under "System Acquisition and Evaluation Life Cycle", what is involved in thorough "Info Requirements Analysis" (Phase 1, Function 2):

- "Info Requirements Analysis" is the 2 (of 4) Function under Phase 1
- Systems analysts performs:
1. Interview end users and project sponsor
- Determine info needs
- Review existing business processes, existing apps, outputs or proposed outputs
2. Ensures security specialist scrutinizes proposal, and considerations for BI data that s/b captured that might not be recognized.
3. Captures 3 requirements:
(i) Business environment
(ii) Functional
(iii) Business process

4

Under the "System Acquisition and Evaluation Life Cycle", what is included in a "Business Case" (the 1st Function) under Phase 1:

- In Business Case, proposal outlined w/:
(1) Need, supported by high-level or business, functional,
(2) Tech requirements
(3) Describe proposed solution doc
(4) Decision-making factors (ROI)
(5) Strategic alignment evaluation

5

Under "System Acquisition and Evaluation Life Cycle", what is involved in "Solution Selection" (Phase 1, Function 3):

- "Solution Selection" is the 3 (of 4) Function under Phase 1
(1) Review alternative solutions (after complete req'mts doc and vet w/ key stakeholders)
(2) Solution selection could be:
(a) build or (b) buy - if buy, still several alt solutions
(3) Alternative solutions could take info requirements doc and create RFP for vendors to propose
(4) Perform due diligence w/ vendor proposals to make best choice

6

Under "System Acquisition and Evaluation Life Cycle", name the 4 cycles under Phase 1:

Phase 1: (BISD)
1. Business Case
2. Information Requirements
3. Solution Selection
4. System Design

7

Under "System Acquisition and Evaluation Life Cycle", what is involved in Phase 2:

Phase 2: (DQI)
(1) System Development
(2) Quality Control
(3) Solution Implementation

- System development process begins with a thorough information requirements analysis
-Takes "System Design" or vendor choice from RFP and perform due diligence before implement
-"SysDev or AppDev" involves turning system design into a solution, ready to test process and then implementation

8

Under "System Acquisition and Evaluation Life Cycle", name the 3 cycles under Phase 2

Phase 2: (DQI)
1. System Development
2. Quality Control
3. Solution Implementation

9

Under "System Acquisition and Evaluation Life Cycle", what is involved in Testing under "System Development" (Phase 2, Function 1)?

Application s/b tested:
(1) Alone
(2) By end user, project sponsor for functionality and errors
(3) With other apps it regularly interfaces
(4) In whole accounting cycle, if multiple modules in the cycle
(4) With GL, enterprise apps and databases
(5) Use simulator or staging area that replicates system in terms of platform, OS, all relevant apps, and relevant databases
3. Follow test plan w/ different scenarios.
4. Test controls, at least key controls

10

Under "System Acquisition and Evaluation Life Cycle", what is involved in Phase 3?

Phase 3: (TT)
(1) Training
- Reduce risk of failures in business processes, and errors in data entry
(2) Transition

11

Under "System Acquisition and Evaluation Life Cycle", What are 3 "Transition" conversion choices (Phase 3, Function 2)?

- Transition is the 2 (of 2) Function under Phase 3, - Transition choices are:
(1) Cutover
- Turn old system off and new on immediately
- High risk of problems
- All systems could be affected by a failure
- No going back to old system w/out cost and difficulty
(2) Parallel
- Old and new system are run simultaneous through a time frame
- Risks of failures minimized
- Cost of transition is highest
(3) Phased
- Mix of the two
- One unit chosen as "beta" where cutover approach used
- Risk is limited to that one unit

12

What is "System Solution Mgmt" (SSM)?

- SSM is similar to "Systems Dev Life Cycle" (SDLC)
- Purpose of SSM is to ensure quality in systems dev and deployment
- Ensure apps have appropriate controls and errors/risks are minimized

13

What is the business purpose of "System Solution Mgmt"?

- Ensure system aligns w/ business model, strategic plans, and enterprise goals
- SSM should lead to selection of solution that fits business processes and effective in aligning w/ strategies
