Mis541A System Analysis And Design

Front 1

What are Five Application development approaches?

Back 1

1. Waterfall Model
2. Prototyping Approach
3. Incremental Approach
4. Spiral Method
5. Rapid Application Development

Front 2

List pros for Waterfall model

Back 2

+ supports less experienced teams
+ orderly sequence
+ progress measurable

Front 3

List cons of Waterfall model

Back 3

- inflexible, costly, slow
- requires early identification of problems
- excessive documentation
- problems not discovered until system testing

Front 4

List pros for Prototyping approach

Back 4

+ useful for resolving unclear objectives
+ encourages flexibility
+ provides quick documentation
+ testing continually

Front 5

List cons of prototyping approach

Back 5

- less control and approval process
- possibility of inadequate problem analysis
- iterations may increase budget and schedule

Front 6

List pros of Incremental approach

Back 6

+ potential to exploit knowledge gained in earlier increments
+ provides evidence of project status frequently
+ delivers a series of implementation increasing in complexity

Front 7

List cons of Incremental approach

Back 7

- may lack overall consideration of bus. problem
- requires well defined interfaces between modules
- solves easy problems first, pushing back harder ones

Front 8

What is the framework for Prototyping?

Back 8

iterative

Front 9

What is the framework for waterfall?

Back 9

linear

Front 10

What is the framework for Incremental approach?

Back 10

iterative, incremental

Front 11

What is the framework for Spiral approach?

Back 11

combination of linear and iterative

Front 12

List pros of Spiral approach

Back 12

+ enhances risk avoidance
+ can incorporate waterfall, prototyping, and incremental approaches

Front 13

List of cons of Spiral approach

Back 13

+ complex management
+ highly customized to each project so limited reusability

Front 14

What are the four phases of Spiral approach?

Back 14

Determine objectives
Evaluate alternatives & Risks
Develop and verify
Plan next phases

Front 15

Draw each of the five development approaches

Front 16

What are the three main phases of Rapid Application development?

Back 16

Redesign, Reevaluate, Respecify

Front 17

What is the framework of Rapid Application development?

Back 17

iterative

Front 18

What are the pros of Rapid App development?

Back 18

+ quick deliverables
+ frequent evaluation and adjustment
+ documentation built from in-code comments

Front 19

List cons of Rapid App development

Back 19

+ little documentation
+ possibility of inadequate problem analysis

Front 20

List six principles of application development

Back 20

1. Adapt the process
2. Balance the competing stakeholders' priorities
3. Collaborate across teams
4. Demonstrate value iteratively
5. Elevate level of abstraction
6. Focus continuously on quality

Front 21

Explain how to decide which app developmental approach to select?

Back 21

consider project size, software complexity, # of stakeholders, time pressures, business constraints, affordability of tools
