1.2.3 Flashcards
What occurs during the analysis stage if software development?
- stakeholders state their requirements
- the problem is defined
- system requirements are outlined
What occurs during the design stage of software development?
- different aspects of the system are designed
- a test plan is created
What occurs during the development stage of software development?
- the design is used to split the project into individual modules
- each module is developed
What happens during the testing stage of software development?
The program is tested against the test plan
What is alpha testing?
The system is tested by software developers in-house
What is beta testing?
The software is tested by end users
What is white box testing?
The test plan is based in the structure of the program
What is black box testing?
The user testing the program is not aware of the structure
What happens during the evaluation stage of software development?
The effectiveness of the software is evaluated against the system requirements
What is the waterfall lifecycle?
The stages of development are completed in sequence from start to finish
What is agile methodologies for software development?
- these make use of prototypes to constantly refine the system
What is extreme programming?
- 2 programmers and a representative of the end user work together in a team
- the sim is to produce high quality code
What is the spiral model?
- 4 key stages are looped with a focus on managing risk
- if risk is too much at any stage the project is ended
What are the advantages of using the waterfall lifecycle?
- straightforward to manage
- clearly documented
What are the disadvantages of using the waterfall lifecycle?
- lack of flexibility
- no risk analysis
- limited user involvement
When should the waterfall lifecycle be used?
- low risk projects
- static projects
- no need for user input
What are the advantages of agile programming?
- produces high quality code
- flexible to changing requirements
- regular user input
What are the disadvantages of agile programming?
- poor documentation
- requires consistent communication with user
When should agile programming be used?
- small to medium sized projects
- when initial user requirements are unclear
What are the advantages of extreme programming?
- produces high quality code
- high usability
What are the disadvantages of extreme programming?
- high cost of two programmers
- teamwork is essential
- end user may not be able to be present
When should extreme programming be used?
- when the initial requirements are unclear
- high usability is important
What are the advantages of the spiral model?
- manages risk well
- caters to chainring needs
What are the disadvantages of the spiral model?
- expensive for a risk manager
- lack of focus on code efficiency
- high costs to keep prototyping
When should the spiral model be used?
For high risk projects
