SLR 6

Question 1

What is feasibility?

Answer 1

Is the plan solvable?

Question 2

What are requirements?

Answer 2

Working out what the solution needs to do

Question 3

What is analysis and design?

Answer 3

Working out how the solution needs to do something

Question 4

What is implementation?

Answer 4

Coding the solution

Question 5

What is testing?

Answer 5

Checking the product actually works

Question 6

What is deployment?

Answer 6

Installing it in the target environment

Question 7

What is evaluation?

Answer 7

Checking in with the user to see if the solution is complete

Question 8

What is maintenance?

Answer 8

Continuing to ensure it functions and make improvements, patches and updates

Question 9

What are the types of methodologies?

Answer 9

Waterfall
Rapid Application Development
Spiral
Agile
Extreme programming

Question 10

What is the waterfall life cycle?

Answer 10

Gets its name from cascading from 1 phase to another

Each phase has a designed start and end

Question 11

What is the RAD development cycle?

Answer 11

Involves producing successive prototypes of the software until a final version is finished and approved

Question 12

What is the spiral model?

Answer 12

A risk driven development cycle involving some unique risks

Acts as a guide for development teams, adopting elements from waterfall and RAD

Decisions made off of identified risks

Question 13

What is the agile methodology?

Answer 13

Refers to a group of methodologies

More refined that RAD

Built in a series of iterations known as sprints which are start time boxed periods which focus on set goals

Each sprint should be short and take less than 4 weeks

Question 14

What is extreme programming?

Answer 14

Aims to produce high quality code and promote the QOL of developers

Follows: Simplicity, communication, feedback, courage and respect

It is considered an agile framework and aims to show every member of the team is of equal value

Question 15

What are the benefits of waterfall?

Answer 15

Simple, easy to manage
Everybody has clear responsibilities
Clear deliverables
Easy to see if project is up to schedule

Question 16

What are the risks of waterfall?

Answer 16

User can’t see project until it’s finished

Can lead to unfixable projects if there is a misunderstanding

Requirements must be understood, so bad for complex projects

Question 17

What are the benefits of RAD?

Answer 17

Requirements don’t need to be clear at the start

Can gather requirements without any large documents

Continuous feedback, excellent usability

Question 18

What are the risks of RAD?

Answer 18

Not useful for projects that require code efficiency

Constant contact with client needed

Scales poorly for large projects

Question 19

What are the benefits of Spiral?

Answer 19

Risk management

Excellent for high risk projects

Question 20

What are the risks of Spiral?

Answer 20

Complex nature of risk analysis leads to high costs

If risk analysis is bad then the project will suffer

Question 21

What are the benefits of agile?

Answer 21

Emphasis programming means end product is high quality

Core principles, productive development team

Question 22

What are the risks of Agile?

Answer 22

Requires team to be geographically close

Client must commit full time

Cost

Question 23

What is an algorithm?

Answer 23

A sequence of steps to complete a task

Flowcharts can represent algorithms and pseudocode can be used to use logic but ignore rules and syntax

Question 24

What is black box testing?

Answer 24

Checks whether an input gives an expected outcome or not

Question 25

What is white box testing?

Answer 25

Testing algorithms to make sure they work as intended

Checks all possible outcomes and the codes overall efficiency

Question 26

What is alpha testing?

Answer 26

When a developer hires a friend or family member to test a program

Question 27

What is beta testing?

Answer 27

Letting a large variety of people test a program
