Software Development

Question 1

Give methods used by software companies to develop

Answer 1

(Iterative/waterfall) and (agile)

Question 2

Give advantages why Agile method might be used

Answer 2

1. The client is constantly involved through out the process giving constant feedback
2. Teams of developers communicate and collaborate
3. You get fast face to face communication during the project
4. Reducing documentation this allows to spend more time on small cycle of coding and testing
5. You can adapt very quickly when needed to change something in the project
6. No testing phase everything gets tested at the moment

Question 3

Give advantages of Iterative/waterfall method

Answer 3

1. Client is heavily involved at the start and end points of development and there is a fixed plan to be followed by the develop team.
2. Teams of analysts, programmers, testers and documenters work independently on each phase of development.
3. Testing is carried out when the implementation phase of the project is complete.
4. Follows a strict plan, with progress measured against timescales set at the beginning of the project.

Question 4

What are the parts of analysis you need to know about?

Answer 4

1. Purpose
2. Scope
3. Boundaris
4. Function requirements

Question 5

Give the meaning of Purpose?

Answer 5

Description of the purpose of the software

Question 6

Give meaning of Scope

Answer 6

A list of Deliverables that the project will hand over to the client
for example(completed program, test plan, test results and evaluation report. It can also include any time limits for the project)

Question 7

Give meaning of boundaries

Answer 7

The limits that help define what is the project and what it is not.

Question 8

Give meaning of Functional Requirements

Answer 8

The features and functions that must be delivered by the system in terms of inputs, processes and outputs.

Question 9

How would a User interface be designed

Answer 9

By wireframe

Question 10

How would a program structure be designed

Answer 10

1. Flowchart
2. structure diagram
3. Data flow
4. Pseudocode

Question 11

what is data flow

Answer 11

Data flow is what parameters are being passed in and out of each subprogram

Question 12

What is created at the implementation

Answer 12

User interface and code

Question 13

What is modular code?

Answer 13

Code that uses procedures and functions

Question 14

What benefits does Modular Code has ?

Answer 14

1. Projects can be split between teams of programmers
2. Sub-programs make code easier to read
3. .Easier to maintain
4. easier to debug

Question 15

What are advantages of pre-defined functions?

Answer 15

Saves time because the code has alredy been written, therefor programmers have less code to create.

Question 16

What is the difference between functions and procedures?

Answer 16

The function returns value to the main program but procurers perform a specific task.
