Introduction to IT & Telecoms Systems Development – Outcome 2

Question 1 of 10

1. Question

Category: Describe top down, bottom up and integrated approaches to systems development

What is meant by a ‘Top-Down’ approach to software development?

Emphasis is on planning and understanding the system. Development does not begin until a sufficiently detailed knowledge of the system has been reached
The developers plans for a while and the makes an attempt at designing a system
Development begins immediately without any planning or forethought
The developer raises the height of his chair so that he can view his monitor from the 'top down'

2. Question

Category: Describe top down, bottom up and integrated approaches to systems development

What is meant by a ‘Bottom-Up’ approach to software development?

The developer lies on the floor so that he can view his monitor from the 'bottom up'
The base elements of the project are specified in great details and emphasis is put on development and early testing
Development is delayed for a long time due to lack of planning
There is a greater emphasis on planning in 'bottom up' than there is in 'top down'

Question 3 of 10

3. Question

Category: Describe top down, bottom up and integrated approaches to systems development

What is an ‘integrated’ approach?

When lots of designers work together
When the end user tests the system
When individual modules are combined and tested as a group
When new staff members are employed to work on a difficult system

Question 4 of 10

4. Question

Category: The purposes of the initiation, analysis, design and implementation phases of the IT SDLC

What is the ‘initiation’ phase of project?

What developers call their first day
When approval is given and the project is given the funding and resources to proceed
It's the very last stage of a project
It's the same as the analysis stage

Question 5 of 10

5. Question

Category: The purposes of the initiation, analysis, design and implementation phases of the IT SDLC

What is the ‘analysis’ phase of a project?

The analysis phase defines the requirements of the system as requested by the customer
The analysis phase is the first stage of the project
It's also called the design phase
It's when the designers all sit around contemplating deciding what to do first

Question 6 of 10

6. Question

Category: The purposes of the initiation, analysis, design and implementation phases of the IT SDLC

What is the ‘design’ phase of a project?

It's sometimes known as the implementation phase
It's when they meet with the customer to talk about the system
It's when the designers plan how best to implement the customer's requirements
It's when the program is completed and tested

Question 7 of 10

7. Question

Category: The purposes of the initiation, analysis, design and implementation phases of the IT SDLC

What is the ‘implementation’ phase of a project?

It's when the system is constructed, normally starting with small modules and gradually integrating them into a complete system
It's the very first phase of a design project
It's also known as the Initiation phase
It's when the designers decide on the layout

Question 8 of 10

8. Question

Category: The advantages and disadvantages of the traditional (‘waterfall’) SDLC model

What are the advantages of the traditional (‘waterfall’) SDLC model?

It allows for departmentalization and managerial control. Deadlines and time-scales can easily be set and managed
It's the most cost effective
It's great for huge complicated projects
It's easy to go back and change things that weren't well thought out

Question 9 of 10

9. Question

Category: The advantages and disadvantages of the traditional (‘waterfall’) SDLC model

What are the disadvantages of the traditional (‘waterfall’) SDLC model?

It's expensive
It's complicated
It's not easy to back track and change things that weren't well thought out or to make revisions
It's not great for straight forward projects

Question 10 of 10

10. Question

Category: Other SDLC Models

When would you use the ‘The Spiral Model’?

On small, simple projects
On medium sized projects
On large, expensive, and complicated projects
On relatively inexpensive projects
