Retrieval practice software development methodologies #6

1 Which of these is not a commonly-used fact finding method when the development of a new IT system is being investigated?

• A. Observing employees in the workplace doing their jobs
• B. Using actors as customers to provoke reactions from employees
• C. Interviewing employees face to face
• D. Circulating questionnaires to employees

2 Explain what is meant by a "stakeholder" when a new IT system is being developed

• A. This is another word for a customer
• B. This is a manager or other member of staff who will use the IT system directly
• C. This is someone in a position of authority such as a financial lender who has ownership over the business, or any member of senior management within the business
• D. This is someone who will be affected by the development of the IT system and may need to play an active role in its design

3 Projects involving the development of new IT systems often fail. Which of these is not a common reason for IT system development project failure?

• A. Algorithmic
• B. Economic
• C. Legal
• D. Technical

4 Which of these is not found in the requirements specification for a new system?

• A. Normalisation and data dictionaries for database components
• B. Input, processing and output requirements
• C. Minimum hardware and software specifications
• D. Client consent to all stated requirements

5 Which of these best describes the contents of high-quality user documentation?

• A. Acts as a "Getting Started" guide, like an instruction manual included with a new item of hardware
• B. Covers technical aspects of the system such as the hardware specification, the file formats, security aspects and the meaning of error codes
• C. Explains how to use, maintain, back up and troubleshoot a system, often including a glossary of key words that a new user might need to look up
• D. Focuses on mapping out the system as a whole using diagrams, algorithms and flowcharts to express how the system actually processes the data and how its modules interoperate. It provides a detailed breakdowof the algorithms for each module.

6 Systems must be evaluated to determine..

• A. Whether the client is satisfied with what they have purchased before the developer hands over responsibility for maintenance to the client and the developer discontinues any involvement A
• B. Whether the developer correctly guessed the user's requirements at the start of the project so that they can learn from any mistakes and oversights before they proceed to their next project
• C. Whether the system still meets the user's requirements in terms of its performance, ease of use, stability/robustness and cost effectiveness, given that user requirements change over time
• D. Where bugs exist in the system so that ty can be fixed and the system can work as intended

7 Which of these applies to the waterfall model of system development?

• A. Stages can be done in parallel to each other
• B. Backtracking to earlier stages is possible
• C. It suits high-risk, high-stakes projects
• D. The end user is heavily involved throughout system development

8 Which of these sequences describes the order of the steps in the waterfall model?

• A. Analysis > Design > Coding> Testing > Rollout > Maintenance
• B. Analysis > Design > Coding > Rollout > Testing > Maintenance
• C. Design > Coding> Testing > Rollout > Maintenance
• D. Coding> Rollout > Maintenance & Testing

9 Identify the true statement about the spiral model of system development.

• A. It suits systems with simple requirements that can be clearly defined at the outset and then new ones can be added later
• B. It is an iterative methodology but it is also an extension of the waterfall model in how it approaches system development in a controlled manner with a defined sequence of steps in each iteration
• C. It does not respond well to significant changes occurring whilst the various iterations are underway, and this could lead to project failure
• D. It should be avoided when the client is unsure of their requirements, perhaps because they are forming a new business

10 There are 4 main stages in the spiral model of system development. What are they?

• A. (1) Identify and resolve risks; (2) Determine objectives; (3) Development; (4) Testing;
• B. (1) Determine objectives; (2) Build a prototype; (3) Evaluate the prototype; (4) Repeat 1-3 or decide it is complete;
• . (1) Determine objectives; (2) Development and testing; (3) Identify risks and resolve them; (4) Plan the next iteration;
• D. (1) Determine objectives; (2) Identify and resolve risks; (3) Development and testing; (4) Plan the next iteration;
