The 20 questions

  1. Which must happen before a problem can be solved by a computer system?

    • The end user must test the interface before any design work takes place at all.
    • The hardware must be bought so that the size of the problem can be measured accurately.
    • The code must be written first, so that the problem can be defined afterwards from the results.
    • The problem must be defined, the system's requirements established and a data model created.

  2. How must the requirements of a system be established?

    • By choosing the fastest programming language that is available to the team.
    • By interaction with the intended users of the system.
    • By running automated tests on a finished version of the program after release.
    • By reading the source code of a similar system written in a previous year.

  3. What may the process of clarifying requirements involve?

    • Prototyping or an agile approach.
    • Writing the final program code before any users have been consulted at all.
    • Removing from the list any requirement that the users find difficult to explain clearly.
    • A single long meeting with no feedback from the users at any stage.

  4. What is a data model in the analysis stage?

    • A list of the programmers who will write the code for each data structure.
    • A description of the data the system must store and how the data items relate to each other.
    • A diagram of the hardware on which the data will be stored by the system.
    • A set of tests that checks the data entered by users when the program is run, which replaces the need for any data model at all.

  5. Why is abstraction used during analysis?

    • To make the program run faster by removing every variable from memory.
    • To model aspects of the external world in a program by keeping only the details that matter.
    • To give each program a unique name that cannot be copied by other people.
    • To hide the source code so that users are not able to read the program at all, which is the main purpose of abstraction in a program.

  6. Which is a benefit of establishing requirements with the intended users?

    • It removes the need for any testing in the implementation stage of the project.
    • It reduces the chance of building a system that does not meet the users' real needs.
    • It guarantees that the finished system will cost less than any alternative solution.
    • It means that users never need to be consulted again after the system has been delivered.

  7. What is the main purpose of the analysis stage?

    • To decide the colour scheme of the user interface for the system being built.
    • To evaluate the finished system against the original budget only at the end.
    • To write the code for the first working version of the program in the project.
    • To define the problem, establish requirements and create a data model before a solution is designed.

  8. A school wants a homework system. Which activity belongs to the analysis stage?

    • Testing the system with erroneous data to see how it reacts to bad input.
    • Interviewing teachers and students to find out what the system must do.
    • Choosing the colours and fonts that are used on the homework screen layout.
    • Writing the database query that displays homework due dates on the screen.

  9. A student is asked to analyse a shop's stock system. Which is the best first step?

    • Buy the server hardware that will store the stock records for the shop.
    • Write the stock-checking algorithm in full before any discussion with the staff.
    • Identify the users and the information they need from the system.
    • Choose the programming language that the shop's staff already know well.

  10. A prototype is shown to users for comments. Which stage does this support?

    • Evaluation, by measuring the performance of the finished system in live use.
    • Testing, by checking the final program against its specification after coding and before the program is released to the customer.
    • Implementation, by writing the code for the production version of the system.
    • Analysis, by clarifying the requirements with the people who will use the system.

  11. Which entities should a data model for a library include?

    • Program name, compiler version and total number of lines in the source code.
    • Server name, IP address and router model used in the building network.
    • Book, Member and Loan, each with the attributes it needs.
    • Screen colour, font size and button shape for each part of the interface.

  12. Which is most likely to be a requirement identified during analysis?

    • The system must record each loan with a due date.
    • The screen must be built using exactly two colours for the whole interface.
    • The code must use a recursive function for every search the system carries out.
    • The program must be compiled on one specific Linux computer in the server room.

  13. A user says the system is too slow. What does this most suggest about analysis?

    • The data model has too many entities for a small system to handle.
    • The user has been given too much training on how to use the system.
    • The program has been compiled using the wrong compiler for the platform.
    • A requirement about response time was not clearly established.

  14. Which deliverable from analysis would a designer need next?

    • A user manual written in full for the final release of the system.
    • A clear list of requirements and a data model.
    • A test report showing that every test has passed without exception.
    • A finished program with no remaining errors in any of its modules.

  15. What is an agile approach to analysis?

    • Asking only the programmers what the users need and ignoring the users themselves.
    • Writing all the requirements once at the start and never changing them afterwards.
    • Gathering requirements in short cycles with users, refining the requirements after each cycle.
    • Testing the finished program before any requirement has been gathered from anyone.

  16. Why should a data model be created during analysis?

    • So that the data the system must store is identified before the solution is designed.
    • So that the hardware can be bought before the data the system needs is known.
    • So that the user interface can be built without consulting the users at all.
    • So that testing can be skipped because the data is already assumed to be correct.

  17. Evaluate: why is the analysis stage important to a software project?

    • Errors in requirements are expensive to correct later, so an accurate understanding of the problem prevents wasted design and coding.
    • Analysis is only needed for very small projects, because large projects are always designed first.
    • Analysis replaces testing, because the requirements are assumed to be correct from the start.
    • Analysis is carried out after evaluation, so it does not influence the design of the system.

  18. A team builds a prototype, but users keep changing their minds. What is the best response?

    • Ignore the users and build the system to the first set of requirements only.
    • Refuse all further changes so that the project is finished on time and on budget.
    • Accept iterative change, refining the requirements and the prototype with the users in further cycles.
    • Stop the analysis and start implementation so that the users see working code sooner.

  19. Which statement best describes the link between analysis and the data model?

    • The data model replaces the requirements, so the requirements are no longer needed.
    • The data model is a list of user interface controls rather than a description of data.
    • The data model is created after implementation and is used only for testing the program.
    • The data model captures the entities and relationships identified during analysis.

  20. A system must serve users with different needs. What is the best analytical approach?

    • Identify the different user groups and their requirements, then model the data and functions each group needs.
    • Choose one user group arbitrarily and ignore all the others in the design of the system.
    • Merge all users into one generic user with no particular needs or preferences at all.
    • Build the system for the most powerful computer and let the users adapt to it.
