软件工程复习题-问答题
QA
1. What are the essential attributes of good software?
Maintainability, dependability and security, efficiency and acceptability
2. What is software engineering?
An engineering discipline concerned with all aspects of software production from specification to system maintenance.
3. What are the four fundamental activities in software processes?
Software specification, software development, software validation and software evolution.
4. What software engineering fundamentals apply to all types of software systems?
a. Systems should be developed using a managed and understood
development process.
b. Dependability and performance are key system characteristics
c. Understanding and managing the software specification and requirements are important.
d. Effective use should be made of available resources.
5. List the 3 generic process models that are used in software engineering? The waterfall model
Incremental development
Reuse-oriented software engineering
6.What are the three benefits of incremental development, compared to the waterfall model?
(a) The cost of accommodating changes to customer requirements is reduced. (b) It is easier to get customer feedback on development work that has been done.
(c) More rapid delivery and deployment of useful software to the customer is possible.
7.What are the principal requirements engineering activities?
Feasibility study
Requirements elicitation and analysis Requirements specification
Requirements validation
8.What are three important characteristics of extreme programming? Requirements expressed as scenarios,
Pair programming,
Test-first development.
9. What is the distinction between functional and non-functional requirements? Functional requirements define what the system should do. Non-functional requirements are not directly concerned with specific system functions but specify required system properties or place constraints on the system or its development process.

10. What is the software requirements document?
The official document that defines the requirements that should be
implemented by the system developers.
11. What is a use-case?
A use-case identifies a typical interaction with a system and the actors (human or computer) involved in that interaction.
12. What is requirements management?
The process of managing changes to requirements during requirements specification and after the system has gone into use.
13. What are the 5 key activities in an object-oriented design process?
Understand and define the context and use of the system. Design the system architecture
Identify the principal objects in the system
Develop design models
Specify object interfaces
14. What are the principal aims of software configuration management? To support system integration so that all developers can access the project code and documents in a controlled way, find out what components have been changed and compile and link components to create a system.
15. What is the distinction between validation and verification?
Validation: Are we building the right product?
Verification: Are we building the product right?
16. What are the advantages of inspections over testing?
Inspections can discover many errors. In testing, one error may mask another. Incomplete versions of a system can be inspected.
Inspections can consider broader quality attributes as well as program defects.
17. What is an equivalence partition?
A class of inputs or outputs where it is reasonable to expect that the system will behave the same way for all members of the class.
18. What are the three types of user testing?
Alpha testing, where users work with the development team to test the software as it is being developed.
Beta testing where the software is released to selected users for testing before the formal system release
Acceptance testing, where customers test a system to check that it is ready for deployment.
19. What are the three different types of software maintenance and how is effort distributed across these maintenance types?
Maintenance to repair software faults (17%),
Maintenance to adapt the software to a different environment (18%), Maintenance to add to or modify the system s functionality (65%).

Reverse engineering,
Program structure improvement,
Program modularization
Data re-engineering
21. List four important factors used to assess applications for maintenance. Any four from:
Understandability, Documentation, Data, Performance, Programming language, Configuration management, Test data, Personnel skills
