SOFTWARE ENGINEERING TESTGeneric products - Answers -Stand-alone systems that are marketed and sold to any
customer who wishes to buy them
•Examples•PC software such as graphics programs•Project management tools•CAD
software•Software for specific markets such as appointments systems for dentists.
Customized products - Answers -Software that is commissioned by a specific customer
to meet their own needs. •Examples -embedded control systems, air traffic control
software, traffic monitoring systems.
What is software? - Answers -Computer programs and associated documentation.
Software products may be developed for a particular customer or may be developed for
a general market.
What are the attributes of good software? - Answers -Good software should deliver the
required functionality and performance to the user and should be maintainable,
dependable and usable.
What is software engineering? - Answers -Software engineering is an engineering
discipline that is concerned with all aspects of software production.
What are the fundamental software engineering activities? - Answers -Software
specification, software development, software validation and software evolution.
What is the difference between software engineering and computer science? - Answers
-Computer science focuses on theory and fundamentals; software engineering is
concerned with the practicalities of developing and delivering useful software.
What is the difference between software engineering and system engineering? -
Answers -System engineering is concerned with all aspects of computer-based systems
development including hardware, software and process engineering. Software
engineering is part of this more general process.
What are the key challenges facing software engineering? - Answers -Coping with
increasing diversity, demands for reduced delivery times and developing trustworthy
software.
What are the costs of software engineering? - Answers -Roughly 60% of software costs
are development costs, 40% are testing costs. For custom software, evolution costs
often exceed development costs.
What are the best software engineering techniques and methods? - Answers -While all
software projects have to be professionally managed and developed, different
techniques are appropriate for different types of system. For example, games should
, always be developed using a series of prototypes whereas safety critical control
systems require a complete and analyzable specification to be developed. You can't,
therefore, say that one method is better than another.
Acceptability - Answers -Software must be acceptable to the type of users for which it is
designed. This means that it must be understandable, usable and compatible with other
systems that they use.
Stand-alone applications - Answers -These are application systems that run on a local
computer, such as a PC.
They include all necessary functionality and do not need to be connected to a network.
Interactive transaction-based applications - Answers -Applications that execute on a
remote computer and are accessed by users from their own PCs or terminals.
These include web applications such as e-commerce applications.
Embedded control systems - Answers -These are software control systems that control
and manage hardware devices.
Numerically, there are probably more embedded systems than any other type of
system.
Batch processing systems - Answers -These are business systems that are designed to
process data in large batches.
They process large numbers of individual inputs to create corresponding outputs.
Entertainment systems - Answers -These are systems that are primarily for personal
use and which are intended to entertain the user.
Systems for modelling and simulation - Answers -These are systems that are developed
by scientists and engineers to model physical processes or situations, which include
many, separate, interacting objects.
Data collection systems - Answers -These are systems that collect data from their
environment using a set of sensors and send that data to other systems for processing.
Systems of systems - Answers -These are systems that are composed of a number of
other software systems.
RE defects cost - Answers -RE defects cost 10-200 times more to
correct once fielded than they would
if they were detected during
requirements development.
Ounce of Prevention - Answers -Involve end users as early as possible.
Create a throwaway prototyping.
Deliver the software incrementally instead of all at once.
