what is the bathtub curve and what does it show? - answer✔It is a graph of failure rate versus
time and shows a very high, short lived period of initial failures (infant mortality), a flat low
failure rate, long period (useful life) then steadily rising failure rate (wear out/obsolescence
Upgrades create their own "blip" followed by a slightly higher failure rate.
What is a stakeholder - answer✔the person/ people or organisation that has the rights, shares,
or say in the software that is being produced

Application software - answer✔stand alone programs which uses algorithms to solve a specific
business need by processing business or technical data. ____________ is produced for the end
user and can include various interactive applications, computer aided design etc.
_____________ have started to display similar characteristics to real time and system software
ALL RIGHTS RESERVED.
Embedded software - answer✔usually has processing and memory limitations, but can range
from simple systems such as dishwashers and remote controllers to more complicated systems
such as operating a vehicle (braking, steering, dashboard).
Modern embedded software is typically stored in flash RAM
Product line software - answer✔designed to operate on many computers and serve a wide
range of users. Ranging from word processing, spreadsheets, computer graphics and
entertainment to database management and inventory control products.
ie. mass consumer market software to more specialised software.
Bespoke software - answer✔custom made software that meets a specific customers

solving
Weighs up alternatives to find best solution
within this field are subjects such as robotics, game playing and artificial neural networks.
Legacy software
Why do businesses use it? - answer✔old or obsolete software that is critical to business
operations and longevity.
__________________ may still be used because it is able to run reliably and operate according
to user specifications, but is often categorized as poor quality (it may have insufficient
documentation, messy code, be inextensible etc.)
over time ___________ may need to be updated or replaced in order to evolve. This allows re-
engineering the software so that it can interoperate and cooperate with modern software
systems
Mongolian horde myth - answer✔based on the idea that throwing extra resources at a problem
will mean that it can be solved quicker. In software engineering
Programmers that are added to project often require extensive training, which draws focus
away from the project itself
pre planning is highly recommended in order to successfully integrate new people into a team
software project tracking and control - answer✔lets the software team compare their current
progress with the projects plan in order to asses whether or not the project is developing as
expected.
software technical reviews - answer✔peer reviews that asses the quality of the product. This is
an effective way of identifying and removing errors that could extend into other areas of the
project
Re usability management - answer✔emphaiszes the development of software that can be re-
used. This involves putting specific criteria in place that allows software (and software
components) to be re-usable
What is software
3 ways its used - answer✔The vehicle used to deliver the product.
Software acts as the basis for the control of the computer (operating systems),
the communication of information (networks) and
