Software processes - answer✔are the activities involved in producing a software system and
are abstract representations of these processes.
General process models - answer✔describe the organization of software processes.
Examples of these
general models include? - answer✔the waterfall model, incremental development, and
reusable component
configuration and integration.
Requirements engineering - answer✔is the process of developing a software specification.
Specifications - answer✔are intended to communicate the system needs of the customer to the
system developers.
Design and implementation processes - answer✔are concerned with transforming a
requirements specification
into an executable software system.
Software validation - answer✔is the process of checking that the system conforms to its
specification and
that it meets the real needs of the users of the system.
Software evolution - answer✔takes place when you change existing software systems to meet
new
requirements. Changes are continuous, and the software must evolve to remain useful.
Processes - answer✔should include activities to cope with change and may be structured for
iterative
development and delivery so that changes may be made without disrupting the system as a
whole.
ALL RIGHTS RESERVED.
Process improvement - answer✔is the process of improving existing software processes to
improve software
quality, lower development costs, or reduce development time. It is a cyclic process involving
process measurement, analysis, and change.
Agile methods - answer✔are iterative development methods that focus on reducing process
overheads and documentation and on incremental software delivery. They involve customer
representatives
directly in the development process.
agile or a plan-driven approach - answer✔The decision on whether to use an agile or a plan-
driven approach to development should depend on
the type of software being developed, the capabilities of the development team, and the
culture of the
company developing the system. In practice, a mix of agile and plan-based techniques may be
used
Agile development practices - answer✔include requirements expressed as user stories, pair
programming,
refactoring, continuous integration, and test-first development.
Scrum - answer✔is an agile method that provides a framework for organizing agile projects. It is
centred
around a set of sprints, which are fixed time periods when a system increment is developed.
Planning
is based on prioritizing a backlog of work and selecting the highest priority tasks for a sprint.
To scale agile methods - answer✔some plan-based practices have to be integrated with agile
practice.
These include up-front requirements, multiple customer representatives, more documentation,
common tooling across project teams, and the alignment of releases across teams.
Requirements for a software system - answer✔set out what the system should do and define
constraints
on its operation and implementation.
