Acceptance criteria - ANS-The requirements and essential conditions that have to be achieved
before a deliverable is accepted.
Activity - ANS-(1) A task, job, operation or process consuming time and possibly other
resources.
(2) The smallest self-contained unit of work in a project.
Adoption - ANS-The optional additional phase in a linear life cycle that facilitates the use of
project outputs to enable the acceptance and use of benefits.
Agile - ANS-A family of development methodologies where requirements and solutions are
developed iteratively and incrementally throughout the life cycle.
Analogous estimating - ANS-An estimating technique based on the comparison with, and
factoring from, the cost of similar, previous work. Also known as comparative estimating.
Analytical estimating - ANS-An estimating technique that uses detailed specifications to
estimate time and cost for each product or activity. Also known as bottom-up estimating.
Assurance - ANS-The process of providing confidence to stakeholders that projects,
programmes and portfolios will achieve their objectives for beneficial change.
Baseline - ANS-The reference levels against which a project, programme or portfolio is
monitored and controlled.
Benefit - ANS-A positive and measurable impact of change.
Benefits management - ANS-The identification, definition, planning, tracking and realisation of
benefits.
Benefits realisation - ANS-The practice of ensuring that benefits are derived from outputs and
outcomes.
Bottom-up estimating - ANS-An estimating technique that uses detailed specifications to
estimate time and cost for each product or activity. Also known as analytical estimating.
Breakdown structure - ANS-A hierarchical structure by which project elements are decomposed.
Examples include: cost breakdown structure (CBS), organisational breakdown structure (OBS),
product breakdown structure (PBS), and work breakdown structure (WBS).
, Buffer - ANS-A term used in critical chain for the centralised management of schedule
contingencies.
Business case - ANS-Provides justification for undertaking a project, programme or portfolio. It
evaluates the benefit, cost and risk of alternative options and provides a rationale for the
preferred solution.
Business-as-usual - ANS-An organisation's normal day-to-day operations. Also referred to as
steady-state.
Change control - ANS-The process through which all requests to change the approved baseline
of a project, programme or portfolio are captured, evaluated and then approved, rejected or
deferred.
Change freeze - ANS-A point after which no further changes to scope will be considered.
Change management - ANS-The overarching approach taken in an organisation to move from
the current to a future desirable state using a coordinated and structured approach in
collaboration with stakeholders.
Change register (or log) - ANS-A record of all proposed changes to scope.
Change request - ANS-A request to obtain formal approval for changes to the approved
baseline
Closure - ANS-The formal end point of a project, programme or portfolio; either because
planned work has been completed or because it has been terminated early.
Communication - ANS-The process of exchanging information and confirming there is shared
understanding.
Communities of practice - ANS-are a type of learning network used within and between
organisations to maintain, develop and share knowledge.
Comparative estimating - ANS-An estimating technique based on the comparison with, and
factoring from, the cost of similar, previous work. Also known as analogous estimating.
Complexity - ANS-Relates to the degree of interaction of all the elements that make up a
project, programme or portfolio and is dependent on such factors as the level of uncertainty,
interaction between stakeholders and degree of innovation.
