Describe the triple constraint. What are the three components and what is the relationship between them?
The
Triple Constraint describes
the key
attributes
every project will encounter which are Time, Cost and Scope. These
objects are usually represented as a Triangle because you can't
affect one without affecting another.
The
Time aspect of the triple constraint describes the amount of time
required to deliver the finished project. This is usually represented
as a schedule. The time restraint is also directly tied into the
scope of a project. For example, a project of higher quality will
take much longer to produce than one of lower quality.
The
Cost constraint is the amount of money needed
to complete a project, this is generally referred
to as
a budget.
The Cost is determined by various things such as resources, labor
rates or risk management etc.
Scope
tends to affect Cost directly, for instance, if a project is set to
produce something of higher quality, then
it
will cost more in turn.
Scope
itself describes
the tasks required to produce a project's end result. The quality of
the project's end result will affect the amount time required and
also the cost. Scope Creep is something that occurs when/if the scope
changes during a project's life cycle.
