Assumptions: -
·
in
order to move forward, without absolute information, we need to make
assumptions. These are assumed to be true but may not be true.
·
An
assumption is a temporary decision that you make to compensate for the
information you do not have yet.
·
PMBOK describes assumptions as "factors
that, for planning purposes, are considered to be true, real, or certain."
Typical
project assumptions:-
·
Project
staff will be available as & when needed
·
Project
staff will be experienced with technical and operating environment
·
A
full time resource will at least work 35 hours a week
·
All
issues will be resolved in a timely manner
·
Statistics
used in preparing the estimates are accurate within a given %.
·
No
outside consultation will be required
·
The
scope is limited to that described in project charter
·
Formal
charter and scope change procedures will be followed.
Constraints = are the factors, that limits the
teams options such as limits on resources, budget, schedule and scope.
TRIPLE
CONSTRAINTS of PROJECT
= Cost, Schedule and Scope
Project Management Triangle/IRON
TRIANGLE (called also Triple Constraint) is a model of the
constraints of project management.
It is a graphic aid where the three attributes show on the corners of the
triangle to show opposition.
THE QUADRUPLE Constraints = Same as Triple Constraints + Quality
in Middle
¹ If any triangle is changed, then the
quality of project suffers.
