Work Breakdown Structure
„
a "check list" of work to be accomplished;
a structured approach;
the scope of the work, broken down into smaller and more specialized work;
a document in which the major project work packages are identified;
a document in which the major project outputs and responsibilities are defined; and
„
an integration of schedule and budget.
„
„
„
„
allow better and more detailed planning;
„ facilitate the budget and schedule preparation process;
„ facilitate assignment of responsibility to organization
and/or functional area; and
„ provide a structure for monitoring and reporting of
project development and progress.
