.3 Work breakdown structure updates. In using the WBS to identify which activities
are needed, the project team may identify missing deliverables or may determine
that the deliverable descriptions need to be clarified or corrected. Any such updates
must be reflected in the WBS and related documentation such as cost estimates.
These updates are often called refinements and are most likely when the project in-
volves new or unproven technology.
6.2 ACTIVITY SEQUENCING
Activity sequencing involves identifying and documenting interactivity dependen-
cies. Activities must be sequenced accurately in order to support later development
of a realistic and achievable schedule. Sequencing can be performed with the aid of
a computer (e.g., by using project management software) or with manual tech-
niques. Manual techniques are often more effective on smaller projects and in the
early phases of larger ones when little detail is available. Manual and automated
techniques may also be used in combination.
