The worksheet for
example is shown below after the data has been entered. The
project is described by the Work Breakdown Structure or
WBS. The principle characteristic of the WBS is that it includes
all activities that must be performed to complete the project
and that the activities not overlap in function. There are
many uses for the WBS including assigning of management responsibilities
and the time scheduling of activities as described in our Project
Management add-in. Here we use it for estimating the
costs associated with the project. This is called the Capital
Activities are described
by integer indices. Level 1 is for the project and is assigned
the number 1. This number is the same for all activities on
the worksheet, so we do not provide a column for this index.
Column C shows the index for the first level of detail. It
is labeled L2 because it is the second index for the activities.
Activities are uniquely identified by the indices. For example
is written as "1.2 Capacity Planning". The program
makes no attempt to sort the activities by number or assure
that activities have unique numbers. This is the responsibility
of the user.
For our example we use 1.0 for the project and use the last
activity for the completion, or Finish, event. The Change button
at the top of the form is used to add or delete rows from the
structure. Rows cannot be added before the first row or after
the last one. The first and last rows cannot be deleted.
