Work
Unit (WU):
A Work Unit is synonym with activity, an element of work performed
during the course of a project. A Work Unit consists of one
or several resource assignments (RAs) that have a cost estimate
or a manpower estimate and one or several deliverables (DEL).
Each WU is attached to a single Project Breakdown Structure
(PBS) code and a single Work Breakdown Structure (WBS) code.
Each WU has a label and is managed by a WU holder.
Delivrables
(DE):
Any measurable, tangible, verifiable outcome, result or item
that must be produced to complete a project or part of a project.
It is expressed in Units.

Resource
Assignment (RA):
The Resource Assignment is the resource necessary to realize
the workunit. They can refer to labour (CERN staff, Industrial
support), to overheads (duty travel, logistics,etc.) and to
material. Resource Assignments referred to F contracts or an
order in qualiac will be used in CET to forecast cash needs. |
Project
Breakdown Structure (PBS):
A structured inventory of all equipment, services and other activities
which together define the LHC project during its conceptual and
design phase. Not so useful for the time being as information has
not been consistently entered.
Work Breakdown
Structure (WBS):
A deliverable-oriented grouping of project elements that organizes
and defines the total work scope of the project.
Level of
Effort (LOE):
LOE workunits are (typically) used to spread overhead costs over
time, when no clear deliverables can be directly assigned to the
resource lines. Many
LOE workunits will thus not have deliverable lines (although they
are allowed). To define a workunit as LOE, you suffix the workunit
type with 'L' , e.g a workunit of type C would become type CL. Workunit
holders will not be asked to do "progress reporting" on LOE workunits,
since their Earned Value will be updated automatically on monthly
basis, and set equal to the Planned Value, irrespective of what
is filled in as actual quantity in the deliverable lines, if any.
LOE workunits have to be used with caution and should not represent
a high percentage of the planned value (refer to eg http://www.cpm-pmi.org/measnews/CurseEVMLOEMNJun2002.pdf
for more information).
To provide
detailed information on Workunits, or to make modifications or delete
information the 
button should be used once the relevant Workunits have been selected.
The full Workunit file will be presented in an excel file allowing
the command N (New), M (Modify) or D (Delete) to be inserted and
the necessary changes made. See annotated example below:
- New workunits:
the "N"or "n" command should be entered in
the cmd column, and the wu id should be left empty, all other
relevant columns should be filled, and each resource and deliverable
line should be preceeded with an "N"
- Modified
workunits: the "M" or "m" command should
be entered in the cmd column of all Workunit lines where data
is modified
- Deleted
workunits: the "D" or "d" command should
be entered in the cmd column of the Workunit definition line only.
All associated lines will automatically be deleted after the upload
process.
The information
will be uploaded to the database with comments that can be added.
It is important to add comments here as they appear in the activity
log and can be used to find a trace of what has been uploaded.
