5.7 Edit Weight Groups in the Main Work<br />

Breakdown System<br />

The main Work Breakdown System (WBS), such as the ESWBS and<br />

<strong>ShipWeight</strong> WBS, should ideally never be edited as these systems should lay<br />

firm to preserve consistency between weight groups in historical data. This is<br />

especially important when utilizing the parametric estimation in <strong>ShipWeight</strong>. It<br />

is crucial to the reliability of the parametric estimation that historical data in<br />

weight groups are comparable and on a “one-to-one” relationship in terms of<br />

definition.<br />

Still, there may be occasions when editing and/or expansion of the WBS is<br />

needed. For this, the Edit Weight Groups dialog has been made. It is opened<br />

from the <strong>ShipWeight</strong> main window menu<br />

Database->Administrator->Wgt.grp. Definition…<br />
