In Adeaca PBA, the Work Breakdown Structure (WBS) is used for planning and executing the project operationally. A separate but linked hierarchy, the Cost Breakdown Structure (CBS), is used for financial planning and execution. You can think of the WBS as the project planner’s structure and of the CBS as the project controller’s structure.
Typically, the CBS is less granular than the WBS. For instance, the WBS for a single project may hold 500 tasks to manage the operational deliverables, but the same project only has 50 CBS accounts to financially plan and control the engagement.
Maintaining budgets, actuals, commitments, estimates and variances at WBS task level is, for most companies, impractical leading to data entry errors and inflated administration without any added benefits.
WBS tasks can optionally be linked to CBS accounts. This linkage allows you to transfer time-phased estimates, remaining work and more from the WBS to the CBS. Additionally, a CBS account can be identified either by the CBS account code or by the linked WBS task code. This means that users unfamiliar with the CBS can identify proper CBS accounts via WBS tasks.
Working with dedicated financial and operational structures allow companies to define each for optimal operational and financial efficiency and control.
