Ekton Project Analytics ->Learning
Discover why most Oil & Gas project teams architect their Work Breakdown Structure incorrectly from the start, systematically undermining Earned Value Management. Learn the proven framework for designing deliverable-oriented WBS structures that maintain scope integrity while enabling efficient execution flow and predictable handover.
Proper WBS structure enables effective Earned Value Management in complex Oil & Gas projects
In complex Oil & Gas projects, a properly structured Work Breakdown Structure (WBS) is the cornerstone of effective Earned Value Management. Yet most organizations make one fundamental architectural error that systematically undermines their entire project control ecosystem.
Understanding What the WBS Is Not
🚫 Not Project Phases
ENG/PROC/CONST/MC/COM are execution lenses, not scope definition
🚫 Not Disciplines
CIV/MEC/PIP/ELE represent performing lenses, not deliverable structure
🚫 Not Organizational
Contractors and budgets belong to OBS and CBS/ERP systems
🚫 Not Geographic Areas
Areas serve AWP/workface planning, not scope decomposition
Effective collaboration requires clear structural frameworks that separate scope from execution
Integrating Areas Without Corrupting Scope Integrity
Areas are vital for Advanced Work Packaging and crew flow optimization—but they must remain orthogonal to the WBS structure.
Area-Only Work
(Enabling/Physical Infrastructure)
- Earthworks & foundations
- Piperack structural steel
- Building shells & scaffolds
- Roads & civil works
Dual Foundation Work
(Area + System/Sub-system)
- Piping spools & hydrotesting
- Mechanical equipment hook-ups
- Cable pulling & terminations
- Instrument loops & commissioning
Establishing Clear Accountability Frameworks
Single Point of Responsibility
One Control Account Manager (CAM) per CA
Scope Purity Maintained
No phase or discipline contamination
Work Package Home
WPs reside within appropriate CAs
Governing Uncertainty Through Planning Packages
At FEED completion, scope uncertainty is inevitable. Planning Packages provide the mechanism to govern this uncertainty without polluting your WBS structure.
Reside within correct CA for proper ownership
Fully budgeted and time-phased against system turnover
Zero EV until conversion to executable work packages
Reason Code Framework
Architectural Comparison: Problem vs. Solution
Advanced project control rooms provide real-time visibility into WBS performance and EVM metrics
Five-Step Implementation Framework
Redraft Scope
As handover-testable deliverables
Align Boundaries
To turnover systems & sub-systems
Attribute Management
Contractors, phases, areas as attributes
Legitimate Aggregation
Higher nodes for packages & buildings
Structure Governance
Freeze baseline, manage via change control
