The owner's challenge
As a project develops, the owner learns more about operating requirements, technical options and the market the facility will serve. A proposed owner scope change may improve the business outcome. It can also affect work already committed or create consequences outside the part of the project where it originated.
A quoted equipment price may describe only part of the commitment. The change can affect related engineering, installation, controls, operating preparation or the timing of other work. Several individually reasonable changes can also alter the overall investment proposition.
Sand Hill perspective
We treat an owner scope change as a decision about value. The relevant comparison is the benefit the change is expected to create and the full set of consequences the owner would accept. Those consequences need to be understood while the choice can still be made.
This also preserves the meaning of project performance. When approved scope changes are visible, the owner can distinguish the cost of a deliberate investment choice from variation in delivering the agreed scope. A clear comparison helps leadership understand what was purchased, what was delivered and why the financial position changed.
Owner scope, cost trends and contractor changes
Owner changes relate to the intended project scope established during baselining. Changes in expected cost and contractor changes require their own evaluation.
| Concept | Basis for evaluation | Management focus |
|---|---|---|
| Owner scope change | A change to the intended project scope established during baselining. | Understand the revised benefit and its implications for cost, schedule, risk and delivery. |
| Cost trend | Emerging cost information that may reveal market conditions, systematic estimating weaknesses or an incomplete understanding of the market. | Investigate the cause and its implications for future purchases and the forecast to complete. |
| Contractor change | A change or request arising within a contractor's scope, execution or commercial arrangements. | Evaluate the specific issue and establish whether it relates to an owner scope change, a cost trend, both or neither. |
These concepts can overlap. An owner-requested capacity increase may generate a contractor change. A contractor's pricing proposal may reveal a broader cost trend while the owner's intended scope remains unchanged.
The relationships should be understood, while each issue remains distinctly controlled. This preserves a meaningful view of owner decisions, emerging cost exposure and execution performance. Recognizing exposure in a forecast does not, by itself, approve a change or establish entitlement to payment.
Implications for owners
- Consider the whole effect of the proposal. Changes to one part of a facility can influence other work and the intended operating result. The commercial decision should reflect those relationships alongside the immediate purchase cost.
- Bring the decision forward while alternatives remain practical. Once related work or commitments have advanced, the same change may have a different cost, timing or set of consequences for the owner.
- Keep approved decisions visible in the investment record. Leadership needs a consistent account of how the scope and expected benefit evolved, including the cumulative effect of changes accepted over time.
- Keep owner scope changes, cost trends and contractor changes distinct. Investigate their relationships without allowing one classification to stand in for another.
A disciplined owner scope decision connects the proposed benefit to the commitment it requires. Keeping owner scope changes, cost trends and contractor changes distinct preserves a meaningful view of cost, schedule and delivery performance.
