Collaboration becomes commercially useful only when the project can convert shared knowledge into a baseline that leadership can challenge and govern.
The Week 9 material describes Target Cost Estimate arrangements as negotiated cost baselines developed with contractor involvement and linked to performance expectations around cost, time, quality, safety and environmental outcomes.
The material also connects target-cost thinking with alliance and incentive structures.
Week 8 already addressed incentive mechanics and shared-risk contracting. The distinct Week 9 question is how the early collaborative phase becomes a credible commercial baseline.
The Strategic Context
Early contractor involvement can improve project knowledge.
But knowledge alone does not create cost control.
At some point leadership needs to answer:
- What should this project now cost?
- What assumptions sit behind that estimate?
- Which risks remain inside it?
- Which costs are still uncertain?
- What would cause the target to change?
A target cost turns emerging design and delivery knowledge into a commercial reference point.
That reference point must be more than a negotiated number.
What Leaders Commonly Misread
The first mistake is assuming a collaboratively developed target is automatically realistic.
The second is treating transparency as evidence that costs are efficient.
The third is allowing the contractor that helped develop the estimate to become the only source of cost intelligence.
The fourth is failing to preserve independent benchmarking.
The fifth is changing the target too easily when delivery becomes difficult.
Reframing the Issue
A target cost should be understood as a governed hypothesis about the cost of delivering the agreed outcome.
It rests on:
- scope maturity;
- design assumptions;
- productivity assumptions;
- market rates;
- risk allowances;
- program;
- subcontract strategy.
The target becomes credible when those assumptions are visible and challengeable.
That is where the buyer retains commercial discipline.
Strategic Analysis
Consider a hypothetical brownfield processing-plant upgrade.
An ECI contractor has helped refine the shutdown sequence, temporary works, equipment access and installation method.
The project now knows far more than it did at concept stage.
A target cost can incorporate this information.
But leadership should still test:
- external market benchmarks;
- subcontract quotations;
- labour productivity;
- contingency logic;
- unresolved design risks.
If the target is accepted simply because it emerged collaboratively, the project may confuse cooperation with competition.
Executive Trade-offs
Target-cost development can improve price realism where uncertainty has reduced but not disappeared.
It can also reduce direct price competition.
The buyer gains visibility of cost formation.
The contractor gains early insight into the project.
Both parties may benefit from a more realistic baseline.
But the arrangement requires trust, cost transparency and strong commercial capability.
The target must remain capable of challenge without destroying the collaborative relationship.
Decision Framework
A credible target cost should pass six tests.
Scope basis
What exactly is included?
Assumptions
What design, productivity and market assumptions drive the estimate?
Risk
Which contingencies sit inside the target and why?
Evidence
What subcontract quotes, benchmarks or historical data support it?
Change control
What events can legitimately alter the target?
Performance link
How will delivery against the target influence commercial outcomes?

From Strategy to Execution
Immediate action: require a target-cost basis document, not just a total number.
Medium-term capability building: strengthen internal cost-estimating and benchmarking capability so collaborative pricing can be challenged intelligently.
Long-term strategic positioning: retain cost data from completed projects and compare target assumptions with actual performance.
This turns target costing from negotiation technique into organisational learning.
Governance Implication
Target-cost development should include a formal reconciliation between the latest design, risk register and cost model. If design maturity improves but contingency does not change, or if risks are transferred yet remain inside the target, the commercial baseline may be carrying hidden duplication.
Leadership should also define the difference between a target, a forecast and an approved budget. Treating those numbers as interchangeable weakens accountability. The target is a commercial reference point; the forecast reflects expected final cost; the budget is an organisational funding decision.
Keeping those concepts distinct improves both project controls and executive reporting.
The target should also be linked to a clear scope baseline. If scope evolves during the collaborative phase, the project needs a controlled point at which design assumptions, inclusions and exclusions are frozen sufficiently for commercial comparison.
Signals to Monitor
Watch for targets moving frequently without scope change, contingencies that cannot be explained, cost assumptions controlled entirely by the supplier, benchmarking disappearing once collaboration begins or project teams discussing the target as though it were a guaranteed final price.
Questions for the Leadership Team
- What evidence supports the target?
- Which assumptions are still uncertain?
- How was contingency determined?
- What independent challenge has been applied?
- What can legitimately change the target?
- How will actual performance against the target affect the commercial outcome?
Closing Perspective
A target cost should not be the number both parties are comfortable with.
It should be the most credible commercial baseline the available evidence can support.
Collaboration improves the data.
Governance makes the target useful.
