Tanker deck at night under a clear starfield

Key takeaways

  • Separate the number of candidates from the value of the alternatives they offer.
  • Include the consequences of changing the cargo programme to access more ships.
  • Compare confirmed opportunities with conditional ones transparently.
  • Use a threshold to identify how much improvement would justify the change under the stated model.

The worked case below is an original fictional procurement exercise. It contains no current vessel availability, freight quotations or actual delay costs. The model illustrates a decision trade-off rather than predicting how a market will respond to a different supply picture.

Start with the opportunity set the desk can use

A supply note may identify more ships in a later period or another area. The commercial question is whether those candidates create feasible alternatives for this cargo. The desk needs to know what would change in the programme and whether the relevant parties can support that change.

A candidate is not automatically an offer. Preserve the distinction between a confirmed commercial proposal, a potential opening and a speculative lead. A larger set of leads may justify more enquiry without establishing that the desk can obtain better terms.

Also examine whether the candidates are genuinely different alternatives. Duplicate reports, incompatible windows or unresolved suitability can inflate the apparent choice. The value of the set depends on what can actually compete for the defined employment.

The analysis should therefore connect supply evidence to a specific decision, such as retaining the current programme or testing an alternative window. A broad statement that supply is improving leaves the cost of that choice unanswered.

Identify the cost of accessing additional supply

Changing a cargo window can affect costs outside the freight invoice. The relevant consequences depend on the actual programme and may involve storage, receiving arrangements or other commercial commitments. Include only effects supported by the specific analysis.

Do not add every conceivable disadvantage to the alternative. Determine which amounts genuinely change and which remain the same under both options. Where a cost is uncertain, show its status and test its effect rather than presenting it as a confirmed charge.

The timing change may also affect feasibility. A lower modelled cost is not useful if the receiver cannot accept the revised programme or the cargo cannot remain available. Keep feasibility constraints separate from the financial ranking so the model does not appear to solve them.

Illustrative choice: more later candidates, higher total cost

ILLUSTRATIVE — invented cargo, prices and programme costs, not live offers. A fictional desk models a 40,000-tonne cargo. The current-window option uses an assumed freight rate of USD 20 per tonne, giving USD 800,000 of freight.

A later-window scenario assumes USD 19 per tonne, giving USD 760,000 of freight. Accessing that later scenario requires a 4-day programme shift, with an invented incremental cost of USD 14,000 per day. The model therefore adds USD 56,000 to the later option.

Fictional optionFreight rateFreight amountIncremental programme costDefined comparison total
Current windowUSD 20/tUSD 800,000USD 0USD 800,000
Later windowUSD 19/tUSD 760,000USD 56,000USD 816,000

The later freight assumption is USD 40,000 lower, but its defined total is USD 16,000 higher. A larger possible candidate set would not, by itself, make the later option preferable under these inputs.

The later freight amount would need to be no more than USD 744,000 to match the current total: USD 800,000 − USD 56,000. Dividing by 40,000 tonnes gives a threshold of USD 18.60 per tonne.

If the later freight assumption were USD 18.50 per tonne, freight would be USD 740,000 and the defined total USD 796,000, a saving of USD 4,000. That narrow difference remains conditional on the invented programme cost and every other model boundary.

Read the threshold as an enquiry target, not a prediction

The threshold tells the desk what the alternative must achieve within the model. It does not establish that the market will provide that price or that a suitable ship will be available on those terms.

The next task is to test the actual commercial opportunity and the programme-cost assumption. If either is unresolved, the model should remain a conditional comparison. A forecast of more candidates is not a substitute for an offer.

The threshold also helps assess materiality. If a small change in the programme cost reverses the result, the desk should not present the ranking as robust. Investigate the uncertain input or explain the limited margin between alternatives.

Do not turn the threshold into an instruction to delay automatically. The physical programme, commercial authority and actual terms remain necessary parts of the decision. The calculation narrows the question; it does not answer every part of it.

Distinguish bargaining context from an executable alternative

Evidence of a wider candidate set can be useful in commercial discussion even before a preferred alternative is confirmed. It may justify testing more counterparties or asking whether a proposal can be improved. That value is different from having a completed replacement option.

Be precise in the recommendation. “Seek additional comparable proposals” is supportable when the evidence suggests more possible candidates. “Switch to the later window” requires the additional feasibility and commercial work that makes the alternative concrete.

Avoid overstating the effect of supply on price. A candidate set interacts with other employment choices and the actual terms sought. The desk should use verified responses to assess what the additional choice is worth for this enquiry.

Test the quality of the alternative set

Use the following original checklist before relying on a supply argument in a procurement decision.

  1. Confirm that the additional candidates meet the same defined cargo and service requirements.
  2. Reconcile their opening periods with the actual alternative programme.
  3. Separate confirmed proposals from conditional candidates and unverified leads.
  4. Identify the programme changes needed to access them and the resulting costs.
  5. Test whether the alternative remains worthwhile under reasonable changes to unresolved assumptions.

The checklist should produce a more focused enquiry, not a ceremonial count of completed fields. If the decisive issue is receiving flexibility, resolve that issue rather than expanding the vessel list indefinitely.

Explain the final choice in terms of trade-offs

A defensible recommendation states why the preferred option serves the programme better under the evidence available. It may favour the current window despite a wider later candidate set, or favour the alternative after actual terms and programme costs support it.

Preserve the condition that could change the choice. A revised offer, a different programme cost or newly confirmed flexibility may justify another comparison. The desk should be able to update that specific assumption without rebuilding the whole market story.

The final statement should remain within the model's scope. A defined cost comparison is not a complete assessment of every contractual or operational consequence. Make the material remaining questions visible to the responsible decision-maker.

Common mistakes

Treating more names as better value. Assess viable commercial alternatives and the cost of accessing them.

Comparing freight alone after changing the programme. Include relevant incremental consequences of the changed window or arrangement.

Presenting a threshold as an available rate. It is a model result that must be tested against actual commercial evidence.

Ignoring a narrow decision margin. Identify uncertain inputs that could reverse a small apparent advantage.

Frequently asked questions

Does a larger candidate set always improve the decision?

It may expand enquiry opportunities, but the alternatives must be feasible and commercially worthwhile for the actual programme.

Why include programme costs in a supply comparison?

The desk may need to change timing or arrangements to access the additional candidates. Those incremental consequences affect the value of the choice.

What does the calculated threshold establish?

It identifies the freight level needed to match the current option under the model's assumptions. It does not establish an executable offer.

Can conditional candidates still be useful?

Yes, as leads for further enquiry or scenario analysis. Keep their status distinct from confirmed commercial alternatives.

What should change the recommendation?

New evidence affecting feasibility, actual terms or a material cost assumption. State the relevant trigger so the decision can be reassessed coherently.
