The Case for Dual-Track Discovery: Capability vs. Capacity
November 16, 2025

Dual-track discovery. Our view on when it adds value and how capability and capacity assessments improve supplier decisions.

What is Dual-Track discovery?

Dual-track discovery is a simple idea applied to a persistent delivery problem. It separates supplier capability from supplier capacity to give a clearer view of whether a supplier can actually deliver a package, not just win it.


It recognises that technical competence and delivery capacity are different things. A supplier can be highly capable but fully committed elsewhere. Equally, a supplier may have available resources but lack the technical maturity required for a complex or regulated scope. Treating these as one question blurs delivery viability.

The Capability Track

Capability discovery focuses on whether a supplier can deliver the work to the required standard. It looks at technical competence and the systems that support consistent delivery in regulated, high-consequence environments. This track typically examines:

  • Technical skills aligned to the package scope
  • Evidence of quality delivery on comparable projects
  • Certifications, systems, and assurance processes
  • Governance, reporting, and data maturity
  • Safety, ESG, and regulatory readiness

The objective is not to rank suppliers, but to confirm that they can meet the technical and compliance expectations of the project.

The Capacity Track

Capacity discovery focuses on whether a supplier can deliver the work within the required timeframe and at the required scale. It looks at operational reality rather than technical promise. This track examines:

  • Current workload, pipeline, and scheduling pressure
  • Workforce availability across critical roles and trades
  • Plant, equipment, and fabrication capacity
  • Subcontractor dependencies and depth
  • Financial resilience and ability to scale
  • Geographic constraints and multi-site demands

The objective is to understand whether the supplier has the bandwidth to take on the package without creating delivery bottlenecks.

Why Assessing Both Tracks Matters

Capability and capacity move independently. Assessing only one creates blind spots.

Single-track qualification often shortlists suppliers who look strong on paper but are constrained in practice. Dual-track discovery creates a more realistic fact base for shortlisting, packaging, sequencing, and mobilisation. It helps identify which suppliers are viable as-is, which require intervention, and which are simply not suited to the delivery window.

By separating these questions, organisations improve delivery confidence and strengthen commercial positioning before contracts are signed.

Our Interpretation: A Simple Rule To Follow

Dual-track discovery is not required for every procurement process. It adds value only when there is meaningful uncertainty. A simple rule applies:

  • If capability is clear and capacity is unconstrained, dual-track adds little value
  • If either dimension is uncertain, it becomes critical

In practice, dual-track discovery matters most when selecting the wrong supplier would create delays, quality issues, or resourcing constraints once delivery begins.
