Executive Roadmap and Investment Governance

A quantum program can consume indefinite money if every milestone is framed as “research progress.” Executive governance converts curiosity into staged investment.

The purpose is not to make quantum conservative. The purpose is to fund uncertainty deliberately.

50.1 Investment thesis

    Thesis[Investment thesis] --> Option[Strategic option value]
    Thesis --> Capability[Internal capability]
    Thesis --> UseCase[Use-case discovery]
    Thesis --> Risk[Quantum risk reduction]
    Thesis --> Product[Future product platform]

Executives should state which thesis they are funding. A program designed for post-quantum cryptography migration is different from one designed for chemistry research, vendor evaluation, cloud platform development, or fault-tolerant service readiness.

50.2 Stage gates

    Productize --> Scale[Scale]

Qiskit Serverless, Braket reservations, and Azure Quantum jobs are examples of cloud-era execution and orchestration primitives. Executive roadmaps should evaluate how such primitives reduce internal build burden while preserving evidence, governance, and portability. [R76] [R77] [R78]

50.3 Portfolio model

A mature quantum portfolio has multiple lanes.

    Portfolio[Quantum portfolio] --> Risk[PQC and security risk]
    Portfolio --> Research[Scientific research]
    Portfolio --> Platform[Platform capability]
    Portfolio --> Vendor[Vendor evaluation]
    Portfolio --> Product[Product opportunities]
    Portfolio --> Talent[Workforce development]

Do not mix these lanes into a single ROI claim. Some lanes are defensive, some are exploratory, some are infrastructure, and some may become products.

50.4 Kill criteria

A program without kill criteria will continue because it exists.

investment_gate:
  stage: prototype | validate | productize | scale
  continuation_criteria:
    - evidence threshold
    - cost threshold
    - capability threshold
  kill_criteria:
    - baseline not beaten after defined attempts
    - cost exceeds option value
    - vendor dependency unacceptable
    - platform risk unmanaged
  pivot_options:
    - change use case
    - change vendor
    - simulate instead of execute
    - convert to training program

flowchart LR
    Gate[Investment gate] --> Continue{Criteria met?}
    Continue -- yes --> Fund[Continue funding]
    Continue -- partially --> Pivot[Pivot]
    Continue -- no --> Stop[Stop or archive]
    Pivot --> NewGate[New gate]

Stopping a workload is not failure. Continuing a workload with no evidence is failure.

50.5 Executive dashboard

    Dashboard[Executive dashboard] --> Capability[Capability maturity]
    Dashboard --> Evidence[Evidence quality]
    Dashboard --> Cost[Cost and capacity]
    Dashboard --> Risk[Security and compliance risk]
    Dashboard --> Vendor[Vendor dependence]
    Dashboard --> Talent[Talent readiness]

The dashboard should avoid vanity metrics.

50.6 Fault-tolerant readiness

Fault-tolerant readiness is not waiting for a magic machine. It is preparing the organization to use logical services when they become real.

flowchart LR
    Today[NISQ and early utility] --> Logical[Logical-qubit experiments]
    Logical --> Services[Fault-tolerant service candidates]
    Services --> Products[Qualified quantum products]

Google’s below-threshold and dynamic-surface-code work shows that the field is making concrete progress on error-correction operations, but a business roadmap still needs gates: logical error rate, decoder latency, logical operation set, resource estimates, service availability, cost per useful result, and application-level advantage. [R90]

50.7 Board-level questions

Executives and boards should ask:

1. What decisions has the quantum program improved?
2. What risks has it reduced?
3. Which workloads have evidence packages?
4. Which claims are we willing to make externally?
5. Which vendors are strategically important and why?
6. What is our PQC migration status?
7. What would cause us to reduce, redirect, or increase investment?
8. What capability do competitors or partners have that we lack?

50.8 Closing principle

The quantum program should produce three assets:

• evidence,
• capability,
• optionality.

If it produces only excitement, it is under-governed. If it produces only papers, it is under-integrated. If it produces only infrastructure, it is under-directed. The operating discipline of the book is designed to keep all three assets in view.
