  • Assuming a provider’s differentiation includes automation and API integration for self-serve iteration

    Brattle Group highlights decision-focused workflows and documents results for regulatory and market arguments, and it has limited client-facing automation and API surface versus software vendors. DNV and Wood Mackenzie prioritize engineering-led study delivery and scenario modeling workflows, so buyers seeking software-like integration should expect consulting-led delivery mechanics.

  • Allowing boundary definitions and early data availability to slip during scoping

    Guidehouse is timeline sensitive to early data availability and boundary definitions, so late data and shifting boundaries should be prevented during scoping. ICF also ties timelines to client-provided data completeness and model assumptions, so incomplete inputs should be addressed before major analysis phases.

  • Underestimating model-version drift caused by inconsistent data handoffs across workstreams

    Brattle Group requires disciplined data handoffs to avoid model-version drift because its strength centers on decision-ready documentation rather than self-serve workflow automation. Baringa requires close upfront alignment on study scope, data sources, and interfaces, so interface definitions should be part of the kickoff checklist.

  • Choosing a provider without validating how deliverables map to regulated review and stakeholder sign-off workflows

    PA Consulting emphasizes governed study delivery with study outputs aligned to utility workflows, so buyers should confirm that deliverables match stakeholder sign-off expectations. Charles River Associates delivers policy-and-market modeling synthesis as consulting team output, so procurement should ensure staffed study capacity supports the required regulatory narrative timeline.
