Choosing a provider that is misaligned to the dispute or enforcement endpoint
Selecting The Prosecution Support Unit Network for internal audit or standalone tooling needs can misalign outputs because its work is built for prosecution workflows and court-ready case support. Choosing The Brattle Group without a damages-driven litigation objective can also overinvest in economic expert modeling that is most effective for complex disputes.
Underestimating evidence access and documentation workflow dependencies
Grant Thornton and BDO both require strong client data readiness because investigation timelines depend heavily on access to records and evidence quality. Kroll and FTI Consulting also rely on client data readiness for case management to avoid delays.
Assuming the right analytical method alone solves admissibility and usability needs

Kroll and FTI Consulting can feel heavy for small, time-limited fact-finding because complex fraud and dispute-ready documentation adds process depth.
