Common failure modes in data science consulting engagements

Another frequent issue is treating governance as a checklist that gets appended after model build-out. Accenture and Publicis Sapient instead tie governance into production delivery automation and operational lifecycle controls, so skipping governance process alignment creates avoidable rework.

  • Expecting a consulting team to move quickly without client availability for requirements, reviews, and acceptance

    Slalom’s high-touch milestone model depends on client availability for requirements, reviews, and acceptance. Tiger Analytics similarly relies on client availability for data access, approvals, and operational cutovers.

  • Treating governance deliverables as post-build paperwork instead of production workflow controls

    Accenture embeds model governance and operational monitoring runbooks into production delivery workstreams. McKinsey & Company builds model risk management and governance inside analytics transformations tied to decision metrics.

  • Choosing a partner without a clear integration contract across teams and environments

    Accenture’s iteration speed can depend on client governance and decision cadence and it requires clear integration contracts across teams and environments. IBM Consulting also reduces friction by pairing architecture integration planning with operational handoff, which still needs clear client interfaces for delivery acceptance.

  • Assuming automation-ready interfaces will appear without alignment to existing pipelines
