Another recurring failure mode is misalignment on integration contracts and release mechanics across teams. Thoughtworks and Globant require client collaboration to sustain domain and delivery alignment or to support stable API contract outcomes, while Deloitte and EPAM Systems add coordination overhead that can derail short-scoped work.

  • Treating contract governance as optional when integration risk is the main risk driver

    Infosys bases integration work on documented API contracts, and skipping that mapping slows architecture and release alignment. Globant coordinates API contract alignment across engineering, QA, and integration workstreams, which fails when contract owners are not available.

  • Overloading lightweight change requests into governance-heavy release checkpoint models

    Tech Mahindra’s admin tooling for business users can feel heavier than lightweight configuration, which increases friction for small scopes. Deloitte’s governance-led delivery can slow decisions on small or short scopes when stakeholder decisions lag.

  • Understaffing contract and architecture decision roles during modernization cycles

    HCLTech’s interface contracts depend on active stakeholder availability for integration decisions, and limited availability increases cycle time. Thoughtworks requires close client collaboration to sustain domain and delivery alignment across increments.

  • Assuming release governance is the same as release execution across environments

    Tech Mahindra pairs API-centered integration with release traceability across environments, which requires a real promotion and evidence workflow. EPAM Systems provides structured release governance and release operations, which creates coordination overhead if governance artifacts are not adopted by the client.

  • Delaying required governance collaboration for security and audit planning in integrated landscapes

    Luxoft notes that governance artifacts like detailed RBAC and audit log plans can require vendor collaboration. Without early alignment on those plans, security governance work can block modernization delivery schedules.
