    The Problem

    75% of ERP implementations fail to meet objectives. Only 8% of S/4HANA migrations complete on schedule. The common thread: the people running the legacy system are the same people expected to build the new one. Not because leadership didn't care. Because nobody designed an operating model where both workstreams could succeed at the same time.

    The Six-Stage Lifecycle

    The playbook maps the complete JDE transition — from organizations that aren't migrating yet to those already in post-go-live stabilization.

    Optimize & Sustain

    For JDE shops not migrating. Stabilize the environment, automate repetitive work, reduce TCO. This is where most organizations should start — whether or not a migration is on the horizon.

    1
    Selection Advisory

    Platform-neutral evaluation of Fusion, NetSuite, S/4HANA — or staying on JDE. Allari has no vendor affiliate relationships. The advisory output is yours to keep.

    2
    Pre-Migration Health Check

    Forensic capacity measurement before committing to an SI timeline. The 38.4% reactive load doesn't appear in vendor assumptions. This stage surfaces it.

    3
    JDE Operations During Migration

    Full operational custody of JDE so the core team can focus entirely on the build. The Operational Airlock: one team owns production, one team owns the future.

    4
    Client-Side SI Oversight

    Governance layer between the client and the SI. Your eyes inside the build process — making sure the configuration decisions reflect your operational reality.

    5
    Post-Go-Live Stabilization

    Hypercare and knowledge transfer on the new platform. The transition isn't complete at go-live — it's complete when the team owns the system.
