Capability overview
Built around a verifiable operating model.
CutoverGrid translates technical findings into bounded engineering effort rather than a single unsupported number. The model accounts for repository and service count, dependency depth, native packages, code changes, test gaps, infrastructure work, shared foundations, coordination overhead, validation, rollout, and rollback preparation. Assumptions and exclusions stay visible alongside the range so teams know what could move it.
The same evidence is used to compare viable execution strategies. Phased migration, coordinated cutover, dual runtime, compatibility layers, canary rollout, and blue-green deployment are evaluated against dependency order, change isolation, detection latency, reversibility, team capacity, and operational constraints. The recommended approach includes its tradeoffs instead of presenting one universal pattern.
How it works
From source context to operational control.
Bound
Produce optimistic, expected, and risk-adjusted ranges from known evidence.
Compare
Evaluate migration strategies against risk, duration, reversibility, and capacity.
Calibrate
Update estimates when unknowns are resolved and compare them with actual outcomes.
Evidence produced
Every decision remains inspectable.
The capability produces structured evidence that can be reviewed by engineers and reused by downstream planning and verification.
Work drivers
Affected components, change types, dependency paths, and validation gaps.
Assumptions
Team availability, environment readiness, reuse, exclusions, and constraints.
Confidence
Evidence completeness, rule certainty, and unresolved investigation items.
Strategy tradeoffs
Exposure, coordination, rollback complexity, observation time, and cost.
Operational impact
Why this capability matters.
Leaders can make budget and sequencing decisions without pretending uncertainty has disappeared. Engineering teams receive a model they can refine by answering specific unknowns, and every estimate revision has an explainable technical cause.
