Cutover management

A go-live without surprises

Cutover is the most critical moment of an ERP transformation. We plan and run it hour by hour, with rehearsals and a clear go/no-go, so daily operations keep running.

Why go-lives go wrong

Most cutover problems are planning problems.

1

No realistic plan

The cutover plan is a list of tasks without timings, owners or dependencies.

2

No rehearsal

The first time the steps are run end to end is during go-live itself.

3

No clear go/no-go

Nobody has agreed in advance what 'ready' means, so the decision becomes political.

What we take on

On SAP and Microsoft Dynamics programmes, greenfield or brownfield, on-site or remote.

  • Cutover strategy and hour-by-hour runbook
  • Dress rehearsals and timing validation
  • Go/no-go criteria agreed upfront
  • Business continuity and fallback scenarios
  • Command centre during go-live
  • Hypercare and aftercare

A typical cutover timeline

  1. Months beforeStrategy

    Cutover approach, downtime window and business continuity.

  2. Weeks beforeRunbook & rehearsals

    Hour-by-hour plan, proven in dress rehearsals.

  3. Days beforeGo/no-go

    Criteria checked against facts from testing and data.

  4. After go-liveHypercare

    Intensive support until operations are stable.

Not a system integrator. On your side of the table.

We represent your business during the transformation. We combine business and technical knowledge, so we can challenge your integrator on what is actually necessary.

A system integrator

  • Paid to deliver the system they sell
  • Scope and change requests drive their revenue
  • Technical view of your processes
  • Leaves after go-live

Optinus

  • Paid to deliver the outcome your business needs
  • Challenges every deviation and change request
  • Combines business and technical knowledge
  • Stays through hypercare and aftercare

How we work

Go-live as a rehearsed, controlled event.

  1. Plan

    An hour-by-hour runbook with owners, timings and dependencies.

  2. Rehearse

    Dress rehearsals until the timings are proven.

  3. Decide

    Go/no-go criteria agreed upfront, so the decision is based on facts.

  4. Go live

    Command centre during cutover, then hypercare and aftercare.

How we can work together

Three ways to engage, depending on where your programme stands.

Option 1

Interim leadership

An Optinus programme, project or workstream manager joins your organisation for the duration of the programme.

Best for: Programmes that need senior leadership on the business side.

Option 2

Workstream delivery

We take ownership of a defined workstream, such as data migration, testing or cutover, with clear deliverables.

Best for: Specialist workstreams that need full focus.

Option 3

Assessment

A short, fixed-scope review of your programme or your readiness, with clear findings and recommendations.

Best for: An independent view before you make the next decision.

Designing and leading the HORIZON transformation

Nature's Pride outgrew Navision. Optinus designed and leads the HORIZON programme in five phases, with a 360-degree view on people, process, data and technology: standardise first, flexible only where Nature's Pride is unique.

  • Phased waves instead of a big bang

Frequently asked questions

When should cutover planning start?

Months before go-live. A good cutover plan shapes the data migration and test plans, not the other way around.

What does 'independent cutover lead' mean?

We run the cutover on behalf of your business, so the go/no-go is based on facts and not on the integrator's schedule. That is exactly the role we played at Saint-Gobain.

Do you stay after go-live?

Yes. Hypercare and aftercare are part of our approach.
