ERP Migration Project Manager Simulation — Siemens AG
Lead a €32M SAP S/4HANA migration for Siemens AG — one of the world's largest industrial conglomerates. Navigate divisional politics, data ownership wars, and an SI partner playing both sides as four autonomous business units are forced to standardize on a single ERP instance across 27 simulated days. Gain hands-on project management experience over 27 days of real decisions, stakeholders, and PMO deliverables — no prior experience required.
The scenario
Siemens AG — a €62B revenue industrial conglomerate with 320,000 employees — has been mandated by its CEO to consolidate four separate SAP ECC instances into a single SAP S/4HANA system with a global process template. Each of the four major divisions — Energy, Healthineers, Digital Industries, and Smart Infrastructure — has operated its own heavily customized SAP ECC environment for over 15 years, with division-specific master data models, custom ABAP programs, and localized business processes. The business driver is SAP's end of ECC maintenance in 2027. But the CEO, Roland Busch, has used this deadline to push a broader strategic agenda: 'One Siemens' — a single operating model that breaks down divisional silos. This transforms what could have been four independent technical upgrades into a politically charged organizational transformation that forces standardization across divisions that have historically operated as autonomous companies. You have been brought in as the IT Project Manager to drive delivery. Deloitte is the SI partner with a €28M contract and 18 consultants. The technical migration — brownfield conversion of four ECC instances — is well understood. The real challenge is political: four division CEOs who agreed to standardize in a board meeting but have no intention of changing their processes. Your job is to deliver a working system while navigating the most politically complex stakeholder landscape in enterprise IT.
What you'll do as the project manager
- →Consolidate four SAP ECC instances into a single S/4HANA system with a global process template and governed local variations
- →Harmonize 2.3 million master data records across four divisions into a unified data model with clear ownership and governance
- →Rationalize 847 custom ABAP programs — retire, standardize, or migrate with documented business justification
- →Achieve Wave 1 go-live (Digital Industries division) within the programme timeline with full data integrity and process functionality
- →Establish a federated governance model for ongoing process standardization and exception management across all four divisions
Project management skills you'll build
The challenges you'll navigate
- •Divisional resistance to process standardization — each BU has 15+ years of customization they consider competitive advantage
- •Data ownership disputes — no agreement on whose master data model becomes the standard
- •SI partner alignment — Deloitte has separate relationships with each BU and may be making inconsistent commitments
- •847 custom ABAP programs need disposition decisions — retire, standardize, or migrate — each one is a potential political conflict
- •Change management at scale — 80,000 users across 40+ countries need training on new standardized processes
Technology & stakeholders
You'll manage 7 stakeholders, including Hanna Hennig (Chief Information Officer), Elena Voss (PMO Director), Cedrik Neike (CEO, Digital Industries), and more.
What you'll walk away with
A verified, shareable record of a completed enterprise project — plus the PMO deliverables you produced along the way (charter, project plan, SteerCo deck, closure document). It's real, demonstrable project management experience you can put on your resume and speak to in interviews.
Frequently asked questions
Do I need project management experience to start?
No. This simulation is built for aspiring and practicing project managers alike — you learn by doing. You make real decisions and get feedback, with no PMP or prior PM job required.
How long does this simulation take?
It runs over 27 days, roughly 26 minutes per day, covering the full project lifecycle from initiation to closure.
What will I learn?
You practice the core of project management — stakeholder management, budget and schedule control, risk, scope, and PMO governance — in the context of erp migration in industrial manufacturing & technology.
Is this based on the real Siemens AG?
It's a realistic scenario inspired by Siemens AG and the Industrial Manufacturing & Technology sector. Details and names are fictionalized for training — it's a simulation, not a record of any actual project.
What do I get at the end?
A verified project completion plus the PMO deliverables you produced (charter, plan, SteerCo deck, closure) — proof of hands-on experience you can show employers.
