Context & Challenge
SUSE underwent a complex carve-out and subsequent merger, involving multiple vendors and a large, inherited IT landscape:
- ~400 applications across business domains and geographies
- On-premises systems that needed to move to AWS and secure internal environments
- Parallel initiatives to implement S4HANA Cloud, Salesforce, Marketo and other strategic platforms
- A fragmented collaboration landscape (Slack, Microsoft Teams, Rocket.Chat, IRC, multiple email flavours)
The challenge was to separate, simplify and modernise the IT landscape while keeping the business running and aligning with the new ownership structure.
Approach
1. Portfolio & Architecture Governance
Led the overall enterprise architecture workstream within a multi-million Euro programme. Collaborated with Accenture and internal stakeholders across all departments. Established architecture principles and governance processes to review all major designs.
2. Portfolio Rationalisation
Analysed the full application portfolio (~400 apps). Identified redundancies, legacy systems and opportunities for consolidation. Designed a roadmap to reduce the portfolio to around 80 key applications, aligned with business capabilities.
3. Cloud & SaaS Migration
Reviewed and guided target architectures on AWS and secure on-prem systems. Oversaw migration to S4HANA Cloud (SAP) as the core finance platform, Salesforce for CRM, and Marketo for marketing automation.
4. Collaboration & Identity
Scoped and helped implement a unified digital collaboration platform to replace Slack, Rocket.Chat, IRC and multiple Teams setups. Oversaw design for Enterprise Identity Management involving AWS IAM, Okta and Azure AD.
5. Organisation & Operating Model
Designed the new IT organisation and operating model, including required roles, skills and governance. Supported hiring and vendor coordination across multiple teams and countries.
How this maps to my services
This case shows the upper end of what I do in M&A, Carve-out & IT Rationalisation engagements, AI-Ready Cloud & Data Foundation (adapted to large software vendors), and public sector / consortium-style programmes where governance and multi-vendor coordination are critical.
