Four business units, one technology roadmap after the merger

After an acquisition, a retail group ran four business units on four technology stacks. NTT DATA mapped processes, applications, ERP, CRM and infrastructure across all of them and designed a low-risk transition roadmap. The group now works from a prioritized portfolio of initiatives, with synergies identified for each unit.
Business units assessed: 4
Each one reviewed across processes, applications and infrastructure.
Current-state map: Complete
One view of the group's technology and its gaps.
Transition plan: Prioritized
A post-merger initiative portfolio ordered by efficiency and risk.
Synergies: Per business unit
Optimization opportunities identified for each of the four units.
Post Merger Technology Assessment
A clear view of four technology stacks before bringing them together
Objectives
Map the technology of the four core business units and plan a structured, low-risk transition with efficiency gains after the merger.
Opportunity
A merger is the moment to simplify processes, applications and infrastructure, while the whole organization is already changing.
Four business units, four technology stacks

Each unit brought its own processes, systems and ways of working. The group needed to integrate them without putting data, security or people at risk.

Key Challenges
1: No consolidated view. Macroprocesses, applications, ERP and CRM sat in separate maps, one per business unit.
2: Data at risk. Moving to a common model put data quality and continuity on the line.
3: Security and people. The transition exposed cybersecurity gaps and asked teams to change tools and roles.
4: Synergies not identified. Nobody had listed which optimizations each business unit offered.
Solution
Assess, plan, prioritize

NTT DATA diagnosed the current technology across processes and systems and designed a transition roadmap aligned with the group’s post-merger priorities.
