From 140 Legacy Apps to One Unified Platform
How Maintain Technology Drove Functional Transformation and Platform Consolidation Across a Complex Enterprise
Industry
Public Sector / Asset-Intensive Enterprise
Engagement
Functional Transformation & Platform Consolidation
Outcome
140 legacy applications retired, one unified platform deployed, and functional processes streamlined enterprise-wide.
Case Study
The client was operating on a fragmented technology landscape, with 140 legacy applications—many custom-built—featuring overlapping functionality and siloed data. This led to high operating costs due to licence duplication, infrastructure sprawl, and vendor complexity, as well as inconsistent business processes across departments that slowed decision-making and increased compliance risks.

The Challenge
The client was operating on a fragmented technology landscape, with 140 legacy applications—many custom-built—featuring overlapping functionality and siloed data. This led to high operating costs due to licence duplication, infrastructure sprawl, and vendor complexity, as well as inconsistent business processes across departments that slowed decision-making and increased compliance risks. Previous attempts to rationalise the environment had stalled because of conflicting stakeholder priorities, the absence of a clear migration pathway, and concerns over operational disruption during consolidation.
Our Approach:
The Maintain Technology Transformation & Consolidation Framework
We deployed a four-stage enterprise transformation method:
Stage 1
Rapid Assessment & Application Mapping
Inventoried all 140 applications, documenting ownership, usage, dependencies, and business criticality. Mapped functional overlaps and identified candidates for consolidation or retirement.
Stage 2
Future-State Process Design
Engaged functional leads to design standardised, best-practice processes. Defined target capabilities to be delivered on the unified platform.
Stage 3
Platform Selection & Migration Roadmap
Facilitated vendor-neutral platform evaluation. Developed a phased migration plan balancing quick wins with high-value transformations.
Stage 4
Change Enablement & Execution
Coordinated cross-functional teams to execute migrations with minimal disruption. Delivered targeted training and adoption support to embed the new platform.
Result
- 134 legacy applications retired — reducing licensing, hosting, and support costs by millions annually.
- One unified platform deployed, improving cross-department data sharing and reporting accuracy.
- Business processes standardised, reducing cycle times and enhancing compliance.
- Stakeholder alignment achieved, enabling faster decision-making and future transformation readiness.
Why It Matters
Application sprawl silently drains budgets and slows business. Maintain Technology’s structured, business-led approach ensures that consolidation isn’t just a technical exercise — it’s a functional transformation that unlocks efficiency, agility, and long-term value.

How Maintain Technology Helped Restore Delivery Confidence by Making Critical Decisions Before More Value Was Lost
Case Study
In a live ERP environment, three key decisions made within a few hours prevented $500k in unnecessary cost. The real issue was not the saving itself. It was that the cost should never have existed in the first place. Delivery had started to drift, accountability was diffused, and unresolved decisions were becoming expensive.

How Maintain Technology Reduced Defects and Increased Go-Live Confidence Through Structured Testing Assurance
Case Study
The client’s projects were plagued by poor quality assurance processes that resulted in high defect counts in production, stressful go-lives requiring emergency fixes, and extended post-implementation support. With no consistent testing methodology in place, quality standards varied widely between vendors and teams.
