BREAK THE LEGACY-TO-DIGITAL BARRIER

​

THE LEGACY EVOLUTION CHALLENGE

While many organizations focus on the visible symptoms of legacy challenges – rising maintenance costs, slow innovation cycles, and growing security concerns – the real issue runs deeper.

The problem isn’t just aging technology; it’s the mindset that legacy systems must be completely replaced to drive value.

This thinking leads to:

• Massive replacement projects that fail to deliver
• Rising technical debt as teams avoid touching “old” systems
• Innovation paralysis from fear of breaking critical functionality
• Growing maintenance costs with diminishing returns
• Competitive disadvantage as more agile players enter the market

​

THREE HORIZON MODERNIZATION MODEL

Legacy transformation succeeds when you balance immediate stability with long-term innovation. Plan and deliver using three horizons, each achieving and delivering a more scalable and robust capability.

​

1. Stabilize (Horizon 1). First, get everything working as close to flawlessly as feasible.
   • Use a Risk Assessment Framework to:
     • Identify critical vulnerabilities
     • Map dependency chains
     • Quantify business impact
   • Optimize for quick wins. Prioritize:
     • Performance improvements
     • Cost reduction opportunities
     • Security enhancements
   • Dial in Operational Excellence. Include:
     • Implement monitoring
     • Optimize incident response
     • Enhance documentation
2. Modernize (Horizon 2). Next, lay the groundwork for a modern platform while enhancing in-place capabilities.
   • Evolve Components
     • Isolate Services
     • Standardize Interfaces
     • Implement Modular Upgrades
   • Enable Services
     • Develop API Library
     • Design and Implement Microservices
     • Optimize Integration
   • Optimize Architecture
     • Modernize Patterns
     • Reduce Technical Debt
     • Implement Scalability Improvements
3. Platform (Horizon 3). Now, you are ready to build the future – a best-in-class platform that will enable and “be” your business.
   • Innovate and Redesign the Business Model
     • Enable new capabilities
     • Create market opportunity
     • Optimize value streams
   • Create Digital Ecosystem
     • Integrate Partner capabilities
     • Build Developer platforms
     • Enable Marketplace
   • Multiply Value
     • Accelerate Innovation
     • Transform cost structure
     • Enable market expansion
