Embarking on an RPG-based ERP/MRP system modernization is undeniably complex. But it’s also highly rewarding when aligned with your business’s long-term success. By addressing both the technical and strategic facets, you turn an aging system from a liability into a competitive asset. Let’s outline the 7 steps in a legacy modernization project:
Step 1: Assess Your Legacy Landscape
Start with a frank assessment of your current RPG system. Inventory all modules and their business importance, analyze the code quality (possibly using automated scanners), and identify critical pain points and how well the system can support your future business needs. This step often reveals quick wins and informs the priorities of larger initiatives.
Step 2: Define a Modernization Roadmap
Map out a multi-phase roadmap based on the assessment. Prioritize projects that address the biggest risks and offer the highest business value. Ensure each phase has clear business-aligned goals. This roadmap translates business strategy into tech milestones. Keep it flexible; it can evolve as you learn from each phase and as business conditions change.
Step 3: Secure Buy-In and Budget
Use the roadmap and business case to get official buy-in and budget. Articulate the cost of doing nothing and the benefits and ROI of modernization at each step. With executive sponsorship and allocated budget, you have the mandate to execute the plan with authority and adequate resources.
Step 4: Build the Right Team and Partnerships
Put together a modernization team that blends institutional knowledge with fresh skills. This could mean upskilling internal staff, hiring new talent, and engaging external experts. Assign a strong project manager to coordinate between IT and business stakeholders.
Step 5: Execute in Iterative, Value-Driven Increments
Approach modernization projects in an agile, iterative manner. Deliver smaller increments every few weeks if possible, every few months otherwise, and gather feedback. Each increment should deliver tangible value or learning, which reduces risk and allows the business to start reaping benefits early.
Step 6: Focus on Change Management Throughout
Parallel to technical work, keep executing your change management plan. Continue updating everyone on progress, training users for upcoming changes, and capturing feedback. Monitor adoption of new tools and be ready to adjust.
Step 7: Measure, Adapt, and Evolve
Establish metrics to track the success of modernization against your business goals. Report these wins and be candid about any shortfalls. Use a continuous improvement mindset. A tech strategy aligned with business goals is not a one-and-done project; it’s an evolving program. As new technologies emerge, incorporate them into your roadmap where relevant to the business.
By following these steps, a company with a legacy RPG-based system can methodically transition to a modern, agile technology footing. It’s a journey that addresses immediate risks (like legacy maintenance costs and developer shortages) while setting the foundation for long-term growth and innovation.
