Scoping Your Success: Building a Value-Driven ERP Transformation Plan

Enterprise Resource Planning (ERP) transformations are frequently some of the most capital-intensive and risky endeavors an enterprise can undertake. Unipart recently hosted a deep-dive webinar session answering a fundamental question: How do you design an ERP roadmap that guarantees real-world business value?
 
Led by James Stanley and Phil Kirkham, the session examined how blending modern business process intelligence tools like SAP Signavio with operational practitioners can completely de-risk an implementation from day one.


The Elephant in the Room: Why Do ERP Deployments Stall?

During the session, we ran a live poll asking attendees to identify their single greatest bottleneck to a successful ERP roadmap. The insights revealed a massive shift in how modern organisations are conceptualising system updates:
 
  • Process Complexity & Architecture: 50%
  • Strategy & Executive Sponsorship Alignment: 30%
  • Data Maturity Limitations: 20%
  • Scope & Budget Constraints: 0%
Surprisingly, 0% of our respondents chose scope and budget as their primary concern. Instead, a staggering 50% identified Process Architecture as the single biggest obstacle. Today's organisations realise that automating or migrating broken, poorly defined processes into a new system is simply an expensive exercise in duplicating legacy inefficiency.
 

Case Study 1: Moving from Paper to S/4HANA for a Major Utility

Phil Kirkham shared an excellent operational example focused on a major utility company that chose to insource an extensively outsourced third-party logistics service. Their goals were distinct: improve customer satisfaction metrics and simultaneously scale gross margins.

The utility discovered that sending a maintenance engineer out to a site or home without exact part visibility was costing hundreds of pounds per failed attempt. By mapping operations inside SAP Signavio and moving down an SAP S/4HANA transformation path - specifically introducing Extended Warehouse Management (EWM) - they fundamentally altered their dispatch model.

Instead of manual scheduling, data intelligence allowed them to predict and aggregate repair demands. Materials were pre-packed into customised single totes and staged dynamically for van drivers to pick up seamlessly. The result? A clear, data-backed ROI case built on a unified "clean core" architecture that they could take straight to the executive board with total financial certainty.

Case Study 2: Solving "Workarounds" in a Global Aerospace MRO Environment

James Stanley detailed a secondary case highlighting a highly complex aerospace prime contractor dealing with commercial and defense Maintenance, Repair, and Overhaul (MRO) across distributed UK locations. In this high-stakes arena, agility and operational resilience are non-negotiable requirements to satisfy shifting military deployment scenarios.
 
The company was running an active S/4HANA program but experienced severe post-implementation disconnects: highly manual workarounds, poor warehouse service levels, and a complete breakdown in systemic efficiency. Teams had customised standard processes extensively on paper without matching end-user reality.
 
Unipart stepped in using a practitioner-led model. By combining side-by-side floor observations with Signavio Process Manager, we mapped out the "shadow processes" actually being run on the shop floor. This allowed the client to implement systemic automation (such as RPA) and realign their Master Data. Crucially, it bridged the gap between executive design and shop-floor compliance, shifting the workforce from resisting a system to actively owning its continuous improvement.


The Unipart Formula: Practitioners + Digital Blueprints

A recurring theme throughout the webinar was that software alone cannot fix bad habits. At Unipart, we anchor our consulting work around four major pillars: process improvement, supply chain design, sustainability, and program management. Because our consultants are practitioners who have historically run manufacturing facilities and warehouses themselves, we match software workflows to real human behavior.


Next Steps for Your S/4HANA Journey

If you are planning an upcoming migration, remember these three foundational tenets from our wrap-up summary:
 
  1. Engage Early and Consistently: Do not just gather user requirements at the start and reappear during training. Keep communication transparent across every layer of management.
  2. Enforce a Clean Core: Map early to standard SAP best practices using Process Insights to minimise technical debt and customisation.
  3. Turn Visibility into Action: Process intelligence must trigger structural changes in organisation design, skills alignment, and warehouse layouts, not just sit on a slide deck.
