ERP Implementation Advisory

Are you considering implementing a new ERP system? Lately, I've engaged in a number of discussions regarding the selection of ERPs, their capabilities, and the intricacies of their implementation process. For any business embarking on this journey, it's a significant decision, but one that holds the potential to transform operations. Drawing from my experience as a CFO, I've witnessed the impact that new ERP implementations can have on businesses. It can present remarkable possibilities to streamline operations, enhance decision-making, and stimulate growth. However, it can also come with its own set of challenges and complexities. So, what exactly does it take to ensure a successful ERP implementation? 1️⃣ Process-Oriented Strategy   - Prioritise Processes: Instead of getting lost in features, focus on your business workflows. Identify areas for enhancement, pinpoint bottlenecks, and imagine how the ERP can boost agility.   - Thorough Mapping: Take stock of current processes and spot any gaps. Consider factors like mobile accessibility, real-time alerts, and data analytics as you modernise. 2️⃣ Harnessing Team Potential   - Team Dynamics: The team driving any ERP implementation is of great importance. You will need to gather a diverse group of executives, project managers, end users, and IT specialists. Their collective insights and dedication will be key to a successful implementation.   - Skills and Expertise: Look beyond job titles. Recruit team members with relevant expertise, industry knowledge, and a knowledge of your chosen ERP platform. 3️⃣ Selecting the Right Implementation Partner   - Industry Understanding: Your chosen partner should be able to grasp the fundamentals of your industry. Seek referrals and validate their track record.   - Methodology: What is their implementation approach? It should reflect their own learning and not just be a generic template. 4️⃣ Avoiding Common Pitfalls   - Robust Governance: Establish strong project governance from the outset.   - Clear Scope Definition: Set precise objectives and requirements - avoid scope creep!   - Data Integrity: Ensure your data is clean and reliable.   - Training: Invest in comprehensive user training, during implementation and after.   - Executive Support: Secure backing from leadership. 5️⃣ People-Centric Strategies   - Inclusive Teams: Engage stakeholders at all levels. Everyone should feel accountable for success.   - Promote Collaboration: Foster open dialogue and teamwork.   - Risk Awareness: Acknowledge potential risks and address them early. Oh, and finally, as the CFO ensure the budget is appropriate and costs controlled! Remember, a successful ERP implementation hinges not only on technology but also on people, processes, and collaboration. I would love to hear about your implementation stories and the key to success. 👇 #ERPImplementation #DigitalTransformation #BusinessGrowth #CFOInsights 

🔧 ERP Implementation: It’s Not Just a Project, It’s a Journey! As an ERP Implementation Consultant with 4+ years of experience and having led 8–9 end-to-end ERP implementations, I’ve learned one thing for sure — a successful implementation is never about just installing software. It’s about structure, clarity, and user readiness. Here’s the roadmap I’ve Learn & followed — the one that actually works 👇 ✅ 1. Requirement Gathering – Plan meetings with each department – Understand their daily processes, pain points & goals. – Request flowcharts of existing workflows – Document everything (trust me, it saves lives later!) ✅ 2. Planning & Scope Finalization – Finalize modules, key deliverables & customizations – Lock timelines & responsibilities ✅ 3. Master Data Collection – The most critical phase – Inaccurate or incomplete data = major reason why ERP fails – Structure it well and get a closure by showcasing imported data ✅ 4. Walkthrough Sessions – Give users a demo of the standard ERP – Helps them realize what exists vs what really needs customization ✅ 5. Configuration & Customization – Configure the ERP as per needs – Develop required customizations and get user confirmation ✅ 6. Testing & Internal Piloting – Test everything! – Run internal pilots for each department before involving users ✅ 7. User Training – Create SOPs, UAT templates, and train department-wise – Clear doubts, correct misconceptions ✅ 8. Practicing Phase – Most ignored, but most important – Users must practice UAT's seriously. No shortcuts here. ✅ 9. Go-Live – Clean up trial data – Upload opening balances, stock, etc. – Start fresh! ✅ 10. Post Go-Live Support – This is like baby care 🍼 – Users are in a new system — guide them patiently – Fast response = high adoption 💡 From my experience, these phases form the foundation of a successful ERP journey. 📩 I’d love to know: What steps do you follow during ERP implementation?

𝐄𝐑𝐏 𝐒𝐞𝐥𝐞𝐜𝐭𝐢𝐨𝐧 & 𝐈𝐦𝐩𝐥𝐞𝐦𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧: 𝐈𝐭’𝐬 𝐧𝐨𝐭 𝐚𝐛𝐨𝐮𝐭 𝐬𝐨𝐟𝐭𝐰𝐚𝐫𝐞 – 𝐢𝐭’𝐬 𝐚𝐛𝐨𝐮𝐭 𝐩𝐞𝐨𝐩𝐥𝐞, 𝐩𝐫𝐨𝐜𝐞𝐬𝐬 & 𝐨𝐰𝐧𝐞𝐫𝐬𝐡𝐢𝐩 Too often, companies underestimate how deeply an ERP system affects their organisation. It’s more than IT — it touches every workflow, department and user. Here’s a strategic breakdown of what to focus on before and during your ERP journey: ✅ 1. 𝐏𝐚𝐜𝐤𝐚𝐠𝐞 𝐒𝐞𝐥𝐞𝐜𝐭𝐢𝐨𝐧: 𝐘𝐨𝐮 𝐬𝐞𝐭 𝐭𝐡𝐞 𝐫𝐮𝐥𝐞𝐬 Start by defining your own criteria — don’t let the vendor lead. Legal and compliance needs (e.g. e-invoicing, tax rules) Functional MoSCoW analysis for both AS-IS and TO-BE Clear business drivers for change: growth, process harmonisation, cost, local vs global TCO & ROI 🌍 𝘙𝘰𝘭𝘭𝘪𝘯𝘨 𝘰𝘶𝘵 𝘢𝘤𝘳𝘰𝘴𝘴 𝘤𝘰𝘶𝘯𝘵𝘳𝘪𝘦𝘴? Align your requirements early, especially when consolidating multiple legacy systems into one global ERP. 💬 2. 𝐓𝐡𝐞 𝐒𝐚𝐥𝐞𝐬 𝐏𝐫𝐨𝐜𝐞𝐬𝐬: Sales sells, but delivery makes it real Be critical in the sales phase. The account manager promises, but the implementation team delivers. 👉 𝘉𝘳𝘪𝘯𝘨 𝘪𝘯 𝘢𝘯 𝘪𝘯𝘥𝘦𝘱𝘦𝘯𝘥𝘦𝘯𝘵 𝘤𝘰𝘯𝘴𝘶𝘭𝘵𝘢𝘯𝘵 to challenge assumptions, safeguard your interests and help define realistic scopes and expectations. 🛠️ 3. 𝐈𝐦𝐩𝐥𝐞𝐦𝐞𝐧𝐭𝐚𝐭𝐢𝐨𝐧: 𝐈𝐧𝐯𝐨𝐥𝐯𝐞 𝐮𝐬𝐞𝐫𝐬 𝐞𝐚𝐫𝐥𝐲 𝘈𝘥𝘰𝘱𝘵, 𝘥𝘰𝘯’𝘵 𝘢𝘥𝘢𝘱𝘵. The organisation must embrace the system — not the other way around. Key users should participate in workshops, data prep, and design decisions. This avoids late-stage surprises (aka "skeletons in the closet"). 🔄 4. 𝐂𝐡𝐚𝐧𝐠𝐞 𝐌𝐚𝐧𝐚𝐠𝐞𝐦𝐞𝐧𝐭 𝐢𝐬 𝐧𝐨𝐭 𝐨𝐩𝐭𝐢𝐨𝐧𝐚𝐥 It runs parallel to implementation — not after. 🎯 𝘌𝘯𝘨𝘢𝘨𝘦 𝘬𝘦𝘺 𝘶𝘴𝘦𝘳𝘴 𝘦𝘢𝘳𝘭𝘺, train them well, and make them ambassadors. Their ownership ensures smoother UAT, go-live and post-go-live support. 📝 5. 𝐃𝐨𝐜𝐮𝐦𝐞𝐧𝐭 𝐞𝐯𝐞𝐫𝐲𝐭𝐡𝐢𝐧𝐠 Every choice, configuration and exception should be documented. Start building training material as early as possible — don’t wait until the end. 🚦 6. 𝐂𝐮𝐭-𝐨𝐯𝐞𝐫 & 𝐆𝐨-𝐥𝐢𝐯𝐞: 𝐏𝐥𝐚𝐧 𝐢𝐭 𝐥𝐢𝐤𝐞 𝐚 𝐜𝐚𝐦𝐩𝐚𝐢𝐠𝐧 Create a clear go-live timeline with a RACI matrix. Define who does what, and ensure all levels — including the floor — are informed and aligned. 📅 𝘋𝘰𝘯’𝘵 𝘧𝘰𝘳𝘨𝘦𝘵 𝘩𝘰𝘭𝘪𝘥𝘢𝘺𝘴 𝘢𝘯𝘥 𝘱𝘦𝘢𝘬 𝘱𝘦𝘳𝘪𝘰𝘥𝘴. A calm go-live is a successful one. 📈 7. 𝐏𝐨𝐬𝐭-𝐆𝐨-𝐋𝐢𝐯𝐞 𝐎𝐩𝐭𝐢𝐦𝐢𝐬𝐚𝐭𝐢𝐨𝐧 Form a dedicated optimisation team to manage improvements and fine-tuning. Make a clear distinction between critical issues and functional refinements. 💡 𝐅𝐢𝐧𝐚𝐥 𝐭𝐡𝐨𝐮𝐠𝐡𝐭: ERP is never the goal. It’s a tool to support better business execution — when done with the right process, people and mindset. Have you been through an ERP transformation recently?

1,000 ERP implementations. 1,000 lessons learned. When I started, I made rookie mistakes. Missed requirements. Rushed testing. Underestimated change management. We see this often—especially in professional services. The result? Confusion, rework, lost hours. Sound familiar? But here’s what actually works: → Structured planning from day one → Real-world testing before go-live → Clear change management for every user group → Start data migration ASAP No shortcuts. Not after 10 projects. Not after 1,000. Every project reinforced the basics: - Gather requirements with the real users (not just the loudest voices) - Test with real data (not just demo sets) - Align stakeholders early and repeat often - Don't underestimate data migration The good news? Mastering these steps means predictable outcomes, better margins, and happier teams. ERP isn’t just tech—it’s a transformation for your people, your processes, your bottom line. We’ve seen it happen over and over. The projects that skip the basics always pay more—sometimes for years. If you’re rolling out ERP, don’t shortcut the essentials. How does your team keep project planning and testing front and center? Lessons learned welcome.

Listening to my network, there seems to be a rush to complete ERP migrations, as fast as possible, with SAP S/4HANA plans driving most of it. But an ERP system is more than just an IT upgrade. It’s a chance to redesign how your business operates and build a solution architecture that supports agility and innovation. While necessary, these migrations often become redundant without proper alignment to business goals. Something, I've seen happen! Here some get rights to consider: ◉ 𝗔𝗹𝗶𝗴𝗻 𝗯𝘂𝘀𝗶𝗻𝗲𝘀𝘀 𝗮𝗻𝗱 𝘁𝗲𝗰𝗵 𝗴𝗼𝗮𝗹𝘀 Ensure that IT and business leaders are on the same page. ERP systems serve broader business objectives, such as innovation, improving procurement strategies, and enhancing supplier relationships. ◉ 𝗙𝗼𝗰𝘂𝘀 𝗼𝗻 𝗼𝘂𝘁𝗰𝗼𝗺𝗲𝘀, 𝗻𝗼𝘁 𝗷𝘂𝘀𝘁 𝘁𝗼𝗼𝗹𝘀. Instead of getting caught up in the technology itself, be clear about the business benefits you'd like to achieve. New ERP functionality can be of support to achieve goals like efficiency, cost reduction, and agility. ◉ 𝗦𝗶𝗺𝗽𝗹𝗶𝗳𝘆 𝘄𝗼𝗿𝗸𝗳𝗹𝗼𝘄𝘀 𝗮𝗻𝗱 𝗽𝗿𝗼𝗰𝗲𝘀𝘀𝗲𝘀 𝗲𝗻𝗱-𝘁𝗼-𝗲𝗻𝗱 Don't just migrate complex, outdated processes but streamline them end-to-end. Reevaluate processes for efficiency and desired outcomes. ◉ 𝗜𝗻𝘃𝗲𝘀𝘁 𝗶𝗻 𝗰𝗵𝗮𝗻𝗴𝗲 𝗺𝗮𝗻𝗮𝗴𝗲𝗺𝗲𝗻𝘁 - 𝗻𝗼𝘁 𝗷𝘂𝘀𝘁 𝗶𝗻 𝘁𝗿𝗮𝗶𝗻𝗶𝗻𝗴 ERP migrations often fail due to poor user adoption. Beyond training, invest in communication & ongoing support showing the value and relevance of the system to users. ◉ 𝗜𝗻𝘃𝗼𝗹𝘃𝗲 𝗰𝗿𝗼𝘀𝘀-𝗳𝘂𝗻𝗰𝘁𝗶𝗼𝗻𝗮𝗹 𝘁𝗲𝗮𝗺𝘀 ERP impacts every area of the business, so cross-team collaboration is essential. Involve stakeholders from finance, procurement, IT, and operations ensures the system meets everyone’s needs. ◉ 𝗙𝗼𝗰𝘂𝘀 𝗼𝗻 𝗱𝗮𝘁𝗮 𝗾𝘂𝗮𝗹𝗶𝘁𝘆 - 𝘄𝗶𝘁𝗵𝗼𝘂𝘁 𝗰𝗼𝗺𝗽𝗿𝗼𝗺𝗶𝘀𝗲 An ERP system is only as good as the data it processes. Ensure that data is clean, consistent, and reliable before migration. Dirty or incomplete data is one of the biggest challenges post-go-live. ◉ 𝗣𝗿𝗶𝗼𝗿𝗶𝘁𝗶𝘀𝗲 𝗦𝘆𝘀𝘁𝗲𝗺 𝗳𝗹𝗲𝘅𝗶𝗯𝗶𝗹𝗶𝘁𝘆 𝗮𝗻𝗱 𝗖𝗼𝗺𝗽𝗼𝘀𝗮𝗯𝗶𝗹𝗶𝘁𝘆 Choose an architecture which allows for future-proofing and integration of new features, scalability and integration. Business models evolve, and your ERP must evolve with them." ◉ 𝗦𝗲𝘁 𝗿𝗲𝗮𝗹𝗶𝘀𝘁𝗶𝗰 𝘁𝗶𝗺𝗲𝗹𝗶𝗻𝗲𝘀 - 𝗶𝘁'𝘀 𝗻𝗼𝘁 𝗴𝗼𝗶𝗻𝗴 𝘁𝗼 𝗯𝗲 𝗾𝘂𝗶𝗰𝗸 𝗶𝗳 𝘁𝗿𝗮𝗻𝘀𝗳𝗼𝗿𝗺𝗮𝘁𝗶𝘃𝗲 Don’t rush an implementation. ERP migrations are complex and require time to integrate properly. A phased approach allows for troubleshooting and mitigates a risk for failure. ❓Any other "get rights" i missed and you would add from your experience. #erp #businesstransformation #migration #sap4hana

Culture eats ERP for breakfast, and most leaders don’t even know it’s on the menu. ERP implementations succeed or fail long before the first workshop or line of code is written. Leadership sets the tone and often unknowingly sets traps. Here’s what I often see: Leaders chase flashy project names instead of aligning culture and strategy. They skip defining actionable business objectives. They select advisors blindfolded because they don’t know what they don’t know. They ignore change management, requirements governance, and stakeholder buy-in. They assume their already overburdened team can “just figure it out.” The result? Overruns, resistance, and a system that doesn’t deliver value. How do you mitigate these risks? Start with clarity: Define business strategy and objectives before tech. Vet advisory partners like you would a CFO, experience matters. Build governance for requirements and change management early. Allocate time and upskill your team; don’t just hand them a new system and hope for the best. If this resonates, share it with a leader who’s about to start an ERP journey. It might save them millions.

Why Do 70-75% of ERP Implementations Fail? The "Three C's" That Organizations Must Manage Enterprise Resource Planning (ERP) systems are essential for improving efficiency, yet 70-75% of implementations fail. Common reasons include immature data, poor requirements, complex legacy systems, and over-customization. Suppliers often oversell benefits and underestimate the effort required. However, technical challenges can usually be resolved with time and expertise. The real issues lie in what I call the "Three C's" of ERP implementations, which organizations must manage internally. The Three C's of ERP Implementations: 1.    Capacity Organizations often struggle to balance ERP implementation with regular operations. Underestimating the workload leads to resource strain, missed deadlines, and project failure. It's vital to assess and allocate resources effectively to handle both ERP tasks and daily operations. 2.    Capability Success requires the right people making informed decisions. Beyond project managers, organizations need experienced functional and process owners. Poor decision-making due to lack of expertise often derails projects, so placing the right talent in key roles is essential. 3.    Change Management Many ERP systems fail due to poor change management. Employees often resist new processes, especially if they’ve used legacy systems for years. Without proper training and support, staff may revert to inefficient methods. Strong change management ensures smooth transitions and user adoption. Overcoming the Three C’s with an Organizational Readiness Assessment To successfully manage the "Three C's," organizations should conduct an "Organizational Readiness Assessment" before even the implementation even starts - at the time of strategy planning. This process evaluates resource capacity, decision-making capabilities, and change management plans. Identifying and addressing gaps helps ensure the organization is ready for ERP implementation. Conclusion ERP failures often stem from internal challenges rather than technical ones. The "Three C's"—Capacity, Capability, and Change Management—are critical factors that organizations must manage to ensure success. By conducting an Organizational Readiness Assessment and addressing gaps, companies improve their chances of successful ERP adoption. Ultimately, ERP success depends, amongst other things, on whether the organization is prepared for the change.

We got a call from a large manufacturing group in the UAE. They had gone live with ERP 6 months ago. Finance was still doing reconciliations in Excel. Inventory reports took 3 hours to compile. No one trusted the data. Everyone blamed the system. The irony? The ERP was technically “implemented.” We were brought in to fix it. Here’s the exact 3-𝐬𝐭𝐞𝐩 𝐭𝐮𝐫𝐧𝐚𝐫𝐨𝐮𝐧𝐝 𝐟𝐫𝐚𝐦𝐞𝐰𝐨𝐫𝐤 we used (that most consultants skip): 1. 𝐑𝐞𝐛𝐮𝐢𝐥𝐝 𝐁𝐮𝐬𝐢𝐧𝐞𝐬𝐬 𝐀𝐥𝐢𝐠𝐧𝐦𝐞𝐧𝐭 (𝐍𝐨𝐭 𝐉𝐮𝐬𝐭 𝐖𝐨𝐫𝐤𝐟𝐥𝐨𝐰𝐬)  → First meeting was not with IT. We sat with Finance, Supply Chain, and Ops leaders to map pain vs. process. 𝐖𝐡𝐚𝐭 𝐰𝐞 𝐟𝐨𝐮𝐧𝐝? Core processes were shoehorned into the system. Nobody mapped them against real-world cycles. 𝐅𝐢𝐱: We restructured key flows based on actual business needs—not system defaults. 2. 𝐂𝐥𝐞𝐚𝐧 𝐭𝐡𝐞 𝐌𝐚𝐬𝐭𝐞𝐫 𝐃𝐚𝐭𝐚 (𝐍𝐨𝐭 𝐉𝐮𝐬𝐭 𝐏𝐚𝐭𝐜𝐡 𝐑𝐞𝐩𝐨𝐫𝐭𝐬)  → Sales was struggling with mismatched SKUs.  → Finance had duplicate vendors and unlinked POs. 𝐈𝐧𝐬𝐭𝐞𝐚𝐝 𝐨𝐟 𝐛𝐥𝐚𝐦𝐢𝐧𝐠 𝐮𝐬𝐞𝐫𝐬, 𝐰𝐞 𝐫𝐚𝐧 𝐚 𝐟𝐮𝐥𝐥 𝐦𝐚𝐬𝐭𝐞𝐫 𝐝𝐚𝐭𝐚 𝐚𝐮𝐝𝐢𝐭: ✓ Duplication heatmaps ✓ Inconsistencies by module ✓ Cross-functional reconciliation tasks 𝐅𝐢𝐱: Built validation rules + cleansing pipelines. Tied ownership to teams. 3. 𝐑𝐞𝐝𝐞𝐬𝐢𝐠𝐧 𝐭𝐡𝐞 𝐆𝐨𝐯𝐞𝐫𝐧𝐚𝐧𝐜𝐞 𝐋𝐚𝐲𝐞𝐫  → There was zero change control.  → Anyone could raise config requests.  → No one tracked impact or training. 𝐖𝐞 𝐢𝐧𝐬𝐭𝐚𝐥𝐥𝐞𝐝 𝐚 𝐥𝐢𝐠𝐡𝐭 𝐛𝐮𝐭 𝐟𝐢𝐫𝐦 𝐠𝐨𝐯𝐞𝐫𝐧𝐚𝐧𝐜𝐞 𝐦𝐨𝐝𝐞𝐥: ✓ Change advisory board with business+IT ✓ Measured impact before rollout ✓ Micro-trainings for every major change 𝐅𝐢𝐱: Business users re-engaged. System stability returned. 6 weeks later, the CFO said something I’ll never forget: “This is the first time the ERP feels like ours, not something pushed on us.” And that’s what real ERP rescue looks like. Not flashy. Not fast. But real. ♻️ 𝐑𝐄𝐏𝐎𝐒𝐓 𝐒𝐨 𝐎𝐭𝐡𝐞𝐫𝐬 𝐂𝐚𝐧 𝐋𝐞𝐚𝐫𝐧.

Many of our clients are either going through or preparing for an ERP implementation. Having seen these programs across industries—the good, the bad, and the ugly—one piece of guidance I always give: Co-source your ERP implementation from the start. Too often, companies rely solely on one firm to lead the program, only to realize that technical implementation alone won’t drive success. The larger the company, the more critical it is to take a balanced approach. Here’s what we recommend: Firm 1: System Integrator – Focuses on the ERP’s technical implementation, including system configuration, data migration, and integration. Firm 2: Business Integrator – Ensures the system and related business processes align with transformation goals, operating model optimization, and benefits realization. This co-sourcing model de-risks the program, ensures technical and business alignment, and delivers a system and processes that are fully integrated and built for long-term success. The image below highlights some of the key benefits we’re seeing in co-sourced ERP programs where we serve as the Business Integrator. A hill I’m willing to die on—co-source your ERP program.

The ERP implementation: $600K. The integrations to make it actually work: $780K. Yeah. You read that right. The "duct tape" cost more than the engine. Here is the anatomy of a $1.4M mistake. The client wanted a clean, modern cloud ERP. But they refused to let go of their legacy baggage The custom CRM (Sunk cost fallacy). The WMS (Change aversion). The Billing System ("Accounting likes it"). I asked the CFO: "Why not consolidate these into the ERP?" His answer: "We don't want to disrupt those areas right now." Famous last words. To avoid "disruption," we built a Frankenstein monster: CRM Sync ($180K): Because sales wouldn't switch. Warehouse Middleware ($220K): Because the WMS had no API. E-commerce Bridge ($150K): Custom mods on Shopify broke standard connectors. HR & Billing Feeds ($230K): Bridging ancient systems to modern tech. Total Integration Cost: $780K. The Aftermath (6 Months Later): Three integrations failed. Not because the code was bad, but because the ecosystem changed. Shopify updated → Integration broke. WMS vendor patched → Middleware crashed. CRM team added a field → Data sync failed. I told the CFO: "You paid more to keep your old systems than you would have to replace them." If we had consolidated everything into SAP: Total Cost: ~$900K. Single point of truth. Unified support. Instead, they paid $1.475M to maintain six points of failure. Every integration you build is technical debt. It will break. It will slow you down. It will cost 3x more than you budget. If you are implementing an ERP to simplify your business, don't complicate it with eight integrations. Consolidate first. Integrate only when you absolutely must. Before you sign that SOW, run the math Cost to Integrate + Maintenance vs. Cost to Replace. If integration costs more, kill the legacy system. Don't trap yourself in integration hell just to avoid an awkward conversation with the Sales VP.
