ERP projects fail when governance, data, and change are mismanaged. Common causes include: 

• Misaligned expectations between business and IT 

• Weak project governance and poorly defined teams 

• Poor data migration readiness and inadequate testing 

• Unsuitable, one-size-fits-all implementation methodology 

• Insufficient organizational change management (OCM) 

Pemeco prevents failure with its Milestone Deliverables methodology — a framework that distills complex ERP projects into a small set of tangible, trackable deliverables. This method integrates governance, process design, OCM, data migration, and testing to align ERP with business strategy.

An ERP implementation plan must cover process, people, data, and technology. Key planning documents include: 

• Project charter – vision, objectives, authority, and scope 

• Project schedule – milestones, dependencies, and resourcing 

• Financial plan – budgets, cost controls, reporting 

• Change management plan – communications, training, stakeholder engagement 

• Test plan – unit, integration, and user acceptance testing 

• Data migration plan – cleansing, mapping, migration readiness 

• Technical plan – infrastructure, integrations, and architecture 

Pemeco ties these plans to Milestone Deliverables, making progress transparent, manageable, and easy to govern. 

📌 Explore our ERP Implementation Planning Checklist for details. 

ERP plans should be built around milestone deliverables that make progress visible and manageable. Pemeco’s proven 5-step approach includes: 

1. Establish governance – define accountability and escalation paths 
2. Define requirements – capture processes, roles, and KPIs 
3. Develop the blueprint – align requirements with design, data, and integrations 
4. Phase-gate execution – testing, training, and migration tied to milestones 
5. Track milestone deliverables – clear checkpoints for scope, budget, and timing 

This approach also embeds OCM to guide organizations through the emotional curve of change — from resistance to recovery — ensuring adoption. 

📌 See Pemeco’s Milestone Deliverables infographic for a visual framework. 

ERP implementation usually takes 6–18 months. Timelines depend on: 

• Functional scope of the project – modules, processes, geographies 

• Extent of organizational change – workforce impact, redesign, OCM needs 

• Number of sites and business units in scope 

• Complexity of integrations and customizations 

• Quality of data migration and testing discipline 

• Stakeholder readiness and adoption 

Pemeco keeps projects on track with disciplined planning, governance, and risk management anchored in milestone deliverables. 

ERP success depends on a structured governance model with defined teams. Typical roles include: 

• Executive Committee – ultimate accountability for scope, budget, business case 

• Steering Committee – senior leaders setting direction and resolving roadblocks 

• Project Management – client-side PM (10x the accountability of an integrator’s PM), supported by a solutions architect and PMO 

• Organizational Change Management (OCM) – change leaders driving communication, training, adoption 

• Core Team – cross-functional business leads and super users designing processes and testing solutions 

• Consulting Team – integrator consultants responsible for configuration and technical build 

• Subject-Matter Experts (SMEs) – specialists validating requirements and solutions 

📌 See Pemeco’s Governance and Teams Framework for proven models. 

Your ERP project needs a client-side project manager to govern the whole program. 

• Vendor PMs manage only vendor deliverables. 

• Integrator PMs manage only their consultants. 

• The client-side PM governs everyone — internal staff, integrators, and vendors — and carries ultimate accountability for outcomes. 

Without this role, projects risk vendor-led decisions, missed strategic alignment, and costly overruns. Pemeco advises, coaches, or embeds client-side leadership, but ownership must remain with you.
