Case study - Enterprise systems

Building a stronger digital operating backbone for PowerGen.

A multi-year programme spanning ERP migration, project management and controls, analytics, information governance, security, custom applications and user adoption across a distributed renewable-energy organisation.

The challenge

Growth had made fragmentation more expensive.

PowerGen's operations depended on multiple systems, spreadsheets, shared information environments and country-specific processes. As the organisation grew, inconsistent structures, duplicated work, difficult reconciliation and limited project visibility became more visible.

The assignment was not a single software implementation. It required an evolving business-systems function capable of stabilising existing platforms, migrating critical data, integrating reporting, strengthening control and creating new applications for processes that standard tools did not adequately support.

My approach

Treat the work as an operating-model programme.

I worked with Finance, Procurement, Projects, Operations and leadership to understand where information originated, how decisions were made, where controls failed and which processes needed standardisation.

I combined hands-on platform administration with requirements analysis, data modelling, product ownership, solution design, testing, documentation, training and vendor coordination across Odoo, Power BI, SQL data sources, Google Workspace, integrations and custom applications.

Start with the processMap the real workflow, decision rights, source data and exceptions before changing the technology.
Design for controlBuild permissions, approvals, validation and auditability into the operating flow.
Connect the dataBring financial, operational and project information into a consistent reporting model.
Stay close to adoptionUse testing, training and support to ensure the design works in real operations.

Transformation workstreams

Work across the full systems lifecycle.

The programme combined platform migration, project delivery, data, control, governance and user capability rather than treating them as separate technology projects.

ERP migration and 30+ application testing

Directed the migration of more than 100 million records from Odoo 14 to 17 with zero operational downtime, then led the Odoo 19 programme and end-to-end testing across 30+ standard, Studio-built and custom applications.

Complete project-management hub

Built a governed workspace connecting project portfolios, WBS plans, schedules, milestones, risks, actions, documents, reporting and cross-functional collaboration.

Project costing and controls

Designed a unified platform linking budgets, procurement, payments, inventory, forecasts, variations, earned value, risks, milestones and executive reporting.

Purchase Requisition application

Designed and built an Odoo Studio application from scratch for internal requests, approvals, procurement hand-offs, status visibility and audit trails.

O&M reporting application

Built a reporting application for O&M services across PowerGen sites, standardising field reporting, site visibility, issue tracking and management oversight.

Intercompany reconciliation

Built an application for cross-entity matching, exception management, supporting documentation, ownership and resolution of intercompany balances.

Analytics and reporting

Built Power BI reporting across operational and financial sources, reducing manual preparation and improving visibility into budgets, costs and project performance.

50+ governed information migrations

Led more than 50 controlled Shared Drive migrations covering archiving, reorganisation, consolidation, permissions, standardisation, retention and migration audit controls.

Email security and access

Aligned SPF, DKIM and DMARC, moved enforcement to reject and raised domain-authentication performance to 98%, alongside phishing response, access review and user-awareness controls.

What changed

Better-integrated systems, clearer ownership and less manual dependency.

Migration at scaleMore than 100 million ERP records migrated without operational downtime.
Custom operational applicationsPurchase Requisition, O&M Reporting and Intercompany Reconciliation applications moved critical workflows into governed systems.
Connected project deliveryProject management, planning, costing, controls and reporting brought into one coherent product direction.
Cost disciplineBusiness-systems expenditure reduced by approximately 40% through negotiation, consolidation and platform optimisation.
Stronger governanceInformation architecture, access controls and migration oversight strengthened across distributed teams.
Internal capabilityMore than 100 employees equipped through practical training, testing and ongoing support.

What this demonstrates

Leadership across strategy, architecture, product ownership and delivery.
