Example projects

The problem, what we did, the result, and what we took away.

SAP Programme Manager · Finance process redesign

From 45 days to 2

Problem: A global cargo-handling manufacturer's invoicing ran on fragmented SAP processes, tying up cash and finance teams.
Impact: 45 → 2 days invoice lead time; financial performance up around 35%.
What we learned: Fix the process before the system. Most of the gain came from removing hand-offs, not from new software.

We'd love to do this again for a finance or shared-services function.

Lead Product Owner · KYC / AML data

One source of truth for compliance

Problem: A Dutch bank's compliance reviews pulled data from many systems, slowing onboarding and increasing regulatory risk.
Impact: ~40% faster compliance reviews after a centralised KYC/AML data lake.
What we learned: Data ownership matters more than architecture. Agreeing who owns each field unblocked the build.

Relevant to any regulated business modernising KYC, AML or GDPR controls.

Senior Product Owner · SAP S/4HANA migration

A $10M migration for a grid operator

Problem: A European energy grid operator needed to move to S/4HANA without disrupting regulatory reporting.
Impact: +40% regulatory reporting accuracy on a programme of around $10M.
What we learned: Treat the regulator as a stakeholder from day one; reporting requirements shaped the data design.

A great fit for utilities and infrastructure businesses planning S/4HANA.

Lead Data Project Manager · Payroll integration

SAP and Workday, one payroll

Problem: A global energy company ran payroll across SAP and Workday with manual reconciliation and recurring errors.
Impact: +25–40% payroll accuracy and efficiency after unifying the data flows.
What we learned: Payroll change is people change. Clear communication with HR and employees was as important as the integration.

We'd welcome another HCM / payroll integration challenge.

VP Programme Manager · Data procurement

250+ supplier projects, $25M of value

Problem: A global bank was buying market and reference data without a joined-up view of cost, contracts or usage.
Impact: $15M saved plus $10M of new revenue across 250+ sourcing projects.
What we learned: Visibility is the first saving. A single contract and usage register paid for the programme early.

Ideal for procurement, vendor management and data-cost programmes.

Senior Product Owner / Project Manager · Cloud migration

Multi-cloud for a retail group

Problem: A major food retail group needed to move workloads to a multi-cloud / Azure estate while keeping stores and supply chain running.
Impact: +20–25% operational efficiency after migration.
What we learned: Migrate by business capability, not by server list, so each release delivers something users notice.

Relevant to retail and logistics groups with hybrid estates.

HR Operations · Digitalisation & absence management

De-risking HR admin across two countries

Problem: A leasing and mobility group ran HR administration across Paris and Amsterdam with manual, error-prone processes and limited absence tracking.
Impact: Digitalised core HR admin and introduced structured absence (verzuim) tracking, reducing risk and manual effort.
What we learned: Small, well-chosen tools beat a big platform when the priority is control and compliance.

A natural fit for HR operations teams in regulated, multi-country businesses.

Senior Change Manager · M&A and TUPE

People change through acquisitions

Problem: A UK bank integrating and divesting businesses needed TUPE processes and employee communications handled cleanly and lawfully.
Impact: Multiple transfers delivered on time with employees informed, consulted and transitioned.
What we learned: Trust is built in the consultation meetings, not the project plan.

Relevant to any organisation facing restructuring, carve-outs or integration.
