How to phase an ERP implementation
Choosing a first phase that solves a real problem, sizing phases so each carries its own business case, and the dependencies that force sequence.
Read moreERP programmes fail when they try to replace everything at once. We implement Dynamics 365 in phases anchored to a specific operational problem — month-end, inventory accuracy, order-to-cash — so each stage pays for itself before the next one starts.
Rarely one dramatic failure. Usually the accumulation of workarounds that everyone has stopped noticing.
Finance consolidates from several systems by spreadsheet. By the time figures are agreed they are too old to act on, and someone always disagrees with them.
Inventory is maintained in more than one place with manual adjustments. Purchasing over-orders defensively and working capital sits on a shelf.
The same information is entered in sales, then operations, then finance. Every re-key is a chance to introduce an error nobody finds until a customer complains.
Adding a location, a product line or a currency means more manual work rather than a configuration change, so expansion carries a hidden headcount cost.
An ERP programme should be judged on operational metrics, not go-live. If month-end is not faster and inventory is not more accurate, the implementation was technically successful and commercially pointless. If month-end is not faster and inventory is not more accurate
Targets are set per phase against your current baseline, and reported after each go-live.
Typical reduction in month-end cycle time once consolidation, reconciliation and manual journals move onto one platform.
Target stock record accuracy after unified inventory management, cycle counting and the removal of parallel spreadsheets.
Typical reduction in duplicate data entry across order, fulfilment and finance processes once integration replaces handoffs.
Order status, stock position, margin and cash visible without waiting for a report to be prepared and circulated.
Each phase scoped so its benefit is measurable and its cost recoverable, rather than a single business case spanning years.
Every process mapped with a named owner and documented exception handling, which is usually the first time this has existed.
How to read these: the figures above are typical ranges we plan and measure against, not guarantees. In your first engagement we agree the baseline, the target and the measurement method in writing, then report against them.
New implementations, rescuing struggling ones, and improving systems that went live years ago.
We start with the process causing the most pain, prove the platform there, then extend — rather than a two-year programme with one terrifying date.
ERP only delivers value when it stops being an island. Integration with CRM, e-commerce, warehouse and reporting is scoped from the start.
Training built on your processes, champions in each team and hypercare through the first close — because the first month-end is the real go-live.
Individually scoped work packages. Most programmes combine a discovery phase with two or three delivery phases.
Mapping how the operation actually runs, including the workarounds, then assessing fit against standard platform capability before anything is configured.
Sequencing modules and processes so each phase solves a real problem, carries its own business case and can be approved on its own merits.
Chart of accounts, dimensions, approval workflows, period close process, inventory and purchasing configured to your operating model.
Master data cleansing, mapping, load and reconciliation with documented evidence that balances, quantities and open items match the source.
Building the interfaces to CRM, e-commerce, warehouse, payroll and reporting systems that are staying, so re-keying genuinely stops.
Operational and financial reporting delivered with the implementation, so the first close does not depend on exports and spreadsheets.
Independent assessment of a programme that has stalled or gone live badly: root cause analysis, remediation plan and a realistic route to stability.
Manufacturing, distribution, professional services, construction and nonprofit operating models each need different costing, project accounting and inventory treatments.
Standard platform first, phased delivery, and customization only where a genuine differentiator justifies it.
Process mapping with the people doing the work, plus data quality assessment and integration inventory.
Agree phase boundaries, the target operating model and where standard process will replace current practice.
Configuration design, integration architecture, migration approach and reporting requirements documented and signed off.
Build, migrate, test with real data and real users, then go live with hypercare through the first period close.
Post-close review, adoption measurement and the next phase scoped against what the first one actually taught you.
We push back on customization. Every modification adds upgrade cost and testing burden forever. Where a request reflects habit rather than genuine differentiation, we will propose the standard process and explain the trade-off plainly.
ERP is the category with the most spectacular failures, and the failure modes are well understood.
You approve and benefit from each stage separately. If the relationship or the plan is not working, you have not committed your entire capital budget.
Our functional team includes people who have closed books, managed inventory and chased purchase orders, so process conversations are practical rather than theoretical.
ERP value depends on what it connects to. Because we also do data and integration work, the interfaces are in scope rather than someone else's issue.
Success is a faster close and accurate stock, not a completed implementation. Targets are agreed before build starts.
Illustrative engagements, written in the structure we use for real case studies.
A growing manufacturer moved from disconnected accounting and operational processes to one platform for finance, inventory, purchasing and reporting.
Phase one targeted stock accuracy alone. Getting that right made every subsequent phase easier to justify and easier to deliver.
