Notes on ERP strategy and the automation of IT itself.

Your Finance AI Is Only as Good as Your Data: What SAP's Acquisition Spree Reveals About Why Autonomous Finance Stalls

SAP spent billions on Dremio, Prior Labs and Reltio to solve the real bottleneck: enterprise data. Here's what that means before you invest in AI for finance.

When the ERP configures itself: What SAP's agentic 'Autonomous Enterprise' push means for S/4HANA program staffing and the SAP career path

SAP's Autonomous Enterprise push will compress S/4HANA delivery hours by 20–35%. Here's the FICO exposure map: which skills commoditise and which appreciate.

Run — Deciding when support can take over from the project team

The run phase rarely fails for lack of support competence. It fails due to arbitrary calendar ceilings on hypercare, cognitive handoff failures, and a ticketing trap where SLA metrics hide operational stagnation.

Cutover — Switching off the old system with no time left to fix a mistake

Cutover has a reputation for being the most choreographed phase of an ERP program, documented hour by hour. It is also the least understood: the document reassures without guaranteeing anything. The only thing that saves a cutover is the agency of the person driving it.

Change — Preparing the business

Change management doesn't fail for lack of method. It fails because programs don't invest in it seriously, starting with who gets picked as a key user, and the bill arrives after go-live.

Reporting — Building the same reports more than once

Reporting is the workstream of rework. On a greenfield S/4HANA program, the same reports get rebuilt several times for three avoidable reasons: technology chosen too new, a build started on moving data, and no common CDS foundation.

Series · Inside a Large ERP Program · Part 9 of 13

Data migration — Moving and cleaning the data the whole program depends on

Data migration almost never fails on the mechanics of moving data. It fails on legacy data quality, systematically underestimated, and on a workstream caught between the quality below it and the rules changing above it.

Authorizations — Assigning roles too early, and rebuilding them later

On a greenfield S/4HANA program, the authorization stream rarely fails because it started late. It fails because it mapped the organization finely before the transactions were stable. Cut wide first, refine after.

Testing — Proving the system works before you turn it on

Testing looks like an objective measure of whether a system is ready. It isn't. A passed test certifies only what someone decided to test, and that decision is made earlier, quietly, and often for the wrong reasons.

Series · Inside a Large ERP Program · Part 6 of 13

Build — Turning design decisions into configuration and code

The build phase rarely breaks inside a link—the config, the code, or the test. It breaks at the seams between them. Distributed delivery doesn't invent that flaw; it turns each seam into a time zone and a ticket.

Design — Trading off fit-to-standard against custom requirements

Fit-to-standard isn't decided in design workshops, where consultants have no authority to enforce it. It's decided in the arbitration committee, where whoever wins the gap is rarely the one who pays for it.

Selection — Choosing the vendor, the integrator, and the contract

An RFP scores the quality of a vendor's pre-sales, not their delivery. The real decision sits in the blind spots of your grid: price, flexibility, contract incentives, and who actually shows up.

Program architecture — Designing the landscape, the integrations, and the extensions

ERP architecture rarely fails on technical grounds. It fails because landscape, integration, and extension decisions get made fast and untraced, then compound into debt.

Scoping — Deciding what's in scope before anyone talks about software

The composition of the scoping team is the real scope. Who sits in the room decides what stays out of it, and the off-scope is never random: it's the depth only a doer sees.

Series · Default Is a Decision · Part 1 of 4

Big-Bang or Phased Is the Wrong Argument. Here's the One That Decides the Outcome.

The big-bang vs phased debate is tractable on a slide, which is exactly why it absorbs committees. What actually decides an ERP program runs underneath the sequence: maturity, data, and a scope that holds still.

Series · What AI Actually Replaces · Part 2 of 2

The Question Isn't What AI Replaces. It's What Your IT Department Becomes When Execution Is Free.

When execution becomes nearly free, IT's value doesn't vanish. It moves to what doesn't execute: judgment, context, and the orchestration of both. A CIO's extrapolation.

Series · What AI Actually Replaces · Part 1 of 2

AI Won't Replace Your SAP Consultants. It Will Replace the Layer You Never Needed.

AI isn't coming for SAP expertise. It's coming for the friction layer — the roles that exist only because information travels badly. The distinction it draws is judgment versus relay.

Most S/4HANA migrations don't speed up close — because full Universal Journal activation is skipped. Here's the 3-phase path from 5 days to a 2-day close.

Series · The Real Point of Failure · Part 3 of 3

Nobody Owns an ERP Program. The Decision Chain Does.

Hunting for the single owner of an ERP program produces exactly the broken chain it was meant to prevent. Ownership lives in a sequence of roles, not a person.

Governance Is Not a Committee, It's a Decision Chain

A governance committee can be perfectly assembled and still be theater. Three structural fixes turn a committee that meets into a chain of decision that holds.

Why ERP Programs Almost Never Fail for Technical Reasons

ERP programs rarely fail in the technology. They fail in the decision chain, months before the symptoms surface on a developer's screen. Here is the mechanism.
