The 9Nation difference

Every program has plenty of people accountable for the build. Someone independent has to be accountable for the whole outcome.

That's the seat I take, executive program leadership with no software to sell and no incentive but your go-live. I run governance, cutover, and change at the scale where a single bad quarter costs millions, and I tell you the truth the status deck won't.

How I work

From selection to hypercare, accountable the whole way.

Selection

The right platform and SI, with scorecards and SOWs that protect you.

Phase Zero

Assessment, business case, and governance that de-risk the program before build.

Build & govern

Executive steering, decision discipline, and a partnership managed to scope.

Test & IV&V

Independent validation, payroll parallels, and an honest go/no-go.

Go-live

Cutover command center, contingency, and a controlled landing.

Hypercare

Stabilization through the first real cycles, then a Center of Excellence.

What clients say

Trusted in the room where it counts

David was the only person in the room willing to tell us the program was off track while we could still fix it. Vendors said it was possible, but they were only looking at their own resources. That candor saved our go-live.

CHRO · Multi-hospital health system

Deployment went surprisingly smoothly. David's calm, decisive approach, independent of our SI, gave us confidence we were on the right track.

SVP, Finance · Global logistics organization

We brought David back for a second phase after he delivered a successful big-bang implementation 3 years ago. Once again, he delivered. His leadership on our Review-and-Recommend ERP initiative was exactly what our steering committee needed to make the right call.

A status report that's green on the outside and red on the inside is the most expensive document in your program.

Insights

Field notes from the program trenches

Grants and student on Workday: the modules where programs stall

HCM and Finance are the easy part. Grants and Student are where research-university programs stall. Where they break, how they wire into the ERP, and what separated the go-lives that worked.

The cutover playbook: how Workday and ERP go-lives get done

18 months of build, decided in the last 10 days. The tenant chain, the freeze, the go/no-go, the command center, the rollback call, and the first payroll. The tactical version.

The client-side PMO

Your implementer is accountable for their scope. Nobody owns your whole program unless you make somebody accountable. The five accountabilities, and how to stand one up in 90 days.

ERP analytics: from report factory to decision engine

Governance, the semantic layer, staying in suite or going best of breed, and what changes in 2027 when agents start reading the data first. Workday Prism, Oracle, and SAP.

Implementing payroll: a VP of Payroll's guide

10 payroll modules, the one decision to get right in each, where they break, and what AI actually changes. Written for the leader who has to make payday land.

Implementing supply chain ERP modules: a CSCO's guide

10 supply chain modules, the one decision to get right in each, where they break, and what AI actually changes. Written for the leader who has to keep product moving.

Implementing HCM and HR ERP modules: a CHRO's guide

10 HR modules, the one decision to get right in each, where they break, and what AI actually changes. Written for the HR leader who has to own the result.

Implementing finance ERP modules: a CFO and controller's guide

9 finance modules, the one decision to get right in each, where they break, and what AI actually changes. Written for the finance executive who has to own the outcome.

Data conversion and integrations: the workstream that decides your go-live

The software is rarely the risk. The data going in and the connections coming out are. How to scope, own, sequence, and reconcile them so your date holds.

What Workday really costs

Workday publishes no price list. Over 5 to 10 years the subscription is under half of the total. How it prices, where the money hides, and the levers that move the number.

Negotiating with your System Implementer

The contract is the operating system for the whole program, and your leverage is gone the moment you sign. The 10 areas to negotiate before you do.

Workday is one system. Your organization is not.

Where unified HR and Finance deployments strain, the data model, the calendars, the politics, and how to govern the seams.

The watermelon status report

Why green-on-the-outside programs fail, and how to read the red underneath before it costs you a quarter.

Choosing and managing your SI

The independent-voice approach to selecting your SI, shaping the SOW, and making the partnership work.

Questions

The things executives ask me first.

Why independent, what does that add alongside our SI?

Your SI is accountable for their scope, and a good one delivers it. What they can't be is the independent senior voice on your side of the table. I take that seat, running governance, cutover, and change, so decisions get made with the whole program in view, not one workstream.

How do you work alongside our existing SI?

As a partner, not a replacement. I sit on the client side, keep the program honest, accelerate decisions, and make sure knowledge transfers to your team so you own the platform when the SI rolls off.

When should I bring you in?

Earlier is cheaper. Phase Zero and selection are ideal. However, I'm as often brought in mid-flight to reset a stalled program or run an independent go-live readiness assessment.

What platforms do you cover?

Workday-deep, platform-agnostic, with depth in Salesforce, ServiceNow, PeopleSoft, and ERP across 16 industries.

How do engagements start?

Usually with a short, candid call and a focused read on where your program stands. Book a 15-minute intro call to start.
