Your S/4HANA program will not fail because you picked the “wrong template.”
It will fail because you staffed the plant-floor last.
After reviewing 950 S/4 jobs this January across the US market, the loudest hiring signal isn’t for generic SAP consultants.
It’s PP / PPDS / MES / QM / EWM / TM roles in aerospace, medical devices, and complex assembly – exactly where bad designs show up as missed shipments and scrap, not in a status report.
What the data is telling us:
→ COOs and Ops leaders are finally pulling S/4 out of the ivory tower and into the plants.
→ The most urgent roles are hybrid: people who understand routings, quality holds, warehouse constraints and S/4 configuration.
→ Programs that staffed FI/CO and “core ERP” first are now scrambling for Manufacturing Deployment SMEs, PP/MES Architects, and EWM leads to rescue go-lives.
If you’re a hiring manager on an S/4 journey, three uncomfortable questions:
Who really owns your plant-floor scope – IT, operations, or your SI?
Do you have a named lead for “plan-to-produce” and “plan-to-ship,” or just a list of PP, QM, and EWM tickets?
Are you hiring module silos, or end-to-end flow owners who can live in the plant for a few months and make decisions?
From a staffing lens, what’s working right now:
Anchor 1–2 senior “floor generals” (PP/MES or PPDS/EWM) who can own design trade-offs with production, quality, and logistics.
Back them with a small squad of doers; local super-user types plus 1–2 strong configurators, not a cast of thousands.
Write job descriptions in plant language (changeovers, downtime, fill rates, compliance) instead of just SAP buzzwords.
The companies that treat plant-floor staffing as a line item under “rollout support” will keep paying for rework after go-live.
The ones that treat PP/MES/QM/EWM/TM staffing as a strategic decision will get stable operations months faster, and with far less noise from the shop floor.
If you’re leading S/4 in manufacturing and want a quick view of what the best-run programs are doing with plant-floor roles, drop a comment or DM “PLANT S4.”

Let’s get specific: the roles your SI keeps under-staffing
PP / PPDS. Not “a PP consultant.” You need someone who has sat with planners, argued about routings, and lived through an MRP run that told the plant to build the wrong thing for three weeks. PPDS is the scarcest skill on this list: heuristics, the optimizer, finite scheduling. Most PPDS resumes have never touched a real production schedule.
MES integration. The handshake between S/4 and the shop floor execution system, whether that is SAP DM, Apriso, Rockwell, or a homegrown MES, is where designs go to die. If nobody owns this interface, it becomes a blame game between your SI, your MES vendor, and your plant engineers. Name one person who owns it. Today.
QM. In aerospace and medical devices, a bad QM design is not scrap. It is a compliance event. Inspection plans, quality holds, batch management, and the integration with production orders: this is where auditors live. Staff it like it matters, because it does.
EWM. Warehouse constraints, labor management, slotting, wave management. Plus one decision most programs sleepwalk into: embedded EWM versus decentralized. That choice has staffing consequences for years. Make it deliberately, with someone who has done both.
TM. Transportation management is the role programs remember in hypercare, when freight settlement is broken and expedite costs are exploding. Hire the TM lead before go-live, not during it.
Three more uncomfortable questions
Who signs off on plant master data, and what happens when two plants define the same material differently?
When a routing changes, is that an IT ticket or a process decision? If you cannot answer in one sentence, your governance is broken.
Has your SI’s PP lead ever walked your shop floor? Not a Teams call. Walked it. If the answer is no, you do not have a manufacturing lead. You have a configuration resource.
What “staffed last” actually costs
A PPDS design fixed in blueprint costs a workshop. The same design fixed after go-live costs a reimplementation, plus expedite freight, plus missed shipments, plus the credibility of your program team with every plant manager in the company. The ratio is not 2x. In our experience it is closer to 10x, and that is before you count the consultants you will hire to fix what the first consultants built.
This is why “rollout support” budgeting is a trap. Support implies the design was right and the plant just needs help using it. When the plant-floor design is wrong, no amount of support fixes it. You are paying for rework disguised as training.
The pattern that works
→ One named owner per end-to-end flow: plan-to-produce, plan-to-ship. Not a RACI matrix. A name.
→ Floor generals on site, in the plant, for months. Design trade-offs get made in the production meeting, not on a status call.
→ Interview loops that include ops leaders. If the plant manager would not trust this person to make a call at 2 AM during month-end close, do not hire them for the plant.
→ Job descriptions in plant language. “Owns plan-to-produce for three plants and 400 work centers” beats “PP consultant with 8 years experience” every time. One attracts owners. The other attracts ticket-takers.
The programs winning right now made one decision early: plant-floor staffing is a strategic bet, not a line item. Everything else, the template, the timeline, the SI, is downstream of that.
