CH-01
Broken delivery promises
ATP logic is fragmented across plants and systems, so order confirmations cannot be trusted. Escalations rise, and revenue sits at risk against dates nobody believes. A unified availability architecture is the fix.
Independent architecture advisory · SAP S/4HANA
S/4HANA programs fail in design, not in build.
ZYNARC designs the supply chain and agentic AI architecture that transformation programs are built from — the blueprint, the decision architecture, and the governance that determine whether the program lands. Principal-led, and independent of implementation revenue.

What brings clients here
Five problems that architecture solves and delivery cannot.
These are the conditions CIOs, VPs of Supply Chain, and SAP program directors describe on the first call. Each traces back to a design decision made too late, or made by a team without an enterprise view.
CH-02
Supply allocation chaos
Under constrained supply — routine in semiconductor, pharma, and medical devices — allocation becomes ad hoc and favours whoever escalates loudest. Product allocation architecture replaces that with policy.
CH-03
Transformation risk
Critical architecture decisions get deferred, or delegated to implementation teams without an enterprise perspective. The gaps surface during build, as rework. This is the failure mode ZYNARC exists to prevent.
CH-04
Planning and execution disconnect
Plans built in IBP are not reliably reflected in S/4HANA execution. Inventory drifts out of alignment, service levels slip, and planners spend the quarter firefighting instead of planning.
CH-05
Agents your landscape cannot run
Standard SAP agents reason over standard processes and data. Heavily modified landscapes, fragmented master data, and BAPI-bypassing integrations block activation entirely — a clean-core problem wearing an AI label.
Recognise two or more of these?
That is usually the point at which an independent architecture review pays for itself several times over.
Start the conversation →The agentic shift
Agents do not fix a broken architecture. They inherit it.
SAP Joule has moved from copilot to agentic platform — dozens of specialised agents, thousands of skills, and multi-agent coordination across SAP and non-SAP systems. Agents now plan, decide, and act inside core processes rather than waiting to be asked.
That changes what architecture has to account for. An agent reconfirming an order or reprioritising allocation is touching a revenue commitment. The question is no longer whether the agent works. It is what the agent is permitted to decide, on what data, under whose authority, with what audit trail.
The prerequisite for agentic supply chain is not an AI strategy. It is a clean core, a governed master data model, and an explicit decision-authority architecture.
-
Agentic readiness assessment
Clean-core posture, master data quality, custom-code debt, and BTP configuration — scored, with a verdict on which agents your landscape can actually support today and what stands in the way of the rest.
-
Decision-authority architecture
What an agent may decide autonomously, what it recommends, and what escalates to a human. Defined per process, with thresholds, and traceable to the commercial risk each decision carries.
-
Agentic fulfilment and aATP design
Where agentic AI meets the hardest part of supply chain. Backorder resolution, allocation reprioritisation, and delivery reconfirmation need PAL, BOP, and RfD architecture underneath them before an agent touches them.
-
Multi-agent orchestration boundaries
Disruption signals propagating from supply chain into planning and finance need designed handoffs and containment. Emergent coordination is a risk posture, not an architecture.
-
Agent governance framework
Guardrails, human-in-the-loop checkpoints, and audit evidence built for regulated environments — pharma, medical device, and semiconductor validation obligations do not pause for autonomy.
Service portfolio
Six architecture practices. All advisory, all principal-led.
ZYNARC defines the design. Implementation partners execute within the blueprint. Engagements are scoped as fixed-fee advisory against named deliverables, or as monthly architecture oversight during program execution.
SV-01
S/4HANA Supply Chain Transformation ArchitectureFlagship · 8–16 weeks
End-to-end supply chain architecture blueprints for organisations moving from SAP ECC or non-SAP ERP to S/4HANA. Covers planning, order management, inventory, warehousing, and transportation as one connected design — plus the phased roadmap and governance framework that carry it through execution.
SV-02
Agentic AI & Autonomous Supply Chain ArchitectureNew · 4–12 weeks
Readiness assessment, decision-authority design, orchestration boundaries, and the governance framework that makes agentic operations auditable. Built for supply chain specifically, where agent decisions carry delivery commitments and revenue consequences.
SV-03
Global Availability & Allocation ArchitectureaATP · 6–12 weeks
Deep architecture advisory for Advanced Available-to-Promise — the most technically complex and commercially exposed component in an S/4HANA supply chain program. For organisations running constrained supply, global customer networks, and real prioritisation stakes.
SV-04
Advanced Product Configuration ArchitectureAVC · 6–12 weeks
Variant and configuration architecture for configure-to-order and engineer-to-order portfolios. Product structure, characteristics and dependency design, downstream integration into pricing and fulfilment, and LO-VC to AVC migration architecture.
SV-05
Supply Chain Planning ArchitectureIBP · 6–12 weeks
Demand, supply, inventory, and S&OP architecture — and critically, the planning-to-execution integration that decides whether a plan survives contact with S/4HANA. Includes migration architecture from APO and legacy planning platforms.
SV-06
Global Order-to-Cash ArchitectureOTC · 6–14 weeks
The most cross-functional process in the enterprise: order management, pricing and condition technique, credit, contracts and rebates, delivery, billing, returns, and revenue recognition. Poor OTC architecture shows up as revenue leakage and billing delay long before anyone calls it an architecture problem.
ZTAM · ZYNARC Transformation Architecture Method
Every engagement runs the same method.
ZTAM is the structured approach applied across all client work. It is what separates architecture advisory from ad-hoc consulting: a defined method, traceable decisions, and deliverables an implementation partner can build against without interpretation.

What you own at the end
Architecture artefacts, not a slide deck.
Every engagement closes with formal deliverables the client retains in full — the reference design that governs the program long after ZYNARC's direct involvement ends.

These deliverables become the reference design.
ZYNARC does not present findings and walk away. Implementation partners receive the artefacts as the authoritative blueprint they are required to build from — and the client owns them outright.
Competitive position
Why an independent architect, and not the firm already on the program.
Buyers evaluating SAP transformation partners meet a consistent gap. Large integrators bring scale but dilute architecture under delivery pressure. Module specialists bring technical knowledge without enterprise design. ZYNARC occupies the layer neither of them owns.
| Alternative | Structural weakness | ZYNARC position |
|---|---|---|
| Tier-1 integrators | Implementation-led; architecture diluted by delivery pressure and junior-heavy staffing. | Advisory only. No implementation revenue means no incentive to shape the design around a delivery model. |
| SAP consultancies | Module-level expertise applied generally; architecture is not the primary differentiator. | End-to-end supply chain architecture spanning aATP, AVC, IBP, OTC, EWM, and TM as one integrated design. |
| Independent contractors | Narrow scope, no structured method, no repeatable IP or formal deliverable set. | ZTAM method, defined architecture artefacts, and enterprise-scale transformation design experience. |
| Internal SAP teams | Rarely carry aATP, AVC, or agentic depth; constrained by bandwidth and internal politics mid-program. | Independent perspective with specialist depth in the domains that decide program outcomes. |

Founder & Principal Architect
Twenty years of SAP enterprise architecture and supply chain transformation leadership, concentrated in the areas where programs are hardest to get right: S/4HANA transformation architecture, advanced availability and allocation, order-to-cash, and advanced variant configuration.
ZYNARC was founded on a specific observation from those programs. The decisions that determine whether a transformation succeeds are made in the first weeks, by whoever is in the room — and on most mid-market programs, nobody in that room is accountable for architecture. ZYNARC is the answer to that gap.
Every engagement is led personally. Clients get the architect, not an account team routing work to a delivery pyramid.
Start here
A 45-minute call is usually enough to see the gap.
Bring the program you are planning or the one already in flight. We will walk the architecture, name the decisions still open, and tell you plainly whether an independent architect is worth your budget.
