Wolfgang Hartwig

When supply chain, logistics, or 3PL management become critical issues, I bring structure to the situation.

Wolfgang Hartwig

Mission

I help companies when their delivery capacity, inventory, SAP processes, or external logistics providers can no longer be reliably managed—by providing rapid analysis, clear prioritization, and robust implementation.

Vision

As an interim manager, I work at the intersection of operations, logistics, SAP, IT, service providers, and management. My goal is to restore transparency, decision-making capacity, and control in critical situations.

Current term of office runs through the end of September 2026.
New client inquiries can be scheduled starting in October 2026.

When companies call me.

Availability

Delivery capacity is at risk or can no longer be managed in a transparent manner.

Inventory

Inventory levels across SAP, the plant, the warehouse, and the logistics service provider do not reliably match.

Not stable

A 3PL outsourcing arrangement is not stable from an operational, organizational, or systemic perspective.

Daily Errors

Inbound, outbound, goods receipt, goods issue, and posting processes lead to errors on a daily basis.

Incorrect Procedures

SAP ECC, S/4HANA, interfaces, and operational processes do not integrate seamlessly.

Working Side by Side

Departments, IT, and external service providers work alongside one another rather than with one another.

Clear Priorities

Backlogs, error lists, and escalations are piling up without any clear priorities emerging.

Controllability

Executive management, the COO, or supply chain leadership need to quickly regain transparency and control.

Wolfgang Hartwig

My typical areas of expertise

My work focuses on supply chain stabilization, logistics and 3PL management, SAP-related operational processes, as well as transformation and outsourcing.

Supply Chain Stabilization

I bring transparency, prioritization, and a drive to get things done to critical supply chain situations—especially when delivery capacity, inventory, or operational processes are at risk.

Logistics & 3PL Management

I provide support in managing external logistics service providers, handling escalations, SLA issues, inventory discrepancies, process disruptions, and coordination between the client, the warehouse, transportation, and IT.

SAP-Related Operational Processes

My focus is on the connection between operational reality and SAP processes: inbound, outbound, inventory, goods receipt, goods issue, interfaces, posting logic, ECC, and S/4HANA.

References & Impact

What stood out was the speed with which Mr. Hartwig familiarized himself with the challenging topics surrounding the complex global supply chain. In an environment that, at the start of the project, was characterized by the complete restructuring of a department, poorly structured (IT) processes and tools, yet simultaneously demanded a high degree of responsibility, Mr. Hartwig provided the support we had hoped for from day one. Ultimately, he was the key to ensuring that the transformation project was carried out successfully. After six months, Mr. Hartwig is handing over a fully functional team that is so well-structured that new team members can quickly familiarize themselves with the processes.

General Manager

During his 18-month tenure as an interim manager at our production site part of an international construction equipment group, Mr. Hartwig delivered outstanding results. With a high level of professional expertise and strong leadership skills, he managed five departments with a total of 60 employees and successfully oversaw the restructuring of the organization. By appointing new team leaders and strategically optimizing the logistics structure, he was able to achieve significant efficiency gains. Particularly noteworthy are the drastic reduction in inventory levels of purchased components—amounting to tens of millions—as well as the significant cost reductions achieved with external service providers and in shipping processes.
