Reading a 3PL relationship only through a contract and service levels leaves out part of the work. The client follows whether the operation supports commercial goals and customer experience. The service provider turns those expectations into a workable model through process, capacity, resources and risk management. Both sides look at the same flow, but their responsibilities are different.
At Decathlon Türkiye, I worked from the client side. I managed national B2C e-commerce shipping, B2B replenishment for stores, and reverse logistics for store and customer returns. During Black Friday and other peak periods, I coordinated IT, Finance and 3PL teams. I led transport and 3PL tenders for three consecutive cycles and worked on partnership models based on SLAs, incentive and penalty mechanisms, and TCO.
At Arvato, I see the service provider side on the Inditex/Zara operation. I managed outbound together with another Operations Manager and later managed inventory and inbound operations. I set up the outbound plan in a newly opened warehouse and contributed with the team to the operating infrastructure for store and B2C returns. Today, within the Control Tower scope, I follow performance, operational alerts, improvement actions and workforce planning. The expected service has to be considered together with the process and resource plan on the floor.
These two experiences make it harder to assign a problem to one side immediately. A service level deviation may come from process design, a capacity assumption, demand planning, a data definition or a delay in decision making. The first step is to make sure both sides are looking at the same data and using the same definition. Responsibility, action and follow-up date come next.
A healthy 3PL relationship does not mean accepting every client request without discussion or treating every provider constraint as an excuse. The scope of the expectation should be clear. The provider should show the process impact and the risk. The client should share commercial priorities and changing demand in time. This turns a meeting from a review of results into a conversation about how the operation will be run together.
KPI definitions, regular reviews and data from the floor create the common ground. When the client’s service expectation and the provider’s operating reality can be discussed in the same terms, the 3PL relationship becomes easier to manage and more resilient.
