01 Less day-to-day management
Within the agreed scope, we handle team organisation, deployment planning and daily coordination. Your managers gain time for the tasks that move your business forward.
Blue Collar
Outsourcing
Your processes. Our responsibility.
Orders grow, workloads fluctuate and skilled workers are hard to find. At the same time, goods need to be dispatched on schedule, components assembled accurately and technical services delivered reliably. That takes well-coordinated teams and effective day-to-day management.
With Blue Collar Outsourcing, Trenkwalder takes over clearly defined operational areas in field service, logistics and assembly. We organise the teams, manage the processes and take responsibility for the agreed delivery – through a tailored works or services contract.
For you, that means less time spent on workforce organisation and coordination, transparent service delivery and more room to focus on your core business.

Frequently asked question
Blue Collar Outsourcing means transferring clearly defined manual, technical or industrial activities to an external partner. At Trenkwalder, this primarily covers field service, logistics and assembly. We take responsibility for the agreed services, including team organisation and operational management.
Examples include technical installation and maintenance, order picking, packaging, defined warehouse processes, pre-assembly, rework and associated quality checks. The activities we take over are determined by your processes and requirements.
No. Individual, clearly separable processes can also be outsourced. Together, we define the right scope and the handover points with your internal teams.
You reduce the internal workload associated with workforce organisation, team leadership and daily coordination in the outsourced area. Defined services, quality criteria and billing units also provide greater transparency over results and costs.
You reduce the internal workload associated with workforce organisation, team leadership and daily coordination in the outsourced area. Defined services, quality criteria and billing units also provide greater transparency over results and costs.
Yes. Alongside long-term arrangements, the model can cover time-limited projects or seasonal requirements. The scope must be clearly defined and suitable for operational transfer.
We take your current workflows and systems into account when designing the solution. Together, we agree the interfaces, access requirements and information flows needed for delivery, including how handovers will work.
Before launch, we agree suitable metrics and inspection criteria. These may include volumes processed, error rates, on-time delivery or documented quality checks. Results are reviewed regularly and discussed with you.
Trenkwalder organises and leads its own teams within the agreed scope. Onboarding, required training, safety measures and equipment are organised according to the tasks and the responsibilities set out in the contract.
With Blue Collar Outsourcing, you commission a defined service that Trenkwalder delivers through its own teams and operational management. With temporary employment, agency workers join your team and work under your operational direction. Together, we determine which model best meets your needs.
We begin by analysing your requirements and the processes to be outsourced. We then define the scope, interfaces, quality targets and pricing. Based on this, we prepare teams and workflows and agree the operational launch with you.
