What is a target architecture in logistics IT?

A logistics IT target architecture is a strategic planning document that describes the desired future state of the system-side IT landscape within a logistics organization. It answers fundamental questions: Which systems – such as ERP, WMS, TMS, MFS, or analytics platforms – take on which functional responsibilities? Which systems serve as the leading source for specific data domains? And how do these systems communicate with one another? Unlike a concrete project plan, the target architecture is intentionally technology-agnostic and describes principles rather than individual implementation details.

How does a target architecture work in practice?

A target architecture typically consists of several layers: an overview of the system landscape, a description of data flows and integration points, and a catalog of architecture principles. The latter govern, for example, whether new systems must be connected via standardized APIs, what cloud and on-premises requirements apply, and how legacy applications are to be handled. Particularly relevant for logistics operations is the question of data ownership: which system serves as the authoritative source for product master data, inventory levels, or order information? Establishing this prevents inconsistencies and reduces the effort involved in system integration.

In practice, the target architecture is often developed by an IT architecture function in close collaboration with logistics management. It serves as a guiding framework for all subsequent system decisions – from issuing a tender for a new WMS to onboarding an external logistics service provider. Especially in brownfield projects, i.e., the transformation of existing structures, it provides orientation on which legacy systems should be replaced, retained, or integrated.

• System responsibilities: Which system is the leading source for which data?
• Interface standards: Which protocols and formats are mandatory?
• Operating model: How are interfaces monitored and how are errors handled?
• Cloud strategy: Which systems may or must be operated in the cloud?

What matters when developing a target architecture?

A common challenge is drawing a clear boundary between the strategic target architecture and the operational implementation architecture. The target architecture describes the desired end state; the implementation architecture clarifies how an individual project concretely realizes that end state – with which technologies, configurations, and solution approaches. When the two levels are conflated, the result is either overly abstract documents with no actionable relevance, or overly detailed specifications that constrain every project.

For logistics decision-makers, the vendor lock-in question is particularly central: a well-developed target architecture explicitly formulates requirements for openness and standard interfaces – such as API requirements for WMS or TMS – which can then flow directly into tenders. This transforms the target architecture from an internal planning instrument into a controlling element in the procurement process. Whether best-of-breed or an integrated suite is the right strategic direction depends on the specific business logic and is not a universally applicable standard.
