Interfaces: 30 projects with declining demand in the IT market
Interfaces are technical connections between different systems that enable data exchange and communication. They are used in integration technology to link various applications, databases, or external services with one another. Within the context of SAP and other ERP systems, interfaces play a central role, as they allow organizations to unify their diverse IT landscapes. Interface Development as a specialized discipline focuses on the design and implementation of such connections.
Organizations seek professionals with interfaces expertise primarily for integration projects where multiple systems must be brought together. Typical tasks include analyzing requirements, designing data exchange processes, and implementing APIs or other integration solutions. Such projects often arise during system migrations, when introducing new ERP systems, or when organizations modernize their existing systems. Freelancers are frequently engaged for time-limited phases in which specific technical knowledge is required.

Methodology: We count IT postings of the last 90 days that mention Interfaces. Projects posted several times that are detected as duplicates count once; postings without an assignable IT category are missing, so the figures are a lower bound. The trend compares the share of all IT postings with the 90 days before and only appears with enough comparison data. We do not show figures based on fewer than 30 data points. Distributions only refer to postings that state the respective attribute; we state the coverage alongside. The description of the skill is created automatically (from our skill directory or by AI) and checked by machine: no numbers, no company names, only the skill and its neighbours in the taxonomy. Texts are created and checked automatically, numbers come from the postings.
