In systems integration, which of the following is NOT typically a responsibility of non-developers?

The role of non-developers in systems integration primarily involves activities that do not require deep technical coding skills. Among the choices presented, writing integration code is clearly a responsibility that falls under the domain of developers, as it demands programming knowledge and experience in software development.

Non-developers typically engage in defining data mapping requirements, preparing screen mock-ups, and assisting with documenting integration requirements, as these tasks focus on understanding business needs, user experience, and ensuring that technical specifications align with organizational goals. Tasks like defining data mapping and preparing screen mock-ups are crucial for ensuring that the integration meets user needs without needing to delve into the underlying code. Hence, writing integration code stands apart as a specialized skill, making it the option that does not align with the typical responsibilities of non-developers in the integration process.
