What is the systems development technique that produces a graphical representation of a concept or process?

Modeling is the correct answer because it specifically refers to creating a visual or graphical representation of a concept, system, or process. This technique is commonly used in systems analysis to help stakeholders understand and visualize the requirements and architecture of a system. It allows analysts and designers to depict relationships, processes, and structures in a format that is clearer and often easier to comprehend than textual descriptions.

In systems development, models can take many forms such as flowcharts, data flow diagrams, UML diagrams, and more. These visual tools not only facilitate communication among team members but also help in identifying potential issues in system designs, ensuring that all requirements are considered and understood.

While prototyping involves creating a functional version of a system to gather user feedback and refine requirements, and scripting pertains to writing code for automation or other functionalities, neither of these techniques is primarily focused on producing graphical representations. Mapping can be used in certain contexts but is often more specific to geospatial or data context than the broader application of modeling in systems analysis.
