4.1 Understand user interface design
Evolution of the User Interface
the user interface mainly consisted of process-control screens that allowed the user to send commands to the system
That approach worked well with traditional systems that simply transformed input data into structured output.
As information management evolved from centralized data processing to dynamic, enterprise-wide systems, the primary focus also shifted — from the IT department to the users themselves
User-centered system
