Points of consideration for
interface design
● Clarify the purpose of the data to be
printed and the items included. Next,
clarify what data must be entered for
it to be printed.
● Clarify whether the user of the input
screen or recipient of the form is an
employee or customer, and adjust
the format accordingly.
● Select an appropriate human interface according to user proficiency.
● Select the input/output device according to the contents.
● Minimize the response time and turnaround time, and take steps to ensure that a long time is not spent
waiting for the data to be processed.
● Clarify how to deal with erroneous
operations and system failures.
● Take steps to ensure that the data
entered is not leaked outside the
company.
