Question 1: Chapter 8 – User Interface Design [21 Marks]
1.1 Effective, Reliable, and Maintainable Systems (9 Marks)
In user interface design and systems analysis, the quality and long-term functionality of
a system depend significantly on three core attributes: effectiveness, reliability, and
maintainability. These attributes ensure that the system meets user needs while also
remaining operable and adaptable over time.
Effective Systems
An effective system is one that performs its intended tasks in a way that fully satisfies
user requirements. It allows users to achieve their goals with precision, minimal effort,
and satisfaction. Effectiveness emphasizes task completion, usability, and functional
correctness.
For example, a well-designed hospital management system allows staff to admit
patients, update medical records, and retrieve diagnostic information quickly and
without error. The interface must provide appropriate feedback, validate input, and align
with user workflows to ensure effectiveness. An effective system also supports
accessibility, enabling users with diverse needs to interact with the system with ease.
Reliable Systems
Reliability refers to the system’s ability to perform consistently under predefined
conditions. A reliable system is free from bugs and is capable of error-free operation
