The success of the system depends on the depth of difficulty that is faced by users to study and use the system. Learning is a complex process, thus a good system needs to help users in the process of learning. It is normally assumed that users are able to learn everything from documentations and guidance books. But, in reality, not many users refer to these guide books or documents. Give the problems in a research findings of Mack.et.al (1984) about the problems faced by users in the process of learning a new system.

There are a number of SDLC models produced based on the user-centred design approach. Give three of these approaches.
When designing a system to support group communication in an organisation, there is a number of issues that need to be taken into consideration. Present these considerations in the light of good HCI system development practice.
