Different jobs, system analysis, human computer interaction, HCI, task analysis
Generally, task analysis involves the study of how people perform their different jobs with the objective of determining what it is that they do, the things that they use and suggesting what they must know. According to Chen (2001), in Human-Computer Interactions (HCI), the process of task analysis verifies the specific actions that a user must undertake so as to attain their objective of accomplishing a given task. In specific, the analysis of task directly describes the procedure that the user must actually employ. As such, task analysis helps in predicting the ease with which users can learn new tasks so as to become a proficient user of a particular software, application or machine. Further, Chen (2001) asserts that task analysis provides evidence of how an interface is good at offering support for exploration and also the time an expert would take to execute a given task. Hence, the ignorance of task analysis may lead to a biased application in which the maker emphasizes on one of the interfaces or does not realize the differences in the two interfaces of HCI.

[...] The use of information access interfaces allows various mechanisms for reducing the memory load that can also be used for determining the efficiencies of the system (Shelly & Rosenblatt, 2010). For instance, in the search process, the interfaces of HCI design should allow users to return to strategies that had been abandoned temporarily, jump from one strategy to another and retain information throughout the sessions of search. Thirdly, the HCI interface should provide alternatives for expert and novice users. This principle examines how an interface balances the simplicity of use of an interface against the power to perform various tasks. [...]

[...] However, this approach is challenged by the current increasing diversity of the users, the types of technology and the various contexts in which interface design is applied. Further, this user-based approach for interface development does not encompass the user fully (Coutaz &Calvary, 2012). For instance, the measure does not take into account or reflect the emotions of the user. As such, HCI has broadened beyond this measure and, therefore, the design should consider the emotional appeal as an effectiveness measure of the design. [...]
