Thomas asserts that, The main stages in the development of a good interface involves conducting a detailed requirement analysis which aids in establishing the goals to be achieved by the website, outlining the site design and architecture details and performing a task analysis, prototyping, creating, testing and launching the site. After launching the site, analysis of the feedback messages is necessary to improve the site. Dix et al (pg 84) ascertains that, the use of HCI increases the productivity and reduces costs. Saving results due to few errors, reduced user interruption, reduced support staff workload, elimination of maintenance, redesign and training costs.
HCI involves the design, implementation, analysis and evaluation of computer systems in relation to the user, the work and tasks.

HCI design must emphasize on efficient methods of communication between the users. Usability engineering is necessary in the interface design which comprises half of the software work, done on the site. Models must be formulated to help solve solution and allow the designer visualize the situation at hand says, Cooper & Riemann (pg 231). For a successful HCI design, both the user model and the implementation model are important. Most software developers concentrate on the complex software design limiting the functionality and ergonomics of the site from the user's side.

According to Stephen (pg 106), there are two major problems that occur in any network, these problems include not connecting to the right computer and loss of information/ malicious access to information when transferring information from one computer to another in a given network. The SSL system was developed by Netscape and is used for ...Show more
