Direct on sale is an Australian online whole sale and retailer. They offer a wide range of products, ranging from clothing, kitchen appliances, bathroom and laundry equipment and even pet care products. Their Ecommerce website also has functionalities such as online shopping, tracking of orders, customer profiling and other customer oriented services. Their aim is to offer the best deals to customers in terms of pricing and excellent quality. A central part of achieving business and general objectives is through meeting requirements of the client (Juristo and Moreno, 2013).
The aim of this study is to establish whether the Direct on sale system was designed as per specifications (version 4.0) and to validate it against system and user requirements.
The method employed in the research process is direct observation. This is one of the most effective methods used in research (Smith, 2015). The researcher used and observed the system to find out the various design aspects. Assisting in the process was the use of a specifications form which depicts features to be checked, their presence, whether they have been validated or not and any comments. The form provides a summary of all design, user and system requirements.

Satisfactory |
As the results indicate, the functional, system and design requirement were excellently met. This shows that the system was implemented very successfully, but with a few areas to be noted. These are outlined in the recommendations below.
The system is excellently designed, developed and implemented, in that, all functional and design requirements are met. However, as regards the graphical user interface, which is quite user friendly, some animations are completely unnecessary. For example, inversely rotating pictures, which confuse the user’s eye, the constantly animated items menu, which don’t give the user a chance to better and thoroughly look into individual items, and finally, the lack of a menu which appropriately prods the user to continue window shopping. It requires a nicely done and noticeable text/graphical menu. In addition, some menu items, such as the user account icon, or shopping cart icon do not contain additional information when a user points at them. Furthermore when a user enters a query in the search engine, other than products, there are no returned information. This needs to be checked.
Conclusion
The design and development of the Direct on sale system has adhered to software engineering standards, which include the meeting of functional and non functional requirements (Bourque and Fairley, 2014). This has resulted in a well designed, fully functional system.
