1- Bits n’ Pieces limited is a company that sells consumer electronics. The company has
sales personnel operating in major towns in Kenya. Until now, whenever a sales person
wants to make an inquiry about availability of stock or to find the detailed specification
of a product, they have to make a telephone call to the head office so that the products
can be searched and information relayed over the phone. This causes delays for sales
people when they have many responses to deal with. Additionally, the sales people would
like to make decisions about the stock items that should be reordered, and also to make
projections of anticipated sales from marketing campaigns that they carry out so as to try
and meet sales targets while staying within budget. The sales people on the ground would
thus like to interact with the head office databases directly and require both software and
hardware to enable this. The IT department wants to set up an automated system that will
allow sales people to carry out their inquiry and analysis activities. This project will be
rolled out to all sales people scattered country wide. You have been asked to recommend
