Explain the relationship between supply and demand. Solution The law of demand states that as the price of the product increases/decreases the demand of the product falls/rises respectively. Also, the lasw of supply states that as the price increases the supply of the product increases since sellers are more willing to sell their products at higher prices. Now , the realtionship between supply and demand can be studied by looking at the price movement. As the price goes up, the suppy goes up and the demand falls. So, as supply rises more than the required amount of goods, the demand falls and as the supply falls, the demand of the good increase as the price also falls along with the fall un supply..

1. Explain the relationship between system implementation and a systems development life cycle
(SDLC).
Solution
System implementation represents a stage or phase in a fuller cycle of systems development.
This can be viewed as a serial process, whereby each stage produces an output which in turn
becomes the input for the next stage forming a systems development life cycle (SDLC). Some
models depict the SDLC in terms of five stages (analysis, design, implementation, testing and
evaluation). The SDLC is a process of creating or altering information systems, and involves the
participation of users and managers throughout.
The implementation stage of the SDLC is initiated after the system has been accepted by users.
This phase continues until the system is operating in accordance with the previously defined user
requirements and includes data transfer, on-going staff training and minor changes to perfect the
system. While all of the planning stages that take place in preparation for the implementation
phase are vitally important, successful implementation is critical.
