Solving Problems Using IT
Computers are used in all areas of business, industry, government, education, transport, medicine, everywhere. Each one of these applications arose as someone’s solution to a problem.
Solving a problem may be seen as a number of main stages. In producing a solution, a new information system is developed.
The sequence of steps in developing a new system to solve a problem is called the system life cycle.
A systems analyst analyses existing systems and develops new ones.
The main steps in the system life cycle are:
Problem Recognition establishes what exactly the problem is. It is a preliminary study of the situation
You would study the following;
A feasibility study establishes whether or not a new system is a good idea, and estimates the time and resources required to develop it.
Management has to approve the feasibility report before the project can go ahead.
Once permission to go ahead an analysis is done to:
different possible solutions are considered;
Construction of the new system includes:
Software and hardware needs to be installed
Files need to be converted
Conversion can be carried out as:
System maintenance and review
