The Analyst as a Business Problem Solver
System analysis and design focuses on understanding the business problem and underlining the approach to be taken to solve it.
The challenge of the analyst is to select the best solution with the fewest risks and most benefits.
A system analyst can best be described as someone who uses information technology to solve business problems.
A typical decision process followed is outlined below…
Systems that Solve Business Problems
One can divide a system into many subsystems, which in return can be further divided into subsystems. This approach of dividing a system into components is referred to as functional decomposition.
Every system has a boundary between it and its environment. Any inputs and outputs must cross the system boundary.
In my experience it has been at the system boundary where the most challenges occur in system development
The automation boundary is the boundary between automated systems and humans. On one side of the boundary are the humans, on the other side are the other systems.
