2. What is system approach ?
A system approach
Is an old concept. The approach stands on the
Assumption that breaking down of a complex concept
Into simple easy to understand units helps in better
Understanding the complexity within any organization.

9. Deterministic system :-
A system is
deterministic if its outputs are certain. This
means that the relationships between its
component are fully known and certain. Hence
when input is given output is fully predictable.
Probalistc System:-
A probalistc system is
one where the output from the system behaves
probalistcally. The output is predictable
according to probablity values.
10. Random system :-
Random system are completely
unpredictable systems. One is completely
unaware
of the components and their relationships with
each other and hence, the output is random. An
example of random system is the transport system.
Human system :-
A human system consists of
humans as components. It is an open system
exhibiting probabilistic behaviour. An example of
this kind of system is a department within an
organization.
11. Machine system :-
A machine system is composed of
entirely of machines and machine subsystems. It is
deterministic and relatively closed. An example of this
type of system would be a fire alarm system.
Adaptive and non adaptive system :-
A system is said to be adaptive if it
Modifies itself with the changes in its environment. A
democratic system of government is an example of
adaptive system.
A non adaptive system does not
react to changes in its environment.
12. Defining the problem :-
This is the step
When the problem has to be defined.
This is the initial stage of problem solving.
13. Developing alternative solutions :-
this is
the logical next step in the systems
approach for problem solving. In this stage
alternative solutions are generated.
Selecting a solution :-
in this step, the
Solution that suits the requirement and
objectives in the most comprehensive
Manner is selected as the best solution.
14. Designing the solution :-
once the most
appropriate solution is chosen, it is then
Made into a design document . At this stage
the details of the solutions are worked out to
create the blueprint for the solution.
Implementing the solution :-
it is next step in the
process. The solution that has been designed is
implemented as per the specification laid down
in the design document.
15. Reviewing the solution :-
this is the final
step in the problem solving process where
the review of the impact of the solution is
noted. This is a stage for finding out if the
desired result has been achieved that was
Set out.
