3.  Day to day business transactions
 Make structured decisions
 Defined rules that guides them while making
decisions
 For example, if a store sells items on credit
and they have a credit policy that has some
set limit on the borrowing. All the sales
person needs to decide whether to give
credit to a customer or not is based on the
current credit information from the system.

4.  Organization level is dominated by middle-level
managers, heads of departments, supervisors,
etc.
 Tactical users make semi-structured decisions
 As an example, a tactical manager can check the
credit limit and payments history of a customer
and decide to make an exception to raise the
credit limit for a particular customer. The
decision is partly structured in the sense that the
tactical manager has to use existing information
to identify a payments history that benefits the
organization and an allowed increase
percentage.

5.  Senior level in an organization
 The users at this level make unstructured
decisions
 long-term planning of the organization
 use information from tactical managers and
external data to guide them when making
unstructured decisions.

6.  a set of things working together as parts of a
mechanism or an interconnecting network; a
complex whole

7.  A system has three basic elements input,
processing and output. The other elements
include control, feedback, boundaries,
environment and interfaces.

8.  Input is what data the system receives to
produce a certain output.
 What goes out from the system after
being processed is known as Output.

9.  The process involved to transform input into
output is known as Processing.
 In order to get the desired results it is
essential to monitor and control the input,
Processing and the output of the system. This
job is done by the control.

10.  The Output is checked with the desired
standards of the output set and the
necessary steps are taken for achieving the
output as per the standards, this process is
called as Feedback.
 The boundaries are nothing but the limit
of the system. Setting up boundaries
helps for better concentration of the
actives carried in the system.

11.  The Output is checked with the desired
standards of the output set and the
necessary steps are taken for achieving the
output as per the standards, this process is
called as Feedback.
 The boundaries are nothing but the limit
of the system. Setting up boundaries
helps for better concentration of the
actives carried in the system.

12.  The things outside the boundary of the
system are known as environment. Change in
the environment affects the working of the
system.
 The interconnections and the interactions
between the sub-systems is known as the
Interfaces. They may be inputs and
outputs of the systems.
