INTELLIGENCE PHASE : (problem finding, problem formulation)
Information is collected to identify problem.
Various clues are studied related to the problem.
DESIGN PHASE : (development of alternatives).
Analyzing possible courses of action
Understanding of actual problem to generate solutions
CHOICE PHASE:

choice is made and implemented.

A way to do something to get goals...
One cannot perceive (observe) anything that is
not a system in itself.
A system has more than one element/component
Human body is a system with element like organs, tissues,

homeostasis ( the tendency towards a relatively stable
equilibrium between interdependent elements, especially
as maintained by physiological processes.)

to achieve a common objective. These elements
are interrelated & interdependent.

Boundaries/Environment of System
A system is identified by certain limiting factors like
its components

Everything outside the boundaries of a system is
called its environment.

major loss to the organisation.
3.
Data that is not used further should be legally destroyed.
Issuance
Issuance involves the generation of business documents from the data stored as
required by the individuals inside or outside the firm.

ROLL of IT in TPS
Earlier TPS were manual systems.
Clerks used to maintain records or daily transactions manually.
Manual systems present numerous problems that are solvable by the
use of computer or we can say by the use of IT or introducing some
type of information systems. The problems, which can be resolved
with the help of IT, are:
Time Saving
Minimum Error Level
Less Man-power
Storage : Some documents and files in manual system occupy
more physical space and there are chances of lost of data. Computer
provides more compact and secure way to store data.

OFFICE INFORMATION/AUTOMATION SYSTEM (OIS/OAS)
What is office?
An office is a place where staff, secretaries and managers (data
workers) perform administrative and managerial functions.
Every organisation has an office. All management's and
administrative task are performed in the office.
Office Automation : Movement towards automation of office
task.
Office automation is the application of computer and related technologies
like communications and networking to integrate the general task of an office
so that the efficiency of office work improved.

Although all the work of a small or big organization can be done manually,
but it is very difficult or even impossible today to compete in the market
without OA. WE need OA because:
•
•

•
To reduce the cost of administrative overheads
To increase the efficiency of office tasks
To provide better services to customers
To provide accurate information to Management.
To provide fastest and best way of communications.

OBJECTIVES OF DSS
It should assist managers in making decision to solve their semistructural problems.
It should support manager’s judgments rather that replace it.
It should improve effectiveness of decision rather than efficiency.
Technically , a DSS may not involve high technology, but the right use of
technology/tools is important. They should also be flexible and easy to use.
Since purpose of this system is to provide support, hence they are called

In the case when there are many condition the decision
trees become very complicated. In this case decision
tables are created.
Decision table is a matrix of rows and that shows conditions and
actions.
It is used for more complex circumstances where several

The requirement analysis is a means of translating the
ideas given by the users into a format document called
SRS
A good SRS provides the following benefits:
• Bridges the communication gap between the user and
developer by acting as a basis of an agreement between
the two parties.
•Reduces the development cost by overcoming errors
and misunderstandings in the development.

Por t abl e: Should be independent of Hardware and software. I n future user may
change its technological platform.

Easy t o use: A good design is assessed by the ease with which it is learnt and
operated by the staff and the managers. The design should be user centered.

Waterfall Model ( Limitations)
•Model assumes that the requirements of a system can be
frozen before the start of designing. But for a new system,
determine the requirements is a difficult process as user
himself does not know his information requirements.
•Freezing the requirements usually requires the choice of
hardware to be made. In large projects, which takes few
years to be completed, the earmarked hardware
technology may become obsolete even before the system
become physical.
•Model Stresses that the requirements should be
completely specified before the next phase. But in some
cases we have to develop a part of whole system and
later enhance the system in phases
