What is Information System?
  •Individuals - Entertainment and enlightenment
  •Businesses - Decision making, problem solving and control
  •Information Systems (IS) refers to the interaction between
  processes and technology
  •Information Systems is Organized collections of hardware,
  software, supplies, policies, procedures and people, which
  store, process and provide access to information.
                                                                3
   Introduction to Management Information Systems [1]
What is Management Information System?
 (MIS) are designed to provide past, present, and future routine
information appropriate for planning, organizing, and controlling the
operations of a functional area in an organization
 A manual or computerized system that collects, processes, and reports
data needed to manage a planning delivery system.
 An 'MIS' is a planned system of the collecting, processing, storing and
disseminating data in the form of information needed to carry out the
functions of management

        Objectives of the MIS
MIS - capabilities
The term 'information system' is a general term for
 a system that facilitates access to information
Reach an understanding of the relevant processes
on the basis of the available historic information. This element forms the basis
for the development of models, required for forecasting and simulation.
Provide information on the current situation, especially for early warning
purposes, for instance related to issues impacting on food security, water
resources or pest and disease status.
Forecast changes and impacts, either natural or man-made , as an element in
vulnerability assessments.
Forecast the consequences of policy decisions and measures before they
are implemented in reality. This implies evaluating options for several given
scenarios based on the possible results and predicted consequences, and
selecting the most acceptable alternative.                                  14

    What is Information Systems?
•   Information Systems (IS) are more than computer hardware and
    software.
•   It is not just developing business applications programs
•   Information Systems include:
      – Information Technology
      – Management
      – Organization
•   Ultimately, IS are used as strategic tool to improve an organization’s
    competitive advantage.

• Information Systems Careers
   –   Systems analyst, specialist in enterprise resource planning (ERP), database administrator,
       telecommunications specialist, consulting, etc.
• Knowledge Workers
   –   Managers and non-managers
   –   Employers seek computer-literate professionals who know how to use information technology.
• Computer Literacy Replacing Traditional Literacy
   – Key to full participation in western society

       Ethical and Societal Issues

• Consumer Privacy
   – Organizations collect (and sometimes sell) huge amounts of data
     on individuals.
• Employee Privacy
   – IT supports remote monitoring of employees, violating privacy
     and creating stress.
                                                                     30
                     Business Model [6]
A business model describes the rationale of how an organisation creates, delivers, and
captures value - economic, social, or other forms of value. The term business model is
thus used for a broad range of informal and formal descriptions to represent core
aspects of a business, including purpose, offerings, strategies, infrastructure,
organisational structures, trading practices, and operational processes and policies.

•   The Four Stages of Data Processing
    – Input: Data is collected and entered into computer.
    – Data processing: Data is manipulated into information using
      mathematical, statistical, and other tools.
    – Output: Information is displayed or presented.
    – Storage: Data and information are maintained for later use.

Information System Architecture
An information system architecture is a formal definition of the business
processes and rules, systems structure, technical framework, and product
technologies for a business or organizational information system.
An information system architecture usually consists of four layers: business
process architecture, systems architecture, technical architecture, and
product delivery architecture.
The architecture of an information system encompasses the hardware and
software used to deliver the solution to the final consumer of services. The
architecture is a description of the design and contents of a computerized
system. If documented, the architecture may include information such as a
detailed inventory of current hardware, software and networking capabilities; a
description of long-range plans and priorities for future purchases, and a plan
for upgrading and/or replacing dated equipment and software. The
architecture should document: What data is stored?, How does the system
function?, Where are components located?, When do activities and events
occur in the system?, and Why does the system exist?
                                                                                  36

A business architecture is an

Business architecture is closely related
  to practice of enterprise

2. Systems architecture
An architecture description is a formal
   description of a system, organized
   in a way that supports reasoning
   about the structural properties of
   the system.
It defines the system components or
    building blocks and provides a plan
    from which products can be
    procured, and systems developed,
    that will work together to
    implement the overall system. This
    may enable one to manage
    investment in a way that meets
    business needs.                       40

It describes the structure and
    behaviour of the
    technology infrastructure
