About MISy A management information system is a system that

  provides information needed to manage organizations

effectively.

y In other words a computer system design to help managers

 plan and direct business and organizational operations.

y The design and implementation of an MIS cannot be carried

out in an unplanned fashion. The different groups of tasks andthe cost of design and implementation make it a major project.

y The conceptual design outlines the structure of the MIS andindicates the performance requirements for those who willdevelop the detailed design.

y The managers who are going to make use of it should have a

major role in the development and evaluation of alternativeconcepts

.

y The management must recognize the fundamental business problems and objectives of the MIS.

y The system constraints can be environmental, basic

  business, or technical. The management is mainly

responsible for describing this.

y The detailed design starts with the performance

specifications provided by the conceptual design and ends

with a set of specifications for the construction of the

MIS.

y If the operating system is not going to be changed, the

design of the MIS should be developed in association with

the design of the operating system.

y A complete description of the detailed design cannot be

given, as design work is a creative and problem-solving

activity.

y The 'systems approachµ to problem solving uses a systems

orientation to define problems and opportunities and

develop solutions.

Design process alternativesy Analysis of design process alternatives requires the

options to be carefully understood and described.

y A method for evaluation of design process alternatives has been applied to development projects at VAC.

y Analyzing design process of Volvo aero corporation is

done by using signal flow graphs.

y Signal flow graphs consist of preliminary design, test andevaluation method, detail design is processed and after 

that this method is repeatedly used.

yThe signal flow graph is well known as a

method for circuit and systems analysis in

electrical engineering and for modeling

discrete-event systems.

yThe edibility and quality of product

development processes can be evaluated bymodeling various features of the design

 process.

yComputational methods, such as finite element

analysis and computational fluid dynamics

(CFD) are increasingly used to perform these

  predictions of product behavior during

development.yHowever, these new design methods and

strategies affect the flow and timing of 

activities within the product development process.

Online processingy In this processing, transaction can be keyed in at

terminals at remote sites and transferred to computer

system via telecommunications channels.y Online order system is an example of online

processing

y There are two types of online processing are:

online with batch overnight update.online intermediate update.

Distributed data processingy In this processing, local transaction can be used to

update local files and summary results can be

transmitted to central system.y It is mainly used by stores such as sears and J. C.

Penney are the good example of this approach.

y In this system sales transactions updated local

inventory database.

Decentralized processingy A dedicated minicomputer or microcomputer with its

own database can serve as a decentralized system.

y A local word processing system in an office and adedicated and production planning system in a plantare good examples of decentralized processing.
