STRATEGIES FOR DETERMINING MIS DESIGN

MIS design should be specific to an organization, respecting its age, structure, and operations.

Six strategies for determining MIS design have been suggested by Blumenthal (1969):

  • Organization-chart approach
Using this approach, the MIS is designed based on the traditional functional areas, such as finance, administration, production, R&D and extension. These functional areas define current organizational boundaries and structure.

  • Integrate-later approach

Largely a laissez faire approach, it does not conform to any specified formats as part of an overall design. There is no notion of how the MIS will evolve in the organization. Such an MIS becomes difficult to integrate. In today's environment - where managers demand quick and repeated access to information from across sub-systems - the integrate-later approach is becoming less and less popular.

  • Data-collection approach

This approach involves collection of all data which might be relevant to MIS design. The collected data are then classified. This classification influences the way the data can be exploited usefully at a later stage. The classification therefore needs to be done extremely carefully.

  • Database approach

A large and detailed database is amassed, stored and maintained. The database approach is more and more accepted for two main reasons: first, because of data independence it allows for easier system development, even without attempting a complete MIS; and, second, it provides management with immediate access to information required.

  • Top-down approach

The top-down approach involves defining the information needs for successive layers of management. If information required at the top remains relatively stable in terms of level of detail, content and frequency, the system could fulfil MIS requirements (Zani, 1970). The usefulness of this approach depends on the nature of the organization. It can be suitable for those organizations where there is a difference in the type of information required at the various levels.

  • Total-system approach

In this approach the interrelationships of the basic information are defined prior to implementation. Data collection, storage and processing are designed and done within the framework of the total system. This approach can be successfully implemented in organizations which are developing.

Advantages and Disadvantages of EIS Advantages of EIS Easy for upper-level executives to use, extensive computer experience is not required in operations Provides timely delivery of company summary information Information that is provided is better understood Filters data for management Improves to tracking information Offers efficiency to decision makers Disadvantages of EIS System dependent Limited functionality, by design Information overload for some managers Benefits hard to quantify High implementation costs System may become slow, large, and hard to manage Need good internal processes for data management May lead to less reliable and less secure data

Inter-Organizational Value Chain

The value chain of   a company is part of over all value chain. The over all competitive advantage of an organization is not just dependent on the quality and efficiency of the company and quality of products but also upon the that of its suppliers and wholesalers and retailers it may use. The analysis of overall supply chain is called the value system. Different parts of the value chain 1.  Supplier     2.  Firm       3.   Channel 4 .   Buyer

Big-M Method and Two-Phase Method

Big-M Method The Big-M method of handling instances with artificial  variables is the “commonsense approach”. Essentially, the notion is to make the artificial variables, through their coefficients in the objective function, so costly or unprofitable that any feasible solution to the real problem would be preferred, unless the original instance possessed no feasible solutions at all. But this means that we need to assign, in the objective function, coefficients to the artificial variables that are either very small (maximization problem) or very large (minimization problem); whatever this value,let us call it Big M . In fact, this notion is an old trick in optimization in general; we  simply associate a penalty value with variables that we do not want to be part of an ultimate solution(unless such an outcome is unavoidable). Indeed, the penalty is so costly that unless any of the  respective variables' inclusion is warranted algorithmically, such variables will never be p
