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

CONCEPTUAL VIEW OF MIS

The concept is a blend of principles, theories and practices of management, information and system giving rise to a single product called MANAGEMENT INFORMATION SYSTEM . The concept of management gives high regard to the individual and his ability to use the information. MIS gives information through data analysis. While analyzing the information, it relies on many academic disciplines like management science, OR, organization behavior, psychology, etc. The foundation of MIS is the principles of management and its practices. MIS uses the concept of management control in its design and relies heavily on the fact that the decision maker is a human being and is a human processor of information. A MIS can be evolved for a specific objective it is evolved after systematic planning and design. It calls for an analysis of business, management views and policies, organization culture and the management style. The MIS,therefore relies heavily on systems theory.The systems theory offers soluti
