ALTMAN, EDWARD developed the "ALTMAN Z-SCORE" by examining 85 manufacturing companies. Later, additional "Z-Scores" were developed for private manufacturing companies (Z-Score - Model A) and another for general/service firms (Z-Score - Model B). VentureLine selects the "Z-Score" appropriate for each firm based upon the questionnaire input from the listing company. A "Z-Score" is only as valid as the data from which it was derived i.e. if a company has altered or falsified their financial records/books, a "Z-Score" derived from those "cooked books" is of highly suspect value.
VALUE CHAIN is the sequential set of primary and support activities that an enterprise performs to turn inputs into value-added outputs for its external customers. As developed by Michael E. Porter, it is a connected series of organizations, resources, and knowledge streams involved in the creation and delivery of value to end customers. Value systems integrate supply chain activities, from determination of customer needs through product/service development, production/operations and distribution, including (as appropriate) first-, second-, and third-tier suppliers. The objective of value systems is to position organizations in the supply chain to achieve the highest levels of customer satisfaction and value while effectively exploiting the competencies of all organizations in the supply chain.
