Does technology and Innovation Management improve Market Position? Empirical Evidence from Innovating Firms in South Africa

There is a growing recognition of the central role of technology and knowledge management for market success of organizations. Little is empirically know, however, about this relationship. Drawing on the South African Innovation Survey, a unique dataset on innovative behavior of South African firms in manufacturing and services, this paper investigates the question to what extent and in which ways do technology and innovation management activities affect firms’ market position. Findings show that conducting technology strategy activities pays out. Moreover, especially a combination of internal and external technology audits seems to be beneficial for organizational performance

The definitive publisher-authenticated version: E.A. Silver, D.P. Bischak, and G.J.C. da Silveira, “An efficient method for calculating the minimum distance from an operating point to a specific (hyberbolic) efficient frontier,” IMA Journal of Management Mathematics 20:3 (2009), 251–261 is available online at doi:10.1093/imaman/dpn023. Deposited according to policy found on Sherpa/Romeo July 12, 2012.This paper is concerned with movement from a current operating point so as to reach a two-dimensional, efficient frontier. After a discussion of different criteria for deciding on which point on the frontier to target, we focus, as an illustration, on a particular inventory management context and use of the criterion of minimum distance from the current point to the frontier. Specifically, the efficient frontier turns out to be an hyperbola in a two-dimensional representation of total (across a population of items) average stock (in monetary units) versus total fixed costs of replenishments per year. Any current (or proposed) operating strategy, differing from the class along the frontier, is located above the frontier. Finding the minimum distance from the current point to the frontier requires determining the smallest root of a quartic equation within a restricted range.Ye
