Mining for Digital Gold: Technology Due Diligence for CIOs
How do CIOs decide which technologies to acquire and deploy? This paper presents a set of criteria used by CIOs to vet technology decisions and spread their technology bets. There is insight to be gained by defining, understanding, and applying these criteria. In fact, the more we understand the technology due diligence process the better our understanding of technology leverage becomes. Ultima...
متن کاملAncient Gold Mining Activities in India - An Overview
Gold was obtained through washing or panning of the river sands during initial periods of civilisation. With the advent of knowledge of metallurgical processing of ores it was recovered through mining of in-situ quartz reefs, and then from auriferous sulphide ores. The metal mining activities are evidenced in the form of large number of ‘ancient metal mines’ or ‘old workings’ and ‘placer mining...
متن کاملGlobalisation , Productivity and Technology
Recent empirical evidences show negative relationship between outsourcing and profitability. This paper provides a theoretical explanation for this phenomenon. In an oligopoly model, we show that firms earn lower profits in the outsourcing equilibrium compared to the situation where neither firm does outsourcing, and it holds irrespective of the intensity of competition. So, outsourcing creates...
متن کاملGold Nanostructures in Biomedical Technology
