How do firms measure returns from these substantial investments in information technology? Henry C. Lucas, effectively answers this question by providing a creative and reliable framework for measuring the competitive advantages and profits gained through investments in state-of-the-art information systems. There is value in information technology, and it is possible to show returns, Lucas argues--unfortunately this value just doesn't always show up clearly on the bottom line of a ledger. In five expertly presented sections, he spells out exactly what businesses can expect from their information technology investments - some investments create a measurable value, some do not, but all are important nonetheless. Through a precise mix of frameworks and models, such as an Investment Opportunities Matrix, and punctuated with real examples from successful firms, this is the first book to allow executives to see exactly how their information technology investment can be expected to return value, thereby maximizing their advantages in an age of global competitiveness. Indeed, firms who manage their information systems most efficiently are best suited to succeed in a rapidly evolving marketplace.
