Strategy book for IT managers and business managers
on 28 July 2009
Enterprise Architecture as Strategy is a book that will be useful to both business managers and information technology managers. The book does not describe technology in detail, but instead offers a best-practice strategy for companies who want to ensure their business processes and information technology architecture are structured for future growth and agility.
The book starts by discussing the problems that many businesses have of silo systems and redundant data. It then draws on case studies from surveys involving more than 400 companies to propose a business-led enterprise architecture strategy. I felt this book offered a clear strategy that seems achievable, practicable and focused.
The authors show how companies can consider their direction based on a series of models. These include:
Operating model - allowing the company to consider how integrated and standardised its processes and systems need to be. For many companies the enterprise architecture strategy involves producing lots of diagrams and analyses of existing and hoped-for system capabilities; far better, the authors found, to consider the operating model and then focus on processes, data, technologies and customer interfaces that will enable this to be realised.
Enterprise architecture model - defining how the business processes and information technology infrastructure will be organised to reflect the operating model. The authors offer an easily grasped and intuitive structure for mapping the enterprise architecture. The stages that companies should go through in order to reach the architectural goal are also considered.
IT engagement model - governance mechanisms that will ensure that the company and its information technology projects achieve both local and company-wide objectives. The authors draw on best-practice case studies to offer advice and recommendations.
