Abstract
Organizations increasingly are adopting information technology (IT) in order to automate their business processes to be competitive in marketplace. The greater evolving interdependence between information technology and business processes has created various opportunities for technologies and businesses. Therefore, co-evolutionary changes generate successes in business organizations. As evolution requirements either in business process or information technology can have an impact onto another, it is necessary to understand and manage the requirements in such a manner that consistency is maintained. This paper offers an insight of requirements analysis for co-evolution of business and IT. In this study we have used an observation of a bank in Saudi Arabia to assess the requirements of co-evolution of business and IT.
