Convergence of Business Architecture, Business Process Architecture, Enterprise Architecture and Service-Oriented Architecture

Organizations have always been challenged by cost reduction and need for growth. Recently, the economic climate has taken these challenges to a new and unprecedented level. The time to instrument changes in organizations has become shorter than ever. Consequently, business transformation is not longer a project but a continued improvement initiative. With this new normal, the importance and role of architectures in business and information technology should be revisited. Questions such as "How does the ability of an enterprise to respond to change is enhanced / impeded by these architectures ?" and "Why do organizations need so many 'architectures' ?" are being formulated by business leaders and analyst firms.
