1. Enterprises should invest in business architecture transformation to address long-standing problems in IT like high costs, low business agility, and difficulties changing legacy systems. 2. These problems stem from the way IT has developed over 20+ years with an application-centric and point-to-point integration approach, leading to complex and rigid architectures. 3. Computer science offers a solution in Enterprise Service Orchestration Architecture (ESOA) which addresses these problems by standardizing integration through an enterprise service bus and implementing business processes as executable flows.
