Answer to Question 1

A

Answer to Question 2

System integration is by far the biggest software problem IT managers face. With the increased need for supporting inter-organizational supply chains, the level of complexity becomes
exponential. The increasing complexity of IT, with systems from various eras and technologies that must coexist and even work together, makes the integration challenge even more
difficult to solve. IT managers have long strived to integrate the information together. However, integration is complex and expensive, and it can cause systems to crash. Competitive pressures have raised the importance of integrating business processes and, thus, the underlying information systems. The trend away from in-house software development toward the use of off-the-shelf software has furthered the need for integration. Online business requires integrating systems across organizations.
