Litware has a main office and five branch offices. Existing Environment - Application Architecture - The company's primary application is a single monolithic retirement fund management system based on ASP.NET web forms that use logic written in VB.NET. Some new sections of the application are written in C#. Variations of the application are created for individual customers. Currently, there are more than 80 live code branches in the application's code base. The application was developed by using Microsoft Visual Studio. Source code is stored in Team Foundation Server (TFS) in the main office. The branch offices access the source code by using TFS proxy servers. Architectural Issues - Litware focuses on writing new code for customers. No resources are provided to refactor or remove existing code. Changes to the code base take a long time, as dependencies are not obvious to individual developers. Merge operations of the code often take months and involve many developers. Code merging frequently introduces bugs that are difficult to locate and resolve. Customers report that ownership costs of the retirement fund management system increase continually. The need to merge unrelated code makes even minor code changes expensive. Customers report that bug reporting is overly complex. Requirements - Planned changes - Litware plans to develop a new suite of applications for investment planning. The investment planning applications will require only minor integration with the existing retirement fund management system. The investment planning applications suite will include one multi-tier web application and two iOS mobile applications. One mobile application will be used by employees; the other will be used by customers. Litware plans to move to a more agile development methodology. Shared code will be extracted into a series of packages. Litware has started an internal cloud transformation process and plans to use cloud-based services whenever suitable. Litware wants to become proactive in detecting failures, rather than always waiting for customer bug reports. Technical requirements - The company's investment planning applications suite must meet the following requirements: New incoming
