Technical Solutions Provider – Workflow Application

Business Need
The client, a provider of comprehensive technical solutions, wanted to expand their technology service offerings to the Federal government by building expertise in BEA’s WebLogic Integration (WLI) product. As an alternative to conducting extensive training, The Client believed it could get a significant jumpstart by reconstructing an existing purchase request workflow application using WLI to gain valuable implementation experience. While The Client did have experience building workflow applications, the company lacked the BEA-specific knowledge required to actually develop systems built on WLI. The Client management felt that if they could find outside resources to provide the needed BEA expertise, they could team their developers with these resources to transition the knowledge and move quickly through the learning curve.

The Solution
The Client engaged Excella to develop the purchase request workflow application using WLI and transition the knowledge to an internal team of developers. Excella first worked with The Client management to determine the scope of the development, workflow, and business rules, as well as what constituted a successful knowledge transfer. Excella then developed all components of the new application, including the user interface, workflow, business logic, and database. Throughout the engagement, Excella managed the team of internal developers so that they were learning the necessary skills to effectively take ownership of the application. Finally, Excella redeployed the new WLI application on The Client’s corporate servers and delivered comprehensive documentation, including screen flows, data models, and step-by-step procedures for developing WLI-based applications.

Technologies Used
The target architecture of the system included Microsoft IIS web server, BEA WebLogic Integration 2.1, an Oracle database, and a Microsoft SQL Server database.
