Cognizant has been a pioneer in using agile development methodologies effectively across distributed teams. In the past, Cognizant used a mix of tools to support the development process, including Visual Studio Professional 2005 for development, Microsoft Visual Source Safe for source code control, and other open-source and homegrown tools for managing business requirements, tasks, changes and defects. The mixed tool set, however, did little to support and streamline adherence to agile development principles. Instead, it hampered team output, consumed additional time and impeded communication. Specific problem areas included: offline traceability of artifacts, frequent transitions between multiple tools used for design, testing, reviews and task tracking, and excessive time spent on creating reports. Our company was experiencing continued and significant growth. To keep pace, it was important for us to increase the productivity of our employees with optimized business solutions, explains Rajashree Natarajan, Asst Vice President, Process and Tools Group, Cognizant. We needed a comprehensive, enterprise-class solution for managing all aspects of the development process and we were eager to find a solution. Cognizant anticipated the need to streamline the company s development process and build a more integrated and extensible system architecture to keep pace with the company s growth rate. The company aimed to strengthen its entire IT infrastructure with the ultimate goal of boosting productivity and accelerating cycle-time.

3 Architecture: Team Foundation Server Integration with Cognizant Enterprise Project Management Solution To optimize its Microsoft solution development environment, Cognizant implemented a comprehensive ALM solution based on Microsoft Visual Studio Team System, which extends the Visual Studio integrated development experience from the individual developer to the entire development team by delivering powerful new role-based tools for all development-related users, along with a centralized repository for project data. Cognizant s ALM solution called SPECTA is built on Visual Studio Team System and Team Foundation Server. It provides multidisciplined teams with an integrated toolset for requirements management, task management, defect management, change management, build management, version management, architecture, design, development, database development and testing of applications. Team members can continuously collaborate and utilize a complete set of tools and guidance at every step of the application life cycle. The integration between the integrated development environment (IDE), source control, build tools, team portal and workitems like features, tasks, bugs and changes and the easy extensibility points provided by Team Foundation Server were the key deciding factors for the solution, comments Sai Krupa Sagar, Chief Architect, Cognizant. The new technology contained many significant features that helped us optimize our development process using the extensible ALM platform. Architecture Overview SPECTA comprises of a customized TFS process template and a set of extensions as illustrated in the figure. The TFS process template supports the best practices of Feature-driven Development (FDD) and Scrum agile methodologies. The extensions included new work-items, reports, check-in policies and plug-ins that support standard engineering practices like Build Verification Tests, Continuous Integration and Contextual Guidance. It also includes a synchronization engine that integrates with Cognizant s Intelligent Delivery Ecosystem Cognizant 2.0. The ecosystem is an enterprise-wide collaborative platform for workflow automation, process orchestration, and seamless knowledge management. One of the widely used SPECTA plug-ins provides integration between Microsoft Outlook and Team Foundation Server. Project planning and initial setup is enabled through the advanced framework provided by Cognizant 2.0. When this information is synched with SPECTA, an equivalent team project is created on Team Foundation Server and work-items are automatically populated. Thereafter, developers use Visual Studio Team System to perform all their tasks

The Project Manager uses the multidimensional reports provided by Team Foundation Server to track status and manage risks. The synch-engine periodically synchs up work-item data between Team Foundation Server and Cognizant 2.0. This enables different stakeholders to access the advanced planning, reporting and knowledge management capabilities of Cognizant 2.0 while the development and testing teams access the integrated toolset and engineering capabilities provided by SPECTA extensions on Team Foundation Server. Several Visual Studio plug-ins make data entry easier and intuitive. Business Analysts can create and manage requirements through the familiar interface of Microsoft Outlook Project Managers can manage work-items through multiple channels using Microsoft Outlook 2007 or through Microsoft Project or Microsoft Excel or through a browser interface. Additionally, stakeholders can view multi-dimensional reports instantaneously through a Silverlight powered dashboard. Custom workflows are implemented to automate the usually offline processes of reviews, change, test and defect management. Building all this on enterpriseclass server products like Microsoft Team Foundation Server and Microsoft SQL Server Developer Tools System 2008 Microsoft Visual Studio 2008 Team Foundation Server Microsoft Office 2007 Tools helped Cognizant to deploy the solution faster. Team Foundation Server gave us the flexibility to customize work item types and other project artifacts to support our own way of working, explains Sai Krupa Sagar. It integrates all aspects of software development item tracking, version control, builds, and reporting into a single collaboration environment. Implementation Overview The initial version of the solution was a result of Cognizant s early involvement in the adoption program of Team Foundation Server 2005 even before its commercial availability. Since then, there have been five major releases of SPECTA, each with new, additional features and customizations to address several customer requirements. Actually, the agile process promoted by SPECTA, was followed to build the SPECTA solution using distributed teams. The actual implementation involved modifying XML files, writing custom code in.net, building reports in SQL Server Reporting Services and customizing the SharePoint portal. The adaptable architecture of Team Foundation Server and the generous extensibility mechanisms provided by the architecture helped us extend and customize TFS behavior with minimum effort and shorter cycle time, adds Sai Krupa Sagar. Benefits With the new solution, Cognizant has improved its ability to successfully follow agile methodologies even in a distributed delivery model. Development groups are now more productive; and communication and collaboration are stronger, and the agile methods accommodate change more efficiently. All this has increased customer satisfaction and is becoming a strong

5 competitive advantage for Cognizant. Several of Cognizant s customers are using variants of the SPECTA solution within their enterprises. Cognizant has helped build custom extensions and reports as needed. Cognizant s SPECTA built on Microsoft Visual Studio Team System provides an integrated, optimal delivery environment that increases productivity, for all roles, by eliminating or reducing switches between multiple applications, tools and activities, says Rajashree Natarajan. Enhances Communication and Collaboration By implementing SPECTA with Visual Studio Team System on Visual Studio Team System Team Foundation Server, Cognizant has a tightly integrated environment along with the tools required to facilitate a more collaborative development process. A central repository for all project data helps improve team collaboration by keeping everyone informed of the project status. Adopting System has allowed the development team to significantly improve its ability to collaborate between geographies and time zones. Real time integration with Cognizant 2.0 vastly increased the collaboration quotient by fusing Visual Studio based developer environment into the enterprise wide collaboration platform of Cognizant 2.0. Together, this integrated environment enables seamless communication between developers, testers and other stakeholders enabling all project members to work in concert toward a common goal. Accelerates Cycle-time by 10 Percent The new solution provides multiple areas and opportunities for collaboration among the development team. Features such as, a shared team portal, integrated change management, and a common data repository boost collaboration among developers, consequently cutting the time and cost of application lifecycle management and putting applications into production more quickly and cost-effectively. The availability of information across the application lifecycle has created a more unified work environment. With all the information at our fingertip and the integrated environment we are seeing cycle-time improvements of around 10 percent, says Rajashree Natarajan. This enables us to keep up with the needs of our business. Additionally, we are able to solve our customer s business problems faster and with less effort. The company s software projects involve many individuals with different roles and responsibilities at various stages of the development cycle. To aid in the distribution of work, the SPECTA process includes a series of out-of-the-box roles, such as business analyst, architect, developer, tester, scrum master, feature owner and project manager, and a set of tools and practices specific to each role. The SPECTA extensions on Team Foundation Server, monitors and integrates these roles. The less number of switches we have, between different tools and applications, the less room there is for errors and shorter the time required to complete most activities, states Sai Krupa Sagar. Reduces Cost of Software Quality Software quality has improved because the new development environment helps team members to detect potential errors earlier in the project life cycle. The customized methodology imbedded into Team Foundation Server guarantees quality throughout the software development lifecycle and ensures that all steps in the workflow are followed and completed correctly.
