Telelogic White Paper Figure 2 shows a component diagram for the CMS illustrating two separate Web applications and a number of services and components. Each service fulfills a core business function, and is composed of one or more reusable components that can be deployed and reused across multiple applications and services. The Claim Severity Component is an example of a component deployed and used by both the workflow and adjudication service to help score the severity of the claim and ensure that the appropriate rules are applied during adjudication. In this example, component reuse helps speed the development of applications and services through a combination of custom development and component assembly. Figure 2 - Component Diagram Illustrating the CMS Services and Components Managing the development of these components is crucial to realizing the advantages of CBD and SOA. Yet managing this development is also difficult, not only because of complex technical challenges, but also due to the essential complexity surrounding software development. Often not considered a significant part of a CBD strategy, a robust Software Configuration and Change Management (SCCM) solution is a fundamental aspect to consider for project success. Telelogic Synergy™ and Change™ is a product suite for change and Configuration Management that can help ease your pains surrounding enterprise CBD and SOA initiatives. Before delving into how the Synergy and Change contribute to CBD, let’s first examine the benefits of CBD followed by some common impediments. Benefits of Software Reuse Software reuse has been considered the “holy grail” of software development for decades. The business value realized through successful reuse initiatives can offer substantial rewards, which explains why so many organizations are pursuing this goal. Below are a few of the significant advantages teams stand to realize through a successful CBD initiative for achieving reuse: • Reduced time-to-market: CBD emphasizes assembly of applications from pre-built parts. Robust components have already undergone rigid testing cycles. Because components are modularized and independent units, they can often be developed in parallel. Given the proper collaboration and testing tools, teams can work effectively even when dispersed across the globe. • Higher Quality: Components are discreet fine grained units of behavior, and automated tests can be written to ensure that each component undergoes a strict test lifecycle. As components are field tested as they are consumed by an increasing number of applications, developers gain increased trust in CBD. • Decreased cost: Increased component modularity helps isolate software functions, providing an efficient mechanism to upgrade a component without impacting an entire application. Although the short-term cost of CBD is typically greater than developing applications in silos, as your component reuse increases, the reduced time-to-market and higher quality benefits offer substantial long-term savings. • Increased Organizational Agility: The ability of IT to respond quickly to business needs is imperative in today’s dynamic business climate. As the component inventory of your organization grows, teams are able to enhance application functionality by leveraging pre-built software components. Additionally, because change requests of the business stakeholders are isolated to discreet units of functionality, change can be made in isolation and released to all component consumers.
