Software & Systems Development

Vangent's approach to software and systems
development ensures that our customers' IT solutions are aligned with their business and IT architecture, and that they are implemented in a way that reduces time, cost, and risk.

Vangent's adaptable Capability Maturity Model Integration (CMMI)-compliant life cycles deliver value to our customers by providing measurable and predictable outcomes. Our industry thought leaders and visionaries have developed a step-by-step Software Development Life Cycle (SDLC) that can be adapted for any project. This detailed, iterative, and sequential set of activities helps mitigate risks and deliver large-scale, complex systems on time and within budget.

Vangent's SDLC comprises the following phases and activities:

Conduct Inception Phase

	Develops the vision for the solution. Works with key stakeholders and end users to solidify the solution features
	Models business processes in Business Process Modeling Notation (BPMN)
	Models the functional (use cases) and nonfunctional requirements
	Develops the high-level solution architecture that provides the overall context for the solution
	Defines a software development plan to provide an overall project management structure for the development effort
	Develops proof of concepts for high-risk areas

Conduct Elaboration Phase

	Defines the software requirements, solution architecture, and software development plan
	Designs interfaces between major services and components
	Builds an executable architecture to assess the architecture design prior to large-scale construction, as well as to ensure interoperability

Conduct Construction Phase

	Implements solution through successive iterations based on the executable architecture
	Tests the solution continuously, using automated testing whenever possible
	Prepares the solution for the production environment

Conduct Transition Phase

	Finalizes software implementation and testing
	Deploys the solution into the production environment
