Development Methodologies. The XXX development will follow an iterative approach. This allows some of the “easy wins” to be tackled first and ensures that a complete system is available for use as early in the project as possible. Later development iterations can then tackle more complex requirements and those requirements that could not be addressed until earlier requirements had been addressed. Allocation of development activity to each iteration is, however, constrained by the dependencies outlined in 2.1(bullet 2) above. This approach means that new functionality can be given to users sooner than the more traditional waterfall approach, allowing them to find flaws while there is still time to correct them in later iterations. It also means that later iterations of the XXX design can be targeted at requirements which may not yet have become clear as part of the requirements elicitation process so far. This document details those components of the XXX and their integration within the wider Europeana Inside environment that will be considered as part of Iteration 1 of the development process. Further development iterations will be considered by later versions of this document.
Development Methodologies. The Contractor may support a Service-Oriented Architecture (SOA) that is a flexible set of design principles used during the phases of systems development and integration which will be specified at the task order level. The deployed SOA-based architecture will be deployed on a secure, scalable, interoperable and dynamic platform that has the end to end visibility and manageability from application services to the networking components level and that can be used within multiple domains. For VA specific task orders, the Contractor shall support VA efforts IAW the Project Management Accountability System (PMAS) that mandates all new VA IT projects/programs use an incremental development approach, requiring frequent delivery milestones that deliver new capabilities for business sponsors to test and accept functionality. Implemented by the Assistant Secretary for IT, PMAS is a VA-wide mandate to better empower the OI&T Project Managers and teams to meet their mission: delivering world-class IT products that meet business needs on time and within budget. For VA specific task orders, the Contractor shall utilize ProPath, the OI&T-wide process management tool that assists in the execution of an IT project (including adherence to PMAS standards). It is a one-stop shop providing critical links to the formal approved processes, artifacts, and templates to assist project teams in facilitating their PMAS-compliant work. ProPath is used to build schedules to meet project requirements, regardless of the development methodology employed. The Contractor shall use an incremental development methodology such as Agile unless otherwise specified at the task order level.

It also means that later iterations of the XXX design can be targeted at requirements which may not yet have become clear as part of the requirements elicitation process so far. Development tasks in each iteration were assigned numbers relating to the area of functionality being developed. As the iterative development progressed, some functional areas were merged into a single module and other functions split across modules. It is therefore important to note that there is not a simple 1:1 mapping between functionality and modules.
