Subcomponent: System Design and Development (SD)
Definition: System Design and Development is the characteristics of the functional and technical requirements for a data system, and the development and implementation of a data system based on those requirements
The System Design and Development subcomponent addresses the characteristics of the functional and technical requirements for a data system, and the development and implementation of a data system based on those requirements. This subcomponent includes the process of defining the architecture, database, system standards and components, and the data elements. Part C and Section 619 state staff involvement, input, and review throughout the entire process are a hallmark of a high-quality data system.
The purpose of the System Design and Development subcomponent is to assist states in creating and supporting a data system based on the Part C and Section 619 program requirements as articulated in the purpose and vision. System design and development is the means by which the operational needs of the program staff and other users are translated into a functional and technical infrastructure that will meet those needs. This subcomponent supports the development of new data systems and enhancements to existing data systems.
This subcomponent was developed around the phases and processes of a standard System Development Life Cycle (SDLC), which includes (1) system initiation; (2) system requirements analysis; (3) system design; (4) system development; (5) system acceptance; and (6) system deployment. This subcomponent begins once data governance approves a high-level plan for a new data system or data system enhancement and ends when the system or enhancement is deployed. Ongoing maintenance activities and operations to support the system are addressed in the Data Governance and Management subcomponent, and the evaluation of the data system to determine needed enhancements is addressed in the Sustainability subcomponent. Designing and developing a data system involves numerous technical requirements and processes usually performed by the Information Technology (IT) team and not by Part C and Section 619 staff. Because the subcomponent was developed for use by Part C and Section 619 staff, these technical activities are not addressed within it.
This subcomponent consists of three sections, each of which addresses two phases of the SDLC. The first section addresses the first two phases of the life cycle: initiation of a new data system or enhancement, and system requirements analysis. The purpose of system requirements analysis is to obtain a thorough and detailed understanding of the business needs and to break those into discrete requirements. These requirements must then be clearly defined, reviewed, and agreed upon by the state Part C and Section 619 staff. Sufficient time and resources should be allocated during system requirements analysis to bring stakeholders and their interests into the process. Subject-matter experts in Part C and Section 619 must also be actively involved in defining business requirements. During system requirements analysis, a set of functional specifications for the data system development or enhancement are created through an iterative process. These specifications provide the foundation for all subsequent design and development work.
The first section also addresses critical data elements and features that should be contained in a high-quality data system. A fundamental purpose of the framework is to help states develop more powerful and comprehensive data systems, and such systems include the suggested data elements and features. Although many state data systems do not have all of the suggested data elements and features, the purpose of the framework is to help states move toward such systems.
The second section addresses the third and fourth phases of the SDLC: system design and system development. Part C and Section 619 staff may not be directly involved in the technical aspects of the system design and construction work, but the state should have a process in place for Part C and Section 619 state staff to work and communicate with the IT team, providing feedback, input, and approval when necessary.
The third section addresses the fifth and sixth phases of the SDLC: system acceptance and system deployment. Successful acceptance testing is the final opportunity to establish that the data system performs as expected in an environment that closely simulates one which will be used after deployment. During acceptance testing, end users thoroughly test the data system as if it were fully implemented. An end user is an individual who uses a computer (data) system after it has been fully developed and deployed. The term is based on the idea that the “end goal” of a software or hardware product is to be useful to the consumer. System acceptance also includes creating or updating supporting documentation and reference materials. Deployment refers to the launch of the new data system or enhancement.
