The Solution Design stage begins upon Customer and stakeholder approval of the System Requirements Review (SRR) and its associated artifacts. Solution Design is specific to Scrum projects only. Design is not typically required for Kanban process cycles involving Problem Reports and smaller “break-fix” tasks. Partnet’s Solution Design stage consists of two elements: functional design and technical design.
Functional Design: User stories form the basis for functional design and planning. User stories are short, textual statements corresponding to a specific feature or business need that the software solution must fulfill. Requirement Managers write user stories based on the approved solution requirements. During functional design, user-story reviews are convened with members of the Delivery Team to formally discuss each user story in detail and specify its acceptance criteria. All outstanding questions and assumptions are documented for follow-up with the Customer and other external stakeholders. User stories are then allocated into specific development tasks and subtasks that constitute the Product Backlog.
Technical Design: In parallel with user-story reviews, our development and engineering group prepares the technical design solution. Aspects of the technical design include:
Analysis of necessary changes to the general solution architecture.
Review new interfaces for third parties.
Protection of system security posture.
Identification of required hardware components, operating systems, and network architecture.
Research supporting software technologies and libraries.
Determination of necessary changes to the data model(s).
Partnet convenes an internal design review to collect and incorporate final feedback on the designed solution from Software Developers, Test Engineers, Configuration Managers, Project Managers, security specialists, and support staff. This review focuses on specific items affecting the solution design, such as:
Ensuring the design minimizes development and maintenance costs.
Identifying opportunities for business-user configuration (i.e., administrative utilities that allow the Customer to configure and manage the software without new […]
