The terms of reference are created during the earlier stages of project management by the founders of the project in question, immediately after the approval of a project business case. They are documented by the project manager and presented to the project sponsor or sponsors for approval.
Reference design refers to a technical blueprint of a system that is intended for others to copy. It contains the essential elements of the system; however, third parties may enhance or modify the design as required. [1] When discussing computer designs, the concept is generally known as a reference platform.
A key aspect of specification by example is creating a single source of truth about required changes from all perspectives. When business analysts work on their own documents, software developers maintain their own documentation and testers maintain a separate set of functional tests, software delivery effectiveness is significantly reduced by the need to constantly coordinate and synchronise ...
A software design description (a.k.a. software design document or SDD; just design document; also Software Design Specification) is a representation of a software design that is to be used for recording design information, addressing various design concerns, and communicating that information to the design’s stakeholders.
For example, consider the accounts payable department when processing an invoice. With an accounting information system, an accounts payable clerk enters the invoice, provided by a vendor, into the system where it is then stored in the database. When goods from the vendor are received, a receipt is created and also entered into the AIS.
A software reference architecture is a software architecture [1] where the structures and respective elements and relations provide templates for concrete architectures in a particular domain or in a family of software systems. An implementation of a reference architecture is called a framework or an application platform.
Software design usually is directed by goals for the resulting system and involves problem-solving and planning – including both high-level software architecture and low-level component and algorithm design. In terms of the waterfall development process, software design is the activity of following requirements specification and before coding ...
It covers the process of controlling modifications to the system's design, hardware, firmware, software, and documentation. Configuration Status Accounting: includes the process of recording and reporting configuration item descriptions (e.g., hardware, software, firmware, etc.) and all departures from the baseline during design and production.
