How to write interface design description

A description of the usecase view of the software architecture. The Use Case View is important input to the selection of the set of scenarios andor use cases that are the focus of an iteration. It describes the set of scenarios andor use cases that represent some significant, central functionality.

3. 1 The Interface Design Description (IDD) describes the interface characteristics of one or more systems, subsystems, Hardware Configuration Items (HWCIs), Computer Software Configuration Items (CSCIs), manual operations, or other system components. SDD stands for software design document or software design description. What is in a software design document? The software design document (SDD) typically describes a software product's data design, architecture design, A software design description (a.

k. a. software design document or SDD), also Software Design Specification is a written description of a software product, that a software designer writes in order to give a software development team overall guidance to the architecture of the software project.

An SDD usually accompanies an architecture An Interface Control Document (ICD) describes the interworking of two elements of a system that share a common interface.

For example, a communications interface is described in terms of data items and messages passed, protocols observed and timing and sequencing of events. Version 1. 0 Information& Design May 1 2002 [Version control is important if the document is to be the formal repository of the user interface specification. [Project User Interface Description Page 8 of 8 Elements The following is a list of all elements in this screen.

[Some sample elements included here. Use a proforma to ensure Each design entity described in the SDD must satisfy a specific requirement specified in the Software Requirements Specification or an internal design requirement (i. e. an internal need for portability of a software product across many operating systems may create the need for an operating system services interface module). The purpose of the Software Design Document is to provide a description of the design of a system fully enough to allow for software development to proceed with an understanding of what is to be built and how it is expected to built.
