Intention

This wiki page is intended as a guideline for verification and design answering the question: What is needed to close a design step related to a design phase.

Definition

The design phase is defined inside the CENELEC norm EN50126 and EN50128. The design step is defined as the activity required related to a subtopic of a design phase which is needed to close the phase related to this topic. The product scope is the scope of the product intended to be developed.

Background

Within this wiki page a high level overview is translated into a minimum list of activities required to start the closing verification. Underneath the list of activities do not mention all activities needed to close a phase but mention the minimum stet of input data to start verification on the phase in an agile way.

Activities needed to close the design step: General Step

  1. tarceability on system level
  2. methods, tools and techniques used
  3. suporting documents are needed 'on top of the model'

Activities needed to close the design step: Architecture and Design Phase

  1. Functional Architecture Specification (step 1)

    • functional architecture containing the list of initial functions intended to cover all functionalities within the product scope
    • for every function a specific description of it's functionality and the traceability to the SRS
    • input and output to/ from each function including all overall system interfaces to which the input/ output relates
  2. Software Design Specification (step 2)

    • component architecture containing the allocation of the functions to the software modules
    • for every function a specific description of it's functionality and the traceability to the SRS allocating the functionality to the components
    • input and output to/ from each function including all overall system interfaces to which the input/ output relates
