Requirements Management, Requirements Capture and Model Based Systems Engineering with Cradle from 3SL
Cradle provides a full lifecycle support framework from requirements capture through model driven systems engineering to implementation, testing and support. Enabling you to develop better projects from concept . . . to creation.

Welcome to the 3SL Cradle-5.7
Evaluation Start-Up

The functionality of the system was analysed and this produced the behaviour of the system as modelled in the Behaviour diagrams. The list of essential functions was derived from these diagrams.

The implementation model is demonstrated by the Physical Architecture Diagram. This provides a diagram of the system as a physical entity. From this a list of Implementation Specifications is derived.

Linking the Implementation Specifications to the Essential Functions will show how the system performs and ties the essential model to the implementation model.

This is performed in the same way as linking the functions to the requirements:

Cross References

At this point the requirements are linked to functions which in-turn are linked to architecture. You may wish to display this as a table or a matrix:

Matrix Functions-Architecture

You may also display the transient links of requirements linked to architecture via the combined links through functions:

Matrix Requirements - Architecture

Steps:

  1. Create a project using the Cradle Menu Done
  2. Capture requirements from a Microsoft® Word® documentDone
  3. Import Diagrams in Toolset or WorkBench Done
  4. Manually link Requirements to Functions Done
  5. Produce matrix from requirements to functionsDone
  6. Produce matrix from functions to Architecture You Are Here.
  7. Create User Requirement Document in Publisher.
  8. Produce a final document showing links from Requirements to Functions, links from Functions to Architecture and transient links from Requirements to Architecture and the Final Specifications.
