Welcome

The Systems Engineering Toolkit web app is a web based user interface that provide views of the model as well as tools to analyse and manipulate the model.

The model is an abstract representation of the system of interest. The system of interest, or SOI for short, is:

(1) The system whose life cycle is under consideration (ISO/IEC/IEEE 2015),

(2) The system of interest to an observer. (Bertalanffy 1968)

When designing any system, hereafter referred to as the system of interest (SOI), there are three things that need to be accounted for:

  1. The SOI itself,
  2. The system used to develop the SOI, in this case: the engineering team, their organisation and their tools.
  3. The external environment, over which the designer of the SOI has no control.

At the heart of the SE Toolkit is the model of the SOI.

The model is an abstract representation of the SOI.

The SE Toolkit web app provides tools to manipulate the model of the SOI.

The SE Toolkit web app provides tools to analyse the model of the SOI.

Support for model schema version 0.9 will be discontinued with the release of version 0.15, which is anticipated to take place in the first half of 2024.

The SE Toolkit web app upgrades models automatically when they are imported. To upgrade a model, simply import it into the SE Toolkit web app and download it again. Make sure to store the upgraded model safely.
