Chain Analysis
The chain analysis is an internal analysis based on your context's systems and their interfaces. The chain analysis feature creates a condensed overview of a system's relations to other systems and analyzes the impact of system interface changes. This impact is mapped and traced across systems in the N2 diagram.
The Chain Analysis Feature
The chain analysis consists of outputs and inputs on two levels:
The first level shows the selected systems interfaces output and input.
The second level shows the selected systems interface and their system interfaces output and input.
A system's 1st level output and input are displayed below. The output is marked blue, and the input is marked yellow.
Below is an example of a system's 1st & 2nd level output.
The illustration exemplifies a system's 1st level interface output and 2nd level interface output. As an example, the Sensor system will be analyzed in the chain analysis:
The Sensor system has a 1st level interface output (BC1) to the Central Process system. The Central Process system is an input system.
The Central Process system has an interface output (BB1) to the Motor system. This is regarded as a 2nd level interface output because the Sensor system is being analyzed.
NB! If the analysis were on 1st level interface output, we would only see the interface output (BC1) from the Sensor system to the Central Process system.
