ARCH.180 Define logical component candidates

Goal

Define logical component candidates based on splitting principles.

Requirements met by this process stepISO15288 6.4.4.3 c)
Inputs

Concepts and other information from railway and RAMS experts.

ARCH.M.070 Method for definition of architectural elements

OutputsAMOD-125 Logical architecture definition
Methodology

This process step should be carried out together with ARCH.182 Split the system functions.

Note: It is important to recognise that not every single one of these candidates will actually be needed (Final check in ARCH.181 Reconcile candidate logical components).

See Method for definition of logical components for method and guidance.

Tools and non-human resources

Team for Capella

Cardinality

One off after all possible logical splitting principles have been identified. But with allowed iterations after different candidates emerge from review steps.

Completion criteria

The output view complies with its modelling rules.

Maximal set of logical component candiates defined and implemented in a manoevreable number of logical components.

Design review

ARCH.R.5 Logical capability review

ARCH.R.6 Logical review - consolidated
