GoalDefine the responsibilities (functional scope) of logical components
Requirements met by this process step

ISO 15288 6.4.4.3 c) 3, d)
EN 50126-1 7.6.1

Inputs

AMOD-125 Logical architecture definition

AMOD-081 Logical functional flow definition (single system capability realisation)

AMOD-088 Consolidated logical functional flow definition

Method for definition of logical components

Method for definition of system interfaces

Outputs

AMOD-125 Logical architecture definition (per realised capability)

AMOD-125 Logical architecture definition (logical component consolidated)

Methodology

Note: This activity needs to be carried out after or in parallel with other activities under ARCH.921 and ARCH.922.

Tasks: 

  1. Allocate the logical functions to logical components
  2. Identify superfluous logical components
  3. Identify missing logical components
  4. Identify duplicate logical functions

See Allocation of logical functions to logical components for method and guidance.


A particular case for interfacing functions: see Method for definition of system interfaces chapter Allocation of interfacing functions to logical components at logical architecture for method and guidance.
