ARCH.118 Identify implementation constraints on the subsystem solution

RCAMT-533 - Define a process step to take the tension from comp/com under consideration that may the subsystem boundary/subsystem constraint Finished

Goal

Identify constraints from the implementation strategy and implementation technology on the subsystem architecture characteristics, subsystem design characteristics, or subsystem implementation techniques.

Requirements met by this process stepISO 15288 6.4.7.3 a 2)
Inputs

AMOD-080 Subsystem option sketch

AMOD-116 System implementation constraints

OutputsAMOD-075 Subsystem implementation constraints
Methodology

To avoid selecting a subsystem architecture that can never be implemented in reality, it is necessary to determine limitations beforehand and to take them into account in the subsystem boundary definition.

E.g. the platform physical limits/boundaries/constraints... (threshold values that are impossible to go beyond due to physics and/or technology state of the art).

The system level implementation constraints AMOD-116 System implementation constraints should be consistent with the subsystem implementation constraints. At system level, some of the physical constraints described above may already be known. 

Note: This includes current or anticipated limitations of the chosen implementation technology, acquirer furnished materials or system elements for adaptation and limitations resulting from the use of required implementation enabling systems.
