Idea of system processes in Automotive SPICE®: SYS. 1 Requirements Elicitation er m to s Cu t ec j o Pr ? Customer Requirements CReq 1 CReq 4 CReq 2 CReq 3 CReq 5 CReq n ! Customer Requirements SYS. 1 Requirements Elicitation CReq 1 CReq 4 CReq 2 CReq 3 } Performed at the interface between customer and supplier } Goal is to ensure a common understanding about customer requirements on BOTH sides Copyright © 2017 Neusoft Technology Solutions Gmb. H – Confidential – No Distribution or Copy without prior written approval! CReq 5 CReq n

Implementation and challenges of SYS. 1 Requirements Elicitation } Usually not explicitly assessed by customers } Partly performed intuitively during SYS. 2 System requirements analysis } Recommended participants: system engineer, system architect, domain architects, requirements engineers, tester Challenges: } Resources need to be provided } Customers need to be involved } Commitment for baselined customer requirements is hardly to receive from customer Copyright © 2017 Neusoft Technology Solutions Gmb.

Idea of system processes in Automotive SPICE®: SYS. 2 System Requirements Analysis er m to s Cu t ec j o Pr ! Customer Requirements CReq 1 CReq 4 CReq 2 CReq 3 CReq 5 CReq n System Requirements SYS. 2 System Requirements Analysis Sys. Req 1 Sys. Req 5 Sys. Req 6 Sys. Req 2 Sys. Req 3 Sys. Req 4 } Analyze Customer Requirements and translate them into local technical language, detailing them out } Ensure feasibility and testability Copyright © 2017 Neusoft Technology Solutions Gmb. H – Confidential – No Distribution or Copy without prior written approval! Sys. Req 7 Sys. Req n

Implementation and challenges of SYS. 2 System Requirements Analysis (1/3) } Derive system requirements from: § Internal requirements (e. g. quality, logistic, etc. ) § Cross-cutting technical requirements (“Querschnittslastenhefte”) § Legal requirements § Engineering standards } Recommended participants: system engineer, system tester, requirements engineer, domain experts } Ensure complete coverage of customer requirements Copyright © 2017 Neusoft Technology Solutions Gmb. H – Confidential – No Distribution or Copy without prior written approval!

Implementation and challenges of SYS. 2 System Requirements Analysis (2/3) } Identify “non-requirements” in customer specification: § Information for understanding of requirements § Requirements for architectural design decisions § Tag and map them appropriately (for traceability reasons) } Identify concrete requirements for HW-/SW-/MEC in customer requirements § Analyze impact on system and other domains § Derive system and other domain requirements for them } Will be focus of system qualification test stage (SYS. 5) Copyright © 2017 Neusoft Technology Solutions Gmb. H – Confidential – No Distribution or Copy without prior written approval!

Implementation and challenges of SYS. 2 System Requirements Analysis (3/3) Challenges: } System engineers with experience and overview on system level are often not available } Customer requirements often are not stable while change request management is not implemented yet } Internal requirements are not taken into account for system requirements analysis } Traceability is implemented but consistency is not ensured } Domain specific requirements on system level need to be managed in an appropriate way (see above) } System requirements specification is not updated after changes in later project phases Copyright © 2017 Neusoft Technology Solutions Gmb. H – Confidential – No Distribution or Copy without prior written approval!

Idea of system processes in Automotive SPICE®: SYS. 3 System Architectural Design t ec j o Pr System Requirements Sys. Req 1 Sys. Req 5 Sys. Req 6 Sys. Req 2 Sys. Req 3 Sys. Req 4 Sys. Req 7 Sys. Req n SYS. 3 System Architectural Design } Transform system requirements into architectural solution } Make decisions about distribution of architecture elements and requirements Copyright © 2017 Neusoft Technology Solutions Gmb. H – Confidential – No Distribution or Copy without prior written approval!

Implementation and challenges of SYS. 3 System Architectural Design (1/3) } Map system requirements to architecture elements } Identify decisions for architectural design in customer requirements and map them to system architecture § These decisions will not be part of system requirements } Define interfaces of the system (internal as well as external) } Define dynamic behavior } Ensure complete coverage of system requirements Copyright © 2017 Neusoft Technology Solutions Gmb. H – Confidential – No Distribution or Copy without prior written approval!

Implementation and challenges of SYS. 3 System Architectural Design (2/3) } Architecture sometimes is already predefined (e. g. for platform development) § Structure system requirements according to existing architecture § Existing platform has strong influence on extension of architecture } Definition of architecture may be started in parallel of system requirements analysis § Mind the different approaches (requirements vs. solution) } Is the basis for different domain specifications (SW, HW, MEC) } Will be focus for system integration test stage (SYS. 4) Copyright © 2017 Neusoft Technology Solutions Gmb. H – Confidential – No Distribution or Copy without prior written approval!

Implementation and challenges of SYS. 3 System Architectural Design (3/3) Challenges: } System engineers with experience and overview on system level are often not available } Sometimes architecture needs to be shown to customer in proposal phase } Predefined architecture might limit the margin for decisions } Traceability is implemented but consistency is not ensured Copyright © 2017 Neusoft Technology Solutions Gmb.
