CRD-ESE Organization Step #1: Vision & Mission - Organization

“We develop the right elevator right, the first time” • The 'right elevator': fulfils the stakeholder requirements • The 'elevator right': we deliver a qualified system • The 'first time': limited number of development loops ESE relies on 2 pillars:

- ESE-SE shares and promotes system engineering practices within the CRD organization (Legislative)

- ESE-SD makes use of system engineering best practices to timely provide product lines deliverables to the SPM organization (Executive)

2.2 MBSE Simulation

All load factors simulated And …. Matched against measurements

MBSE is used to provide the sub-systems complete and correct component requirements.

Enablers: MBSE - LBLC © Schindler Apr 2013 | Ph. Henneau | Swiss-VPE 24 Apr 2013

Learnings The method

• What are the deficit? Vision & Mission • What can I change/influence? Mind-set & Organization • What does already exist take it, improve it, share &

promote it (make a story, lobbying & massaging) • What doesn’t exist plan & do it • Make everything available for the organization (e.g: server

infrastructure) including documentation.


SE@Schindler Benefits – What’s next

• Reduction of # loops observed, for real! • Integration with operation: SAP talks LBLC , each

unit calculated

• Motivation! Next steps: • MBSE: link models (LBLC – 3D) • SysML • V&V
