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)

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
