10 Software Development Concerns BAPO The way to make profit from the resulting products plan the family scope based upon profit expectations economical analysis of family development reuse economics The technology needed to build systems B Business design for reuse & diversity advantages and drawbacks of variation mechanisms product development based on an asset repository A Architecture P Process O Organisation Organisational structures and responsibilities during development relationships between family and product development groups management responsibilities Activities and dependencies during development separation of family and product activities asset management feedback loops

11 CAFÉ Market Impact Functionality Integration in the strategic planning process Tactical Development (Application Driven) Market Requirements Surface indicates effort Application development Family development Market pressure Strategic Development (Domain Driven) Total development per product Economic bene- fits of family development t 1 t 2 t 3 Time

23 Software Einzelentwicklung vs. Software Produktfamilienentwicklung Grundsätzlich anderer Ansatz der Entwicklung: Einzelne Produkte Mehrere / viele Produkte Einzelne Projekte Mehrere / viele Projekte Produktentwicklung Ableitung von Produkten aus einer Plattform durch Instanzieren von Variabilitäten Entwicklung einer Plattform mit wiederverwendbaren Assets Ein Kernprozess Zwei Kern-Subprozesse (Domain- und Application Engineering)

24 Unterschied Produktfamilien und Wiederverwendung Berücksichtigung des ganzen Lebenszyklus Planung der Produkte und ihrer Features Analyse der Gemeinsamkeiten und Unterschiede Wiederverwendung genau im Rahmen der Planung Berücksichtigung ökonomischer und organisatorischer Aspekte Alle Assets können wiederverwendet werden

25 Kernthemen des Produktfamilien-Engineering Commonality & Variability: Produktplanung: C&V in Features Requirements Engineering: C&V in Requirements Architektur: C&V in Architekturbausteinen Design: C&V in Designbausteinen Implementierung: C&V in Komponenten Test: C&V in Testfällen Wartung: Nutzung von C&V für unterschiedliche Produkte Regel: Gemeinsamkeiten nur ein mal modellieren und entwickeln, aber für alle Produkte nutzen Variabilitäten generell, für alle Produkte gemeinsam modellieren, aber jeweils produktspezifisch binden

26 Schlussbemerkungen In ESAPS und CAFÉ wurden sehr viele Prozesse, Methoden, Techniken für Produktfamilien-Engineering entwickelt Anwendungen in vielen Domänen Wird als der beste Ansatz zur Entwicklung softwareintensiver Systeme gesehen: in Zukunft soll die meiste Software in Familien entwickelt werden Ergebnisse können abgeholt werden unter: ESAPS: CAFÉ:
