Flexible Product Line Engineering With a Virtual Platform

1. Flexible Product Line Engineering With a Virtual Platform Michał Antkiewicz NIER Track, ICSE’14 June 5, 2014 http://gsd.uwaterloo.ca http://necsis.ca

3. How novel is the idea presented in this work?

4. “Virtual Platform” is … an incremental and minimally invasivestrategy for adoption of product line engineering

10. “Make the distributed assets reusable instead of integrating them into a platform” Key Idea 1

11. “Offer incremental benefits for incremental efforts” Key Idea 2

12. Virtual Platform = 6 Governance Levels For each level • Description • Advantages • Disadvantages • Tactics • (Example) • Recommendation

13. Governance Levels Frequency of Reuse Preparation Effort L6: PLE with a Fully Integrated Platform L5: PLE with an Integrated Platform and Clone & Own L4: Clone & Own with a Feature Model L3: Clone & Own with Configuration L2: Clone & Own with Features L1: Clone & Own with Provenance L0: Ad-Hoc Clone & Own

14. “Each level is ‘good’ given the specific needs” Key Idea 3

16. To what extent are the new results emerging?

17. "Cloning Considered Harmful" Considered Harmful Kapser and Godfrey, WCRE '06

18. “Integrated Platform not Always Desirable” Dubinsky et al., CSMR, 2013 (Best Paper Award) Stallinger et al., PLEASE, 2011

19. Clone Management Framework Rubin et al., SPLC’12, ICSE NIER’13, SPLC’13 (Best Paper Award)

20. Spawned Research Activities • University of Koblenz-Landau • Managing cloning in 101companies • Measure consequences of lack of the management • University of Waterloo • Embedded feature annotations (FA) • Simulation study to measure cost/benefit of FAs • Virtual Platform Development Tool • IT University of Copenhagen • Variability-aware Version Control

21. What is the potential impact of this work?

22. A roadmap for organizations Justifiable effort / expected benefits Ability to scale up reuse

23. A way to achieve some benefits of PLE by SMEs Feature-oriented development Proactively or retroactively

24. One consultant* applied the governance levels to characterize an organization * DessaultSystemes

25. Another consulting company confirmed the value, the need, and the applicability for its clients Where are the tools?!?
