Capabilities of smart products grouped into four stages Monitoring Control Optimization Autonomy Comprehensive monitoring of product s condition, environment, operation and usage Giving of alerts and notifications of changes Software embedded in the product or in the product cloud for: Control of product functions Personalization of the user experience Optimization of product operation and use through algorithms to: Enhance performance Allow predictive diagnostics, service, and repair Acting autonomous regarding operation, enhancement and personalization Self-coordination of operation with other systems Self-diagnosis Source: Porter and Heppelmann, 2014 Seite 8

Failure rate / Costs per failure Initial situation Shortened product life cycle Shorter and stable development processes Increased competitive pressure Characteristics of smart products Failure appearance and -removal in stagegate product creation process failure appearance failure removal 100,- -,10 1,- 10,- failure cost High complexity of product systems Numerousness of points of intersection through interdisciplinary development Product planning Process planning Requirements Development Production Operating Example from automotive industry: 30-40% of warranty and goodwill costs through failures in concept development. There are major challenges for the development of smart products that affect both the product itself and the process. Source: cf.

Challenges arising from the smart product Data from social media Cloud Field data Suitable application scenarios effective Threat: digital customer mismatch Adaption of product to customer behavior Smart product usability Target characteristic manageable Smart user interfaces (e.g. force feedback) Design of intuitive digital operability Smart defect management faultless / customized Digital multi-functionality: increasing error possibilities Availability of defect information by product intelligence Fields of action for quality management in smart product development Seite 11
Challenges arising from the development process Coordination and cooperation of different disciplines and several development teams Balance between virtual and real prototypes (e.g. out of 3D printers) for product validation Customer integration into product development Measuring product maturity enhancement How is the optimal development process for smart products structured? There are promising agile approaches from software development. Stage gate development processes Agile development processes Pictures: www.chip.de Seite 12
SCRUM as an example for an agile development approach sprint daily scrum product backlog sprint planning sprint backlog product increment user story sprint retrospektive sprint review Scrum is a promising approach for agile development. It is used in software development successfully and smart products include also software. Source: cf. Rubin, 2013 Seite 13
