1 2 3 4 25 Discussions & Conclusions
Limits :
Discussions
• Time of problem statement, data gathering
(still not conventional in enterprises)
• Breakthrough projects are still marginal in enterprises
(Claims about innovation are numerous but avoiding risks and cost reduction still
dominates industry)
• Engineers are marginally trained to TRIZ / Inventive Design
(See ETRIA report on TRIZ world-wide survey – www.etria.net )
Future development directions :
• Build a reliable and continuous partnership with a larger circle of users;
p p g ;
• Research: Assisting experts analyses with data mining procedures
(PatentCrawler);
• Continue to complete the functionalities through networking with a wider circle
of users/funding entities.
