SETTING
The research and experience packaging were carried out in Software Engineering Research Laboratory (SER-Lab)
Domains dealt with:renewal processes for geriatric softwaremonitoring of software decay

Transfer Strategy ...
Commitment. New technologies and methods are found efficacious for a risky situation.They are introduced, either in a pilot or a challenging project, and validated by experimentation.

... Transfer Strategy
Packaging and dissemination.The innovative technologies are packaged, together with empirically-gained experience.The best practices are disseminated to other customers in the same or other organizations. New experience can then be included in the package to enhance its reuse potential in future projects.

CHARTRE: Reused Packages
Value Model for technical-economic evaluation of the system, metrics used and baselines were adapted. This model will be used for Quality Monitoring.

FILANTO: Reused Packages
Aging symptoms, the metrics were adapted.Decision Models for defining the renewal
process adequate to age symptoms.Reengineering process was suggested. This
suggestion was not accepted.

RCV : Reused Packages
Aging symptoms, the metrics were adaptedDecision Model for defining the renewal
process adequate to age symptoms.Reengineering process was suggested. The
management is considering its decision.

CONCLUSIONS ...
The experience package needs to be adapted, especially when it has an impact on already active processes. At any reuse, the metric plan had to be adapted.

... CONCLUSIONS ...
The customer management prefers to use packaged experience when the evidence is carefully earned. (RCV and FILANTO decide against the reengineering process although it has been shown to be the most efficacious).

... CONCLUSIONS
Even when innovative technologies have the evidence of their efficacy, they are adopted when the problem has an economic value that is grater then the risk of technology adoption. (Only the value model used for quality monitoring was used after the end of the project in CHARTRE).
