DIB An Example of Experience Factory from Bari University 1 An Experience of Technologies Diffusion Prof. Giuseppe Visaggio Department of Computer Science University of Bari

DIB An Example of Experience Factory from Bari University 2 SETTING /The research and experience packaging were carried out in Software Engineering Research Laboratory (SER-Lab) /Domains dealt with: êrenewal processes for geriatric software êmonitoring of software decay

DIB An Example of Experience Factory from Bari University 3 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.

DIB An Example of Experience Factory from Bari University 4... 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.

DIB An Example of Experience Factory from Bari University 10 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. /Templates for application architectures with a good level of information hiding.

DIB An Example of Experience Factory from Bari University 11 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.

DIB An Example of Experience Factory from Bari University 12 RCV : Reused Packages /Aging symptoms, the metrics were adapted /Decision Model for defining the renewal process adequate to age symptoms. /Reengineering process was suggested. The management is considering its decision.

DIB An Example of Experience Factory from Bari University 13 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.

DIB An Example of Experience Factory from Bari University 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).

DIB An Example of Experience Factory from Bari University 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).
