OORTs a family of reading techniques that can be used to inspect object oriented high level design Oort, Jan Hendrik (1900-1992), Dutch astronomer, noted for his determination that the earth's galaxy, the Milky Way, rotates, and for his contributions to comet theory. Born in Franeker, he was educated at the University of Groningen. Associated with the Leiden University and its observatory, Oort, with his colleagues, established the Milky Way's rotation in the 1920s; they also worked out the mass of the galaxy and the distance of its center from the sun. Oort pioneered in Dutch radio astronomy. He proposed in 1950 that a cloud of cometary material surrounds the solar system at an enormous distance, a concept now generally accepted.

H. Travassos

ISERN 2001 presentation UFRJ COPPE Project Status A set of 7 techniques incorporating modifications to deal with all problems revealed by the experiments is available Data from last experiment (Spring 2000) is still under analysis techniques used to inspect and support system evolution (maintenance) techniques used in the context of a full software process Experiment has been replicated at NTNU (Observational Study using a modified version of OORTs) An experiment regarding the application of reading techniques in different development contexts has been accomplished in Brazil (first semester 2001). Data is under analysis. Some papers describing the techniques and the experimentation process were published (OOPSLA, NASA/SEL Workshop, Advances in Computers vol. 54, ESEC/FSE, Technical Reports, ...) G. H.

A Collaborative Research to Develop, Validate and Package Reading Techniques for Software Defect Detection Team: Jos C. Maldonado- University of So Paulo Victor Basili, Jeffrey Carver - UM/ESEG Sandra Fabri - UFSCar Manoel Mendona - UNIFACS Guilherme H. Travassos COPPE/UFRJ Forrest Shull Fraunhofer/Maryland This research focus on developing techniques to analyze software documents for defect detection. More specifically, mutation testing and document reading techniques will be tailored to detect defects in software formal specifications and source code at Brazilian and American academia and industries. This family of software analysis technologies will be empirically validated in controlled experiments, and packaged in tailorable and reusable software engineering laboratory UFRJ packages. G. H. Travassos ISERN 2001 presentation COPPE A Comprehensive Reuse Model For COTS Team:

Daniil Yakimovich, Victor Basili UM/ESEG G. H. Travassos COPPE/UFRJ To justify the use of a commercial off-the-shelf (COTS) product in software development, one must evaluate the cost of using the product, i.e. integrating it into the requirements. Ideally, this should take place during the COTS selection phase, i.e., the estimated cost of integration should be a factor in COTS selection. Thus, our goal is to design characterization schemes that would allow us to describe integration requirements for COTS products and evaluate them in the context of the system to be built. Then a COTS reuse process including evaluation, integration and the necessary additional activities must be defined. G. H. Travassos ISERN 2001 presentation UFRJ COPPE Project Status An experiment (case study) was planned and executed to evaluate the feasibility of such model Some results heuristics to guide the identification and classification of COTS integration mismatches model seems to be useful, mainly for developers with medium level of expertise improvements in the model to capture pseudo incompatibilities (e.g. training effort)

This information will reside in a web-based and thus distributed Experience Library. G. H. Travassos
