Beginning with the initial evaluationof SRE technology for AT&T’s TeleConference Service De-velopment in 1992, this presentation covers the eventual useof SRE in many phases of software development for twoseparate systems. Introduction of SRE into the system testand production support processes of a legacy system, in con-junction with other development process improvements,brought early rewards in quality and timely delivery. SREprovided a gauge by which quality efforts could be measured.Ramp up time and costs, as well as both successes and failuresin the implementation of SRE are discussed. Next, presenta-tion of preliminary findings regarding the use of SRE duringthe analysis, design, and integration testing phases of a nextgeneration ClientrServer conferencing system are discussed.Reuse of an Operational Profile and SRE tools originallydeveloped and deployed for the legacy system to guide designon a new mixed platform ClientrServer architecture incor-porating a Windows interface and Unix application server isexplained. Lastly, a discussion of the appropriateness of SREmethods for both traditional functional decomposition tech-niques and Object-Oriented analysis and design is offered.Ž .Author abstract In English EI Order Number:EIP98014022054Keywords: Computer aided software engineering; Computersoftware selection and evaluation; Quality assurance; Telecon-ferencing; Computer architecture; UNIX; Object oriented

IEEE Comp Soc,Los Alamitos, CA, USA,97TB100170. p 38-47 CODEN: PSS-RFV ISSN: 1071-9458Publication Year: 1997Abstract: In real-time software, a correct output which is notproduced within a specified response time interval constitutesa failure. The detection of response times failures is done by aseparate unit which observes the inputs and outputs of thetarget software. Automatic detection of such failures is com-plicated by state dependencies which require the unit to tracka target’s state as well as the elapsed times between specifiedstimulus and response pairs. A novel, black-box approach isdescribed for detecting response time failures and quality ofservice degradations of session-oriented, real-time software.16 Refs.

Title: PREDICTING FAULT-PRONE MODULES WITHCASE-BASED REASONING

IEEE Comp Soc,Los Alamitos, CA, USA,97TB100170. p 27-35 CODEN: PSS-RFV ISSN: 1071-9458Publication Year: 1997Abstract: Software quality classification models seek to predictquality factors such as whether a module will be fault-prone,

Ž .or not. Case-based reasoning CBR is a modeling techniquethat seeks to answer new questions by identifying similar‘cases’ from the past. When applied to software reliability, theworking hypothesis of our approach is this: a module currentlyunder development is probably fault-prone if a module withsimilar product and process attributes in an earlier releasewas fault-prone. The contribution of this paper is applicationof case-based reasoning to software quality modeling. To thebest of our knowledge, this is the first time that case-basedreasoning has been used to identify fault-prone modules. Acase study illustrates our approach and provides evidence thatcase-based reasoning can be the basis for useful softwarequality classification models that are competitive with dis-criminant models. The case study revisits data from a previ-ously published nonparametric discriminant analysis study.The Type II misclassification rate of the CBR model was

may be difficult and reliability predictions can be misleading.Nevertheless statistical methods can be successfully applied tofailure data. This paper presents an approach which allows thedetection of unreliable software components and the compar-ison of the reliability of different software versions - even iftesting is done in a classical manner.

ISA, Research Triangle Park, NC, USA. p143-150 CODEN: 002744 ISSN: 1054-0032Publication Year: 1997Abstract: If ‘information is the currency of the informationage’, then your Fieldbus field devices like transmitters andpositioners are your printing presses. Fieldbus based controlsystems communicate not only process variables, but also lotsof non-control information. Detailed device self-diagnosticsand automatic failure alarms enables quick determination if aprocess problem is due to the sensor or not, without having todo several field visits. The time that can be saved by nothaving to bring only a few transmitters in to the workshop isenormous. Wear and tear data, exceeded operating conditionsor other abnormal behaviour information may be used forpredictive maintenance scheduling minimizing costly unsched-uled downtime. Field instrument management software willcomplement the basic process control function and reducespaper work and enables automatic record keeping and docu-mentation of configuration, calibration and maintenance. Thisis an important feature to help comply with ISO9000 andISO14000 and other quality and environmental managementsystem requirements for updated and traceable records. Field-bus helps companies increase productivity, flexibility, qualityand comply with ever more stringent environmental regula-tions, and at the same time lower their operating cost. Field-bus is the means whereby companies will stay competitive well
