PHMs facilitate the merging of two research directions that have to a large extent developed independently-defect modeling based on software static analyses and reliability growth modeling based on dynamic assumptions about the software failure process. Determinants of software reliability include a composite measure of software complexity, software development volatility as measured by non-defect changes, and cumulative testing effort. A PHM is developed using execution time-between-failure data for a collection of subsystems from two software projects. The PHM analysis yields non-parametric estimates of the baseline hazard functions for each of the projects and parametric estimates of the determinants of software reliability. Weibull curves are shown to provide a good fit to the non-parametric estimates of the baseline hazard functions. These curves are used to extrapolate the non-parametric estimates for times between failure to infinity in order to compute the mean time between failures. Failure curves are generated for each of the subsystems as a function of the cumulative project execution times and summed over the subsystems to obtain project failures vs. cumulative project execution times. These estimated project failure curves track the empirical project failure curves quite well. Project failure curves estimated for the case when no non-defect changes are made show that in excess of 50% of failures can be attributed to non-defect changes.","PeriodicalId":254605,"journal":{"name":"STEP '99.

As a consequence the integration of IT systems into organisations, and in particular the subsequent exploitation and operation support activities, have become of utmost importance. The area of IT exploitation and operation is known as Service Management and covers activities such as performance and availability support, end-user and help desk support, education, and technical operation. One of the main concepts of Service Management is the Service Level Agreement (SLA). The purpose of a SLA has recently shifted from being a financial contract towards an instrument for the management of the customer's expectations. Managing customer's expectations is based on the definition of services, the specification of service levels agreements and the design and implementation of service processes. This paper presents the underlying concepts for the identification and specification of Service Level Agreements. Based on lessons learned from empirical research a description and clarification is given of these SLA concepts.","PeriodicalId":254605,"journal":{"name":"STEP '99.
