Software process lines (SPrL) are families of highly related processes that are built from a set of core process assets. Software companies can use SPrLs to address the development of different types of projects – development or maintenance, large or small, complex or simple – and therefore reuse process knowledge in an organized way. This can be achieved by either defining a series of processe...

Software process lines (SPrL) are families of related processes, built from a set of administrated software process elements in a prestablished fashion, similar to how software product lines (SPL) are built with software assets. In SPLs, variability is usually speci ed using feature models. As SPrLs manage particular kinds of process elements, namely tasks, roles and work products, we explore t...

In many processes in real practice at the start-up stages the process parameters are not known a priori and there are no initial samples or data for executing Phase I monitoring and estimating the process parameters. In addition, the practitioners are interested in using one control chart instead of two or more for monitoring location and variability of processes. In this paper, we consider a s...

Degradation modeling requires to consider the complexity of both internal structure highly reliable products and environmental conditions, define appropriate models obtain estimations about reliability quality. These conditions reflect different sources variability that need be considered in aims obtaining accurate estimations. Although several have been proposed literature, few them simultaneo...
