“…It is clear that the availability of open-source systems lowered the entry-barrier for conducting casestudies, however as a community we should not only go for the low-hanging fruit. Consequently, we should move the "in vitro" research out of the labs and into an "in vivo" environment [16]. • Thirdly, we should pay close attention to the newer platforms used by practitioners.…”

On the occasion of the 10th anniversary of the MSR conference, it is a worthwhile exercise to meditate on the past, present and future of our research discipline. Indeed, since the MSR community has experienced a big influx of researchers bringing in new ideas, state-of-the art technology and contemporary research methods it is unclear what the future might bring. In this paper, we report on a text mining exercise applied on the complete corpus of MSR papers to reflect on where we come from; where we are now; and where we should be going. We address issues like the trendy (and outdated) research topics; the frequently (and less frequently) cited cases; the popular (and emerging) mining infrastructure; and finally the proclaimed actionable information which we are deemed to uncover.

“…Millham, for example, uses clustering according to typical dependencies in legacy systems as a similarity measure to cluster objects into component groups representing implementation features [23]. Van Geet and Demeyer [32] apply the technique of Eisenbarth et al [12] which is a mix of static and dynamic analysis. Domain experts create usage scenarios representing features and that would execute the associated code.…”

Reflexion Modelling is an industrially proven and well-established technique for the reconstruction of software architectures. Studies have shown, users of this technique not only envisage it as a means of recovering the logical module structure of the system but also envisage it as a means of modelling a high-level functional view on the system, in which architectural entities represent user-observable functionality. In this case, the challenging task of manual mapping source code to modules in the reflexion model becomes the task of feature location.In this article, we describe the idea of Feature-Oriented Reflexion Modelling in which just-in-time Reflexion Modelling is combined with automatic Feature Location techniques, helping the system expert define that mapping efficiently and thus subsequently analyse, explore, and model the inter-feature dependencies in systems. Feature Location techniques are applied to suggest mapping extensions to the reflexion model to the user, leading to an incremental and interactive mapping process. Furthermore, we outline a research agenda towards an industrially applicable realisation.

Cost‐driven software migration: An experience report

Software migration projects are often bound either by time or cost or by both. If the project is bound by both time and cost, the user must sacrifice something else, usually the quality. The migration strategy depends on how the project is bound. Most migration projects are bound by time. The new system must be in operation by a given date, no matter what it costs. The project described here—a state employee payroll system—is bound by cost. It must remain within the budget, no matter how long it takes. The original costs were estimated based on the code size and the productivity measured in previous migration projects using three different approaches: conversion, redevelopment, and reimplementation. The conversion approach would have been the cheapest, but it had already been tried and failed. The redevelopment approach was considered to be out of the question due to the high costs. Thus, reimplementation remained as the only alternative. The costs of this approach were estimated using three different estimation methods and approved by the state government. The project has been in progress for 4 years, and until now, the estimated costs and actual costs are in the same order of magnitude: the costs have remained within budget. In fact, the costs are less than what was estimated with some methods. As this particular project is not bound by time, it is a good example of continuous migration.
