“…For instance, when mainframe systems started to age, but could not be easily replaced, middleware technologies emerged. These then offered alternatives to full-blown and dramatic migration, by allowing old legacy systems to be wrapped in newer software (Bennet 1995;Bisbal et al 1999). While this allowed short-term problem solving, it also contributed to the survival of the legacy systems and thus caused today=s heterogeneous systems portfolios.…”

Abstract. In this paper, I argue that we should not only orient ourselves to the future by looking forward to the yet unrealized. When researching the future, we should also develop a sensibility to the durability of our past and present creations, and understand how they impact the scope for future innovations. The common emphasis on the visionary and novel components of innovation needs to be complemented with an emphasis on the constants, the slowly changing or non-changing aspects. In the paper, I seek to articulate how we could increase our ability to recognize the durability of the present with respect to empirical study objects, analytic approaches, and theoretical resources.

“…Finally, LIS maintenance can be too expensive because these systems are not always well documented. Additionally, if they are highly complex, they are not easy to replace for a new system (Bisbal et al, 1999), (Heuvel, 2006). OMG Architecture-Driven Modernization (ADM) (Ulrich & Newcomb, 2010) is an approach based on MDA that identifies metamodels and processes for LIS modernization.…”

“…Managing all these complex organizational factors simultaneously is seemed as a big challenge. Even though most of these Legacy Information Systems (LIS) (Bisbal et al, 1999) are not BPM-oriented, we need to use this new approach for viewing them as new business models composed of a set of integrated processes. A BPM model will offer interoperability among different systems.…”

Abstract:Business Process Management (BPM) is becoming the modern core to support business in all type of organizations and software business is not an exception. Software companies are often involved in important and complex collaborative projects carried out by many stakeholders. Each actor (customers, suppliers or government instances, among others) works with individual and shared processes. Everyone needs dynamic and evolving approaches for managing their software projects lifecycle. Nevertheless, many companies still use systems that are out of the scope of BPM for planning and control projects and managing enterprise content (Enterprise Content Management, ECM) as well as all kinds of resources (ERP). Somehow systems include scattered artifacts that are related to BPM perspectives: control and data flow, time, resource and case, for example. It is aimed to get interoperable BPM models from these classical Legacy Information Systems (LIS). Model-Driven Engineering (MDE) allows going from application code to higher-level of abstraction models. Particularly, there are standards and proposals for reverse engineering LIS. This paper illustrates LIS cases for software project planning and ECM, looking at time and resource perspectives. To conclude, we will propose a MDE-based approach for taking out business models in the context of software process management.

“…The first concerns the collect of objective measures, which in some cases require modifications in the source code. In these situations, it is not always possible or desirable to alter an application, due to the complexity of the system [2] or the limited availability of development time [28]. The second problem concerns the reliability of subjective metrics, which may have influenced their results by external factors to the interaction process, such as user's physical and mental efforts, or user's cognitive mediation, such as omission or summarization of information.…”

Abstract. This project aims to present a methodology to study the relationships between physiological measures and evaluation metrics for 3D interaction techniques using methods for multivariate data analysis. Physiological responses, such as heart rate and skin conductance, offer objective data about the user stress during interaction. This could be useful, for instance, to evaluate qualitative aspects of interaction techniques without relying on solely subjective data. Moreover, these data could contribute to improve task performance analysis by measuring different responses to 3D interaction techniques. With this in mind, we propose a methodology that defines a testing protocol, a normalization procedure and statistical techniques, considering the use of physiological measures during the evaluation process. A case study comparison between two 3D interaction techniques (ray-casting and HOMER) shows promising results, pointing to heart rate variability, as measured by the NN50 parameter, as a potential index of task performance. Further studies are needed in order to establish guidelines for evaluation processes based on welldefined associations between human behaviors and human actions realized in 3D user interfaces.
