Modeling the object-oriented software process: OPEN and the unified process
A short introduction to software process modeling is presented, particularly object-oriented modeling. Two major industrial process models are discussed: the OPEN model and the Unified Process model. In more detail, the quality assurance in the Unified Process tool (formally called Objectory) is reviewed
Goals/questions/metrics method and SAP implementation projects
During the last years some researchers have studied the critical success factors (CSFs) in ERP implementations.
However, until now, no one has studied how these CSFs should be put in practice to help organizations achieve success
in ERP implementations. This technical research report attempts to define the usage of Goals/Questions/Metrics (GQM)
approach in the definition of a measurement system for ERP implementation projects. GQM approach is a mechanism for
defining and interpreting operational, measurable goals. Lately, because of its intuitive nature the approach has
gained widespread appeal. We present a metrics overview and a description of GQM approach. Then we provide an example
of GQM application for monitoring sustained management support in ERP implementations. Sustained management support
is the most cited critical success factor in ERP implementation projects.Postprint (published version

Legacy Information Systems, Can They be Agile? A Framework for Assessing Agility
Information systems should contribute to enterprise effectiveness, and usually do so during the operational phase of their lifecycle. From the experience of practitioners, the duration of this lifecycle is often not predetermined, therefore resulting in information systems with a relatively long lifespan and information systems with a relatively short lifespan. An important aspect of application management, is managing the application lifecycle. In the experience of practitioners, deciding the moment to end the lifecycle, refactor it, or leave it be are often not thoroughly researched. The decision to move on to a newer information system is therefore not always sufficiently justified and relies more on a gut feeling. What if the older information system is still able to perform and comply with the changes the enterprise desires? Prolonging the length of an application lifecycle could result in cost reduction in an application portfolio. In this paper, we aim to create a method of assessment of the ability to change of a legacy information system and identifying potential areas in which a legacy information system would need improvement in order to increase this ability to change
Software Measurement Activities in Small and Medium Enterprises: an Empirical Assessment
An empirical study for evaluating the proper implementation of measurement/metric programs in software companies in one area of Turkey is presented. The research questions are discussed and validated with the help of senior software
managers (more than 15 years’ experience) and then used for interviewing a variety of medium and small scale software companies in Ankara. Observations show that there is a
common reluctance/lack of interest in utilizing measurements/metrics despite the fact that they are well known in the industry. A side product of this research is that internationally recognized standards such as ISO and CMMI are pursued if they are a part of project/job
requirements; without these requirements, introducing those standards to the companies remains as a long-term target to increase quality

Creative professional users musical relevance criteria
Although known item searching for music can be dealt with by searching metadata using existing text search techniques, human subjectivity and variability within the music itself make it very difficult to search for unknown items. This paper examines these problems within the context of text retrieval and music information retrieval. The focus is on ascertaining a relationship between music relevance criteria and those relating to relevance judgements in text retrieval. A data-rich collection of relevance judgements by creative professionals searching for unknown musical items to accompany moving images using real world queries is analysed. The participants in our observations are found to take a socio-cognitive approach and use a range of content and context based criteria. These criteria correlate strongly with those arising from previous text retrieval studies despite the many differences between music and text in their actual content
A Model-Driven Approach for Business Process Management
The Business Process Management is a common mechanism recommended by a high number of standards for the management of companies and organizations. In software companies this practice is every day more accepted and companies have to assume it, if they want to be competitive. However, the effective definition of these processes and mainly their maintenance and execution are not always easy tasks. This paper presents an approach based on the Model-Driven paradigm for Business Process Management in software companies. This solution offers a suitable mechanism that was implemented successfully in different companies with a tool case named NDTQ-Framework.Ministerio de Educación y Ciencia TIN2010-20057-C03-02Junta de Andalucía TIC-578
Eco‐Holonic 4.0 Circular Business Model to Conceptualize Sustainable Value Chain Towards Digital Transition
The purpose of this paper is to conceptualize a circular business model based on an Eco-Holonic Architecture, through the integration of circular economy and holonic principles. A conceptual model is developed to manage the complexity of integrating circular economy principles, digital transformation, and tools and frameworks for sustainability into business models. The proposed architecture is multilevel and multiscale in order to achieve the instantiation of the sustainable value chain in any territory. The architecture promotes the incorporation of circular economy and holonic principles into new circular business models. This integrated perspective of business model can support the design and upgrade of the manufacturing companies in their respective industrial sectors. The conceptual model proposed is based on activity theory that considers the interactions between technical and social systems and allows the mitigation of the metabolic rift that exists between natural and social metabolism. This study contributes to the existing literature on circular economy, circular business models and activity theory by considering holonic paradigm concerns, which have not been explored yet. This research also offers a unique holonic architecture of circular business model by considering different levels, relationships, dynamism and contextualization (territory) aspects
