Measuring Software Process: A Systematic Mapping Study

Context: Measurement is essential to reach predictable performance and high capability processes. It provides support for better understanding, evaluation, management, and control of the development process and project, as well as the resulting product. It also enables organizations to improve and predict its process’s performance, which places organizations in better positions to make appropriate decisions. Objective: This study aims to understand the measurement of the software development process, to identify studies, create a classification scheme based on the identified studies, and then to map such studies into the scheme to answer the research questions. Method: Systematic mapping is the selected research methodology for this study. Results: A total of 462 studies are included and classified into four topics with respect to their focus and into three groups based on the publishing date. Five abstractions and 64 attributes were identified, 25 methods/models and 17 contexts were distinguished. Conclusion: capability and performance were the most measured process attributes, while effort and performance were the most measured project attributes. Goal Question Metric and Capability Maturity Model Integration were the main methods and models used in the studies, whereas agile/lean development and small/medium-size enterprise were the most frequently identified research contexts.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2016-76956-C3-2- RMinisterio de Economía y Competitividad TIN2015-71938-RED

Discovering Business Models for Software Process Management - An Approach for Integrating Time and Resource Perspectives from Legacy Information Systems

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.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-

A metamodel to integrate business processes time perspective in BPMN 2.0

Context: Business Process Management (BPM) is becoming a strategic advantage for organizations tostreamline their operations. Most business experts are betting for OMG Business Process Model and No- tation (BPMN) as de-facto standard (ISO/IEC 19510:2013) and selected technology to model processes. Thetemporal dimension underlies in any kind of process however, technicians need to shape this perspectivethat must also coexist with task control flow aspects, as well as resource and case perspectives. BPMNpoorly gathers temporary rules. This is why there are contributions that extend the standard to coversuch dimension. BPMN is mainly an imperative language. There are research contributions showing timeconstraints in BPMN, such as (i) BPMN patterns to express each rule with a combination of artifacts, thusthese approaches increase the use of imperative BPMN style, and (ii) new decorators to capture timerules semantics giving clearer and simpler comprehensible specifications. Nevertheless, these extensionscannot yet be found in the present standard.Objective: To define a time rule taxonomy easily found in most business processes and look for an ap- proach that applies each rule with current BPMN 2.0 standard in a declarative way.Method: A model-driven approach is used to propose a BPMN metamodel extension to address time- perspective.Results: We look at a declarative approach where new time specifications may overlie the main controlflow of a BPMN process. This proposal is totally supported with current BPMN standard, giving a BPMNmetamodel extension with OCL constraints. We also use AQUA-WS as a software project case study whichis planned and managed with MS Project. We illustrate business process extraction from project plans.Conclusion: This paper suggests to handle business temporal rules with current BPMN standard, alongwith other business perspectives like resources and cases. This approach can be applied to reverse engi- neering processes from legacy databases.Ministerio de Economía y Competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015- 71938-RED

A survey on business processes management suites

Over the last decade, processes have become an important asset for daily life in organizations because an adequate Business Processes Management (BPM) of an organization (e.g. software development companies) can help achieve organizational objectives. Especially, it is important to efficiently manage these processes vital for the organizational performance in order to continually improve, therefore increasing productivity and competitiveness within the organization (e.g. software processes in software companies). This management is associated with the process lifecycle and, at present, there are many tools (Business Process Management Suites, BPMS) for managing this lifecycle. However, all BPMSs do not provide full support for this lifecycle what makes it more difficult to choose the right BPMS (according to the needs of the organization). This paper presents a survey on BPMS highlighting each phase of the process lifecycle what enables organizations to compare specific BPMS according to their own organizational objectives. This survey has been carried out using a methodology that combines systematic literature review with quality models. This methodology has been used successfully in other contexts. Finally, this paper also describes how this survey has been instantiated on specific open source BPMSs.Ministerio de Economía y competitividad TIN2013-46928-C3-3-RMinisterio de Economía y Competitividad TIN2015- 71938-RED

Arthroscopic approach for treating a pigmented villonodular sinovitis of TMJ. A case report

The present report describes the case of a 29-year-old man referred to our service for TMJ pain and progressive reduction of the mouth opening. Differential diagnostics included rheumatologic diseases, monoarthritis and intraarticular lumps. In this line, a face CT scan and a MRI of TMJ were carried out in order to ensure a proper diagnosis. These tests showed a solid lesion into the joint cavity. In view of that, we decided to perform a diagnostic and therapeutic arthroscopy of TMJ. Histopathological studies confirmed the diagnosis of pigmented villonodular synovitis. The main aim of this report is to describe this rare syndrome with the goal of proposing suitable treatments. Moreover, we highlight the benefits of using arthroscopic procedures in the cases which the tumor is still confined to the joint. As far as we are aware, scientific literature documents only a single case of pigmented villonodular synovitis of TMJ treated with arthroscopic approach

Posttraumatic carotid-cavernous fistula: pathogenetic mechanisms, diagnostic management and proper treatment. A case report

Carotid-cavernous fistulas are an uncommon diseases characterized by abnormal communications between arteries and veins located in the cavernous sinus. According with Barrow´s classification they could be divided in two groups: direct and indirect. The typical symptoms showed by theses pathologies are: pulsating exophthalmos and orbital blow. The present study describes a case of direct posttraumatic carotid-cavernous fistula in a 26 years old man. Furthermore, we present the images that we used to make the diagnosis. In this light, we decided to treat this case with endovascular approach after considering several therapeutic options. The aim of the present report is twofold. First, we examine the importance of the proper management of the direct posttraumatic carotid-cavernous fistula. Second, we describe this rare syndrome with the goal of proposing suitable treatments

An association rule mining method for estimating the impact of project management policies on software quality, development time and effort

Accurate and early estimations are essential for effective decision making in software project management. Nowadays, classical estimation models are being replaced by data mining models due to their application simplicity and the rapid production of profitable results. In this work, a method for mining association rules that relate project attributes is proposed. It deals with the problem of discretizing continuous data in order to generate a manageable number of high confident association rules. The method was validated by applying it to data from a Software Project Simulator. The association model obtained allows us to estimate the influence of certain management policy factors on various software project attributes simultaneously

Traumatic arteriovenous fistula as consequence of TMJ arthroscopic surgery: a case report

The ocurrence of a traumatic arteriovenous fistula after arthroscopic surgery of TMJ represents an extremely rare event. Specifically, this uncommon complication has been described only in a few case reports. In this light, the most frequent symptoms showed by this disease are thrills, bruits, pulsatile tinnitus, and an expansible vascular mass. Importantly, the severity of these symptoms is also dependent on the vessels involved. With regard to the management, is important to note that the vessel ligation with surgery as well as vessel emolization with endovascular procedures have been shown to be effective in the treatment of these cases. In view of that, the present study describes a case of superficial temporal arteriovenous fistula that arose as a postoperative complication of a bilateral arthroscopic eminoplasty of TMJ. The aim of the present report is to characterize this rare syndrome with the goal of proposing suitable treatments

Meningitis and subdural empyema as complication of pterygomandibular space abscess upon tooth extraction

Complication of dental infections might be various and heterogeneous. The most common complications are represented by maxilar celulitis, canine space celulitis, infratemporal space celulitis, temporal celulitis and bacteremia. Among rarest complications we found: sepsis, bacterial endocarditis, mediastinitis, intracranial complications, osteomyelitis, etc. Although dental infections are often considered trivial entities, sometimes they can reach an impressive gravity. In this regard, the present study describes a case of dental infection complicated by meningitis, subdural empiema and cerebral vasculitis. Furthermore, we observed other neurological complications, like thalamic ischemic infarction, during the disease evolution. Noteworthy, these entities were not presented when the patient was admitted to hospital. Therefore, the main aim of this report is to highlight the serious consequences that an infection of dental origin could cause
