Aquisição de serviços de TI como um processo de qualidade no fornecimento de software - estudo de caso de terceirização em medicina transfusional

Face às dimensões continentais do país, as organizações situadas em regiões carentes de fornecedores de desenvolvimento de sistemas de software especializado estão distribuindo suas operações de Information Technology Outsourcing (ITO), para outras regiões. Como consequência, a redução de custos e a melhoria da contratação de serviços em Tecnologia da Informação (TI) têm sido os dois grandes focos da atualidade, incentivando à noção de parceiros múltiplos em operações recíprocas e engajados tanto em relacionamentos formais quanto informais como a terceirização. Os serviços terceirizados são diversificados e entre eles está o desenvolvimento e manutenção de software através de contratos, realizados por organizações situadas em regiões onde existe demanda de software com características específicas. Sabe-se que a terceirização de Software e Serviços Correlatos (S&SC), que inclui as atividades de contratação e gestão do processo de aquisição é uma tarefa complexa e necessária para as organizações, principalmente no que diz respeito às condições envolvidas na contratação. Nesses casos, o exercício da governança tem sido um importante instrumento para, com a terceirização de TI, promover a gestão adequada do risco e o retorno do investimento. Sendo assim, o processo de compra ou venda de um produto de software nesse ambiente é uma atividade que envolve um grande número de conceitos subjetivos, referentes principalmente a características dos produtos. Torna-se maior o desafio quando se trata de software de prateleira modificável (Modified Off-The-Shelf - MOTS) que sofrem modificações e adições de requisitos a cada novo cliente. Neste contexto, buscando adequar as exigências do mercado com as necessidades de métodos e diretrizes para melhoria dos processos de aquisição e fornecimento de software, este trabalho procura explorar as principais características acerca do contrato, do controle de qualidade, e os resultados dos relacionamentos adotados na implementação de projetos de terceirização desenvolvidos á distância. São apresentados os resultados obtidos de um estudo de caso conduzido em uma empresa pública de Medicina Transfusional situada no norte do Brasil que adotou este processo. Por fim, este texto apresenta uma discussão sobre os diferenciais e limitações deste trabalho, e apresenta direcionamentos para investigações futuras neste campo de estudo.

Hardware and software development of a multichannel readout board named CARLOSrx for the ALICE experiment

ALICE, that is an experiment held at CERN using the LHC, is specialized in analyzing lead-ion collisions. ALICE will study the properties of quarkgluon plasma, a state of matter where quarks and gluons, under conditions of very high temperatures and densities, are no longer confined inside hadrons. Such a state of matter probably existed just after the Big Bang, before particles such as protons and neutrons were formed. The SDD detector, one of the ALICE subdetectors, is part of the ITS that is composed by 6 cylindrical layers with the innermost one attached to the beam pipe. The ITS tracks and identifies particles near the interaction point, it also aligns the tracks of the articles detected by more external detectors. The two ITS middle layers contain the whole 260 SDD detectors. A multichannel readout board, called CARLOSrx, receives at the same time the data coming from 12 SDD detectors. In total there are 24 CARLOSrx boards needed to read data coming from all the SDD modules (detector plus front end electronics). CARLOSrx packs data coming from the front end electronics through optical link connections, it stores them in a large data FIFO and then it sends them to the DAQ system. Each CARLOSrx is composed by two boards. One is called CARLOSrx data, that reads data coming from the SDD detectors and configures the FEE; the other one is called CARLOSrx clock, that sends the clock signal to all the FEE. This thesis contains a description of the hardware design and firmware features of both CARLOSrx data and CARLOSrx clock boards, which deal with all the SDD readout chain. A description of the software tools necessary to test and configure the front end electronics will be presented at the end of the thesis.

Towards model driven software development for Arduino platforms: a DSL and automatic code generation

La tesi ha lo scopo di esplorare la produzione di sistemi software per Embedded Systems mediante l'utilizzo di tecniche relative al mondo del Model Driven Software Development. La fase più importante dello sviluppo sarà la definizione di un Meta-Modello che caratterizza i concetti fondamentali relativi agli embedded systems. Tale modello cercherà di astrarre dalla particolare piattaforma utilizzata ed individuare quali astrazioni caratterizzano il mondo degli embedded systems in generale. Tale meta-modello sarà quindi di tipo platform-independent. Per la generazione automatica di codice è stata adottata una piattaforma di riferimento, cioè Arduino. Arduino è un sistema embedded che si sta sempre più affermando perché coniuga un buon livello di performance ed un prezzo relativamente basso. Tale piattaforma permette lo sviluppo di sistemi special purpose che utilizzano sensori ed attuatori di vario genere, facilmente connessi ai pin messi a disposizione. Il meta-modello definito è un'istanza del meta-metamodello MOF, definito formalmente dall'organizzazione OMG. Questo permette allo sviluppatore di pensare ad un sistema sotto forma di modello, istanza del meta-modello definito. Un meta-modello può essere considerato anche come la sintassi astratta di un linguaggio, quindi può essere definito da un insieme di regole EBNF. La tecnologia utilizzata per la definizione del meta-modello è stata Xtext: un framework che permette la scrittura di regole EBNF e che genera automaticamente il modello Ecore associato al meta-modello definito. Ecore è l'implementazione di EMOF in ambiente Eclipse. Xtext genera inoltre dei plugin che permettono di avere un editor guidato dalla sintassi, definita nel meta-modello. La generazione automatica di codice è stata realizzata usando il linguaggio Xtend2. Tale linguaggio permette di esplorare l'Abstract Syntax Tree generato dalla traduzione del modello in Ecore e di generare tutti i file di codice necessari. Il codice generato fornisce praticamente tutta la schematic part dell'applicazione, mentre lascia all'application designer lo sviluppo della business logic. Dopo la definizione del meta-modello di un sistema embedded, il livello di astrazione è stato spostato più in alto, andando verso la definizione della parte di meta-modello relativa all'interazione di un sistema embedded con altri sistemi. Ci si è quindi spostati verso un ottica di Sistema, inteso come insieme di sistemi concentrati che interagiscono. Tale difinizione viene fatta dal punto di vista del sistema concentrato di cui si sta definendo il modello. Nella tesi viene inoltre introdotto un caso di studio che, anche se abbastanza semplice, fornisce un esempio ed un tutorial allo sviluppo di applicazioni mediante l'uso del meta-modello. Ci permette inoltre di notare come il compito dell'application designer diventi piuttosto semplice ed immediato, sempre se basato su una buona analisi del problema. I risultati ottenuti sono stati di buona qualità ed il meta-modello viene tradotto in codice che funziona correttamente.

Engineering Agent-Oriented Technologies and Programming Languages for Computer Programming and Software Development

Mainstream hardware is becoming parallel, heterogeneous, and distributed on every desk, every home and in every pocket. As a consequence, in the last years software is having an epochal turn toward concurrency, distribution, interaction which is pushed by the evolution of hardware architectures and the growing of network availability. This calls for introducing further abstraction layers on top of those provided by classical mainstream programming paradigms, to tackle more effectively the new complexities that developers have to face in everyday programming. A convergence it is recognizable in the mainstream toward the adoption of the actor paradigm as a mean to unite object-oriented programming and concurrency. Nevertheless, we argue that the actor paradigm can only be considered a good starting point to provide a more comprehensive response to such a fundamental and radical change in software development. Accordingly, the main objective of this thesis is to propose Agent-Oriented Programming (AOP) as a high-level general purpose programming paradigm, natural evolution of actors and objects, introducing a further level of human-inspired concepts for programming software systems, meant to simplify the design and programming of concurrent, distributed, reactive/interactive programs. To this end, in the dissertation first we construct the required background by studying the state-of-the-art of both actor-oriented and agent-oriented programming, and then we focus on the engineering of integrated programming technologies for developing agent-based systems in their classical application domains: artificial intelligence and distributed artificial intelligence. Then, we shift the perspective moving from the development of intelligent software systems, toward general purpose software development. Using the expertise maturated during the phase of background construction, we introduce a general-purpose programming language named simpAL, which founds its roots on general principles and practices of software development, and at the same time provides an agent-oriented level of abstraction for the engineering of general purpose software systems.

Understanding the Combined Role of Internal and External Factors in New Service Development Process within the Professional Knowledge Intensive Business Service Firms

Our research asked the following main questions: how the characteristics of professionals service firms allow them to successfully innovate in exploiting through exploring by combining internal and external factors of innovation and how these ambidextrous organisations perceive these factors; and how do successful innovators in professional service firms use corporate entrepreneurship models in their new service development processes? With a goal to shed light on innovation in professional knowledge intensive business service firms’ (PKIBS), we concluded a qualitative analysis of ten globally acting law firms, providing business legal services. We analyse the internal and factors of innovation that are critical for PKIBS’ innovation. We suggest how these firms become ambidextrous in changing environment. Our findings show that this kind of firms has particular type of ambidexterity due to their specific characteristics. As PKIBS are very dependant on its human capital, governance structure, and the high expectations of their clients, their ambidexterity is structural, but also contextual at the same time. In addition, we suggest 3 types of corporate entrepreneurship models that international PKIBS use to enhance innovation in turbulent environments. We looked at how law firms going through turbulent environments were using corporate entrepreneurship activities as a part of their strategies to be more innovative. Using visual mapping methodology, we developed three types of innovation patterns in the law firms. We suggest that corporate entrepreneurship models depend on successful application of mainly three elements: who participates in corporate entrepreneurship initiatives; what are the formal processes that enhances these initiatives; and what are the policies applied to this type of behaviour.

The Scrum approach to software development

Agile methodologies have become the standard approach to software development. The most popular and used one is Scrum. Scrum is a very simple and flexible framework that respond to unpredictability in a really effective way. However, his implementation must be correct, and since Scrum tells you what to do but not how to do it, this is not trivial. In this thesis I will describe the Scrum Framework, how to implement it and a tool that can help to do this. The thesis is divided into three parts. The first part is called Scrum. Here I will introduce the framework itself, its key concepts and its components. In Scrum there are three components: roles, meetings and artifacts. Each of these is meant to accomplish a series of specific tasks. After describing the “what to do”, in the second part, Best Practices, I will focus on the “how to do it”. For example, how to decide which items should be included in the next sprint, how to estimate tasks, and how should the team workspace be. Finally, in the third part called Tools, I will introduce Visual Studio Online, a cloud service from Microsoft that offers Git and TFVC repositories and the opportunity to manage projects with Scrum. == Versione italiana: I metodi Agile sono diventati l’approccio standard per lo sviluppo di software. Il più famoso ed utilizzato è Scrum. Scrum è un framework molto semplice e flessibile che risponde ai cambiamenti in una maniera molto efficace. La sua implementazione deve però essere corretta, e visto che Scrum ci dice cosa fare ma non come farlo, questo non risulta essere immediato. In questa tesi descriverò Scrum, come implementarlo ed uno strumento che ci può aiutare a farlo. La tesi è divisa in tre parti. La prima parte è chiamata Scrum. Qui introdurrò il framework, i suoi concetti base e le sue componenti. In Scrum ci sono tre componenti: i ruoli, i meeting e gli artifact. Ognuno di questi è studiato per svolgere una serie di compiti specifici. Dopo aver descritto il “cosa fare”, nella seconda parte, Best Practices, mi concentrerò sul “come farlo”. Ad esempio, come decidere quali oggetti includere nella prossima sprint, come stimare ogni task e come dovrebbe essere il luogo di lavoro del team. Infine, nella terza parte chiamata Tools, introdurrò Visual Studio Online, un servizio cloud della Microsoft che offre repository Git e TFVC e l’opportunità di gestire un progetto con Scrum.

Bioconductor: Open software development for computational biology and bioinformatics

The Bioconductor project is an initiative for the collaborative creation of extensible software for computational biology and bioinformatics. We detail some of the design decisions, software paradigms and operational strategies that have allowed a small number of researchers to provide a wide variety of innovative, extensible, software solutions in a relatively short time. The use of an object oriented programming paradigm, the adoption and development of a software package system, designing by contract, distributed development and collaboration with other projects are elements of this project's success. Individually, each of these concepts are useful and important but when combined they have provided a strong basis for rapid development and deployment of innovative and flexible research software for scientific computation. A primary objective of this initiative is achievement of total remote reproducibility of novel algorithmic research results.
