The Design of a Software Lifecycle Management Framework to a Configuration Management System

Keeping track of software assets and managing software installations in IT environments can be a hard endeavor, especially when the size and diversity of the environment grows. How to install and uninstall software efficiently and cost effectively? Are there too few or too many software licenses purchased? If installed, is the software actually in use? Software Asset Management (SAM) is a process that involves managing and optimizing the purchase, deployment, maintenance, utilization, and disposal of software applications within an organization. This master’s thesis describes a special Software Lifecycle Management Framework to provide solutions to the multitude of challenges within SAM. The main objectives when designing the framework was to provide a set of tools to control the software assets during their entire lifecycle while trying to minimize the costs related to owning and managing them.

Proposal of an On-demand Software Deployment System Based on Application Streaming, Virtualization Techniques and P2P Transport

This paper presents the work in progress of an on-demand software deployment system based on application virtualization concepts which eliminates the need of software installation and configuration on each computer. Some mechanisms were created, such as mapping of utilization of resources by the application to improve the software distribution and startup; a virtualization middleware which give all resources needed for the software execution; an asynchronous P2P transport used to optimizing distribution on the network; and off-line support where the user can execute the application even when the server is not available or when is out of the network. © Springer-Verlag Berlin Heidelberg 2010.

Varasto- ja hankintamodulin kehittäminen toiminnanohjausjärjestelmään

Tässä diplomityössä tarkoituksena on kerätä yhteen toiminnanohjausjärjestelmän varasto- ja hankintamodulin kehittämisessä tarvittavaa teoriatietoa, sekä Nestix Oy:n asiakkaiden ja joidenkin muiden yritysten tarpeita kyseiselle ohjelmistolle. Teoria ja tarpeet yhdistetään karkeaksi ohjelmiston tarvemäärittelyksi, jonka perusteella Nestix Oy toteuttaa uudet modulit toiminnanohjausjärjestelmäänsä. Tutkimuksissa havaittiin, että yrityksillä on hyvin samankaltaisia tarpeita varastojen ja hankintojen hallintaan. Varastoinnin ja hankinnan prosessit poikkeavat hyvin vähän yritysten välillä. Samoja perinteisiä logistiikan perustyökaluja käytetään miltei kaikissa yrityksissä. Tulevaisuuden houkuttelevimpana kehitysalueena voidaan pitää ohjelmistojen internet-pohjaisuutta, joka mahdollistaa ohjelmiston käyttämisen mistäpäin maailmaa tahansa ilman erillisiä ohjelmistoasennuksia. Tutkimuksen jälkeen Nestix-ohjelmistoperheeseen toteutettiin integroidut hankinnan sekä varastoinnin modulit. Ohjelmaa on kehitetty tutkimuksen tekemisen jälkeen eteenpäin ja sitä on myyty useaan Euroopan maahan osana Nestix toiminnanohjausjärjestelmää.

Effektivisering av mjukvaruinstallationer : Genom automatiserad mjukvarudistribution

Software deployment, eller mjukvarudistribution översatt till svenska kan ses som processen där alla aktiviteter ingår för att göra en mjukvara tillgänglig för användare utan en manuell installation på användarens dator eller annan maskin. Det finns ett flertal software deployment-verktyg, som hanterar automatiska installationer, tillgängliga för företag på marknaden idag.  Avdelningen HVDC på ABB i Ludvika har behov att börja använda ett verktyg för automatiserade installationer av mjukvaror då installationer idag utförs manuellt och är tidsödande. Som Microsoftpartners vill ABB se hur Microsofts verktyg för mjukvarudistribution skulle kunna hjälpa för detta behov.  Vår studie syftade till att undersöka hur arbetet med installationer av mjukvara ser ut idag, samt hitta förbättringsmöjligheter för installationer som inte kan automatiseras i nuläget. I studien ingick även att ta fram ett generellt ramverk för hur verksamheter kan gå tillväga när de vill börja använda sig utav software deployment-verktyg. I ramverket ingår en utformad kravspecifikation som ska utvärderas mot Microsofts verktyg.  För att skapa en uppfattning om hur arbetet i verksamheten ser ut idag har vi utfört enkätundersökning och intervjuer med personal på HVDC. För att utveckla ett ramverk har vi använt oss av insamlade data från de intervjuer, enkätundersökning och gruppintervju som utförts, detta för att identifiera krav och önskemål från personalen hos ett software deployment-verktyg. Litteraturstudier utfördes för att skapa en teoretisk referensram att utgå ifrån vid utvecklande av ramverket och kravspecifikationen.  Studien har resulterat i en beskrivning av software deployment, förbättringsmöjligheter i arbetet med installationer av mjukvara samt ett generellt ramverk som beskriver hur verksamheter kan gå tillväga när de ska börja använda ett software deployment-verktyg. Ramverket innehåller också en kravspecifikation som använts för att utvärdera Microsofts verktyg för mjukvarudistribution. I vår studie har vi inte sett att någon tidigare har tagit fram ett generellt ramverk och kravspecifikation som verksamheter kan använda sig av som underlag när de ska börja använda ett software deployment-verktyg. Vårt resultat av studien kan täcka upp detta kunskapsgap.    

Estudi de software lliure en diferents entorns

El software lliure està tenint últimament un pes cada cop més important en les empreses, però encara és el gran desconegut per a molta gent. Des de la seva creació als anys 80 fins ara, hi ha hagut un creixement exponencial de software lliure de gran qualitat, oferint eines per a tot tipus de necessitats, eines ofimàtiques, gestors de correu, sistemes de fitxer, sistemes operatius…. Tot aquest moviment no ha passat desapercebut per a molts usuaris i empreses, que s’han aprofitat d’ell per cobrir les seves necessitats. Pel que fa a les empreses, cada cop n’hi ha més que en petita o gran mesura, utilitzen el software lliure, ja sigui per el seu menor cost d’adquisició, o bé per la seva gran fiabilitat o per que és fàcilment adaptable o per no establir cap lligam tecnològic, en definitiva per tenir més llibertat. En el moment de la creació d’una nova empresa, on es parteix de zero en tota la tecnologia informàtica, és el moment menys costòs d’implementar l’arquitectura informàtica amb software lliure, és quan l’impacte que té sobre l’empresa, usuaris i clients és menor. En les empreses que ja tenen un sistema informàtic, caldrà establir un pla de migració, ja sigui total o parcial. La finalitat d’aquest projecte no és la de dir quin software és millor que l’altre o de dir quin s’ha d’instal•lar, sinó el de donar a conèixer el món del software lliure, mostrar part d’aquest software, fer alguna comparativa de software lliure amb software propietari, donant idees i un conjunt de solucions per a empreses, per què una empresa pugui agafar idees d’implementació d’algunes de les solucions informàtiques exposades o seguir algun dels consells proposats. Actualment ja hi ha moltes empreses que utilitzen software lliure. Algunes només n’utilitzen una petita part en les seves instal•lacions, ja que el fet de que una empresa funcioni al 100% amb software lliure, tot i que n’hi comença ha haver, de moment ho considero una mica arriscat, però que en poc temps, aquest fet serà cada cop més habitual.

Improving globally distributed software development and support processes - A workflow view

We propose a new approach and related indicators for globally distributed software support and development based on a 3-year process improvement project in a globally distributed engineering company. The company develops, delivers and supports a complex software system with tailored hardware components and unique end-customer installations. By applying the domain knowledge from operations management on lead time reduction and its multiple benefits to process performance, the workflows of globally distributed software development and multitier support processes were measured and monitored throughout the company. The results show that the global end-to-end process visibility and centrally managed reporting at all levels of the organization catalyzed a change process toward significantly better performance. Due to the new performance indicators based on lead times and their variation with fixed control procedures, the case company was able to report faster bug-fixing cycle times, improved response times and generally better customer satisfaction in its global operations. In all, lead times to implement new features and to respond to customer issues and requests were reduced by 50%.

Vertical Bone Measurements From Cone Beam Computed Tomography Images Using Different Software Packages.

This article aimed at comparing the accuracy of linear measurement tools of different commercial software packages. Eight fully edentulous dry mandibles were selected for this study. Incisor, canine, premolar, first molar and second molar regions were selected. Cone beam computed tomography (CBCT) images were obtained with i-CAT Next Generation. Linear bone measurements were performed by one observer on the cross-sectional images using three different software packages: XoranCat®, OnDemand3D® and KDIS3D®, all able to assess DICOM images. In addition, 25% of the sample was reevaluated for the purpose of reproducibility. The mandibles were sectioned to obtain the gold standard for each region. Intraclass coefficients (ICC) were calculated to examine the agreement between the two periods of evaluation; the one-way analysis of variance performed with the post-hoc Dunnett test was used to compare each of the software-derived measurements with the gold standard. The ICC values were excellent for all software packages. The least difference between the software-derived measurements and the gold standard was obtained with the OnDemand3D and KDIS3D (-0.11 and -0.14 mm, respectively), and the greatest, with the XoranCAT (+0.25 mm). However, there was no statistical significant difference between the measurements obtained with the different software packages and the gold standard (p> 0.05). In conclusion, linear bone measurements were not influenced by the software package used to reconstruct the image from CBCT DICOM data.

Systematic Management of Variability in UML-based Software Product Lines

This paper presents SMarty, a variability management approach for UML-based software product lines (PL). SMarty is supported by a UML profile, the SMartyProfile, and a process for managing variabilities, the SMartyProcess. SMartyProfile aims at representing variabilities, variation points, and variants in UML models by applying a set of stereotypes. SMartyProcess consists of a set of activities that is systematically executed to trace, identify, and control variabilities in a PL based on SMarty. It also identifies variability implementation mechanisms and analyzes specific product configurations. In addition, a more comprehensive application of SMarty is presented using SEI's Arcade Game Maker PL. An evaluation of SMarty and related work are discussed.

Atratividade de projetos de software livre: importância teórica e estratégias para administração

Thousands of Free and Open Source Software Projects (FSP) were, and continually are, created on the Internet. This scenario increases the number of opportunities to collaborate to the same extent that it promotes competition for users and contributors, who can guide projects to superior levels, unachievable by founders alone. Thus, given that the main goal of FSP founders is to improve their projects by means of collaboration, the importance to understand and manage the capacity of attracting users and contributors to the project is established. To support researchers and founders in this challenge, the concept of attractiveness is introduced in this paper, which develops a theoretical-managerial toolkit about the causes, indicators and consequences of attractiveness, enabling its strategic management.

Evaluation of three brands of drug interaction software for use in intensive care units

Objective To evaluate drug interaction software programs and determine their accuracy in identifying drug-drug interactions that may occur in intensive care units. Setting The study was developed in Brazil. Method Drug interaction software programs were identified through a bibliographic search in PUBMED and in LILACS (database related to the health sciences published in Latin American and Caribbean countries). The programs` sensitivity, specificity, and positive and negative predictive values were determined to assess their accuracy in detecting drug-drug interactions. The accuracy of the software programs identified was determined using 100 clinically important interactions and 100 clinically unimportant ones. Stockley`s Drug Interactions 8th edition was employed as the gold standard in the identification of drug-drug interaction. Main outcome Sensitivity, specificity, positive and negative predictive values. Results The programs studied were: Drug Interaction Checker (DIC), Drug-Reax (DR), and Lexi-Interact (LI). DR displayed the highest sensitivity (0.88) and DIC showed the lowest (0.69). A close similarity was observed among the programs regarding specificity (0.88-0.92) and positive predictive values (0.88-0.89). The DIC had the lowest negative predictive value (0.75) and DR the highest (0.91). Conclusion The DR and LI programs displayed appropriate sensitivity and specificity for identifying drug-drug interactions of interest in intensive care units. Drug interaction software programs help pharmacists and health care teams in the prevention and recognition of drug-drug interactions and optimize safety and quality of care delivered in intensive care units.

Developing and implementing an open and non-proprietary device description for FOUNDATION fieldbus based on software standards

Support for interoperability and interchangeability of software components which are part of a fieldbus automation system relies on the definition of open architectures, most of them involving proprietary technologies. Concurrently, standard, open and non-proprietary technologies, such as XML, SOAP, Web Services and the like, have greatly evolved and been diffused in the computing area. This article presents a FOUNDATION fieldbus (TM) device description technology named Open-EDD, based on XML and other related technologies (XLST, DOM using Xerces implementation, OO, XMIL Schema), proposing an open and nonproprietary alternative to the EDD (Electronic Device Description). This initial proposal includes defining Open-EDDML as the programming language of the technology in the FOUNDATION fieldbus (TM) protocol, implementing a compiler and a parser, and finally, integrating and testing the new technology using field devices and a commercial fieldbus configurator. This study attests that this new technology is feasible and can be applied to other configurators or HMI applications used in fieldbus automation systems. (c) 2008 Elsevier B.V. All rights reserved.

A Referential Model for Small Companies of Development Software

Despite the importance of that represent the small software companies in Latin America, the fact of not having its own standards, and able to meet their specific, has created serious difficulties in improving their process and also in quality certification. In this sense and as a contribution to better understanding of the subject they propose a reference model and as a means to validate the proposal, presents a report of its application in a small Brazilian company, committed to certification of the quality model MPS.BR.

The BCD transient recorder revisited: firmware for the ISA-to-USB bridging card and software for the graphical user interface

This report describes recent updates to the custom-built data-acquisition hardware operated by the Center for Hypersonics. In 2006, an ISA-to-USB bridging card was developed as part of Luke Hillyard's final-year thesis. This card allows the hardware to be connected to any recent personal computers via a (USB or RS232) serial port and it provides a number of simple text-based commands for control of the hardware. A graphical user interface program was also updated to help the experimenter manage the data acquisition functions. Sampled data is stored in text files that have been compressed with the gzip for mat. To simplify the later archiving or transport of the data, all files specific to a shot are stored in a single directory. This includes a text file for the run description, the signal configuration file and the individual sampled-data files, one for each signal that was recorded.
