Come le startup selezionano i software di project management?

Il presente lavoro di tesi punta a cercare di capire quali funzionalità, le startup del settore IT ritengono più utili all’interno dei software di project management. L’approccio per rispondere alla domanda sarà quello di intervistare startup presenti in diversi incubatori italiani ed elaborare i dati raccolti. Le aziende dovranno essere operanti nel settore informatico ed avere massimo 7 anni. Nel primo periodo di ricerca ho analizzato le funzionalità descritte nella letteratura scientifica e ho trovato che quanto presente non fosse compatibile con le attuali necessità e caratteristiche delle startup. Per avvalorare quanto affermo, sottoporrò un questionario alle startup compatibili con i requisiti, in cui valuterò se concordano o smentiscono ciò che dichiaro. L’intervista sarà rivolta ai project manager delle aziende, verrà loro sottoposto un questionario online in cui dovranno esprimere una preferenza tra 2 elenchi di funzionalità e indicare qual è maggiormente compatibile con le loro esigenze. In base alla scelta che effettueranno gli verrà domandato quali funzionalità tra quelle elencate ritengono più utili per i loro bisogni aziendali. Al termine della ricerca verranno elaborate le informazioni osservando se hanno trovato più utile il nuovo elenco di funzionalità e quali funzionalità sono considerate maggiormente necessarie a soddisfare le esigenze aziendali.

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.

Agile Methods in Small Software Projects

Agile software development methods are attempting to provide an answer to the software development industry's need of lighter weight, more agile processes that offer the possibility to react to changes during the software development process. The objective of this thesis is to analyze and experiment the possibility of using agile methods or practices also in small software projects, even in projects containing only one developer. In the practical part of the thesis a small software project was executed with some agile methods and practices that in the theoretical part of the thesis were found possible to be applied to the project. In the project a Bluetooth proxy application that is run in the S60 smartphone platform and PC was developed further to contain some new features. As a result it was found that certain agile practices can be useful even in the very small projects. The selection of the suitable practices depends on the project and the size of the project team.

THE IMPACT OF ARCHITECTURAL DESIGN ON SOFTWARE DEVELOPMENT

Tässä työssä tutkitaan ohjelmistoarkkitehtuurisuunnitteluominaisuuksien vaikutusta erään client-server –arkkitehtuuriin perustuvan mobiilipalvelusovelluksen suunnittelu- ja toteutusaikaan. Kyseinen tutkimus perustuu reaalielämän projektiin, jonka kvalitatiivinen analyysi paljasti arkkitehtuurikompponenttien välisten kytkentöjen merkittävästi vaikuttavan projektin työmäärään. Työn päätavoite oli kvantitatiivisesti tutkia yllä mainitun havainnon oikeellisuus. Tavoitteen saavuttamiseksi suunniteltiin ohjelmistoarkkitehtuurisuunnittelun mittaristo kuvaamaan kyseisen järjestelmän alijärjestelmien arkkitehtuuria ja luotiin kaksi suunniteltua mittaristoa käyttävää, työmäärää (komponentin suunnittelu-, toteutus- ja testausaikojen summa) arvioivaa mallia, joista toinen on lineaarinen ja toinen epälineaarinen. Näiden mallien kertoimet sovitettiin optimoimalla niiden arvot epälineaarista gloobaalioptimointimenetelmää, differentiaalievoluutioalgoritmia, käyttäen, niin että mallien antamat arvot vastasivat parhaiten mitattua työmäärää sekä kaikilla ominaisuuksilla eli attribuuteilla että vain osalla niistä (yksi jätettiin vuorotellen pois). Kun arkkitehtuurikompenttien väliset kytkennät jätettiin malleista pois, mitattujen ja arvoitujen työmäärien välinen ero (ilmaistuna virheenä) kasvoi eräässä tapauksessa 367 % entisestä tarkoittaen sitä, että näin muodostettu malli vastasi toteutusaikoja huonosti annetulla ainestolla. Tämä oli suurin havaitu virhe kaikkien poisjätettyjen ominaisuuksien kesken. Saadun tuloksen perusteella päätettiin, että kyseisen järjestelmän toteutusajat ovat vahvasti riippuvaisia kytkentöjen määrästä, ja näin ollen kytkentöjen määrä oli mitä todennäköisemmin kaikista tärkein työmäärään vaikuttava tekijä tutkitun järjestelmän arkkitehtuurisuunnittelussa.

Towards increased productivity and quality in software development using agile, lean and collaborative approaches

Dagens programvaruindustri står inför alltmer komplicerade utmaningar i en värld där programvara är nästan allstädes närvarande i våra dagliga liv. Konsumenten vill ha produkter som är pålitliga, innovativa och rika i funktionalitet, men samtidigt också förmånliga. Utmaningen för oss inom IT-industrin är att skapa mer komplexa, innovativa lösningar till en lägre kostnad. Detta är en av orsakerna till att processförbättring som forskningsområde inte har minskat i betydelse. IT-proffs ställer sig frågan: “Hur håller vi våra löften till våra kunder, samtidigt som vi minimerar vår risk och ökar vår kvalitet och produktivitet?” Inom processförbättringsområdet finns det olika tillvägagångssätt. Traditionella processförbättringsmetoder för programvara som CMMI och SPICE fokuserar på kvalitets- och riskaspekten hos förbättringsprocessen. Mer lättviktiga metoder som t.ex. lättrörliga metoder (agile methods) och Lean-metoder fokuserar på att hålla löften och förbättra produktiviteten genom att minimera slöseri inom utvecklingsprocessen. Forskningen som presenteras i denna avhandling utfördes med ett specifikt mål framför ögonen: att förbättra kostnadseffektiviteten i arbetsmetoderna utan att kompromissa med kvaliteten. Den utmaningen attackerades från tre olika vinklar. För det första förbättras arbetsmetoderna genom att man introducerar lättrörliga metoder. För det andra bibehålls kvaliteten genom att man använder mätmetoder på produktnivå. För det tredje förbättras kunskapsspridningen inom stora företag genom metoder som sätter samarbete i centrum. Rörelsen bakom lättrörliga arbetsmetoder växte fram under 90-talet som en reaktion på de orealistiska krav som den tidigare förhärskande vattenfallsmetoden ställde på IT-branschen. Programutveckling är en kreativ process och skiljer sig från annan industri i det att den största delen av det dagliga arbetet går ut på att skapa något nytt som inte har funnits tidigare. Varje programutvecklare måste vara expert på sitt område och använder en stor del av sin arbetsdag till att skapa lösningar på problem som hon aldrig tidigare har löst. Trots att detta har varit ett välkänt faktum redan i många decennier, styrs ändå många programvaruprojekt som om de vore produktionslinjer i fabriker. Ett av målen för rörelsen bakom lättrörliga metoder är att lyfta fram just denna diskrepans mellan programutvecklingens innersta natur och sättet på vilket programvaruprojekt styrs. Lättrörliga arbetsmetoder har visat sig fungera väl i de sammanhang de skapades för, dvs. små, samlokaliserade team som jobbar i nära samarbete med en engagerad kund. I andra sammanhang, och speciellt i stora, geografiskt utspridda företag, är det mera utmanande att införa lättrörliga metoder. Vi har nalkats utmaningen genom att införa lättrörliga metoder med hjälp av pilotprojekt. Detta har två klara fördelar. För det första kan man inkrementellt samla kunskap om metoderna och deras samverkan med sammanhanget i fråga. På så sätt kan man lättare utveckla och anpassa metoderna till de specifika krav som sammanhanget ställer. För det andra kan man lättare överbrygga motstånd mot förändring genom att introducera kulturella förändringar varsamt och genom att målgruppen får direkt förstahandskontakt med de nya metoderna. Relevanta mätmetoder för produkter kan hjälpa programvaruutvecklingsteam att förbättra sina arbetsmetoder. När det gäller team som jobbar med lättrörliga och Lean-metoder kan en bra uppsättning mätmetoder vara avgörande för beslutsfattandet när man prioriterar listan över uppgifter som ska göras. Vårt fokus har legat på att stöda lättrörliga och Lean-team med interna produktmätmetoder för beslutsstöd gällande så kallad omfaktorering, dvs. kontinuerlig kvalitetsförbättring av programmets kod och design. Det kan vara svårt att ta ett beslut att omfaktorera, speciellt för lättrörliga och Lean-team, eftersom de förväntas kunna rättfärdiga sina prioriteter i termer av affärsvärde. Vi föreslår ett sätt att mäta designkvaliteten hos system som har utvecklats med hjälp av det så kallade modelldrivna paradigmet. Vi konstruerar även ett sätt att integrera denna mätmetod i lättrörliga och Lean-arbetsmetoder. En viktig del av alla processförbättringsinitiativ är att sprida kunskap om den nya programvaruprocessen. Detta gäller oavsett hurdan process man försöker introducera – vare sig processen är plandriven eller lättrörlig. Vi föreslår att metoder som baserar sig på samarbete när processen skapas och vidareutvecklas är ett bra sätt att stöda kunskapsspridning på. Vi ger en översikt över författarverktyg för processer på marknaden med det förslaget i åtanke.

A systematic literature review on agile project

In the 21st century, agile project management (APM) has emerged as a major evolutionary step in the area of software project management. APM is defined as a conceptual framework, consisting of various methods such as Scrum, quick respond to change, better customer collaboration, minimum coverage of documentation and extreme programming (XP) that facilitates to produce working software in multiple iterations with team work. Because agile project management has become more popular in the software industry in recent years, it constitutes an interesting and comprehensive research topic. This thesis presents a systematic literature review (SLR) of published research articles concerning agile project management. Based on a predefined search strategy, 273 such articles were identified, of which 44 were included in the review. The selected 44 articles were published between years 2005 and 2012. The thesis defines a review process by developing a review protocol and presenting the results of the review. The results are expected to provide researchers, software man

Knowledge-based risk management: Survey on Brazilian software development enterprises

A risks management, carried on in an effective way, leads the software development to success and may influence on the organization. The knowledge takes part of such a process as a way to help taking decisions. This research aimed to analyze the use of Knowledge Management techniques to the Risk Management in software projects development and the possible influence on the enterprise revenue. It had, as its main studying subject, Brazilian incubated and graduated software developing enterprises. The chosen research method was the Survey type. Multivariate statistical methods were used for the treatment and analysis of the obtained results, this way identifying the most significant factors, that is, enterprise's achievement constraining factors and those outcome achievement ones. Among the latter we highlight the knowledge methodology, the time of existence of the enterprise, the amount of employees and the knowledge externalization. The results encourage contributing actions to the increasing of financial revenue. © 2013 Springer-Verlag.

Explaining Endogenous Control Change in Outsourced Software Projects

Given the centrality of control for achieving success in outsourced software projects, past research has identified key exogenous factors that determine the choice of controls. This view of exogenously driven control choice is based on a number of assumptions; particularly, clients and vendors are seen as separate cognitive entities that combat opportunistic threats under environmental uncertainty by one-off choices or infrequent revisions of controls. In this paper we complement this perspective by acknowledging that an outsourced software project may be characterized as a collective, evolving process faced with the challenge of coping with cognitive limitations of both client and vendor through a continuous process of learning. We argue that if viewed in this way, controls are less subject of a deliberate choice but rather are subject of endogenously driven change, i.e. controls evolve in close interaction with the evolving software project. Accordingly, we suggest a complementary model of endogenous control, where controls mediate individual and collective learning processes. Our research contributes to a better understanding of the dynamics in outsourced software projects. It also spells out methodological implications that may help improve cross-section control research.

A systematic mapping study on the open source software development process.

Abstract?Background: There is no globally accepted open source software development process to define how open source software is developed in practice. A process description is important for coordinating all the software development activities involving both people and technology. Aim: The research question that this study sets out to answer is: What activities do open source software process models contain? The activity groups on which it focuses are Concept Exploration, Software Requirements, Design, Maintenance and Evaluation. Method: We conduct a systematic mapping study (SMS). A SMS is a form of systematic literature review that aims to identify and classify available research papers concerning a particular issue. Results: We located a total of 29 primary studies, which we categorized by the open source software project that they examine and by activity types (Concept Exploration, Software Requirements, Design, Maintenance and Evaluation). The activities present in most of the open source software development processes were Execute Tests and Conduct Reviews, which belong to the Evaluation activities group. Maintenance is the only group that has primary studies addressing all the activities that it contains. Conclusions: The primary studies located by the SMS are the starting point for analyzing the open source software development process and proposing a process model for this community. The papers in our paper pool that describe a specific open source software project provide more regarding our research question than the papers that talk about open source software development without referring to a specific open source software project.

Are team personality and climate related to satisfaction and software quality? Aggregating results from a twice replicated experiment

Research into software engineering teams focuses on human and social team factors. Social psychology deals with the study of team formation and has found that personality factors and group processes such as team climate are related to team effectiveness. However, there are only a handful of empirical studies dealing with personality and team climate and their relationship to software development team effectiveness. Objective We present aggregate results of a twice replicated quasi-experiment that evaluates the relationships between personality, team climate, product quality and satisfaction in software development teams. Method Our experimental study measures the personalities of team members based on the Big Five personality traits (openness, conscientiousness, extraversion, agreeableness, neuroticism) and team climate factors (participative safety, support for innovation, team vision and task orientation) preferences and perceptions. We aggregate the results of the three studies through a meta-analysis of correlations. The study was conducted with students. Results The aggregation of results from the baseline experiment and two replications corroborates the following findings. There is a positive relationship between all four climate factors and satisfaction in software development teams. Teams whose members score highest for the agreeableness personality factor have the highest satisfaction levels. The results unveil a significant positive correlation between the extraversion personality factor and software product quality. High participative safety and task orientation climate perceptions are significantly related to quality. Conclusions First, more efficient software development teams can be formed heeding personality factors like agreeableness and extraversion. Second, the team climate generated in software development teams should be monitored for team member satisfaction. Finally, aspects like people feeling safe giving their opinions or encouraging team members to work hard at their job can have an impact on software quality. Software project managers can take advantage of these factors to promote developer satisfaction and improve the resulting product.

Análisis de la calidad y productividad en el desarrollo de un proyecto software en una microempresa con TSPi

Este artículo presenta el análisis de los resultados obtenidos al aplicar TSPi en el desarrollo de un proyecto software en una microempresa desde el punto de vista de la calidad y la productividad. La organización en estudio necesitaba mejorar la calidad de sus procesos pero no contaba con los recursos económicos que requieren modelos como CMMI-DEV. Por esta razón, se decidió utilizar un proceso adaptado a la organización basado en TSPi, observándose una reducción en la desviación de las estimaciones, un incremento en la productividad, y una mejora en la calidad.---ABSTRACT---This article shows the benefits of developing a software project using TSPi in a “Very Small Enterprise” based in quality and productivity measures. An adapted process from the current process based on the TSPi was defined and the team was trained in it. The workaround began by gathering historical data from previous projects in order to get a measurement repository, and then the project metrics were collected. Finally, the process, product and quality improvements were verified.

Configuración de un entorno de trabajo para el desarrollo de software ágil con integración continua

Hoy en día, existen numerosos sistemas (financieros, fabricación industrial, infraestructura de servicios básicos, etc.) que son dependientes del software. Según la definición de Ingeniería del Software realizada por I. Sommerville, “la Ingeniería del Software es una disciplina de la ingeniería que comprende todos los aspectos de la producción de software desde las etapas iniciales de la especificación del sistema, hasta el mantenimiento de éste después de que se utiliza.” “La ingeniería del software no sólo comprende los procesos técnicos del desarrollo de software, sino también actividades tales como la gestión de proyectos de software y el desarrollo de herramientas, métodos y teorías de apoyo a la producción de software.” Los modelos de proceso de desarrollo software determinan una serie de pautas para poder desarrollar con éxito un proyecto de desarrollo software. Desde que surgieran estos modelos de proceso, se investigado en nuevas maneras de poder gestionar un proyecto y producir software de calidad. En primer lugar surgieron las metodologías pesadas o tradicionales, pero con el avance del tiempo y la tecnología, surgieron unas nuevas llamadas metodologías ágiles. En el marco de las metodologías ágiles cabe destacar una determinada práctica, la integración continua. Esta práctica surgió de la mano de Martin Fowler, con el objetivo de facilitar el trabajo en grupo y automatizar las tareas de integración. La integración continua se basa en la construcción automática de proyectos con una frecuencia alta, promoviendo la detección de errores en un momento temprano para poder dar prioridad a corregir dichos errores. Sin embargo, una de las claves del éxito en el desarrollo de cualquier proyecto software consiste en utilizar un entorno de trabajo que facilite, sistematice y ayude a aplicar un proceso de desarrollo de una forma eficiente. Este Proyecto Fin de Grado (PFG) tiene por objetivo el análisis de distintas herramientas para configurar un entorno de trabajo que permita desarrollar proyectos aplicando metodologías ágiles e integración continua de una forma fácil y eficiente. Una vez analizadas dichas herramientas, se ha propuesto y configurado un entorno de trabajo para su puesta en marcha y uso. Una característica a destacar de este PFG es que las herramientas analizadas comparten una cualidad común y de alto valor, son herramientas open-source. El entorno de trabajo propuesto en este PFG presenta una arquitectura cliente-servidor, dado que la mayoría de proyectos software se desarrollan en equipo, de tal forma que el servidor proporciona a los distintos clientes/desarrolladores acceso al conjunto de herramientas que constituyen el entorno de trabajo. La parte servidora del entorno propuesto proporciona soporte a la integración continua mediante herramientas de control de versiones, de gestión de historias de usuario, de análisis de métricas de software, y de automatización de la construcción de software. La configuración del cliente únicamente requiere de un entorno de desarrollo integrado (IDE) que soporte el lenguaje de programación Java y conexión con el servidor. ABSTRACT Nowadays, numerous systems (financial, industrial production, basic services infrastructure, etc.) depend on software. According to the Software Engineering definition made by I.Sommerville, “Software engineering is an engineering discipline that is concerned with all aspects of software production from the early stages of system specification through to maintaining the system after it has gone into use.” “Software engineering is not just concerned with the technical processes of software development. It also includes activities such as software project management and the development of tools, methods, and theories to support software production.” Software development process models determine a set of guidelines to successfully develop a software development project. Since these process models emerged, new ways of managing a project and producing software with quality have been investigated. First, the so-called heavy or traditional methodologies appeared, but with the time and the technological improvements, new methodologies emerged: the so-called agile methodologies. Agile methodologies promote, among other practices, continuous integration. This practice was coined by Martin Fowler and aims to make teamwork easier as well as automate integration tasks. Nevertheless, one of the keys to success in software projects is to use a framework that facilitates, systematize, and help to deploy a development process in an efficient way. This Final Degree Project (FDP) aims to analyze different tools to configure a framework that enables to develop projects by applying agile methodologies and continuous integration in an easy and efficient way. Once tools are analyzed, a framework has been proposed and configured. One of the main features of this FDP is that the tools under analysis share a common and high-valued characteristic: they are open-source. The proposed framework presents a client-server architecture, as most of the projects are developed by a team. In this way, the server provides access the clients/developers to the tools that comprise the framework. The server provides continuous integration through a set of tools for control management, user stories management, software quality management, and software construction automatization. The client configuration only requires a Java integrated development environment and network connection to the server.

Looking for the Holy Grail of Software Development

The history of Software Engineering has been marked by many famous project failures documented in papers, articles and books. This pattern of lack of success has prompted the creation of dozens of software analysis, requirements definition, and design methods, programming languages, software development environments and software development processes all promoted as solving ?the software problem.? What we hear less about are software projects that were successful. This article reports on the findings of an extensive analysis of successful software projects that have been reported in the literature. It discusses the different interpretations of success and extracts the characteristics that successful projects have in common. These characteristics provide Software Project Managers with an agenda of topics to be addressed that will help ensure, not guarantee, that their software project will be successful.
