Ketterät menetelmät ja laadunhallinta

Ketterien menetelmien käyttö on yleistymässä ohjelmistotuotannossa. Tämän vuoksi ketteriltä menetelmiltä vaaditaan hyvää laadunhallintaa. Ketteriä menetelmiä on olemassa useita erilaisia, mutta ne kaikki jakavat samanlaiset perusarvot ja periaatteet. Tässä työssä tutkitaan kolmea eri ketterää menetelmää: Scrum, eXtreme Programming (XP) sekä Dynamic Systems Development Method (DSDM). Jokaisesta menetelmästä selvitetään, miten niissä hoidetaan laadunhallinta. Työssä otetaan myös kantaa ketterien ja perinteisten menetelmien eroihin sekä siihen, millaisissa projekteissa ketteriä menetelmiä kannattaa käyttää.

Erikoispuristimen kehitys liikkuvalle raaka-ainerainalle

Tutkimuksen tavoitteena oli kehittää Lappeenrannan teknilliselle yliopistolle nopeasti ja ketterästi liikkuva, lävistyksiä ja muovauksia tekevä puristin. Laitteisto on tarkoitus liittää osaksi tuotantolinjaa, jossa suulakepuristin eli ekstruuderi tuottaa pehmeä, ei-metallista materiaalia katkeamattomasti. Teoriaosuudessa esitellään vaihtoehdot puristimen, ohjauksen, työkalun ja liikutuslaitteiston osalta. Empiriaosuudessa suoritetaan laitteiston eri komponenttien valinta hinnan, nopeuden, kestävyyden, käytettävyyden ja koon perusteella. Tutkimuksen lopussa arvioidaan laitteistokokonaisuuden nopeutta suulakepuristimen tuotaman materiaalin maksiminopeuteen. Laitteiston nopeuden rajoittavana tekijänä toimii puristimen iskunopeus, jonka perusteella suulakepuristimen tuottaman materiaalin etenemisnopeus joudutaan pudottamaan hieman alle puoleen tavoitteena olleesta nopeudesta. Laitteiston kestävyyden heikon kohta on työstöä tekevien komponenttien liikuttamiseen tarkoitettu laitteisto. Puristuslaitteistoa on tarkoitus käyttää kahdeksan tuntia päivässä, viitenä päivänä viikossa, 52 viikkoa vuodessa. Näiden käyttötietojen perusteella koko laitteiston käyttöikä on useita vuosia.

The impact of the law 10,267/2001 in the brazilian rural registration

The publication of the Law 10,267 of 08/28/2001 changed the paradigm of rural registration in Brazil, because this law known as the "Law of Georeferencing" has created the National Registration of Rural Property, that unifies in a common basis different registrations present in several government agencies, such as the National Institute for Colonization and Agrarian Reform (INCRA), the Secretariat of Federal Revenue, the Brazilian Institute of Environment and Natural Resources, and the National Indian Foundation. Also, this new registration system has a graphical component which has not existed until such date, where the boundaries of rural property are georeferenced to the Brazilian Geodetic System. This new paradigm has resulted in a standardization of the survey and its representation of rural properties according to the Technical Standard for Georeferencing of Rural Properties, published by INCRA in compliance with the new legislation. Due to the georeferencing, the creation of a public GIS of free access on the Internet was possible. Among the difficulties found it may be observed the great Brazilian territory, the need for specialized professionals, and especially the certification process that INCRA has to perform for each georeferenced property. It is hoped that this last difficulty is solved with the implementation of the Land Management System that will allow automated and online certification, making the process more transparent, agile and fast.

Software Development Process Modeling. Developers Perspective to Contemporary Modeling Techniques

Formal software development processes and well-defined development methodologies are nowadays seen as the definite way to produce high-quality software within time-limits and budgets. The variety of such high-level methodologies is huge ranging from rigorous process frameworks like CMMI and RUP to more lightweight agile methodologies. The need for managing this variety and the fact that practically every software development organization has its own unique set of development processes and methods have created a profession of software process engineers. Different kinds of informal and formal software process modeling languages are essential tools for process engineers. These are used to define processes in a way which allows easy management of processes, for example process dissemination, process tailoring and process enactment. The process modeling languages are usually used as a tool for process engineering where the main focus is on the processes themselves. This dissertation has a different emphasis. The dissertation analyses modern software development process modeling from the software developers’ point of view. The goal of the dissertation is to investigate whether the software process modeling and the software process models aid software developers in their day-to-day work and what are the main mechanisms for this. The focus of the work is on the Software Process Engineering Metamodel (SPEM) framework which is currently one of the most influential process modeling notations in software engineering. The research theme is elaborated through six scientific articles which represent the dissertation research done with process modeling during an approximately five year period. The research follows the classical engineering research discipline where the current situation is analyzed, a potentially better solution is developed and finally its implications are analyzed. The research applies a variety of different research techniques ranging from literature surveys to qualitative studies done amongst software practitioners. The key finding of the dissertation is that software process modeling notations and techniques are usually developed in process engineering terms. As a consequence the connection between the process models and actual development work is loose. In addition, the modeling standards like SPEM are partially incomplete when it comes to pragmatic process modeling needs, like light-weight modeling and combining pre-defined process components. This leads to a situation, where the full potential of process modeling techniques for aiding the daily development activities can not be achieved. Despite these difficulties the dissertation shows that it is possible to use modeling standards like SPEM to aid software developers in their work. The dissertation presents a light-weight modeling technique, which software development teams can use to quickly analyze their work practices in a more objective manner. The dissertation also shows how process modeling can be used to more easily compare different software development situations and to analyze their differences in a systematic way. Models also help to share this knowledge with others. A qualitative study done amongst Finnish software practitioners verifies the conclusions of other studies in the dissertation. Although processes and development methodologies are seen as an essential part of software development, the process modeling techniques are rarely used during the daily development work. However, the potential of these techniques intrigues the practitioners. As a conclusion the dissertation shows that process modeling techniques, most commonly used as tools for process engineers, can also be used as tools for organizing the daily software development work. This work presents theoretical solutions for bringing the process modeling closer to the ground-level software development activities. These theories are proven feasible by presenting several case studies where the modeling techniques are used e.g. to find differences in the work methods of the members of a software team and to share the process knowledge to a wider audience.

Application of the scrum framework in non-software project management

Scrum is an agile project management approach that has been widely practiced in the software development projects. It has proven to increase quality, productivity, customer satisfaction, transparency and team morale among other benefits from its implementation. The concept of scrum is based on the concepts of incremental innovation strategies, lean manufacturing, kaizen, iterative development and so on and is usually contrasted with the linear development models such as the waterfall method in the software industry. The traditional approaches to project management such as the waterfall method imply intensive upfront planning and approval of the entire project. These sort of approaches work well in the well-defined stable environments where all the specifications of the project are known in the beginning. However, in the uncertain environments when a project requires continuous development and incorporation of new requirements, they do not tend to work well. The scrum framework was inspiraed by Nonaka’s article about new product developement and was later adopted by software development practitioners. This research explores conditions for and benefits of the application of scrum framework beyond software development projects. There are currently a few case studies on the scrum implementation in non-software projects, but there is a noticeable trend of it in the scrum practitioners’ community. The research is based on the real-life context multiple case study analysis of three different non-software projects. The results of the research showed that in order to succeed within scrum projects need to satisfy certain conditions – necessary and sufficient. Among them the key factors are uncertainty of the project environment, not well defined outcomes, commitment of the scrum teams and management support. The top advantages of scrum implementation identified in the present research include improved transparency, accountability, team morale, communications, cooperation and collaboration. Further researches are advised to be carried out in order to validate these findings on a larger sample and to focus on more specific areas of scrum project management implementation.

Ulkomaalaisen yrityksen verkostosuhteet Venäjällä

Tutkimuksen tavoitteena on konkreettisen yritysverkoston avulla selvittää, minkälaisia ovat ulkomaalaisen yrityksen potentiaaliset kumppanit ja yritysten väliset suhteet Venäjällä. Toisena tavoitteena on kuvata käytännön työelämään sopivalla menetelmällä riittävän kokonaisvaltaisesti yritysverkoston kumppanit sekä kumppaneiden ja kärkiyrityksen väliset suhteet. Samalla tarkastellaan yritysten välisten suhteiden riskejä. Selvitysmenetelmällä pyritään nopeuteen ja ketteryyteen ja sen tavoitteena on lisätä ulkomaisen johdon käsitystä yritysverkostosta johdon päätöksentekoa varten. Tutkimus jakaantuu teoria tarkasteluun ja yhden Venäjällä toimivan ulkomaisen yrityksen osto-osaston verkostoa selvittävään empiiriseen osaan. Teoriatarkastelussa selvitetään erilaisia lähestymistapoja ja laajempia viitekehyksiä yritysverkostojen tutkimukseen. Teoriatarkastelun perusteella valittiin viitekehykset yrityskumppaneiden ja yritysten välisen suhteen sekä riskien arviointiin. Empiirisen osan tutkimus toteutettiin haastattelukyselytutkimuksena perustuen näihin viitekehyksiin. Yrityskumppaneita ja yritysten välisiä suhteita tarkastellaan tilastollisin menetelmin ja riskejä arvioidaan laadullisella tutkimusotteella. Tutkimustulokset vastaavat monelta osin liiketoimintakulttuurista ja –ympäristöstä saatua kokemukseen ja tutkimustietoon perustuvaa käsitystä. Verkostoitumisen kulmakivet ovat hyvin toimivat ja määritellyt vaihdannan liiketoiminta- ja tukiprosessit, hyvin tunnetut kumppanit ja tälle perustalle rakennetut sosiaaliset suhteet sekä liiketoimintaympäristöön ja –kulttuuriin soveltuvat yhteistyökompetenssit. Tutkitun yritysverkoston yhteistyösuhteet voidaan jakaa hierarkkiseen organisaatiokumppanuuteen, toimittajakumppanuuteen, luottamukseen perustuvaan markkinaehtoiseen suhteeseen ja opportunistiseen markkinasuhteeseen. Hyviä yhteistyökumppaneita ja –suhteita löytyy taustaltaan erilaisista toimittajista. Tutkimuksessa käytetyt viitekehykset toimivat hyvin erityisesti yrityskumppanin arvioinnissa. Yritysten välisen suhteen arviointiin käytetyn viitekehyksen ongelmat liittyivät lähinnä erilaiseen liiketoimintakulttuuriin ja käsitykseen yritysten välisestä strategisesta suhteesta. Riskit liittyivät toimitussuhteeseen useammin kuin omaan organisaatioon tai toimittajaan.

The marketing communications industry in flux: Large B2C advertisers’ viewpoint

The recent digitization, fragmentation of the media landscape and consumers’ changing media behavior are all changes that have had drastic effects on creating marketing communications. In order to create effective marketing communications large advertisers are now co-operating with a variety of marketing communications companies. The purpose of the study is to understand how advertisers perceive these different companies and more importantly how do advertisers expect their roles to change in the future as the media landscape continues to evolve. Especially the changing roles of advertising agencies and media agencies are examined as they are at the moment the most relevant partners of the advertisers. However, the research is conducted from a network perspective rather than focusing on single actors of the marketing communications industry network. The research was conducted using a qualitative theme interview method. The empirical data was gathered by interviewing representatives from nine of the 50 largest Finnish advertisers measured by media spending. Thus, the research was conducted solely from large B2C advertisers’ perspective while the views of their other relevant actors of the network were left unexplored. The interviewees were chosen with a focus on variety of points of view. The analytical framework that was used to analyze the gathered data was built the IMP group’s industrial network model that consists of actors, their resources and activities. As technology driven media landscape fragmentation and consumers’ changing media behavior continue to increase the complexity of creating marketing communications, advertisers are going to need to rely on a growing number of partnerships as they see that the current actors of the network will not be able to widen their expertise to answer to these new needs. The advertisers expect to form new partnerships with actors that are more specialized and able to react and produce activities more quickly than at the moment. Thus, new smaller and more agile actors with looser structures are going to appear to fill these new needs. Therefore, the need of co-operation between the actors is going to become more important. These changes pose the biggest threat for traditional advertising agencies as they were seen as being most unable to cope with the ongoing change. Media agencies are in a more favorable position for remaining relevant for the advertisers as they will be able to justify their activities and provided value by leveraging their data handling abilities. In general the advertisers expect to be working with a limited number of close actors and in addition having a network of smaller actors, which are used on a more ad hoc basis.

Ohjelmistotuotannon menetelmien käyttö sulautetuissa järjestelmissä

Sulautettujen järjestelmien tekemisessä käytettävät metodit ovat moninaiset. Tämä johtuu siitä, että sulautettuja järjestelmiä on tuhansia erilaisia, sekä laitteiston ja ohjelmiston rakentamisen eroavaisuuksista. Sovellukset vaihtelevat kännyköistä aina avaruusluotaimiin. Näihin projekteihin on sovellettu metodeita joita ei ole alun perin suunniteltu laitteiston ja ohjelmiston yhteissuunnitteluun ja toteuttamiseen. Ohjelmistotuotannon menetelmistä oikean valinta nimenomaan tietylle sulautetulle järjestelmälle on haasteellista. Viimeisimpinä ovat tulleet erilaiset ketterät menetelmät ja niitäkin on olemassa useita erilaisia. Ketteriä ja perinteisempiä ohjelmistotuotannon menetelmiä esitellään tässä kandidaatin työssä. Tässä työssä on tarkoituksena selvittää mitkä olisivat parhaiten soveltuvia sulautetun järjestelmän projektille.

Tunable lumped-element bandpass filters for Cognitive Radio application

In this thesis the design of bandpass filters tunable at 400 MHz – 800 MHz was under research. Microwave filters are vital components which provide frequency selectivity in wide variety of electronic systems operating at high frequencies. Due to the occurrence of multi-frequency bands communication and diverse applications of wireless devices, requirement of tunable filters exists. The one of potential implementation of frequency-agile filters is frontends and spectrum sensors in Cognitive Radio (CR). The principle of CR is to detect and operate at a particular available spectrum without interfering with the primary user’s signals. This new method allows improving the efficiency of utilizing allocated spectrum such as TV band (400 MHz – 800 MHz). The focus of this work is development of sufficiently compact, low cost tunable filters with quite narrow bandwidth using currently available lumped-element components and PCB board technology. Filter design, different topologies and methods of tuning of bandpass filters are considered in this work. As a result, three types of topologies of bandpass filter were simulated and realised. They use digitally tunable capacitors (DTCs) for adjusting central frequency at TV "white space" spectrum. Measurements revealed that schematics presented in this work have proper output response and filters are successfully tuned by DTCs.

Ketterien menetelmien hyödyntäminen sulautettujen järjestelmien kehityksessä

Sulautettujen järjestelmien projekti voidaan toteuttaa monella tavalla. Projektiin liittyy aina ohjelmiston, sekä laitteiston kehittäminen. Ohjelmiston suunnittelulla on suuri painoarvo ja tämä näkyy erityisesti varsinkin kulutuselektroniikassa. Kannettavien laitteiden räjähdysmäisesti lisääntynyt myynti ja käyttö ovat tuoneet markkinoille lisää rahaa ja mielenkiintoa. Tästä johtuen markkinoille tulee joka vuosi entistä kehittyneempiä laitteita. Laitteiston kehittymisen sekä asiakkaiden vaatimusten lisääntyessä ohjelmistojen koko on kasvanut. Tämä on luonut tarpeen myös sulautettujen järjestelmien projekteille ottaa käyttöön jokin tietty metodi ohjelmistojen tuotannossa. Ongelmana on kuitenkin se, että sulautettujen järjestelmien projekteihin on sovellettu metodeita, joita ei ole alun perin suunniteltu laitteiston ja ohjelmiston yhteissuunnitteluun ja toteuttamiseen. Miten voidaan valita oikea metodi sulautettujen järjestelmien projektiin? Tässä työssä esitellään perinteisiä ohjelmistotuotannon metodeita, sekä keskitytään eri ketterien metodien tutkimiseen. Tämä työ selvittää mikä vaikuttaa metodin valintaan sulautetun järjestelmän projektille. Tässä tutkimuksessa päädytään siihen johtopäätökseen, että sulautetuin järjestelmän suunnittelussa ja toteutuksessa ketterien menetelmien käyttö parantaa projektin mahdollisuutta onnistua täyttämään asiakkaan vaatimukset. Ketterien menetelmien käyttö ei poista tarvetta kehittää menetelmää, joka lähtökohtaisesti ottaa huomioon laitteiston ja ohjelmiston yhteissuunnittelun.

Scaling up stepwise feature introduction to construction of large software systems

Developing software is a difficult and error-prone activity. Furthermore, the complexity of modern computer applications is significant. Hence,an organised approach to software construction is crucial. Stepwise Feature Introduction – created by R.-J. Back – is a development paradigm, in which software is constructed by adding functionality in small increments. The resulting code has an organised, layered structure and can be easily reused. Moreover, the interaction with the users of the software and the correctness concerns are essential elements of the development process, contributing to high quality and functionality of the final product. The paradigm of Stepwise Feature Introduction has been successfully applied in an academic environment, to a number of small-scale developments. The thesis examines the paradigm and its suitability to construction of large and complex software systems by focusing on the development of two software systems of significant complexity. Throughout the thesis we propose a number of improvements and modifications that should be applied to the paradigm when developing or reengineering large and complex software systems. The discussion in the thesis covers various aspects of software development that relate to Stepwise Feature Introduction. More specifically, we evaluate the paradigm based on the common practices of object-oriented programming and design and agile development methodologies. We also outline the strategy to testing systems built with the paradigm of Stepwise Feature Introduction.

Agility in international fast fashion retailing

The birth of Internet technologies, the developments of fast fashion and multiple retailing channels have created a need for a new, more integrated way for doing retailing. Agility in fast fashion retailing could be seen as a significant way of responding to these changes and furthermore, as a way to respond to consumers’ altering demands. The purpose of this study was to explore the ways in which agile supply chains and integrated multichannel retailing influence the international fast fashion retailing. A framework for agility in retail was developed based on available theoretical considerations in distribution and communication channels. Qualitative research methods and qualitative content analysis were used. Four expert interviews were carried out to gain new perspectives to the objectives. The rest of the data was collected from an industry specific document, expert video and two expert lectures. Following the data collection, the research material was analyzed with qualitative content analysis. The empirical findings on agility in retail were presented based on a coding frame. It was found that agility in retail has multiple parts, which are overlapping and affecting one another. Furthermore, instead of viewing the agile supply chain and integrated multichannel retailing separately of each other as usual, it was found that they should be integrated, and the term “agility” was proposed to denote this approach. Also, it was found that the most common drivers and constrains of integrated multichannel retailing were the new Internet technologies and customer demand. Brick-and-mortar store, online store, mobile devices and social media were found to be the most common retailing channels. Furthermore, in-store technology, click-and-collect approach, NFC-buying, RFID-technology as well as 3D- digital simulations on fabrics and patterns will enhance agility even more in the future. In addition, environmental issues, customer experiences and communication will be important factors. This study has provided new practical insights for the future retailing. Furthermore, it has contributed to the academic research by discussing the traditional approaches of agility in fast fashion retail and bringing in new insights.

Tietojohtaminen ketterässä ohjelmistokehityksessä (scrum): Case Samlink

Yleisesti voidaan sanoa, että suuri osa ohjelmistokehitys -projekteista epäonnistuu. Tämä johtuu kehitykseen kohdistuvista aikarajoitteista, muuttuvista vaatimuksista sekä nopeasti muuttuvasta teknologiasta. Scrum -menetelmä on yksi vaihtoehto kehitettäessä ohjelmistoja alati muuttuvassa ympäristössä. Scrum -menetelmän säännöt on helppo oppia, mutta menetelmän tehokas hallinta vaatii kuitenkin harjoittelua. Tietojohtamisen keinoin voidaan kuitenkin pyrkiä tehostamaan tätä scrum -menetelmän täysimääräistä hyödyntämistä. Tutkimus toteutettiin laadullisin menetelmin tapaustutkimuksena.
