Abstract
Tarkvaraarendus on endiselt võrdlemisi uus ja arenev valdkond. Tarkvaraettevõtted on otsinud tarkvara arendusprotsessi parendamist (ingl SPI) aastaid, kuid tegu on mitmekülgse valdkonnaga. Antud magistritöö eesmärk on pakkuda suurt pilti väleda tarkvaraarenduse meetoditest ja tavadest tarkvara arendusprotsessi parendamise kontekstis. Lisaks eelmainitule on antud töö eesmärgiks minna rohkem süvitsi väledate tarkvaraarenduse meetodite alamhulgaga laiahaardelisema kaardistamistöö raames, mis uurib SPI hetkeseisu kirjanduses. Leidmaks vastuseid töös püstitatud uuritavatele küsimustele, viidi antud töö raames läbi süstemaatiline kirjanduse ülevaade. Kirjanduse ülevaate tulemused valideeriti erinevates Eesti tarkvaraettevõtetes viies läbi küsitlusi. Avaldatud teoste, mis hõlmavad tarkvaraarenduse meetodite kasutamist SPI kontekstis aastane avaldamishulk on vaikselt kasvanud aastate jooksul. Kirjandusülevaate tulemused viitavad, et väledate meetodite kasutamine SPI jaoks pole ainult idee. Avaldatud teoste hulgas on võrdlemisi võrdselt teoseid, mis analüüsivad antud teemat idee tasandil ning neid, mis kirjeldavad väledate tarkvaraarenduse meetodite kasutamist ka professionaalses töös. Lisaks sellele viitavad tulemused, et professionaalide jaoks potentsiaalselt kasulikke teoseid on kirjanduses suur kogus. Enimuuritud väleda tarkvaraarenduse meetodid SPI kontekstis on Scrum ning Extreme Programming. Kõige enam mainitakse kirjanduses tavasid nagu pidev integratsioon, kõigepealt testi ning igapäevaste koosolekute pidamine. Kogu uuritud kirjanduses on piisvalt tõendeid tööstusest väledate meetodite kasutamisest SPI tarbeks, mida kinnistavad ka Eestis opereerivates tarkvaraettevõtetes läbiviidud küsitluse tulemused.
Software development in general is still a fairly new and evolving field. Software development companies have been looking for software process improvement (SPI) for years, but the field of SPI is a diverse one. The goal of the Master’s thesis at hand is to provide the big picture of the use of agile methodologies along with its practices in the context of SPI within the current literature. Furthermore, the paper at hand aims to provide more insight into the subset of agile practices of a bigger, more general systematic mapping study on the current state of the art of software process improvement. To find answers to the research questions stated in the thesis, systematic literature review was conducted. The results of the literature review were validated by conducting surveys amongst professionals in several Estonian software development companies with varying sizes. The publication rate of papers concerning agile practices in the context of SPI shows a steady rise over the years. Results of the literature review show that the field of agile practices in SPI is fairly evenly balanced regarding being a concept or being adapted and evaluated in the industry. Furthermore, the results indicate that the there are many papers published that are of high relevance to industry professionals. By far the most discussed agile methods in the literature regarding SPI are Scrum and Extreme Programming while the most addressed practices include integrating often, testing first and conducting daily meetings. Within the analysed papers there are plenty of evidence from the industry of using agile methods in SPI. The survey conducted amongst several Estonian companies confirms that the use of agile practices in SPI is a relevant topic and that Scrum being the most popular topic in the literature is not a coincidence.
