20.500.12556/DKUM-92538 A product quality impacts of a mobile software product line an empirical study Background: The software product lines (SPL) enable development teams to fully address a systematic reuse of shared assets to deliver a family of similar software products. Mobile applications are an obvious candidate for employing an SPL approach. This paper presents our research outcomes, based on empirical data from an industry-level development project. Two development teams were confronted with the same functionalities set to be delivered through a family of native mobile applications for Android and iOS. Methods: Empirical data was gathered before, during and after a year of full-time development. The data demonstrate the impact of a SPL approach by comparing the SPL and non-SPL multiple edition development. One family of products (Android apps) was developed using an SPL approach, while another (iOS apps), functionally the same, was developed without employing an SPL approach. The project generated a volume of raw and aggregated empirical data to support our research questions. Results: The paper reports a positive impact of an SPL approach on product quality (internal and external) and feature output per week. As data shows, it also increases the delivery of functionalities (240% in 6 more editions), while investing the same amount of effort needed for a single-edition development. As a result of system-supported separation of development and production code, developers had a high confidence in further development. On the other hand, the second team delivered less new functionalities, only two new application editions, and lower software quality than the team that manages multi-edition development by employing an SPL approach. software product line Android simultaneous development iOS Software quality software product editions programska oprema proizvodnja programske opreme kakovost programske opreme mobilne aplikacije true false true PeerJ Angleški jezik Slovenski jezik Znanstveno delo 2025-04-17 12:00:44 2025-04-17 12:49:23 2025-04-18 03:08:49 0000-00-00 00:00:00 2021 0 0 Str. 1-26 št. članka 434 Letn. 7 27 April 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2020-10-23 2021-02-17 2021-04-27 004.5 61614595 10.7717/peerj-cs.434 2376-5992 Pavlic-2021-A_product_quality_impacts_of_a_mob.pdf Pavlic-2021-A_product_quality_impacts_of_a_mob.pdf 1 81BF6DB6CF1D66E5976330D9B3560B81 0d64dec2bd6bcd5dbb9dcd69ca3c35f5e740191f040c8dfca2b83c5299c5c736 80a99b7b-1b79-11f0-a1d4-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=190376 https://doi.org/10.7717/peerj-cs.434 0 d54afd74-1b72-11f0-a1d4-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=190373 Fakulteta za elektrotehniko, računalništvo in informatiko 0 0 0
