Application of the relevant standards in auditing software requirement engineering

Inženiring zahtev je ključni začetni korak pri razvoju programske opreme. Gre za skupek procesov, katerih namen je pretvorba ugotovljenih potreb deležnikov v primerno oblikovane specifikacije zahtev programske opreme. Te predstavljajo vhod in so izhodišče za nadaljnje korake v razvoju programske opreme. Neprimerno in nepopolno oblikovane zahteve lahko povzročijo številne ovire ter vplivajo na uspešnost projekta razvoja programske opreme. Zato je smiselno, da pri pripravah zahtev programske opreme sledimo obstoječim dobrim praksam, smernicam in standardom. Eden izmed slednjih je tudi standard ISO/IEC/IEEE 29148:2018. Aktualna verzija v domeno inženiringa zahtev programske opreme uvršča tri procese življenjskega cikla, opredeljene v sorodnih standardih. V prispevku so predstavljeni omenjeni standard in z njim močno prepletena standarda. Prikazan je njihov pomen pri izvedbi revizijskega posla preverjanja skladnosti inženiringa zahtev s standardom ISO/IEC/IEEE 29148:2018. V teoretičnem delu prispevka najprej predstavimo pojma programska oprema in programsko inženirstvo ter življenjski cikel programske opreme. Sledi obravnava domene in procesov inženiringa zahtev, pri čemer s praktičnimi primeri preverjanja skladnosti opravil v aktivnostih procesa prikažemo eno izmed možnih poti revidiranja inženiringa zahtev programske opreme.

Software requirement engineering is a key initial step within the software development process. It represents a set of processes resulting in appropriately defined software requirement specifications based on the identified stakeholders needs. Requirements present input and provide the basis for the following steps in the software development process. Improperly and incompletely formulated requirements can pose several challenges and impact the success of a software development project. Therefore, it is crucial to follow existing good practices, guidelines and standards when outlining software requirements. One of the available standards is the ISO/IEC/IEEE 29148:2018. The current version covers three processes addressing the software requirements engineering domain that are defined by related standards. The paper presents the ISO/IEC/IEEE 29148:2018 standard and intertwined standards, emphasising their importance within audit, focusing on verifying the compliance of software requirement engineering. The paper first presents the concepts of software, software engineering and software life cycle, followed by the presentation of the software requirement engineering domain from the perspective of considered standards. The second part of the paper supplement the theoretical knowledge by presenting several practical audit examples addressing the verification of the compliance with the selected standard, presenting one of the possible ways of auditing the software requirement engineering domain.
