Guidance on software aspects of dependability
IEC 62628:2012 addresses the issues concerning software aspects of dependability and gives guidance on achievement of dependability in software performance influenced by management disciplines, design processes and application environments. It establishes a generic framework on software dependability requirements, provides a software dependability process for system life cycle applications, presents assurance criteria and methodology for software dependability design and implementation and provides practical approaches for performance evaluation and measurement of dependability characteristics in software systems. Keywords: software, performance, dependability

Lignes directrices concernant la sûreté de fonctionnement du logiciel
La CEI 62628:2012 porte sur les problèmes concernant la sûreté de fonctionnement du logiciel et définit les lignes directrices pour la réalisation de la sûreté de fonctionnement dans les performances logicielles influencées par les disciplines de management, les processus de conception et les environnements d'application. Elle définit un cadre générique pour les exigences en matière de sûreté de fonctionnement du logiciel, fournit un processus de sûreté de fonctionnement du logiciel pour les applications du cycle de vie du système, présente les critères d'assurance et la méthodologie pour la conception et la mise en eouvre de la sûreté de fonctionnement du logiciel, et fournit des approches et mesures pratiques des caractéristiques de sûreté de fonctionnement dans les systèmes logiciels. Mots clé: logiciel, fonctionnement, performances
Navodilo o programskih vidikih zagotovljivosti
Ta mednarodni standard obravnava vprašanja v zvezi s programskimi vidiki zagotovljivosti in podaja navodila za doseganje zagotovljivosti pri delovanju programske opreme, na katero vpliva upravljanje disciplin, načrtovanje procesov in okolja aplikacij. Uveljavlja splošni okvir za zahteve programske zagotovljivosti, podaja postopek programske zagotovljivosti za življenjski cikel aplikacij, zagotavlja merila in metodologijo za načrtovanje in implementacijo programske zagotovljivosti ter podaja praktične pristope za oceno delovanja in merjenje značilnosti zagotovljivosti v programskih sistemih. Ta standard se uporablja za navodila razvijalcem in oskrbovalcem programskih sistemov, sistemskim integratorjem, upravljalcem, vzdrževalcem in uporabnikom programskih sistemov, ki jih zanimajo praktični pristopi in aplikacijski inženiring za doseganje zagotovljivosti programskih izdelkov in sistemov.
