Systems modelingSystems modeling or system modeling is the interdisciplinary study of the use of models to conceptualize and construct systems in business and IT development. A common type of systems modeling is function modeling, with specific techniques such as the Functional Flow Block Diagram and IDEF0. These models can be extended using functional decomposition, and can be linked to requirements models for further systems partition.
Gestion cybernétiqueLa gestion cybernétique est le domaine de la cybernétique qui s'intéresse à la gestion et à l'organisation. Stafford Beer fut le premier à introduire l'idée vers la fin des années 1950. Un degré important de complexité est inhérent aux systèmes dynamiques à cause de leur nature non-linéaire ; ainsi il est difficile de les observer et maîtriser. Cependant, la seule façon de surmonter cette complexité est d'abord de reconnaître son existence.
DurabilitéLes termes durabilité ou soutenabilité sont utilisés depuis les années 1990 pour désigner une configuration de la société humaine qui lui permet d'assurer sa pérennité. Une telle organisation humaine repose sur le maintien d'un environnement vivable, permettant le développement économique et social à l'échelle planétaire et, selon les points de vue, sur une organisation sociale équitable. La période de transition vers la durabilité peut se faire par le développement durable, via la transition énergétique et la transition écologique notamment.
Non-functional requirementIn systems engineering and requirements engineering, a non-functional requirement (NFR) is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviours. They are contrasted with functional requirements that define specific behavior or functions. The plan for implementing functional requirements is detailed in the system design. The plan for implementing non-functional requirements is detailed in the system architecture, because they are usually architecturally significant requirements.
Sustainable productsSustainable products are those products that provide environmental, social and economic benefits while protecting public health and environment over their whole life cycle, from the extraction of raw materials until the final disposal. According to Belz, Frank-Martin., the definition of sustainable product has six characteristics: Customer satisfaction: any products or services that do not meet customer needs will not survive in the market in a long term.
Second-order cyberneticsSecond-order cybernetics, also known as the cybernetics of cybernetics, is the recursive application of cybernetics to itself and the reflexive practice of cybernetics according to such a critique. It is cybernetics where "the role of the observer is appreciated and acknowledged rather than disguised, as had become traditional in western science". Second-order cybernetics was developed between the late 1960s and mid 1970s by Heinz von Foerster and others, with key inspiration coming from Margaret Mead.
Sustainable dietSustainable diets are "dietary patterns that promote all dimensions of individuals’ health and wellbeing; have low environmental pressure and impact; are accessible, affordable, safe and equitable; and are culturally acceptable". These diets are nutritious, eco-friendly, economically sustainable, and accessible to people of various socioeconomic backgrounds. Sustainable diets attempt to address nutrient deficiencies (e.g., undernourishment) and excesses (e.g.
Software requirements specificationA software requirements specification (SRS) is a description of a software system to be developed. It is modeled after the business requirements specification (CONOPS). The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.
Sustainable livingSustainable living describes a lifestyle that attempts to reduce the use of Earth's natural resources by an individual or society. Its practitioners often attempt to reduce their ecological footprint (including their carbon footprint) by altering their home designs and methods of transportation, energy consumption and diet. Its proponents aim to conduct their lives in ways that are consistent with sustainability, naturally balanced, and respectful of humanity's symbiotic relationship with the Earth's natural ecology.
Stratégie d'entrepriseLa stratégie d'entreprise est l'ensemble des choix d'allocation de ressources qui définissent le périmètre d'activité d'une organisation en vue de réaliser ses objectifs. Les axes de stratégies classiques cherchent à assurer sa rentabilité, son développement, sa pérennité et le bien-être qu'elle apporte aux salariés. Elle correspond aux axes de développement choisis pour l'entreprise et se concrétise à travers un système d'objectifs et un modèle économique (ou une chaîne de valeur) piloté par un processus décisionnel complexe : la décision stratégique.
Cadre ZachmanLe cadre Zachman est un cadre d'architecture d'entreprise qui permet d'une manière formelle et hautement structurée de définir le système d'information d'une entreprise. Il utilise un modèle de classification à deux dimensions basé sur : six interrogations de base : Quoi, Comment, Où, Qui, Quand, et Pourquoi (What, How, Where, Who, When, Why), qui croisent six types de modèles distincts qui se rapportent à des groupes de parties prenantes : Visionnaire, Propriétaire, Concepteur, Réalisateur, Sous-traitant et Exécutant (visionary, owner, designer, builder, implementer, worker) pour présenter une vue holistique de l'entreprise qui est modélisée.
Service-oriented modelingService-oriented modeling is the discipline of modeling business and software systems, for the purpose of designing and specifying service-oriented business systems within a variety of architectural styles and paradigms, such as application architecture, service-oriented architecture, microservices, and cloud computing. Any service-oriented modeling method typically includes a modeling language that can be employed by both the "problem domain organization" (the business), and "solution domain organization" (the information technology department), whose unique perspectives typically influence the service development life-cycle strategy and the projects implemented using that strategy.
