Diagramme de flux de donnéesLe Data Flow Diagram (DFD ; en français, diagramme de flux de données) est un type de représentation graphique du flux de données à travers un système d’information. Cet outil est souvent utilisé comme étape préliminaire dans la conception d’un système afin de créer un aperçu de ce système d’information. De plus, il est également utilisé pour visualiser le traitement de données (structured design). Il montre quel type d’informations entre (input) ou sort (output) du système, d’où elles proviennent et où elles sont stockées.
Diagramme de fluxFlow diagram is a collective term for a diagram representing a flow or set of dynamic relationships in a system. The term flow diagram is also used as a synonym for flowchart, and sometimes as a counterpart of the flowchart. Flow diagrams are used to structure and order a complex system, or to reveal the underlying structure of the elements and their interaction. The term flow diagram is used in theory and practice in different meanings. Most commonly the flow chart and flow diagram are used in an interchangeable way in the meaning of a representation of a process.
Function modelIn systems engineering, software engineering, and computer science, a function model or functional model is a structured representation of the functions (activities, actions, processes, operations) within the modeled system or subject area. A function model, similar with the activity model or process model, is a graphical representation of an enterprise's function within a defined scope. The purposes of the function model are to describe the functions and processes, assist with discovery of information needs, help identify opportunities, and establish a basis for determining product and service costs.
Control-flow diagramA control-flow diagram (CFD) is a diagram to describe the control flow of a business process, process or review. Control-flow diagrams were developed in the 1950s, and are widely used in multiple engineering disciplines. They are one of the classic business process modeling methodologies, along with flow charts, drakon-charts, data flow diagrams, functional flow block diagram, Gantt charts, PERT diagrams, and IDEF. A control-flow diagram can consist of a subdivision to show sequential steps, with if-then-else conditions, repetition, and/or case conditions.
Business process mappingBusiness process mapping refers to activities involved in defining what a business entity does, who is responsible, to what standard a business process should be completed, and how the success of a business process can be determined. The main purpose behind business process mapping is to assist organizations in becoming more effective. A clear and detailed business process map or diagram allows outside firms to come in and look at whether or not improvements can be made to the current process.
Organigramme de programmationthumb|Exemple simple d'organigramme. Un organigramme de programmation (parfois appelé algorigramme, logigramme ou plus rarement ordinogramme) est une représentation graphique normalisée de l'enchaînement des opérations et des décisions effectuées par un programme d'ordinateur. Il existe différents types d'organigrammes, désignés par des néologismes variés : Logigramme Un logigramme est un outil utilisé en Qualité qui permet de visualiser de façon séquentielle et logique les actions à mener et les décisions à prendre pour atteindre un objectif défini.
Business process modelingBusiness process modeling (BPM) in business process management and systems engineering is the activity of representing processes of an enterprise, so that the current business processes may be analyzed, improved, and automated. BPM is typically performed by business analysts, who provide expertise in the modeling discipline; by subject matter experts, who have specialized knowledge of the processes being modeled; or more commonly by a team comprising both. Alternatively, the process model can be derived directly from events' logs using process mining tools.
N2 chartThe N2 chart or N2 diagram (pronounced "en-two" or "en-squared") is a chart or diagram in the shape of a matrix, representing functional or physical interfaces between system elements. It is used to systematically identify, define, tabulate, design, and analyze functional and physical interfaces. It applies to system interfaces and hardware and/or software interfaces. The N-squared chart was invented by the systems engineer Robert J. Lano, while working at TRW in the 1970s and first published in a 1977 TRW internal report.
Flow process chartThe flow process chart is a graphical and symbolic representation of the activities performed on the work piece during the operation in industrial engineering. The first structured method for documenting process flow, e.g., in flow shop scheduling, the flow process chart, was introduced by Frank and Lillian Gilbreth to members of ASME in 1921 as the presentation "Process Charts, First Steps in Finding the One Best Way to Do Work". The Gilbreths' tools quickly found their way into industrial engineering curricula.
Ingénierie des systèmesL'ingénierie des systèmes ou ingénierie système est une approche scientifique interdisciplinaire, dont le but est de formaliser et d'appréhender la conception et la validation de systèmes complexes. L'ingénierie des systèmes a pour objectif de maîtriser et de contrôler la conception de systèmes dont la complexité ne permet pas le pilotage simple. Par système, on entend un ensemble d'éléments humains ou matériels en interdépendance les uns les autres et qui inter-opèrent à l'intérieur de frontières ouvertes ou non sur l'environnement.
