The sequence symbol,the decision symbol,the decision construct if ... thenthe decision construct if ... then ... elsethe repetition construct - repeat,the repetition construct - while, there are other symbols but the real work is depicted by the two symbols and the constructs. The language of flow charts Repeat loop. Is a repeat loop a good idea in this case? While loop. P.O.
A flowchart is a type of diagram that represents an algorithm, workflow or process, showing the steps as boxes of various kinds, and their order by connecting them with arrows. This diagrammatic representation illustrates a solution to a given problem. Flowcharts are used in analyzing, designing, documenting or managing a process or program in various fields. Overview Flowcharts are used in designing and documenting complex processes or programs.
A processing step, usually called activity, and denoted as a rectangular boxa decision, usually denoted as a diamond. A flowchart is described as "cross-functional" when the page is divided into different swimlanes describing the control of different organizational units. Flowcharts depict certain aspects of processes and they are usually complemented by other types of diagram. History Flowchart building blocks Examples Symbols Arrows. Workflow. A workflow consists of an orchestrated and repeatable pattern of business activity enabled by the systematic organization of resources into processes that transform materials, provide services, or process information. It can be depicted as a sequence of operations, declared as work of a person or group, an organization of staff, or one or more simple or complex mechanisms.
Workflows may be viewed as one fundamental building block to be combined with other parts of an organisation's structure such as information silos, teams, projects, policies and hierarchies. Historical development The development of the concept of workflow occurred over a series of loosely defined, overlapping, eras. Beginnings in manufacturing The modern history of workflows can be traced to Frederick Taylor and Henry Gantt. Information-based workflows began to grow during this era, although the concept of an information flow lacked flexibility. Maturation and growth Quality era
