A simple flowchart representing a process for dealing with a non-functioning lamp.. A flowchart is a type of diagram that represents a workflow or process.A flowchart can also be defined as a diagrammatic representation of an algorithm, a step-by-step approach to solving a task.
It is used when observing a physical process, to record actions as they happen, and thus get an accurate description of the process. It is used when analyzing the steps in a process, to help identify and eliminate waste—thus, it is a tool for efficiency planning. It is used when the process is mostly sequential, containing few decisions.
This thesis details the development and validation of logic flow diagrams for the activities composing the pre-project planning process. Generic in nature, these diagrams utilize the activities found within the Project Definition Rating Index (PDRI) for Building Projects, a scope definition measurement tool developed by the Construction ...
If swim lanes are used then a private business process will be contained within a single Pool. The Sequence Flow of the Process is therefore contained within the Pool and cannot cross the boundaries of the Pool. Message Flow can cross the Pool boundary to show the interactions that exist between separate private business processes.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Parallel lines divide the chart into lanes, with one lane for each person, group or sub process. Lanes are labelled to show how the chart is organized. In the accompanying example, the vertical direction represents the sequence of events in the overall process, while the horizontal divisions depict what sub-process is performing that step.
The process is named in one word, a short sentence, or a phrase that is clearly to express its essence. [7] Data flow. Data flow (flow, dataflow) shows the transfer of information (sometimes also material) from one part of the system to another. The symbol of the flow is the arrow.
Figure 1: Functional flow block diagram format. [1] A functional flow block diagram (FFBD) is a multi-tier, time-sequenced, step-by-step flow diagram of a system's functional flow. [2] The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ...
