How to Create an IDEF0 Diagram for an Application Development

IDEF0 methods are intended to model the functions of a process, creating a graphical model that displays: what controls the function, who makes it, what resources are used and how they are connected with other functions. The IDEF0 tool is used to model the decisions, actions, and activities of a software system during the development process. IDEF0 diagram graphically depicts a model of a desired version of the application. ConceptDraw DIAGRAM allows you to create and communicate the IDEF0 diagrams of any complexity.

IDEF0 standard with ConceptDraw DIAGRAM

The activity of any organization is more or less branchy network of processes. The description of these processes is a hard technical task which requires definite methodology and standards.
According to the IDEF0 standard any process can be described in the form of a block (Activity Box) which has inputs and outputs. The process consists in transformation of inputs into outputs under the influence of the management and in the presence of necessary resources. Outputs of the given process later on can be either inputs for the next process or resources, or management means.

"Verification and Validation of Computer Simulation Models is conducted during the development of a simulation model with the ultimate goal of producing an accurate and credible model.
"Simulation models are increasingly being used to solve problems and to aid in decision-making. The developers and users of these models, the decision makers using information obtained from the results of these models, and the individuals affected by decisions based on such models are all rightly concerned with whether a model and its results are “correct”". This concern is addressed through verification and validation of the simulation model.
Simulation models are approximate imitations of real-world systems and they never exactly imitate the real-world system. Due to that, a model should be verified and validated to the degree needed for the models intended purpose or application.
The verification and validation of simulation model starts after functional specifications have been documented and initial model development has been completed. Verification and validation is an iterative process that takes place throughout the development of a model." [Verification and Validation of Computer Simulation Models. Wikipedia]

How to Create an IDEF0 Diagram

IDEF0 is a modeling tool used to model the decisions, actions, and activities of an organization or system. IDEF0 is capable of graphically representing a wide variety of business, manufacturing and other types of enterprise operations to any level of detail. An IDEF0 diagram describes an idealized model of a system or process. ConceptDraw has created a solution that collects all symbols necessary to create professional IDEF0 diagrams, as well as templates and step-by-step lessons that help create your own process diagram from the ground up. The IDEF Business Process Diagrams solution for ConceptDraw DIAGRAM contains extensive libraries of vector stencils that allow users to create professional looking diagrams of any complexity. The power of ConceptDraw DIAGRAM means that recording a business process is a quick and painless task - smart connectors allow you to map your diagram on the screen almost as quickly as it comes to mind.
"IDEF0 may be used to model a wide variety of automated and non-automated systems. For new systems, it may be used first to define the requirements and specify the functions, and then to design an implementation that meets the requirements and performs the functions. For existing systems, IDEF0 can be used to analyze the functions the system performs and to record the mechanisms (means) by which these are done. The result of applying IDEF0 to a system is a model that consists of a hierarchical series of diagrams, text, and glossary cross-referenced to each other. The two primary modeling components are functions (represented on a diagram by boxes) and the data and objects that inter-relate those functions (represented by arrows)." [IDEF0. Wikipedia]

This IDEF0 diagram sample was created on the base of the figure from the California Water Plan website. [waterplan.water.ca.gov/ technical/ cwpu2009/ flowdiaghtml/ dgm18.htm]
"The California Water Plan provides a collaborative planning framework for elected officials, agencies, tribes, water and resource managers, businesses, academia, stakeholders, and the public to develop findings and recommendations and make informed decisions for California's water future. The plan, updated every five years, presents the status and trends of California's water-dependent natural resources; water supplies; and agricultural, urban, and environmental water demands for a range of plausible future scenarios. The California Water Plan also evaluates different combinations of regional and statewide resource management strategies to reduce water demand, increase water supply, reduce flood risk, improve water quality, and enhance environmental and resource stewardship. The evaluations and assessments performed for the plan help identify effective actions and policies for meeting California's resource management objectives in the near term and for several decades to come."

The vector stencils library "IDEF0 diagrams" contains 18 symbols for drawing IDEF0 function modeling diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"The IDEF0 model ... is based on a simple syntax. Each activity is described by a verb-based label placed in a box. Inputs are shown as arrows entering the left side of the activity box while output are shown as exiting arrows on the right side of the box. Controls are displayed as arrows entering the top of the box and mechanisms are displayed as arrows entering from the bottom of the box. Inputs, Controls, Outputs, and Mechanisms are all referred to as concepts.
- Arrow : A directed line, composed of one or more arrow segments, that models an open channel or conduit conveying data or objects from source (no arrowhead) to use (with arrowhead). There are 4 arrow classes: Input Arrow, Output Arrow, Control Arrow, and Mechanism Arrow (includes Call Arrow). See Arrow Segment, Boundary Arrow, Internal Arrow.
- Box : A rectangle, containing a name and number, used to represent a function.
- Context : The immediate environment in which a function (or set of functions on a diagram) operates.
- Decomposition : The partitioning of a modeled function into its component functions.
- Fork : The junction at which an IDEF0 arrow segment (going from source to use) divides into two or more arrow segments. May denote unbundling of meaning.
- Function : An activity, process, or transformation (modeled by an IDEF0 box) identified by a verb or verb phrase that describes what must be accomplished.
- Join : The junction at which an IDEF0 arrow segment (going from source to use) merges with one or more other arrow segments to form a single arrow segment. May denote bundling of arrow segment meanings.
- Node : A box from which child boxes originate; a parent box. See Node Index, Node Tree, Node Number, Node Reference, Diagram Node Number." [IDEF0. Wikipedia]

"Functional decomposition refers broadly to the process of resolving a functional relationship into its constituent parts in such a way that the original function can be reconstructed (i.e., recomposed) from those parts by function composition. In general, this process of decomposition is undertaken either for the purpose of gaining insight into the identity of the constituent components (which may reflect individual physical processes of interest, for example), or for the purpose of obtaining a compressed representation of the global function, a task which is feasible only when the constituent processes possess a certain level of modularity (i.e., independence or non-interaction). Interactions between the components are critical to the function of the collection. All interactions may not be observable, but possibly deduced through repetitive perception, synthesis, validation and verification of composite behavior." [Functional decomposition. Wikipedia]
