IDEF3 Standard

In contrast to IDEF0 standard, IDEF3 standard is more particularly specialized. This standard is intended for description and further analysis of technological processes of an enterprise. Using IDEF3 standard it is possible to examine and model scenarios of technological processes. Scenario is a description of consecution of properties changes of an object which takes part in the technological process, e.g. half-finished product which is under processing. Each scenario is documented correspondingly. For documenting of the scenario there are two types of documents: documents, which describe properties and consecution of the process execution (standards, methods and technologies description) and documents, which describe results of the process execution (reports and work statistics). IDEF3 standard allows to get information about process and attendant documentation and to analyze it for increasing of the process management effectiveness. Using IDEF3 standard you can collect and document information about processes key points, define the degree of influence on the course of processes execution and model scenarios without change of the production process itself.

There are two types of diagrams in IDEF3 standard. These diagrams describe the same technological process from different sides. First type of diagram is Process Flow Description Diagrams (PFDD). The second type - Object State Transition Network (OSTN) diagrams.

For instance if it is necessary to describe the process of stamping the detail from a billet, the PFDD diagram will contain a description of consecution of actions which are executed with the billet during the given process, and the OSTN diagram will contain the detail states on each process stage.

Rectangular blocks on the diagram are called functional units or Units of Behavior (UOB). Each UOB has the name in the verb form and a unique number and denotes an event within the limits of the process (a stage, an action or decision making). UOB are connected by arrows in consecution of the process execution. There are 3 different kinds of arrows: Precedence arrow - a solid line, which is drawn from left to right or top-down; Relational Link - a dotted line, used for description of relations between UOB; Object Flow - an arrow with two arrow-heads. Such arrow denotes that the object is used in two or more subruns. For example, when the object is created in one subrun and is used in another one.

The block marked with the cross on the diagram is called a Junction. Such blocks are used for indication of decision makings during the process. Accordingly to IDEF3 standard there are two types of Junctions: for confluence (Fan-in Junction) and branching (Fan-out Junction) of arrows. Simultaneous junction and branching is not allowed. Junctions can be of different types. The junction type is denoted on the diagram.

Indication Name Fan-in Junction Fan-out Junction
Asynchronous AND Asynchronous AND All preceding subruns must be completed All subsequent subruns must be started
Synchronous AND Synchronous AND All preceding subruns must be completed simultaneously All subsequent subruns must be started simultaneously
Asynchronous OR Asynchronous OR One or several preceding subruns must be completed One or several subsequent subruns must be started
Synchronous OR Synchronous OR One or several preceding subruns must be completed simultaneously One or several subsequent subruns must be started simultaneously
Synchronous OR XOR (Exclusive OR) Only one preceding process must be completed Only one subsequent process must be started

All junctions in PFDD are numerated, each number has prefix "J", e.g. J1, J2 and so on.

Each UOB can be represented in the form of sequence of blocks with the necessary degree of detailed elaboration. For example the block “Testing of a detail” can be represented in the form of sequence of blocks, which in their turn will form PFDD diagram. Such diagram will be called a Child diagram, and the initial diagram – a Parent diagram.

The OSTN diagram represents a list of object state and descriptions of influences which correspond to UOB blocks from the corresponding PFDD diagram. Object states are represented by circumferences and their changes – by directed lines, which are signed the same way as corresponding UOB blocks.

Job duties in small companies are usually spread randomly among workers, causing lots of problems and misunderstanding. One of the ways to restore order in business processing is to create a cross-functional flowchart with swim lanes that would represent every step in production system. Another advantage of using swim lanes flowchart is that it represents not only processes, but people responsible for them. Swim lane diagram is a kind of a process flow diagram. Its special feature is that it joins the features of process flow diagrams with organizational charts. Thus, a swim lane diagram display a participant of the business process in a conjunction with general flow of the business system. A swim lane diagram is looks similar to a swimming pool's lanes. Lanes can be horizontal and vertical. The lanes are pointed out relatively to resource name, which is assigned on implementation of the given part of the business process. ConceptDraw Business Process Mapping solution delivers the ability to design develop swim lanes flowcharts using the vector graphic objects of Swim Lanes library.Swim Lane Diagrams *

If we divide computer networks by scale, we get several main categories. The smallest network is PAN, as it connects personal devices themselves, and as the number of users grows, a local area network can be recognized, and campus area networks (CAN) connects several local networks located within some area like a university or a corporation. Computers connected to CAN share public educational materials and list of CAN network examples includes such prestigious universities like Stanford and Carnegie Mellon. This is an example of a computer network diagram created for a campus area network. It was created using using ConceptDraw solution for the Computer and Network diagramming. The specific of this sample campus network is its distribution. It is rather broad to embrace a big campus territory. This diagram can be applied as a template for designing custom area network topology diagram for a particular educational institution.Campus Area Networks (CAN). <br>Computer and Network Examples *

Bureaucratic companies usually are characterized by a strict hierarchy and clearly defined responsibilities. However, sometimes organizational structure of a company reminds of somewhat tangled. To clarify it, you can create an orgchart that will represent the company as a tree with its' departments as branches. This organization diagram represents a tree-like organizational structure. This is a typical example of a top-level branches of the hierarchical organizational structure. This part of the tree shows heads of branches who are subordinated completely to the president. The information and solutions are distributed though a tree structure down to the company's departments. Each of the sub-division has its own structure that is reflected in the corresponding organizational chart. This orgchart diagram was created using the vector graphic library supplied with ConceptDraw Organizational Charts solution.Organizational Structure *

A flowchart is a powerful tool for examining processes. It helps improving processes a lot, as it becomes much easier to communicate between involved people, to identify potential problems and to optimize workflow. There are flowcharts of different shapes, sizes and types of flowchart vary from quite basic process flowcharts to complex program flowcharts. Nevertheless, all these diagrams use the same set of special symbols like arrows to connect blocks, parallelogram to show data receiving or rectangles for showing process steps. Basic flowcharts are used to represent a simple process algorithm. A basic flowchart notation consists of rectangles (business processes), arrows (the flow of information, documents, etc.). The same notation is used in items such as the "decision", which allow you to do the branching. To indicate the start of the entire business process and its termination can be used the "Terminator" element. The advantages of Basic Flowchart are simplicity and clarity. With it you can quickly describe the business process steps. Creating of Basic Flowchart does not require any special knowledge, as easily understand by employees with different levels of education and IQ.Types of Flowchart — Overview
