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.

Swim Lane Diagrams

Swim Lane Diagrams are the kind of process flow diagrams and effective tool for documenting the business processes required for any business company for its productive work, for easy defining the weak points, reasons of defects, or delays during the process. Swim Lane Diagram is based on the IDEF3 standard and was developed primarily for using in projecting. Its name derives from the use of horizontal or vertical lanes. The blocks that denote the parts of the processes are arranged within definite lanes according to the belonging to responsible worker. So the process of any complexity is visually divided into the parts and represented with indication the responsibility for execution of each part. This significantly facilitates the comprehension of its work. Use the ConceptDraw DIAGRAM software and predesigned vector objects from the Swim Lanes library of Business Process Mapping Solution included to ConceptDraw Solution Park to easy develop Swim Lanes Flowcharts and Diagrams, for modeling and documenting the business processes in a simple and visual graphic form.

Structured Systems Analysis and Design Method (SSADM) with ConceptDraw DIAGRAM

Structured Systems Analysis and Design Method (abbr. SSADM) is a method developed in Great Britain and accepted in 1993 as a national standard for information systems development and analysis. SSADM is based on Data Flow Diagrams and is characterized with presence of clear sequence of steps at projecting, analysis, and documenting of information system. It involves 6 main stages: analysis of existing system or estimation of practicability, requirements definition, determination of technical requirements and equipment cost, development of logical data model, projecting of logical requirements and specification them, physical projecting. Each of them is also divided into several steps defining the tasks that should be fulfilled at a given stage. The most important SSADM elements are flows modeling with help of DFD, data logic modeling with help of LDS (Logical Data Structure) and description of entities behavior. Applying of SSADM is easy with ConceptDraw DIAGRAM diagramming and vector drawing software and Data Flow Diagram solution.
