Data Flow Diagram Model

Data Flow Diagram Model

Data Flow Diagram (DFD) is a technique of graphical structural analysis, describing the sources external to the system, recipients of data, also logical functions, data flows and data stores that are accessed. The DFD's goal is to show how each process converts its inputs into the outputs and to identify relationships between these processes, at this make the system's description clear and understandable at every level of detail. Historically happened that for describing Data Flow Diagrams are used two notations - Yourdon and Gane-Sarson that differ each from other by graphical representation of symbols. The DFD model, like most other structural models is a hierarchical model. Each process can be subjected to decomposition on the structural components, the relationships between which in the same notation can be shown on a separate diagram. Typically, several DFD models are built when modeling the system. ConceptDraw PRO software enhanced with Data Flow Diagrams solution ideally suits for creation DFD models and professional drawing Data Flow Diagrams. Read more
This picture bar graph sample shows wheat area harvested and production in Peru from 2006 to 2015. It was designed using data from website of the Foreign Agriculfural Service, the U.S. Department of Agriculture (USDA).
"Wheat remains a minor crop in Peru with most of the production concentrated in the temperate, southern highlands. Grown at 2,800 to 3,500 meters above sea level, production remains limited by geography as well as current economics. The Peruvian farmer cultivates only about two hectares of wheat, on average. While wheat production has increased slightly since 1994, it has remained relatively stable for the last six years at around 225,000 MT."

- Machine (technology)
- Method (process)
- Material (Includes Raw Material, Consumables and Information.)
- Man Power (physical work)/Mind Power (brain work): Kaizens, Suggestions
- Measurement (Inspection)
- Milieu/Mother Nature (Environment)
The original 6Ms used by the Toyota Production System have been expanded by some to include the following and are referred to as the 8Ms. However, this is not globally recognized. It has been suggested to return to the roots of the tools and to keep the teaching simple while recognizing the original intent; most programs do not address the 8Ms.

"A biofuel is a fuel that is produced through contemporary biological processes, such as agriculture and anaerobic digestion, rather than a fuel produced by geological processes such as those involved in the formation of fossil fuels, such as coal and petroleum, from prehistoric biological matter. Biofuels can be derived directly from plants, or indirectly from agricultural, commercial, domestic, and/or industrial wastes. Renewable biofuels generally involve contemporary carbon fixation, such as those that occur in plants or microalgae through the process of photosynthesis. Other renewable biofuels are made through the use or conversion of biomass (referring to recently living organisms, most often referring to plants or plant-derived materials). This biomass can be converted to convenient energy-containing substances in three different ways: thermal conversion, chemical conversion, and biochemical conversion. This biomass conversion can result in fuel in solid, liquid, or gas form. This new biomass can also be used directly for biofuels." [Biofuel. Wikipedia]

"A data flow diagram (DFD) is a graphical representation of the "flow" of data through an information system. It differs from the flowchart as it shows the data flow instead of the control flow of the program. A data flow diagram can also be used for the visualization of data processing (structured design). Data flow diagrams were invented by Larry Constantine, the original developer of structured design, based on Martin and Estrin's "data flow graph" model of computation.
It is common practice to draw a context-level Data flow diagram first which shows the interaction between the system and outside entities. The DFD is designed to show how a system is divided into smaller portions and to highlight the flow of data between those parts. This context-level Data flow diagram is then "exploded" to show more detail of the system being modeled" [Data model. Wikipedia]

Process Flowchart

The main reason of using Process Flowchart or PFD is to show relations between major parts of the system. Process Flowcharts are used in process engineering and chemical industry where there is a requirement of depicting relationships between major components only and not include minor parts. Process Flowcharts for single unit or multiple units differ in their structure and implementation. ConceptDraw PRO is Professional business process mapping software for making Process flowcharts, Process flow diagram, Workflow diagram, flowcharts and technical illustrations for business documents and also comprehensive visio for mac application. Easier define and document basic work and data flows, financial, production and quality management processes to increase efficiency of your business with ConcepDraw PRO. Business process mapping software with Flowchart Maker ConceptDraw PRO includes extensive drawing tools, rich examples and templates, process flowchart symbols and shape libraries, smart connectors that allow you create the flowcharts of complex processes, process flow diagrams, procedures and information exchange. Process Flowchart Solution is project management workflow tools which is part ConceptDraw Project marketing project management software. Drawing charts, diagrams, and network layouts has long been the monopoly of Microsoft Visio, making Mac users to struggle when needing such visio alternative like visio for mac, it requires only to view features, make a minor edit to, or print a diagram or chart. Thankfully to MS Visio alternative like ConceptDraw PRO software, this is cross-platform charting and business process management tool, now visio alternative for making sort of visio diagram is not a problem anymore however many people still name it business process visio tools.

Total Quality Management Value

The Total quality management (TQM) is an enterprise-wide method of continuous quality improvement of all organizational processes, including the enhancement of ability to deliver high-quality products and services to the customers. The TQM includes eight main elements, which have great value: customer-focused, process-centered, total employee involvement, integrated system, continual improvement, strategic and systematic approach, fact-based decision making, communications. ConceptDraw PRO diagramming and vector drawing software offers the Total Quality Management Diagram solution with effective drawing tools, predesigned vector elements, samples and templates that help easy design the Total Quality Management diagrams, TQM flowcharts and Mind Maps widely used in quality management projects to visualize the business processes and industrial processes for your organization, to demonstrate the quality control step-by-step in a visual manner, to compare visually the ideal and real stages of processes.

"Productivity is the ratio of output to inputs in production; it is an average measure of the efficiency of production. Efficiency of production means production’s capability to create incomes which is measured by the formula real output value minus real input value.
Productivity is a crucial factor in production performance of firms and nations. Increasing national productivity can raise living standards because more real income improves people's ability to purchase goods and services, enjoy leisure, improve housing and education and contribute to social and environmental programs. Productivity growth also helps businesses to be more profitable." [Productivity. Wikipedia]

Organizational Structure

The organizational structure reflects the composition and hierarchy of company's divisions, determines the distribution of authorities and responsibilities within the organization, and facilitates the understanding by workers their responsibilities. It also defines the group of people making key decisions at the company. Visualization of organizational structure of any company, organization or institution is not an easy task, because sometimes the company may include several departments, each with more than thousand persons. For such large organizations often are created the Organizational charts for every department separately. There are many ways of organization's structuring, which determine its work. Often happens that organizational structure adapts to production process. ConceptDraw PRO extended with unique Organizational Charts solution from Management area of ConceptDraw Solution Park is a powerful organizational structure software, which ideally suits for developing Organizational Charts of any type and any complexity.
