Value stream with ConceptDraw DIAGRAM

The Value stream is a totality of all actions on the projection, order composition and production: starting from creation a product project to launching this product, from order to delivery, from extraction of raw materials to ready product manufacturing. Value stream mapping is a process of visualization of these actions and creation of a detailed and graphical map which will give the possibility to cover the whole consecution of actions at once, to study and analyze it. Value stream map unites all information and material flows therefore such diagram let you see and comprehend the flow of materials, resources and documents in the process of a product manufacturing. As a rule Value stream maps are created manually on a paper, but with the help of ConceptDraw library objects you can create such map more accurately and quickly.

Value stream method was developed and applied for the first time by Toyota company chief engineer in 80th of the last century as the new method of working out of wastes and for creation of more economical and competitive production. At the beginning this approach was head for the increase of productivity, which could help to discover shortages in relation to wastes and the quality of the system in general. Nevertheless this method is applied not only at work with the problem of wastes, but also with the problem of the low quality on the whole.

The goal of the Value stream mapping is to reduce the quantity of wastes in the system of the final product manufacturing. By this method wastes are defined as resources motion, which does not increase the value of the final product but wastes resources. This method can help managers, planners, engineers, suppliers and clients to discover points of wastes rise in the system, to define reasons of wastes rise, to reduce their quantity and thus to increase the effectiveness of work of the whole system.

In the process of Value stream map creation usually two schemes are created- of the current and future states. When the new state is achieved the scheme of the future state becomes the scheme of the current state and the next scheme of the future state is elaborated.

The constituents of stream in Value Stream Map may be materials (at products manufacturing), projects (at projection), clients’ needs (at service providing) and so on.

Wastes in the production system are divided into 7 categories:

Wastes connected with quality

  • Defects correction

Categories connected with human resources

  • Unplanned motions
  • Unplanned processes
  • Waiting

Categories connected with material resources

  • Unplanned materials transferring
  • Overproduction
  • Floats

As soon as streams in Value Stream Map are divided into material and informational, objects of these streams are denoted by different images.

Also the so-called Tact time is shown on the scheme, which is defined as the relation of the effective working time for one shift to needs of the customer for a shift. For example if the tact time is 5 minutes so every 5 minutes the ready product will be manufactured on the production line or one client will be served, and so on.

You can see below an example of Value Stream Map (Current State scheme).

Data Flow Diagram (DFD) →

In software engineering, it is important to understand how the system would cooperate with external sources, like data sources. To give this information a visual representation, data flow diagrams (DFD) were used for years. The entire system is usually divided into smaller ones, and all of them process data flows in appropriate ways. The visualizing business processes which engages the data transfer, is commonly preformed using DFDs (data flow diagrams). DFD is used to show the data flow processing and transformation. This DFD represents the electronic system of a customer purchase. It was created using Gane/Sarson notation. Data flow diagrams helps you to sort through and clarify transferring process making it available for analysis, and representation. ConceptDraw DFD solution introduces the vector library, containing the full set of icons from DFD notations.Data Flow Diagram (DFD) *

Electrical Symbols — Transformers and Windings →

A transformer is an electrical device that transfers electrical energy between two or more circuits through electromagnetic induction. Electromagnetic induction produces an electromotive force within a conductor which is exposed to time varying magnetic fields. Transformers are used to increase or decrease the alternating voltages in electric power applications. 26 libraries of the Electrical Engineering Solution of ConceptDraw DIAGRAM make your electrical diagramming simple, efficient, and effective. You can simply and quickly drop the ready-to-use objects from libraries into your document to create the electrical diagram.Electrical Symbols — Transformers and Windings *

Structured Systems Analysis and Design Method. SSADM with ConceptDraw DIAGRAM →

A waterfall model describes software development process as a sequence of phases that flow downwards. SSADM is one of the implementations of waterfall method. It’s easier to learn about structured systems analysis and design method (SSADM) with ConceptDraw DIAGRAM because this software has appropriate tools for creating data flow diagrams. You can use all the three main techniques of SSADM method with special tools and predesigned templates. This data flow diagram illustrates the Structured Systems Analysis and Design Method. This method method considers analysis, projecting and documenting of information systems. Data flow models are the most important elements of SSADM and data flow diagrams are usually used for their description. It includes the analysis and description of a system as well as visualization of possible issues.Structured Systems Analysis and Design Method
