Block Diagrams

Block diagram is a diagram of such a system where the principal functions are depicted with the help of blocks. These blocks are usually connected by lines and such lines are known to be representing the relationships of the blocks.

Being widely used in engineering in electronic design, hardware design, software design and other kinds of engineering activity, Block diagrams are usually used for providing less detailed descriptions, being intended to clarify all the overall concepts having no concern for the details of implementation.

Making an analogy to the map-making world, any Block diagram is known to have a few similarities to a highway map. The major cities may be listed but the minor county roads and the city streets are not mentioned in this drawing.

Providing the ConceptDraw DIAGRAM diagramming and drawing software’s users with the pre-made templates, samples and stencil libraries full of vector elements, Block Diagrams solution can be used for drawing any needed Block diagram, Functional block diagram, or Block flow diagram.

Example 5: Block Diagram — Stages of Promise Issue

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the Block Diagrams Solution. An experienced user spent 10 minutes creating this sample.

This Block diagram sample illustrates the five stages of promise issue: measurement of expectation level in every segment, quality of service standards are determined for every segment, guarantee of conditions to redeem promises, formulation of promises (clear and examinable formal obligations), and finally fulfillment of obligations (delivery organization in concordance with determinate standards). The service quality constitutes the comparison of the expectations with performance and is one of the basic characteristics in a service industry because any business is successful only when it offers the high-quality service, satisfies the needs and expectations of clients, at this remaining economically competitive on the market. The increase of the service quality leads to an increase in economic competitiveness and can be achieved by means of a clear understanding of operational processes, improving them, quick and systematical identifying problems, setting actual and reliable service performance measures, measuring the satisfaction of customers and other performance outcomes.

Example 6: Block Diagram — Sources of Customer Satisfaction

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the Block Diagrams Solution. An experienced user spent 5 minutes creating this sample.

This sample shows the Block Diagram illustrating the sources of customer satisfaction. Any customer has some expectations before purchasing some product or service, which can be justified or not when the purchase was realized. A "customer satisfaction" is a key performance indicator within business and marketing, the term is widely used to reflect in what measure the products and services provided by the company meet the customers' expectations and maybe even surpass them. This term can be also considered as the percentage of customers, which reported experience with a company, specific products, or services surpass the specified satisfaction goals, to the customers' total number. Typically, in a competitive marketplace the customer satisfaction is the main indicator and a key element of business strategy because at the fields where the businesses compete for the clients, one can observe the great efforts making to attract the customers and withhold them by means of satisfying their needs and requirements.

Example 7: Block Diagram — Six Markets Model

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the Block Diagrams Solution. An experienced user spent 5 minutes creating this sample.

This Block diagram sample represents the Six market model, which was intended by three specialists from the Cranfield University in 1991 — Christopher, Payne, and Ballantyne, and determines the main kinds of the markets. The six markets are allocated and have the central position in relationship marketing: internal markets, recruitment markets, influencer markets, customer markets, referral markets, and supplier markets. The diagram visually depicts them as boxes around the middle "organization" box. The listed markets are different, with their own specialties, require the own explicit strategies and individual complex of marketing actions, so are allocated in separate categories. At the same time for the best success of an organization, it is recommended to realize the marketing activities at each of these markets. Thus, referral markets offer the best use of resources and represent the development and implementation of a marketing plan to stimulate referrals; supplier markets ensure a long-term conflict-free relationship and allow reducing costs at the improvement quality; influence markets include a wide range of sub-markets, etc.

Example 9: Block Diagram — Gap Model of Service Quality

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the Block Diagrams Solution. An experienced user spent 15 minutes creating this sample.

This Block diagram sample demonstrates the gap model or the service quality model developed by three people from Texas and North Carolina in 1985 — Parasuraman, Zeithaml, and Berry. Typically, the customers compare the achieved or experienced services with their own expectations and in this regard can happen different situations — when the expectations correspond to the reality and when not. In the last case, when the expected service and perceived one are unequal, the gap arises. This diagram represents five possible gaps that finally can cause unsuccessful delivery. The customer’s part of the diagram includes the perceived service and expected service that in its turn is determined by such factors as the word of mouth, personal needs, and past experience. The provider’s part of the diagram contains the management perceptions of consumer expectations, translation of perceptions into service quality specifications, service delivery including pre and post contacts, and external communications to consumers.

Example 10: Block Diagram — Customer Decision Making

This diagram was created in ConceptDraw DIAGRAM using the combination of libraries from the Block Diagrams Solution. An experienced user spent 10 minutes creating this sample.

This Block diagram sample shows the process of customers' decision making. It is a cognitive process the main goal of which is a solving of a problem in the best way, which supposes the thorough analysis of costs and their minimization at the maximization of benefits. The decision-making process leads to the choice of uniquely correct belief, direction, and sequence of actions from a few alternative possibilities. When the decision making concerns the everyday or usual situations, typically we don't even think about the process itself, don't fix at all steps of how it happens, but the making of key decisions in business, manufacturing and some other domains requires a thorough and serious approach to avoid the possible mistakes and provide the best solution in each situation indeed. The decision-making steps represented in this diagram will help you make the best decisions. They include problem recognition, information search, evaluation of alternatives, purchase, post-purchase evaluation, and divestment.

Block Diagrams

When using the term block diagram, we are referring to a whole sub-set of system diagrams, that use a series of blocks to represent components or actions, and connecting lines that show the relationship between those blocks. They are typically low-detail, providing an overview of a process without necessarily going into the specifics of implementation. A common example of a block diagram is a flowchart, used in many fields of business as a simple way of mapping a repeated process. Software and hardware designers use them to record the design process, network managers can show the relationships between electrical systems. The principle aim is to allow a critical view to be taken on the steps in a process or system — information on physical components or construction is left to schematic diagrams or blueprints.

Not all block diagrams are the same...

Although essentially a very simple format, a variety of shapes and connecting lines, and rules and actions pertaining to them, make the block diagram a versatile tool for many forms of industry. Another attraction is the ease with which they can be constructed — ConceptDraw DIAGRAM is an example of purpose built software designed with this form of process modeling in mind. The RapidDraw functionality found within creates new objects and their connectors in a single-click, creating an ever expanding tree as you work through the process.

Here are some examples of the sort of subject matter block diagrams can be useful for, and what style can be utilized in each case.


Quite a broad term, but you will find block diagrams used in all fields of business; at an abstract level, to describe customer intentions and management processes, to depictions of physical transactions such as product design and sales processes.

  • Business process modeling makes use flowcharts, control flow diagrams and data flow diagrams to show key parts of employee workflow.
  • Management diagrams include organizational charts, product lifecycles, and influence diagrams to make decisions and regulate the workforce.
  • Marketing diagrams involve decision trees, Porter's five forces models, and strategy maps to help identify and cater for customer routine.
  • Finance divisions rely on accounting and audit flowcharts to record and approbate account strategy.

The format of block diagrams lend themselves well to system and software modeling — often these sorts of processes involve logical, binary choice relationships with a finite number of permutations or possibilities. They can be used to identify or predict possible faults in a system.

  • To map internal software architecture, UML diagrams, data and function models, IDEF diagrams, or functional flow block diagrams can be used. Entity–relationship diagram (ERD), SDL diagrams, systems development life cycles (SDLC) are used to describe the relationship between components within a system.
  • To maintain safety and reliability standards, fault tree analysis diagrams are used to find any flaws in a product or process.
  • Electronic engineers who need to record complex relationships between electrical components will employ a functional block diagram.


As well as describing linear system processes and patterns of product lifecycles or customer behaviour, block diagrams can describe more free-form, creative diagrams for educational purposes — connecting thematic ideas and structuring concepts into a visual hierarchy for effective understanding and learning. Diagrams of this form, which can include mind maps and concept maps, bring a collaborative element to learning whereby subjects can be 'brainstormed' by people within a group.

  • Mind maps, concept maps and conceptual graphs are all concerned with learning through visualization techniques. Key areas of information regarding a subject are identified, and the diagram shows the relationship and relevance to each other.

  • Cycle visualization, or life cycle charts, are an effective way of showing repeated processes found in nature, weather cycles for example.
  • Tree diagrams express hierarchy within a subject; for instance the family tree of a monarchy, or branches of language and their subsequent dialects.

A multi — purpose solution

Not many software programs can claim to offer solutions for all the tasks mentioned, or are capable of such diverse functionality as to handle complex designs in a variety of formats. CS Odessa have devoted a number of years to ensuring that ConceptDraw DIAGRAM offers value in all these situations; for producing informative educational materials, professional looking system analysis, or constructing complex business processes, and much more besides.

A large portion of ConceptDraw Solution Park is devoted entirely to the principle of block diagrams in all its varied forms — each individual solution contains their own vector stencil libraries, full of task specific icons and templates, sample documents that provide a reference of the capabilities of the solution, as well as a host of associated help and how-to material (text and video).

A couple of key features separate ConceptDraw DIAGRAM from the crowd in terms of ease of use, and assistance when creating your block diagram. RapidDraw functionality allows the user to place objects on the page with a single click, automatically connecting to the previous shape, making the drawing process fluid and intuitive. The technology to connect objects has also been carefully considered — 'smart connectors' automatically choose the most efficient route between shapes, and realign themselves if objects are rearranged at any point.
