Flowcharts hold excessive significance, proving a momentous approach, especially in displaying a framework of a plan execution, computer program working, a business process like recruitment or onboarding, financial planning like budget management, etc. Additionally, flow diagrams are incredibly instrumental in solving problems, such as finding a bottleneck in the system, catering to resource deficiencies, and more.
Most flowcharts work on the principle of yes/no, applying two alternative conditions to the encountered situation, whether true or false. Yes-no flowcharts fall in the category of those conditional flowcharts which suppose to find solutions using two alternative paths. Given this background, we have composed a thorough guide about yes-no flow diagrams, explaining the concept with some illustrative yes-no flowchart templates.
1. What Is Meant by a Yes-No Flowchart?
A yes-no flowchart is a type of flowchart which executes two variant responses by adopting different paths. Containing a decision box, yes-no flowcharts provide two alternative solutions to the given condition, either to solve a problem or make a decision. Yes-no process flowcharts authenticate a piece of information as a solution to confirm whether it's true or not in the encountered situation.
For example, if you have to travel abroad for touring, you would apply the condition "Whether the tickets are available for the tour"; if the tour tickets are available (Yes), you can take a flight abroad. On the other hand, if the tickets are not available, you first need to book the flight tickets.
Another example for comprehending the yes and no flowchart concept is a program in which you need to print the prime numbers from a given list: 1, 2, 3, 4, 5, 6, 7. The applied condition for this situation would be "Whether the given number is a prime number or not". The program will testify each time by applying the statement of yes and no to check whether the upcoming number is prime or even.
2. Examples of Yes or No Flowchart Templates
A visualized scenario is necessary to acquire a crystal-clear perception of the abstract idea. The following yes or no flowchart template examples from EdrawMax will assist you in developing an enhanced understanding of when and where a yes-no flowchart should be employed:

The above yes-no flowchart comprises a detailed procedure to calculate the temperature value in different units when a specific unit value is given. The first condition is whether your temperature unit is Fahrenheit; you can find the value of C from f by applying the formula (F-32)x5/9. If the temperature value is not f but C, you can find f through (Cx9/5)+32. Similarly, if K is given, you can calculate C through the formula K-273.
If you own a content management system account and want to grow your business, you can build your website to enhance your online reach. There are certain conditions to be eminent, such as your website should be updated, & responsive; your web content should also be engaging.
The above template is an SDL diagram pertaining to a system's front-end and back-end development. The first step involves composing a product description, followed by the structure review. After reviewing, the front-end and back-end development process starts, and the testing environment is provided to the system.
The test results are displayed to the production team; if the system is defective, the defects are removed by repeating the developmental processes. In contrast, if the system is flawless, it becomes worth operating now, and the team arranges its post-production maintenance resources.
The above flowchart instills greeting manners regarding saying hi if you don't know the person's name. You have different options to averse saying hi, such as fleeing, wearing sunglasses, pretending to be on call, and so on. However, if you can't perform any of these activities, it is better to say hi to the encountered individual without taking his name.
To determine whether a number is a prime number, you can divide it by two and check to see if a whole number remains; if you get a whole number, the given number cannot be a prime number.
The above-presented algorithm has been designed to comprehend this mechanism. The method begins by giving S a value of 12, followed by entering the P; the P value is raised by one if P is an even number. The new value of S is S-1 if the new value of P is a prime and is less than five.

4. Conclusion
Yes or no flowcharts are the most basic-level flowcharts that operate on two variant conditions to arrive at a conclusion. Such types of flowcharts utilize logic to verify which of the two solutions is the correct one; being instrumental in multiple domains, they are extensively employed in spotlighting the underlying processes, solving the problems, making informed decisions, developing strategies, describing complex processes, etc.
Considering these aspects, we comprehensively explained yes-no flowcharts along with reference to their pictorial examples to amplify your perception. Moreover, we presented an in-depth procedure to constitute, configure, and export your yes-no flow diagrams using EdrawMax.
