Software engineering is a crucial element of every business. It is based on technical strategies to develop professional software applications through systematic and well-planned procedures. The software development procedure is categorized into three different processes: analysis, design, and implementation. When an enterprise focuses on software development, technical defects seem to be an inevitable part of the procedure. Resolving defects can take up a lot of resources such as time, money, and others. However, certain methods can help you determine defects and bring more visibility into software quality assurance. In one of their articles, Software Testing Help talks about the technique of Poka-Yoke, its usage, and how it can effectively help your business prevent mistakes.
Prevent Mistakes in Your Early Design
Poka-Yoke is a quality assurance process introduced by Shigeo Shingo. It efficiently reduces defects by detecting them at the early stage of the developmental phase. The implementation of Poka-Yoke initially started in manufacturing industries but is gradually becoming popular in software development. One of the examples to better understand Poka-Yoke is the Gmail attachment feature. When you write ‘please find attached file’ in the email but do not attach any file, a pop-up reminder says, ‘You have not attached any file. Do you still want to continue sending?’
Tips for Implementation
There are a few steps for Poka-Yoke implementation that can increase the visibility of your software quality assurance and defect detection:
- Construct all the probable scenarios and end-to-end test cases for the application.
- Evaluate all possible scenarios and figure out different ways under which the application can fail.
- Once you have a holistic understanding of the application’s failure probabilities, you can develop a Poka-Yoke technique to avoid those problems.
- After you have incorporated the Poka-Yoke technique in the software, use this technique for the list of tasks the team has to perform on every new release/build.
