Early testing is one of the seven software testing principles which implies that the testing process is started as early as possible.

How to prevent critical errors in a digital product and maintain your end users’ trust?

The answer is not that complicated: to involve in the product development all people who will be responsible for its quality in the future. Meaning, the QA team that is going to improve the quality of the product through various activities should get to the working process as soon as possible.
Clearly, it all depends on the project, software product, and methodology the whole team uses to develop it. But since most of the teams prefer Agile in their work, QA processes should take place far before the digital product is done.
Software product testing without executing the code is called static testing. Quality assurance teams, as well as other people in charge of the product’s future, should perform the static testing practices at the starting phase of the project.
What is checked during the static testing?
All the above-listed activities are performed by different QA team members depending on their expertise, skills, and professional experience.
What are the benefits of static testing and early introduction of the team to the testing process?

Summing  up

The biggest success of a software development team is the positive feedback from end-users who managed to solve some of their problems with your application.
To get such a result, right after the project initiation, the team has to think through all the activities helpful in making the digital product correspond to user expectations. To achieve that, your QA team has to check on every development stage, perform verification and validation, use all the advantages of static testing, execute all the necessary techniques of dynamic testing, and maintain effective communication during the project course.
The earlier we start testing the product and its development processes, the more polished it appears in front of the end-users. The fewer bugs users spot in the application, the higher is the trust for the company released it. And if the product functions as planned as corresponds to the user expectations ― that is the real success of the team and the whole company that worked on it.
