Quality Assurance

Our commitment to quality

We understand the importance of delivering a product that not only meets your specific requirements but also exceeds their expectations in terms of quality and functionality. Our team of experienced software development engineers is dedicated to ensuring that every project we undertake is completed to the highest standards. We take pride in our attention to detail and our commitment to quality, which sets us apart from our competitors.

UI Kit

UI kit includes all types of site content: buttons in different states, icons, checkboxes, menus, breadcrumbs, etc., and the way how pictures and photos will look in the final product. It will free more time to focus on the most critical aspects of your designs and create reusable, consistent, and maintainable UI components

Continuous integration/continuous delivery(deployment)

CI/CD is a method to frequently deliver app versions by introducing automation into the app development. CI/CD is a solution to the problems that new code integration can cause for development and operations teams (aka “integration hell”).

Version Control

With version control, every change made to the code is tracked. This allows you to see the entire history of who changed what at any given time — and roll back to an earlier version if necessary.


At the beginning of each project in Yellow, we define a GitFlow that’ll be specific to the exact project. It’s a simple and effective way to support continuous deployment and constant releases.

Code Review

Regular code review helps to maintain high standards of quality and enhances the overall performance of the code. How does code review work? When one team member has finished working on an issue, another one looks through the code and considers questions like “Are there any obvious logic errors in the code?” or “Do existing tests need to be rewritten to account for changes in the code?”

Unit Testing

“Unit test” is a testing method by which individual units of source code are tested to determine if they are ready to use.


at NCS, we work with a number of software development models.

Scrum is one of the most popular management strategies housed within the Agile methodology. Scrum is based on predefined sprints that look to improve team efficiency in cyclical development cycles.


Unlike Scrum, Kanban doesn’t work with predefined iterations (e.g. sprints). Instead, Kanban focuses on process visualization. With the help of a Kanban board, the team sorts out all the tasks they have on a project, indicates their priority, and assigns responsibilities.


Waterfall methodology is a process in which the phases of the project flow downward. The waterfall model requires that you move from one project phase to another only once that phase has been fully completed.
