Development Process

At ADD W1, each product goes through a number of steps with a dedicated team monitoring and controlling each phase of development.

The process starts in the Research department, where the team of industry experts does a market study to find out about customer’s requirement for newer products while another team is constantly involved in the research to improve current products in the lineup.

After Research, the data is transferred to the team of engineers who first construct a 3D model of the component. The development team then construct a prototype which goes through a number of tests before finalizing. Once the prototype is tested, the information is passed on to the manufacturing team who develop the actual product.

The dedicated Quality Assurance Team follows a series of test on the final product to ensure its quality, function, and durability. If any inconsistency is found during the testing procedure, the whole process starts over again.

After the product is shipped, the Research team continually monitors the reviews and public testimonials to see what could be done further to offer the best service at ADD W1.
