How we build web apps at IT Master Soft

If you want to hire our Yii development company, here is what our process looks like.

Step|01 Discovery

At this stage, we collect and produce essential information about a future product, identify the functional and non-functional requirements, estimate costs and plan project development. Not only does it help every team member to be on the same page, but it also allows the development team to choose a tech stack and define product architecture.

Step|02 Development

At this stage, we create the project roadmap that sets out the task-level details of a project. This helps the Yii developers to be in the know on what tasks they are working on and present results during demo sessions every two weeks.

Step|03 Launch

At this stage, the Yii development team ensures that all requirements are met, the project goals are accomplished and the desired outcome is produced. Once the product is free of bugs, the team prepares to get the project rolling.
