The price for any development services is formed based on the complexity of the task. For complexity we use Fibonacci numbers (1 story point, 2 sp, 3 sp, 5 sp, 8 sp, 13 sp, 21 sp). Thus, the simplest tasks that take less than two hours of work are estimated at 1 sp; tasks that require a full-time average developer at the middle level - 3 sp, 5 sp; a task that will require about a week of work, as well as its testing - 13 sp, 21 sp

Price for 1 sp is $100The price for any development services is formed based on the complexity of the task, time it will take as well as the risks and uncertainties associated with the task. This unit of measure is called storypoint (sp). The price of 1 sp is $100. Storypoints are not directly tied to hours, but in our experience, on average, 1 sp might be equal to 2-3 hours of work. We use Fibonacci numbers(1 story point, 2 sp, 3 sp, 5 sp, 8 sp, 13 sp, 21 sp). This allows us to make an accurate assessment, taking into account all the factors that go into the concept of a storypoint.

Storypoints allow us to avoid estimation bias. Estimation in hours of development is less accurate and can vary greatly due to the difference in time spent on the same task by developers of different levels.

Thus, storypoints system lets us take into account all the factors influencing the final result of the development. The formed price reflects the totality of resources required to complete the task. This estimation is the closest to reality and does not depend on the developer working on the task or the project manager.

The stages that each task goes through sprint:
