Model to estimate software projects

This project is capable of converting the text description of a software project into Excel model to calculate project cost and duration according to tasks, rates and risks:

It's clear how to estimate tasks in terms of developer efforts (back, front, devops).

And the roles like QA / PM are easier to tie with an empirical formula to the dev efforts. Not on per-task basis.

It seems logical that, say, QA's amount of work should be proportional to devs work, since QA needs to test all the features they deliver.
