In the world of open source solutions - there are many different applications, programs and everything interesting. But if there is no such 100% solution that would suit you? That's right, you need to submit an idea. Service for joint, open development of ideas (in the form of schemes, requirements, etc.), descriptions of those. parameters, organization of requirements, and subsequent development (*github o_0) with goodies, in the form of documentation generation (like Bizagi), organization of "Wishlist" by priorities, creation of schemes, architecture, in the process of description and development.
Would such a service be of interest to the community? If there is something similar, please share. Github - after all, more for developers.
