Where to take into account information on development, if communication through instant messengers?

Question

Project management

I decided to look at the question from a different angle. If the task assignment system is not needed, tasks can also be assigned through the messenger.

Then what services, programs and methods would you use in order not to get confused with a bunch of information and to streamline everything. Save something for the future. For example narrow specialists. Or there is an assessment of the quality of a particular person in a particular role.

So, various kinds of information:
- People
- Projects, finances in them
- Demand

Answer 1

There is a contradiction in the original question: "the system for assigning tasks is not needed" vs "to organize everything"
Apparently I want to spread tasks across several tools:
1. assign tasks through the messenger
2. work with ordered information in the system
Therefore, the issue is solved by integrating one with the other, which often solved by bots.
