Do you guys experience that issue too? What's a possible solution?
Interestingly it seems some teams from within a company use the tools more effectively. I think it’s largely about building a culture around sharing information. Confluence is the tool I’ve seen most commonly used. I don’t have strong opinions one way or the other about it, but would like to see what tools effective teams are using
The other important part of information sharing is the form factor. If you have a bunch of micro-services and command line apps that drive your company, I like writing this info into the Readme, and manual pages for the programs. Then the access to information is tied to the places where they are relevant, and you can build a sense of where information 'belongs' within the team.
I've seen confluence and google docs used for these things as well, and aside from things like 'company policies and hr' and 'setting up your computer for new devs' external documentation often becomes out of date with the software faster.
Aside from long-term information sharing like this, I think that email and irc are a pretty optimal setup for 'faster' communication. Email is good for sharing something with groups in a quick time-frame, and irc is good for immediate communication. I personally do not like Slack because it straddles many different time frames for communication, and many of the fun features lead to productivity killing noise. Scrolling back to find a months old message on slack when it could have been a searchable email is not fun. I feel like IRC and the limitations keep people from both jumping on every notification, while also preventing messages from being sent/recieved if a party is offline creates a logical switch from a quick message to an email. I've found that people don't fail to respond to old emails in the same way that a direct message might get lost in the noise of slack.
In the latter case, documentation is critical. The only way to manage this, regardless of what app or platform you use, is to create a culture of documentation. This means that EVERYONE is habituated to documenting what they're doing and taking responsibility for what gets documented.
I use Confluence at my day job but it drives me up the $(*&ing wall sometimes with dumb little things (the search function, arguably the single most important feature, STILL doesn't search naturally across titles and contents. You have to spell out a title exactly correctly in order to find it. WTF???).
I have used Nuclino for personal work and liked it a lot, though I don't know if it does enterprise-level stuff yet, like advanced team and permissions management. It might, haven't used it in a bit.
More importantly I believe is in having consensus on who plays the role of "director". Having a single voice that is universally acknowledged as the final say. A Mycroft Holmes type character so to speak. Creating the digital equivalent of a data curator and strategizer may be worth pursuing.
