Slack is really effective for smaller teams to use as an internal communication platform. I think that it's still suitable even for companies of up to 500-1000 employees, but for larger teams it's less appropriate (or would require more aggressive organization, e.g. keeping channels protected and on an invite-only basis). It's really helpful for small team-to-small team communication too (like in our case where we create external channels to support POCs/business partnerships). It's not great for direct collaboration (e.g. it's hard to iterate on a project spec or a document together, directly in Slack) but it's well suited for conversational coordination, like planning meetings or asking informational questions.
Trello is great for cross-team communication and intra-team organization. It's simple to get setup, with flexible tools that give businesses control over how to make Trello work the best for them. It is an amazing platform for operations tracking, project management, and even organizing customer service requests for a smaller business.
Undoubtedly Slack’s search function is powerful but sometimes it is difficult to find specific messages or files in very active channels with high message volumes. This needs an improvement.
I have experienced notification issues on my phone. I am not receiving notifications and have missed important updates as a result. I tried uninstalling and reinstalling the app, but the problem still persists.
The Business Plus plan does not include support for data loss prevention or offline backup providers.
Slack sitll lacks in functionality. It's better than Skype for Business in many ways, but it is still another chat/message board app. It has limits in free version and paid versions. Also Windows app has errors that bother me, for example, I see number on one of my team's icons. It suggests that one of channels has unread messages; I check all channels - no unread messages, but that "1" still appears
I am very likely to renew Trello, because it doesn't cost anything to do so. I am also very likely to use Trello's upgraded features in the future because a lot of my team's data is stored on there and they have already gotten used to the platform. Trello is very easy for new team members to pick up, making the onboarding and usability very streamlined.
I am technology illiterate, it's my Achilles heel and this program is so easy to use. I have been utilizing it for a decade now. It makes organizing and prioritizing my life, my work, my business, my kids life, etc so much more manageable and without having to hold on to a bunch of into in my head. I can find it and locate it quickly and easily in Trello.
Yes, the app works 24/7. I don't even recall having any period that we could not use since the implementation. Even the maintenance periods are barely noticeable and our work is not impacted by it when it happens.
Slack is a soft app, we don't have many issues with it. I recall one or two people complaining about something during our usage period, but I didn't have a bad experience. When the app is slow, usually the problem is with my computer or my internet. The app works just fine.
Whenever I've had to troubleshoot an issue with Slack (which, to be honest, has not happened very often), their online documentation has been easy to locate, easy to understand, and effective in resolving my issue. Slack's ever-growing popularity also means that there's a large community of practice out there that can be depended upon.
I haven't had much need to contact their support because the product is easy to use and pretty bug-free. I did reach out to them about swimlanes and I was able to find the information I needed very quickly and it was thorough and accurate information about current functionality. I love that they use their own product. That's always a good sign.
For our small business, getting a few of us started well on Trello was the key, I think. As long as a couple of us were really comfortable with the interface, we could lead others and help them with any questions. From now on, anyone who works with us just naturally uses Trello for information sharing - it's just part of what we do.
I like Slack better than ClickUp, because I would spend 30-60 minutes a day updating my ClickUp tasks. The way ClickUp was used was very micromanaging. I billed by the hour, so I was willing to put in the time to alert the boss what tasks I was working on.
One of my jobs used Hive - I mostly just ran it in the background in case anyone messaged me. I did not use it often.
Our business ended up using Monday due to the holistic nature of the tool. It allows us to collaborate amongst teams and see the project as a whole easier. Trello is for personal usage and task management. I use Monday to organize my overarching needs, and then put specific tasks into Trello to stay organized.
Slack has been incredibly helpful in connecting various tech apps and ecosystems, creating a more streamlined and responsive process.
Slack has made it significantly easier to communicate with our team members across multiple time zones, creating a more engaging environment for our all-remote team.
It's been an essential tool for our onboarding team. We wouldn't be able to operate without it.
It's been a very affordable investment for our team as well since we still use the free version.
We have had a negative return in the fact that there aren't any reporting tools within the app. We have to spend time tracking certain elements manually.
