Slack was so simple to start using--super easy integrations with Jira, Sharepoint/OneDrive, and our PM tools--that it was a no-brainer. The video was glitchy, especially for any users who had iffy upload speeds (which isn't Slack's fault entirely, but they did not have as many …

Simply put, Slack is a much more robust and comprehensive tool.

Before in the organization, we used Google Hangouts, but it was not well integrated into our team. The functionalities were very limited and could not cover our needs. The advice was very messy and we failed to meet the productivity objectives we had.

I have used Basecamp in the past, but have not evaluated in the last 3 years. At the time I began using slack, Basecamp was overkill for my needs, and didn't provide as strong of a mobile experience.

Without a doubt, Trello is the easy one of the bunch to use. It is beautiful to look at and easy to interact with. It does for sure lack some features that other software has like Wrike, Basecamp, and Slack. But for simple smooth task management, it is the go-to.

Trello is another must product for any business like Slack. Both allow a company to have collaborative efforts and increase efficiency which means happier employees and more money for businesses.

I have been able to use the free version of Trello for many years and for the free version, this platform offers incredible value. I have not yet found such value in other free versions of similar platforms. This platform is also very easy to use as a first time user.

We do use and like Jura but this can be used with it and we do. It isn’t just Jira light. It’s feature packed but available and understandable to the masses. Anybody can learn this where Jira may take more time. The price is better and it’s just better looking visually honestly.

Trello fills a specific function for simple project tracking. It is better to use this tool as a complement to your workflow instead of a replacement. Anything more complicated should be moved to more adept tools, and communication should be moved to a more focused platform. …

I like Trello because it is simple and easy to use. I also like that the free version can do what I need it to do. Other options, such as LeanKit, JIRA, and ServiceNow are expensive and complicated. Trello does what I need it to do without being overly complicated. JIRA and Serv…

I think Slack works really well in office settings, or even for any group of people who need an easy way to communicate with each other through organized channels. It may not be the best for those who intend to use it as a social media type app, it is more geared towards business use.

It is well suited to my job requirements as I bring employees in, and I help offboard them as well. This tool helps me when I need to make sure all items are completed by a certain time frame, so I would say it holds us accountable. Someone who doesn't manage a group of people may not find this as useful when dealing with others but could use it for their own accountability when needing to track their accomplishments.

Pros
Salesforce
  • Automated Notifications: Integrated tools like Jira, Trello, and Google Drive to receive automated notifications and updates directly in Slack, improving visibility and efficiency within the team
  • Message Encryption: Slack encrypts the messages in transit and at rest, ensuring the security and privacy of sensitive information and making our IT team's life much easier.
  • Reminder Bots: We used Slackbot to set reminders, automate follow-up actions, and provided information based on user queries.
  • SurveyMonkey Integration: Integrated our Slack with SurveyMonkey to distribute surveys and collect feedback from team members, streamlining the feedback-gathering process which was a huge support to our HR and Admin team.

  • It helps make various workspaces. Each workspace can be used for a different set of task management and can be shared with the people involved.
  • Creating task lists. We can create various task lists, the list title could be the status of the task, for example, In progress, approval, completed, etc. You can slide your task cards from one list title to another.
  • Trello cards have a huge set of features like adding the heading and description of the task, you can also attach certain associated links and documents to the cards as well.

Cons

  • The only thing I can think of is that it is easy to create too many channels. This has more to do with the team using Slack and less to do with Slack itself. maybe some direction on Slack's part on how best to utilize channels would be helpful.

  • Allow tables as content for comment or description in Cards
  • Assign priority to certain cards (easy for sorting)
  • Create an open invite link for others to join/view the Trello board, without edit rights (so people don't need to install/use Trello if they want a quick glance on what's going on)

As useful as Slack has become within our company, I feel fairly confident we will continue to use Slack as a communication tool. They continue to improve their software and add value to its use within our office. Customer service delivers, which is an absolute must. Looking forward to how they improve.

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.

Usability
Salesforce
As long as you use the basic chat features and nothing more, it really is super easy to understand and use. Once you want to take advantage of some of the more advanced features and capabilities, that's when things get complicated. Anyone who has use SMS or a chat program before will be able to figure out the basics though, so rolling this out should be relatively straightforward and not required exhaustive training. Teaching chat etiquette is something else though.

Overall, Trello is a great tool to use. It's very user-friendly, very powerful and we've set it up to work well for our team. I've recommended it to others who need something free or very cheap and it's worked well for them too. If you're wanting something with more muscle, then I'd suggest looking at either monday.com or Airtable.

I've never had to contact support for Slack which is a great testament to its ease and use. Adding people outside of the organization takes a little getting used to, but ultimately allows for greater collaboration between FTE and contractors. There is no clear alternative to this software, so it's the best we can do for now.

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.

Trello is easy for a non-technical person to use. Other management systems, like MS Project, frighten away less computer-savvy users. I've found this to be instrumental in getting volunteers to agree to step in and get fully involved with projects--particularly those that might span the entire year or involve many different pieces to completion.

  • Trello keeps me organized, focused, and on track. I could filter the Trello board to only see my issues and understand what I needed to work on and when.
  • Trello helped our team implement an agile structure. It's a very simple kanban method of viewing all of your team's tasks and statuses. You can completely customize the columns to your team's specific workflow and create tags relevant to your work.
  • Trello helps reduce unnecessary communications between teams. When I want to request translations, I simply create a card on the localization Trello board -- no need to directly message anyone on the team, and I can watch the status of the card change from "in progress" to "in review" to "translated," all without having to directly ask for updates.
