Project management and communication apps tend to overlap but I find that no one app does all jobs perfectly. Trello and Hive have better Kanban functionality and so serve the "small task within a large project" paradigm better. Slack is by far the better communication tool but …

Slack is the first level of organization after Whatsapp/Telegram groups for teams. Slack is easier to adapt but more feature-limited and also more expensive than Discord. Slack is more well-suited for communication and less suited for task management than Trello. More focused …

Slack is vastly easier to use than Teams and far less convoluted. It also handles Trello and GitLab integrations in a way that is easy to read and digest (whereas Teams handles them in the most useless way possible). Every time I use Teams, something is broken or I can't find …

I selected Slack because it is the combination of the two that are mentioned above. In ClickUp you can manage the projects and tasks, in Skype you can communicate. Whereas Slack single-handedly handles both of these features, It manages your projects / tasks and allows you to …
Chose Slack
Slack's flexibility vs usability is well balanced. Slack does not require a time-sonsuming setup.
Chose Slack
Slack is a much better product, in my opinion! It’s much easier to use than other products, even though it may be similar enough. I would rather use it than any other product like Slack. Our team loves it and it integrates well with other apps like Asana or gmail.
Chose Slack
Honestly, we did some research and Slack was the one rated the best so we tried that first. We haven't gone back from it.

Before Slack, I used to use Telegram and Whatsapp, but they both were also my personal platform to chat with friends and family. This mix between personal and professional life was very damaging because it felt like I was always working. Slack gave me the possibility to feel …
Chose Slack
Slack is better at scaling, better for project management, and better for integrations than everything else we tried, including plain email.

For internal/team communications, Slack is by far the best app I've worked with. The channel system is very simple yet very intuitive. As a result, the app is extremely easy to get familiar with and use daily, even for members of our team who are not very tech-savvy. Slack is …

Slack is better in every way. Slack supports multiple workspaces in a single application. It allows to configure notification of each channels so that you receive messages that you need. Meetings with huddle is pretty awesome where we can have separate space for chat for that …
Chose Slack
Slack is just more superior in every way despite certain shortcomings. It is visually pleasing as well.

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.

Whatsapp - Slack is more professional
Chose Slack
Much more customization and ability to organize by topic rather than just by project.

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.

Chose Trello
Far superior to each in terms of flexibility, collaboration across organizations, and getting stuff done.

Microsoft Project is far to rigid for software development projects of today's day and age.

Trello is the best way to give all of your project ideas and display your thoughts in a stream. Even if this app does not have a calendar, you can still estimate the time [of completion] of your project by adding up the tame it'll take to finish every task. Something that Slack
Chose Trello
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.
Chose Trello
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.
Chose Trello
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.

Trello is more in-depth and task-driven, whereas 15Five is more accountable and has personal weekly goals and accomplishments. Trello can be divided up to allow others to do the listed task, and all employees work together to accomplish and complete each required ticket/card …

I also use Whatsapp chat as a task management tool. Whatsapp group chat is very convenient for assigning tasks and making follow-ups. Trello currently lacks here. Whatsapp chat is also way more handy and user-friendly than Trello, because of its better interface and engagement. …

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.

Compared to others, Trello is definitely one of the most economical options which makes it more appealing to freelancers. It is also more simple and visually engaging which makes it intuitively easy to use. However, it lacks advanced features such as timeline management, …

I selected Trello because even if it's similar to a lot of competitors, it is the cheaper but mainly it is the simplest and quickest software.
Chose Trello
We selected Trello as it was easy to setup...only a few minutes. We looked at MS Planner as part of our Teams integration but that did not have nearly enough labels for our purposes.

Trello is very easy to use. It is an intuitive software that does not require prior learning to take advantage of it. Asana has a complicated interface, not very intuitive and difficult to use. Trello has an intuitive interface that I like very much.

Being free and SaaS, it requires very little setup in comparison. It's very simplistic but is just enough.
Chose Trello
Trello is visually more appealing and easier to understand by simply looking at it. When it comes to sharing my board with others, they can quickly (within seconds) see our progress, which gets them excited and buys me more momentum. Asana is great, but it takes a little bit of …

I would say Trello is very well suited for my team's needs as we are relatively small in size but frequently scale up based on the project's size and needs. We tend to use it at a basic level for organizing internal tasks and to-dos, but also develop large complicated boards …

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…

JIRA is mainly focused on tech projects that have independent stages of productions. JIRA makes it easier to prioritize things and Trello lacks complexity on that feature. Trello is easier to use for the non-sophisticated user and JIRA has a worse user experience. Also, Trello …

Trello by far has the easiest interface to use and understand. The 'no-frills' approach compared to other tools makes this a clear winner in the realm of tracking and organizing ideas. Where it lacks in more robust features found in other software, it makes up for in an …

Trello is the most intuitive tool I have ever known. I only used it for 15 minutes and I knew how to manage the basics of the board and the options.

Slack is well suited as another tool in our toolbelt to find answers to common questions and to find resources. it is less appropriate to be used to collaborate on a project in terms of being a project management tool

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
  • Can create channels for small, medium, or even bigger team to relay important information/updates and whatnots.
  • You can do one-on-one (huddle feature) if you're on-boarding a member.
  • A platform that can be collaborated with other platform. Example a CRM to be linked with Slack for easier comms relay.
  • The best feature for me so far is that you can mention a team member so he/she won't missed an important message you sent.
  • You can directly message about anyone within the company.

  • 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
Salesforce
  • 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.

Atlassian
  • 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)

Slack is wonderful, it is a tool that changed our perspective and our way to work. We used to use another one, which was purely and sorely designed to messages. Slack provides us that possibility and more, all the other functions that we daily use in our work routine, not to mention the fact that Slack has a wonderful design and it's really easy to use and adapt.

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.

Applications can cause slowdown when onboarding because of the learning curve. Slack is user friendly and very easy to teach new users how to navigate the app. Installation is fairly quick, which also saves a lot of time when setting up new computers and users

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.

Slack is vastly easier to use than Teams and far less convoluted. It also handles Trello and GitLab integrations in a way that is easy to read and digest (whereas Teams handles them in the most useless way possible). Every time I use Teams, something is broken or I can't find things. But Slack is on the ball. Always easy to use and to search. Plus better emoji syntax (um, Microsoft, people put stuff in parenthesis all the time; that doesn't mean they want it to be emojis). Anyway, I'd choose Slack over Teams any day, if given the option.

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.

Return on Investment
Salesforce
  • I don't have hard numbers, but I can't imagine the level of mistakes that would go uncaught without the easy ability of multiple people being alerted to look at something in real time.
  • Efficiency of communicating this way takes a lot of slog out of email, more focus on more important conversations and tasks
  • It is on managers to define expectations on how long it should take someone to respond on Slack; it can feel immediate, which can be distracting to deeper work

  • 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.
