Avantages:

And I have really enjoyed the community-centred interests people put into ensuring your challenges are taken care of is really encouraging. I love Slack for this singular effort.

Inconvénients:

The only drawback is that we just have too many avenues where we connect and so Slack just got lost with all the other programs and didn't become a priority. This is why we no longer use it.

Logiciel très complet et agréable pour travailler en équipe

5,0 l’année dernière

Avantages:

L’expérience utilisateur a été très bien pensée. J’aime bien la facilité de prise en main de l’application. On a tout d'une application de messagerie instantanée en temps réel. Le partage de fichiers et les intégrations avec des applications clés qui automatisent les processus importants permettent de gérer un pourcentage élevé de tâches en un seul endroit. J'aime également la possibilité que nous offre Slack d’analyser les donnés de nos discussions.

Inconvénients:

Parfois, sur l'application mobile, les notifications arrivent un peu en retard. À part ce petit souci, je pense que tout est parfait !

Un très bon outil de communication

5,0 il y a 2 ans

Commentaires: Nous utilisons cette outils principalement pour les discussions écrites en plus d'outils comme skype. Nous avons créés des canaux par projet et mis en place des commandes personnalisées afin d'automatiser certaines tâches.

Avantages:

L'outil est très pratique à l'utilisation. Il permet en période de télétravail de continuer à communiquer avec l'équipe facilement. La version gratuite est certes limitée mais fonctionne très bien. Aucune panne n'est encore venue gêner l'utilisation du logiciel. Fonctionne aussi bien en natif qu'en version Web. Il est customisable facilement.

Inconvénients:

La version gratuite amène quelques limitations : - L'assignation et customisation des groupes est limitée - La limite de message fait que si les utilisateurs sont nombreux, les messages disparaissent vite. N'utilisant pas le forfait payant, il est normal que nous ayons ces limitations. Il manque des canaux oraux.

Super outil de communication

5,0 il y a 2 ans

Commentaires: Il est facile et amusant à utiliser, facile à configurer et, dans l'ensemble, c'est un outil puissant pour les personnes qui recherchent ce type d'application de messagerie.
Ce n'est pas pour tout le monde, mais ça vaut vraiment la peine d'avoir cet outil au moins une fois dans s carrière pour se rendre compte de sa facilité.

Avantages:

J'aime la facilité d'utilisation de Slack. On a tout d'une application de messagerie instantanée, il a plus de fonctionnalités et il est facile à utiliser. On peut lancer un appel avez zoom rapidement. Les rappelles de taches ou de reunion sont appréciables. On peut rattraper une discussion là où nous l'avons laisser nous pouvons donc suivre le file de d'une discussion rapidement Esthétique outil

Inconvénients:

Je ne vois pas trop de défaut à ce produit, si ce n'est des améliorations: - Faciliter l'utilisation des #. -La fonction d'appel vidéo, une vue en grille serait idéale pour les appels de groupe par exemple. -Améliorer le copier coller . Pas trop de défaut à signaler mis à part ces 3 petites chose

Tchat professionnel de qualité

5,0 il y a 2 ans

Commentaires: Le tchat nous permet de discuter aisément à distance (encore plus en télétravail depuis quelques temps).

Avantages:

Slack permet de discuter au sein de l'entreprise très facilement grâce aux channels publics et aux conversations privés. Il est possible de faire des rappels automatiques. Il est possible de partager simplement son écran et de faire des conférences visio.

Inconvénients:

Depuis une des dernières MAJ, il n'y a plus le lien qui permet d'accéder au dossier de téléchargement de fichiers. Mais c'est vraiment un détail car Slack est vraiment bien.

The only way to communicate within a team

5,0 il y a 2 mois Nouveau

Commentaires: I use it for all manners of communication with my team - from quick huddles when we get stuck and need a rubber ducky moment, to bigger team meetings. We have groups for smaller teams to collaborate in, we have fun channels to blow off steam, and we even use it for the food train organization.

Avantages:

It is easy to use and feels natural. For us coming from Discord or IRC, it is very intuitive to understand how to use it without any learning curve whatsoever. Slack helps me connect with coworkers, share project updates, send cat photos to my team, send random funny quotes, gifs, reactions, all of it still in a very professional application that handles all of my communication needs.

Inconvénients:

Slack sometimes becomes too much, but it is easy to mute it to focus on work so this is easily solveable.

Best Tool for Team Management and Coordination

5,0 il y a 3 mois

Commentaires: Overall I love to use it and provided it has the support of integration with almost all of my tools it works as notification engine too which is one of the awesome parts of this tool.

Avantages:

Slack is my daily used software for all the team meetings and sharing work details. I like it has all the features built-in that are necessary for an enterprise team management from sharing of files and chatting to video or audio conferencing.

Inconvénients:

The support team is slow in case of any problem tho hardly we face any issue with this software it's highly reliable and one of the best things I use on daily basis.

Slack is the ultimate team-discourse application

5,0 le mois dernier Nouveau

Commentaires: Slack has drastically increased our workplace productivity, especially by promoting communication between those that work in the office, and those that work at home.

Avantages:

Slack manages to maintain a comfortable work-home boundary with the introduction of different channels. The ability to create "private" channels within a workspace also helps to build community. File sharing is convenient and easy to understand, and the notification settings are remarkable.

Inconvénients:

Often if a notification is received on one device (i.e. laptop) it will not always push to another (i.e. phone)

Avantages:

Slack offers a complete centralized solution for project management and team messaging.

Inconvénients:

On large teams, the sheer amount of channels can be overwhelming. But Slack does offer ways to tidy things up.

One of the best communication tools

5,0 il y a 2 mois Nouveau

Commentaires: there are many features I like about slack like huddle features especially and chatting features, user profile,

Avantages:

I like the most about slack is this. 1. support third-party plugins like Figma, google calendar, google drive, todo, Jira, GitHub notifier, and many more. 2. Search is fast compared to other chat communication tools. 3. huddle features for connecting people with screen sharing.

Inconvénients:

need to improve the user interface. that looks like too much is provided but we do not need all things. so increases complexity. so, give inside setting on-off features for what is not required as default features.

Experience after 3 years of useing Slack

5,0 il y a 2 jours Nouveau

Commentaires: Slack demonstrates a strong scientific link, particularly when used for internal company communication. Slack is also user-friendly, with an easy-to-use layout and a login interaction with LinkedIn. Furthermore, as compared to other programs, this application is quite light on computers and phones.

Avantages:

It is highly handy for this application to combine login with Linkin, which helps to improve connection possibilities while eliminating many redundant login processes. Also, because Slack is cross-platform (desktop, Android, and iOS), everyone in my firm can communicate with one another regardless of device. Furthermore, the possibility to connect to other storage services like Dropbox, Google Drive, GitHub... Slack's free plan allows users to save up to 10,000 messages exchanged by the team, 5GB of storage, and connect up to 5 additional carrier services.

Inconvénients:

The storage of messages only takes place for a short time and it is necessary to update the paid application versions to use more features. This makes the free version quite limited and unpopular for long-term storage of information.

Slack: The Tool That Sent Email Conversations Packing

5,0 il y a 4 semaines Nouveau

Commentaires: The main problems we're solving is to do with communication. Since all our team members are working from the comforts of their homes, we need a place to sync all the time. Slack provides that platform. It's the place we convene and dismiss. Slack feels like home now. Everybody's connected and readily available.

Avantages:

Slack is one of the tools I didn't care about until I learned about it. And ever since I did, I've come to appreciate its awesomeness. Working in a SaaS company, with a work-from-home culture, software like Slack feels like an Elixr. There are no hassles when it comes to communication... No email. Simply interact and get the job done. The feature I like the most is its Huddle feature for 2-way audio-based communication. Overall, the software is pretty easy to use. Another cool feature is putting out status (in terms of availability). Whenever I'm AFK for lunch, I put on my availability status, just in case someone decides to reach out. It might sound small, but it works wonders when you're working from home. Another cool feature is that the messages are saved no matter how long back you or some team member (who might have even left) posted it. And there are so many integrations possible, which makes it ever so interesting. Playing trivia games daily is our team's one chance to engage in a virtual fun activity space, which is kind of fun. Also, I've had the opportunity to meet so many people in the various Slack communities. I mean there are other channels, but the quality of the network is definitely right up there.

Inconvénients:

Even though Slack is an awesome tool, there's still some scope for improvement here. For instance, even though I mentioned Huddle as one of my favorite features, I've found some of my teammates complaining about not being able to connect, which gets a bit frustrating. Apart from that, there are features to set reminders and put other commands to help manage things better. I wish there was some kind of tutorial available to learn these things earlier. Another thing I wish was there was the ability to put out memes. I mean, I get it... it's a serious kind of platform, but sometimes memes just get the job done. I'd like to conclude by saying that it'd be cool if we could delete our messages (maybe within 5 mins of posting) too apart from just being able to edit them.

Slack - An incredibly popular workplace messaging app

5,0 il y a 2 mois Nouveau

Commentaires: Over the past year and a half, I have used Slack as my primary communication and productivity tool. I have been impressed with the platform's ease of use and the breadth of features it offers to its users. I have also been impressed with the number of Slack integrations available, which have increased my productivity and efficiency. I have also been impressed with the amount of support Slack provides its users, which has allowed me to focus on my work rather than troubleshooting problems. Initially as a tool to help me communicate and collaborate with my team and later as a place to share and discuss content with the world. I’ve been impressed with the ease of use and the power of the platform. Over time, I’ve found that Slack has become a key part of how I communicate and share information. I can get a lot done in Slack, but there are still some things that keep me on the platform instead of other tools.

Avantages:

1. Slack is an incredibly popular workplace messaging app that’s used by millions of people every day. It’s a great tool for keeping groups together, sharing information, and collaborating 2. It is used by over 13 million daily active users and has been valued at over $2.8 billion. Slack is an excellent tool for team communication 3.Slack is a messaging app that lets you send messages, files, and emojis to coworkers and clients. It’s a great way to communicate and collaborate 4. Slack is one of the most popular workplace communication platforms, used by more than one-quarter of companies with more than half a billion daily active users. The platform is loved by some, hated by others, and many are still undecided about its usefulness 5. When most people think of communication, they think of email. But when it comes to team communication, email doesn’t always work. It can be hard to keep in touch with a single platform, and it’s easy for the conversation to get derailed or get lost in the shuffle. But now there’s another option: Slack. 6. It has many advantages, such as the ability to share files and work together on large files in the same workspace

Inconvénients:

1. The biggest disadvantage of using Slack is that you can’t customize it to suit your team’s needs. For example, you can’t customize the design of your channel or change the background color. 2. It's great for broadcasting what's happening in your team, but it's not a good place to brainstorm, share confidential information, or make decisions. It's also difficult to get individual attention when you need it.

Slack is excellent and I think it should be used by every business

5,0 il y a 2 mois

Commentaires: Mostly for quick and efficient communication across teams and with colleagues in other countries. I also use it frequently for managing access to my Google Drive, for managing cross-team projects through Google Drive, for tracking Jira tickets and updates and much more. We use it for team meetings, sharing each other's screens when required. We also use it for cross-team discussion about issues and to create a history of previous issues and collaboration that is easy to check.

Avantages:

So many things: firstly, how quick and easy it is to communicate across teams and countries within my organisation. It is so much faster than sending an email and so much easier to attach documents, manage document access, and more. It's really quick to search for a specific issue across slack channels. It's great to be able to make new channels about specific issues and to be able to tag colleagues in those channels. It's really well-integrated into my google drive which makes my life so much easier. I like that you can grant access to a document simply by posting a link to it in a channel, rather than manually granting everyone access. I like being able to send myself messages as reminders. I like being able to call people through it. I like being able to reply in thread. It creates a great and easy-to-access record of all sorts of issues and collaborations, in a way that is far more streamlined than through email. I like being able to add colleagues to channels when required. It is great for managing Jira tickets. I also like being able to quote messages. Slack is brilliant!

Inconvénients:

Just some small things: it would be nice to get a proper notification when something is posted in select channels. Currently I only get notified if I'm tagged in a message in a channel, and when I'm working it's difficult to constantly keep an eye on the channels to see if there's an important message that I haven't been tagged in. I also find it annoying that if I make a group chat, all previous messages disappear if I add someone new. When I message myself for notes, I find it frustrating that the messages aren't more clearly separated - it becomes quite a mess in there. I would like to get a notification every time someone posts in a thread I've posted in - this doesn't seem to always happen. Finally, I would like the emojis to be easier to type, rather than having to open up the emojis every time I want to add one, it would be nice if it were easier to add two at once.

Slack: The Ultimate Collaboration and Task-Completion Platform

4,0 il y a 3 mois

Commentaires: Slack suits large enterprises with several departments and teams who communicate regularly. It's fast and informal. Slack is easy to use on a smartphone, making it helpful for traveling. It's less suitable for siloed or formalized teams.

Avantages:

Slack rocks. We use many channels to keep consumer, internal, and tech support communications distinct. This is a fast and simple communication tool that my [SENSITIVE CONTENT] might use to ask for my help with a customer or team procedure. It's also important to "document" queries and replies for future reference. We utilize Slack to connect with our staff, form department/project groups, and incorporate clients. It keeps us organized and simplifies communication. Connecting Slack to Apps helps with file sharing, client feedback, and document management.

Inconvénients:

Slack calls/huddles don't terminate immediately. When someone calls using Slack, direct join call option is confused; it states join huddle and call attend choice doesn't function effectively. No direct connection for entering the Slack meeting.

New Age Communication Tool

4,0 il y a 3 mois

Commentaires: Good, good, gooood. Thanks to Slack that enabled us to improve our communication and achieve our set goals. Instead of email, we communicate through Slack and it gets a better result.

Avantages:

I like the cool features and amazing functionality of Slack. It makes file sharing, meetings, and team collaboration so easy that anybody can do it without putting much effort. Since we started using Slack, we have shifted almost all of our daily communication to this one-in-solution. Our team members always get in touch with each other using the real-time chat feature. We have created different channels for different teams that helps us manage the work in a more organized way. File sharing is a big part of our work routine and Slack does it professionally. Integration with other applications such as Google Drive and Dropbox is another added feature. I have the PC version and also installed the phone application that helps me keep in contact with the team so effortlessly.

Inconvénients:

The contacts tab design can use some improvement. It's all cramped up. The drop-down arrows with the channel sometimes hide the contacts and that really annoys me. I wish there was a different user interface with more ease of use.

Commentaires: I love slack, but I think its value is for fast internal communication. Not a lot for video or document sharing.

Avantages:

Is the best communication tool. Easy to use, you can have a lot of channels and bots and it seems like the info won't get lost because it is all organized.

Inconvénients:

The free version is great and I wouldn't see why to pay for the use, since you probably have free options in case you really must (in your package with the email provider or tools like Telegram, discord, etc)

Slack revolutionized our workspace communication

5,0 il y a 3 mois

Commentaires: I needed some time to see the benefits of Slack, coming from an email-only workplace. I soon started to appreciate the benefit of the communication style Slack made possible, and I think it is hard to imagine achieving the same level of efficiency without Slack.

Avantages:

Slack is different from the communication and chat tools we used previously. With Slack, we could create channels for every part of the project and only add people who are stakeholders in the area. Communication in these channels is visible to all their members, making information sharing the default in team communication. Direct Messages are still possible for private or secret data transfer. This channel style is also quite useful when creating alerts and notifications. All people can see all Notifications in one place and may communicate about them in the "threads" of the message. Slack also introduced "Threads" to allow for sub-communication about any message in the channel in order not to block the flow of conversation in the channel.

Inconvénients:

It doesn't support RTL languages and sometimes uploading files takes a very long time.
