Likelihood to Recommend

Opal

I honestly cannot recommend this tool enough. Opal is such a valuable tool for brand content creators and there is nothing like it available. If you're serious about content marketing and have a need to find ways to collaborate, plan and provide more visibility among teams, then Opal really is the only way to go. One more thing that's not being mentioned: The tool is simply amazing but it's only as amazing is the team behind the tool. Their customer support and willingness to quickly be in touch when needed is a key feature within itself. Seriously, such a good team of people.

Slack

When there's a team that spans time zones and continents, Slack is the perfect tool for communication & collaboration. It houses a workplace directory, so any employee can be searched for by name. Sending a direct message to any individual in the company is as simple as finding their name, then typing a message & hitting send! Essentially, it's a hub for all communication -- individual, team, and company-wide announcements can be quickly & easily disseminated using Slack.

Pros

Opal

  • Content planning: you can look at one asset and see how it is being used across multiple channels by multiple teams.
  • Content collaboration: it is really easy to see what other people and teams are contributing to an asset, or how they are using it. We can also duplicate content that was created by another team to use as a starting point in our own content collaboration.
  • High level/big picture overview: Opal allows us to see content that is being created, planned and scheduled very easily; it goes beyond social content (which we can also see in Sprinklr) to show us content created across multiple channels.

Slack

  • Slack is a solid chat tool that works across a variety of platforms, with a very low barrier for entry: new users can be invited via email, and can use web-based, desktop, or mobile versions of the application.
  • Slack has really captured the zeitgeist of digital culture, including strong support for customizing look and feel (including custom emojis), and a plethora of integrations with popular web-based tools, including Pivotal Tracker and GitHub on the productive side, and Giphy.com on the fun side.
  • Slack continues to refine and improve their product, with new features being rolled out just about every month.
  • Slack offers a great value in their free version of the app, with most of the tool's functionality available for no cost.

Cons

Opal

  • No publishing capabilities, for the most part.
  • No analytics tie-ins.
  • Rather pricey.
  • Requires someone to really manage the structure in order to keep the tool organized and use it effectively. When this is done right, though, it's worthwhile.

Slack

  • The sorting of channels - it's a bit confusing, could be better sorted, it would make it easier to search and make it more agile.
  • Search - It could also improve, it is not bad, but in some cases (rare) it is difficult to find the term that you want.
  • Heavy performance in other operating systems - At least in Linux, Slack seems to do a little more machine performance than when it is used on a computer running Windows.

We've been thoroughly impressed and hence will renew the application for sure as it's meeting and at times exceeding our exceptions in getting things done. A surely shot application that is recommended for a startup, a small company and also very large enterprise and also for multiple open source projects.
Given the points stated, it's a renew for us.

Everything just works. I think the navigation and usability is quite intuitive. I have never had to look up any information or google how to use a feature of Slack (both in the desktop form and on the mobile app). I've never heard any complaints from our other employees either. I have been asked to remind people how to set up reminders, ironically. Although that itself is really simple too (you type "/remind" and then the reminder details).

I don't need to be very technical to use the Slack or to integrate tools into Slack. Adding an app (integration) is seamless and the platform walks me through the process. I can communicate with my colleagues quickly either with chat or by using the call feature to phone them. If I ever have a product question, I can quickly go to one of our product channels and search for related questions or pose a question that our experts monitor. These features have made me more effective in my day and in managing my customer base

You get for what you paid for. Opal has more features

Slack

Atlassian actually ended up shutting down HipChat and partnering with Slack, but these are areas in which I think Slack outperformed HipChat:
  • Better UX
  • Ability to edit messages once they've been sent
  • More functionalities and integrations with different tools
  • Ability to share channels with other organizations
  • Better mobile app
  • Dark mode

Return on Investment

Opal

  • Opal allows for more discipline in marketing as teams are better aligned on messaging and big moments.
  • Opal cuts down on communication breakdowns and mistakes, which in the end leads to more happy customers.
  • I think Opal provides the team with more confidence as everyone is on the same page. With everything in one place rather than communications being lost in emails, etc., everyone is more efficient and can work knowing that there is one source of truth.

Slack

  • I believe this has increased productivity amongst the team in that we can get immediate responses to issues and questions, allowing us to have a better continuous flow of work
  • Having an easy to use tool like this speeds up on boarding, as new team members can easily learn. They also will have access to all existing resources within the tool
  • We have been able to customize communication groups to include those appropriate, eliminating unnecessary noise regarding areas not relevant to particular team members.
