    Suitable if you are part of small to large scale companies or web-houses which have PHP developers and frontend engineers with some budgets. [Also suitable if] you or your client want to build a website that requires some features or uniqueness [and needs] some customization and freedom. Additionally suitable if you want this project to be DevOps based project or if the project requires very tight security and is inside of a closed network.

    Slack is ideal for Scrum and agile teams that need continuous communication during sprint planning, daily stand-ups, backlog refinement, testing, and retrospectives. Slack is well-suited for maintaining team knowledge through searchable conversations and dedicated channels, where experienced team members help onboard new QA analysts.

    Pros
    Portland Labs
    • As a dev, the Page object (coupled with page attributes, nav menus and page lists) makes structuring a website or web app a dream. The separation of page templates from page types also helps, the former being about layout while the latter is more conceptual.
    • As an admin, you pretty much have as much control as the developers of the site decide to give you.
    • The versioning system allows admins to roll changes back and work on changes before publishing them.
    • The permissions system is exceptionally powerful, allowing roles and/or individual users to be included or excluded from each permission.
    • The attributes system allows pages, files and users to be given custom properties of various types (e.g. text, image, colour).

    • Customer issues: Threads feature allows us to group a particular issue in a single thread and discuss within that thread. I can use the thread link to embed in JIRA ticket for tracking progress in JIRA (which is our details engineering tracking system).
    • Ability to add folder to Slack channel helps keep important information, documents easily accessible. e.g., we use this to keep a "ramp up" folder that can be used by any new joiner.
    • Global search is effective when I forget which group a particular message was in.

    Cons
    Portland Labs
    • Allow end users to clear cache when updating pages.
    • Needs a few more built in forms.
    • The CMS is not multilingual by default. Even though I managed to 'hack' it so, it would be nice to have it included.
    • It'd be nice to make use of custom PHP modules through shortcodes more straight forward. It seems the hooks are a bit contrived.

    • Would love a better integration with GitHub. For example, notifications when your PR is updated, when review is requested, @-mention in comments, etc.
    • Improved "Later" tab, for example the ability to create to-do lists or making the "Later" tab into a more powerful to-do list (annotate items with notes)
    • More powerful integrations, e.g. Google Calendar could render a calendar view within Slack, rather than sending the daily schedule

    Its a very solid, very consistent package that never lets you down or leaves you frustrated. It gets a 10/10 because its so much better than anything else currently available. It also gets a 10/10 because, even if not compared to others, it does not leave you wanting for features or functionality. It is an excellent piece of software that will answer almost every CMS need.

    To be more transparent, I give 10 because Slack serves our collaboration needs. It provide us a good platform for team communication relaying important update within the company, it has even mobile app where you can install in your phone to monitor any updates within that team that needs your immediate attention and intervention.

    Usability
    Portland Labs
    I have used it on over 30 projects in the past 3 years and it's still a pleasure to work in. Doesn't always have all the answers, no CMS does, but I still find it very easy to use from prototyping to working to final project. Also there is no problem working on a localhost then moving to a live site, like there is with WordPress. It's my go to app in my CMS quiver.

    Slack has good usability. Devs that are not familiar with the platform are able to jump into conversations and start sharing code and links within just minutes. Non developers are also able to understand the layout such as the Project Managers that are keeping the projects on track. We have not seen any tickets where employees are having trouble understanding Slack.

    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.

    Performance
    Portland Labs
    The site works extremely well, the front end flies, searches and form submissions are very fast indeed. The reason its a 9 not a ten? the back end can be a little slow at times, and this is unfair, because for the backend to be so amazing, it has to do a huge amount of work!

    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.

    Concrete5 is open-source and has an incredibly strong, polite, and supportive community. You can get an answer to nearly anything you want to do with Concrete5 by googling for it, searching the Concrete5 discussion forums or stack overflow, or posting your question to the forum. Members are very courteous and do not look down on those with less knowledge. And answers are always quick, informative, and supportive.

    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.

    Build off of an existing theme to speed up the creation of custom designed themed. Bootstrap is a good one but there are many others that are probably much simpler to build from than the Bootstrap one was. Make sure you host on a Unix/Linux server so you don't have to install PHP or MySQL separately. It's just smoother on those platforms.

    WordPress at the time was riddled with security breaches in the news and while Concrete5 was smaller (and therefore a smaller attack vector), after eleven years of use, Concrete5 has only had one published incident with an add-on that resolved within hours and with excellent communication. You can talk to the CEO and the CTO (or the rest of the team). They are very engaged and you're working with a small company of people who care, not a call-center with people just waiting to go home.

    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.

    Return on Investment
    Portland Labs
    • Concrete5 is the customer-facing side of our business. It's where we host the site that potential customers see before they choose to purchase and create an account with us. We are able to keep that site clean, user-friendly, and with a lot of available options for customers to interact with thanks to Concrete5
    • The ability to have multiple users and admins for the site means that we all members of our team can go in and create new content, fix or troubleshoot issues, and edit the site easily.
    • Our CRM isn't directly integrated with Concrete5, so when customers go to make a purchase with us, they have to leave our Concrete5 site.
