Appropriate as a great alternative to MS Project. RationalPlan provides most of the features needed to develop and maintain mid-level complex schedules. Less Appropriate for large complex schedules of long duration. These can be a challenge due to Duration at top-level. It is also a challenge to generate reports for management - reporting feature is limited.

Slack is great for tracking commits to new coding projects. You can take parts of code that still need to be implemented later and easily search through the history of comments if there is something that goes wrong with a code commitment. It can be difficult for people that only like Teams to adjust to a new platform if you are using both to communicate.

Pros
Stand By Soft
  • Portfolio view is great to get a feel for how your programme is running at a glance and which areas possibly might require attention. The fact that you can customise your view by adding your own columns is another plus.
  • All project information in one tool is a big plus for me considering the amount of projects we run with. This really improves efficiency and saves me time. You have the ability to add documents to tasks, manage risks, email resources tasks due for projects they are assigned to(might need some refinement depending on your requirements), material db with costing etc.

Cons
Stand By Soft
  • Milestones should be a primary option instead of 0h to create one.

  • 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

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.

My rating was 7. Its intuitive interface and user-friendly features like channels, threads, and integrations make it excellent for team communication and onboarding. However, its usability is held back by the resource-intensive desktop app and cluttered feeling in large workspaces. The mobile app's performance and unreliable notifications have also been noted as weaknesses.

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.

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.

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.

RationalPlan is cost-effective and allows most users to prepare and manage their schedule. The software lacks comprehensive reporting and duration changes at the top level of a project.

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.
