If you do web programming, code integration with your remote team, and/or software development that requires real-time monitoring of development progress, monday dev is an excellent tool for this. Like its base platform, Monday.com, monday dev is developed and attempts to integrate into a very "new era" organizational system of digital whiteboards, only now focused more on productivity and helping developers to be comfortable in remote work.
Feature Flags are well suited for apps which are being developed across numerous teams in order to extend and basically enable/disable whatever areas of the app you want. It's not really necessary for an individual developer or perhaps even a single team of developers, depending.
While monday dev is an excellent ally to organize and work in harmony with your team, there are still certain important aspects that need to be improved. They are minor, but if corrected, they will help improve the user experience when using it.
Monday is better than Jobber, as it gives you a place to see where all the jobs are and what the current status is. Everyone in the company can go to and see that view. It's not dependent on the status of the employee. Excel is much more technical and requires much more work to set up.
We still utilize Git as our source control system but Feature Flags allow us to use Git in a less complex and more efficient way for our development needs.
I would say a large ROI considering the reduction in branching and merging we need to perform and also the ability to use common, up to date code across teams. There's a lot of shared code we make use of, particularly with identity and authentication and our entire identity platform which is essentially used by each feature.
