Monday.com can automatically set up graphs, tables and timelines that help you manage production schedules for free. It provides you with the ability to set up plans in a quick and easy manner and share it to people without much work needed. This can give you more time to focus on the actual tasks and less on setting everything up and distributing the plans and making sure everyone has them.
Trello.com allows you to create workspaces where you can invite people to the space and directly talk to them about managing production and schedules. This is useful as you can easily talk to people involved in production and share ideas. This also means that everyone involved can see what is being discussed and any questions/setbacks can be discussed during the planning on production schedules and not after.
They both make it easier to create, store and share plans on different tasks. The usefulness of creating production schedules online is that anyone can access it from anywhere as long as they have a device and there doesn't need to be face-to-face discussions that take time to plan. Limitations of the project management tools are that you are limited to what is available in the software. It also being online can mean it's harder to access, as physical copies and plans can be handed out to everyone, whilst online copies mean that you have to set up an account and have knowledge of how to navigate and use the websites, which is something potentially older generations working on a project may struggle with.
