I am currently project managing several projects, they are all one day long however I am struggling to set up project planning for them given that the projects are delivered in a single day. In that day, the requirements often do change in an adhoc way. In addition to this, there are multiple one day projects to project manage. I currently use Trello to project manage. If I use one Trello board it could lead to confusion, since the backlog items will be mixed up with different projects. If I create a new Trello board for each client/project, I feel that it will be excessive since the projects are typically one day long.
What is the best way to structure the project planning?
