First, some background:
I'm currently involved in a course which is based around a major group project. However, the end of the semester is coming up, and I honestly can't see this project becoming anything other than a massive trainwreck. (4 weeks to go, and people don't even have basic features working yet) Therefore, I'm planning on switching this course to pass/no credit, so I'm not killing myself at the end of the semester under the crunch/workload.
At my university, this is possible with just a signature from my academic advisor, so there isn't any need (from an administrative/paperwork perspective) to tell anyone that I did. However, I'm not sure who should be told from a political perspective. On the one hand, it might be a good idea to tell my fellow group members about this, but I don't want to add more fuel to the fire of an already failing project (I don't want them to feel like they've been abandoned). On the other hand, because pass/no credit means that I don't have nearly as much at stake for the project, they should probably know that this course won't be my top priority relative to the others that I am taking this semester. In addition, I don't believe that the project advisor would get told at any point in this process, unless I inform him of this. On the one hand, I feel like I shouldn't tell him how little confidence I have in this project (as it's one that he and the department are interested to see the success of), but on the other hand, I think he also deserves to know.
What would be the best way to deal with this situation?
