If the discussion doesn’t produce a solution, then it should be tried again and again until it does because the project team is responsible for everything about the project. It’s important for them to have efficient communication with each other. If there are arguments and tensions between members, then it must be resolved by reminding people that they are on the same side and if they can’t work together, the team will suffer, which is why one person must suffer by being asked to leave. Risks should be minimized to very low numbers. I disagree that shortening the time frame is worth the increase in risk because, in this case, without sufficient time for the animal trials, the validity of the results will be questioned even though you may have yielded great results. Minimizing risks is always a must, which is why there is such a thing as the Quality Department. Shortening animal trials is not worth it, because even though you may have saved time, your findings could get rejected later on, and that will be much worse. Therefore, it’s better for you to put in the time and work early on so that the risk will be kept minimal. It’s not worth increasing risk because you will be worrying about it throughout the project if it’s so high that it will set your project back.
