During a project that I was working on our team missed a milestone for our execution of animal trials. We had gone through the protocols for conducting the trial, however there was an error in the paper work required for approval of the animal trial and the testing facility. This error delayed us in our trial by about two weeks and increased our budget as the trial had to be resubmitted and expedited, costing more than normal. Our project manager had accounted for project slack in this scenario because he had encountered similar problems in other projects where testing facilities contracted were an issue, therefore this setback did not affect us significantly. In order to assure that no further time was wasted we personally went to the testing facility where the trial was being conducted, in order to ensure the protocol written was followed correctly. This is usually not common practice, however we could not risk delaying the timeline further, and were cleared by the contracting facility to be present for the trial. It turned out to be a good decision because there was some confusion on the protocol and I believe that it would not have been followed correctly if we were not present at the site.
