One of the manufacturing projects that my team works on at my company, was delayed because of an issue in the biology department. The cell biology department had an incubator that was contaminated that killed all of the cells that were needed to manufacture the diagnostic tests that we make. This pushes us back about a month because of all the cleaning and the re-growing process of the cells. This was time that was only partially able to be made back by overtime spent by the biology and the manufacturing department. Luckily, 2 weeks of slack time was built in so that we could have a little bit of room for error and the costumer didn’t mind too much, or so they say.
