Interesting topic, but is the balloon popping an isolated incident or does it happen all the time? I do agree that more time will be needed by R&D to address this issue, but is this product already in the market? if so manufacturing engineering will also have to address this issue as well. There could be a mishap in materials or in production that caused this effect. Either way the project manager would have to modify the Gant chart to include the testing of this device and revise the corresponding documents.
