The challenges identified in the first workshop were general (see Table 4) and should affect development times of all BUCs and hence do not explain why a small percentage of BUC (albeit of different sizes) take so much longer than the average case (see Fig.5). Excluding the lead-times of BUCs that took longer than “X” units of time, which means about 30% of the BUCs, the average lead-time for the remaining BUCs was very close to the target of reducing lead-time by 50%. One hypothesis could be that by finding out the reasons why these 30% of the test cases take longer, and alleviating the reasons behind it we can achieve the target lead-time. And such potential improvement was not expected from addressing the top challenge the experts perceived as major hindrance to reaching the target lead-time
