Quando un importante cambio di direzione progettuale ha reso superfluo il lavoro precedente, ATK ha raccolto la sfida passando da un processo classico a quello digitale.
“When NASA came to us and said they wanted to change direction, it was an eye-opener to discover that we had made a significant investment that suddenly had little to no value. Despite the fact that the SLS boosters were based on the Ares design, the differences were large enough that they would have required starting from scratch by constructing a new prototype, new spreadsheet, and new drawings. Very little from the previous project was reusable. We were also conscious that our previous methods were very labor-intensive, so when we discovered that our next project would be equal in magnitude yet would have to be done with less manpower, we realized we needed to improve our process – and do it quickly. We decided to develop a digital approach that was less labor-intensive and would enable us to more easily adapt to change,” afferma Nathan Holyoak, ingegnere dei processi PLM per ATK.
