There's a bit of jargon that we use to describe the multi-stepped process of research and development: the spiral technique. The first step is creating the product, which is followed by evaluation, hunting for weaknesses, and finally risk assessment. Each one of those steps is likened to a single whorl on the spiral. At present, we're still at the first whorl.
目前先做出一個產品雛型，我們的行話稱為「spiral technique（螺旋技術）」，每個階段都要經過「做出產品、評估、找出缺點、風險分析」的步驟，每個階段走一圈，再走第二圈、第三圈、第四圈等，現在只進行到第一圈。
