We’ve helped many of these customers adopt and scale agile using the Scaled Agile Framework® (SAFe®). In doing so, we met with Dean Leffingwell (creator of SAFe) and the team at Scaled Agile (SAI) to discuss some of our perceived challenges using SAFe in an engineering environment. We were looking for support for engineering work (requirements, designs, modeling, simulations, trade studies), different role names, support for supply chains, and inclusion of manufacturing and production — just to name a few. Our plan was to become a Scaled Agile partner and deliver SAFe-based training that 321 Gang would supplement with our expertise on engineering. At the same time, SAI was also looking for ways to serve the needs of the large system builders, and invited us to collaborate on a version of SAFe for Lean Systems Engineering…and so it was that SAFe LSE was born.
