  In April 2020, the 2019 and 2020 American Physical Society's Division of
Particles and Fields (APS DPF) Early Career Executive Committee (ECEC) members
were tasked with organizing the formation of a representative body for
High-Energy Physics (HEP) early career members for the Snowmass process by the
DPF Executive Committee. Here, we outline the structure we developed and the
process we followed to help provide context and guidance for future early
career Snowmass efforts. Our organization was composed of a cross-frontier
branch with committees on Inreach, Diversity Equity and Inclusion, Survey, and
Long Term Organizational Planning; in addition to the Frontier Coordination
branch, formed by committees responsible for liaising with each Frontier.
Throughout this document, the authors reflect on the triumphs and pitfalls of a
program created from nothing over a very short period of time, by people with
good intentions, who had no prior experience in building such an organization.
Through this exercise of reflecting, we sometimes find that we would recommend
a different path to our future selves. Insomuch as there are things to find
fault with, it is in the robustness of the systems we built and refined.
