In anticipation of the High-Luminosity LHC (HL-LHC) era, the High Energy Physics (HEP) community faces considerable challenges in the evolving landscape of both experimental and computational domains. This paper explores the coordinated efforts led by the HEP Software Foundation (HSF) to address common challenges in software and computing. The HSF facilitates international collaboration and coordinates research and development through working groups. As the HL-LHC poses unprecedented data volumes and computational demands, the community adapts with advancements in hardware utilization, novel simulation techniques, and the adoption of array programming models. Additionally, the paper highlights the crucial role of the HSF in establishing a unified software training framework to meet the evolving needs of the HEP community.
