Why did Germany's late start in tank manufacturing give it an advantage during World War II?

Germany’s late start in tank manufacturing provided a significant strategic advantage because it allowed the German army to enter World War II without being burdened by large inventories of obsolete equipment.1

While nations like France, Great Britain, and the Soviet Union were hampered by masses of aging tanks, Germany began developing its panzer series from scratch in the 1930s. This allowed the Wehrmacht to focus on modern designs and, more importantly, to organize its forces into specialized panzer divisions rather than dispersing tanks among infantry and cavalry units. By integrating these massed formations with motorized artillery, radio communications, and blitzkrieg doctrine, Germany created a highly efficient and mobile fighting force that was qualitatively superior to the fragmented and often outdated armoured assets of its opponents at the start of the war.1234
