Commissioning a ship or yard does not establish that its construction and testing are complete. Premature commissioning leaves problems to be discovered and repaired after a facility or vessel has nominally entered service. Germany's repeated design leaps add another delay when its infrastructure needs gradual improvement. The move from Scharnhorst to Bismarck illustrates how workers retain general skills such as welding but must learn unfamiliar components and assembly methods. Further changes would increase complexity and construction time again. Seeking greater fighting power in each ship could therefore deepen the numerical disadvantage that Germany hopes to overcome.

German shipyard readiness and the cost of changing designs
Commissioning ships and yards before testing is complete, then changing designs, reduces the output Germany can obtain from limited infrastructure.
