I agree with you 100%. I find Iterative Prototyping to be the most effective methodology when designing and manufacturing a new product.
Below, if anyone is curious, I am describing the steps that makeup what is called Iterative Prototyping:
1. Concept Development:
This is the first stage and it involves defining the product's functionality, features, and target audience.
2. Design and Prototyping:
During this stage, you create a prototype to visualize and test the design.
3. Testing and Evaluation:
After the previous design phase, the prototype is tested with users and stakeholders to gather feedback on their usability, functionality, and design.
4. Refinement and Iteration:
After completion of the feedback collection, the design is refined, and new prototypes are created, repeating the testing and evaluation process.
5. Finalization and Manufacturing:
If a prototype qualifies as MVP (Minimum Viable Product), we are ready to manufacture the product.
Chadmirals of the Navy did iterative development with their ships
Originally they added Roosi missiles to this one class of Bri'ish ships that were the original Nilgiri class, build in India
Then they made a deshi derivative with a large hangar to hold 2x helicopters, this was the Godavari class
Then they made the country's first destroyer, with hull design inspired from Soviet vessels and carrying soviet missiles and radar wagera, this was the P15 Delhi class.
Navy has it's own design outfit called Warship Design Bureau, last i checked they hire smart nibbas from IIT Delhi itself and do design for all the warships
They also have their inhouse Electronics Engineering group called WESEE, to make raita deshi and imported from 5 places equipment work together flawlessly, your BEL wagera also do this but this is in-house Navy organization
Warship building is done mainly at MDL in Mumbai, but now major ships are also being built at GRSE Kolkata, ofc CSL made INS Vikrant because the other yards are smaller
These yards have heavy presence of Retired Navy officers of Commodore rank in managerial, I guess this application of the uniformed man's boot on the bottoms of chai-biskoot, union and strike pasand PSU workers gets them to actually work
They are also chill with collaborations and usage of stuff from other PSUs, like Indian navy ship's steel comes from SAIL, and many DRDO developed equipment is also used.
The other two services meanwhile do the bare minimum, it's either imports or screeching at DPSU or infinite trial-testing
