The hallmarks of Tesla's vertical integration strategy do not include a network of dealerships that allows Tesla to sell directly to consumers and handle maintenance needs without relying on third parties that sometimes have competing priorities. investments in a "gigafactory" that manufactures the batteries that are essential for a long-lasting Tesla electric vehicle. fostering closer relationships between Tesla engineering and manufacturing departments to provide greater control over product design. research and development and rapid deployments of Tesla's control integration systems (creating control factors across its entire value chain). in-house manufacturing of key components and new parts that require frequent updates resulting in a shorter learning curve and more rapid new Tesla vehicle development
