What challenges did John face when introducing parameterization into the YAML templates?
assistant
Parameterization required careful planning to ensure flexibility without compromising simplicity. John had to identify which parameters were essential (e.g., target environments, feature flags) and design templates that could adapt to diverse requirements. Testing was crucial to validate that parameterized templates worked seamlessly across projects. John overcame parameterization challenges by carefully designing flexible yet simple templates and validating them through testing.
