True. The Development Team is self-organizing and they have the freedom to change their engineering practices as they deem necessary. This is in line with the principles of the Agile Manifesto which emphasizes the importance of responding to change over following a plan. The team is responsible for implementing the most effective processes to deliver the product, and they have the flexibility to adapt to new challenges and circumstances. However, any changes they make should align with the overall goals and values of the organization to ensure that they are delivering value to the customer.
