Project termination can occur for various reasons such as technical or financial failure, changes in needs or priorities, or budget constraints. When a project is terminated, it impacts individuals and the organization. A terminated project requires closure while minimizing trauma through open communication. Methods of project termination include removing resources, integrating the project, or squeezing the budget. Examples of terminated NASA projects include Apollo missions 18-20 and programs such as X-33 due to cost and technical issues.
