Final answer:
Self-service technologies may fail if they are poorly designed, not meeting customer needs, or due to early design decisions that later cause problems under specific conditions.
Step-by-step explanation:
Sometimes self-service technologies (SSTs) may not succeed as expected if they are poorly designed to meet the customers' needs. This could be due to poor design decisions made early in the development process. Self-service technologies may fail if they are poorly designed, Such decisions can act like time bombs, creating significant issues that only become apparent under certain conditions in the future. For self-service technologies to be effective, they must be user-friendly, efficient, and seamlessly integrated into the customer's experience.
