Final answer:
In Scrum projects, we plan to "learn as we go" because it allows for an evolutionary approach, saves time, and creates a better relationship between developers and customers.
Step-by-step explanation:
In Scrum projects, we plan to "learn as we go" because it allows for an evolutionary approach where a better solution can emerge over time (option a). It is also time-consuming and impractical to analyze and plan everything at the beginning of a project (option b). By learning as we go, we can adapt and make adjustments based on the feedback and needs of the customer representatives, which ultimately leads to a better relationship between the developers and the customer (option d).
