When a business analyst is creating a journey map, which assumptions are needed to get started?

When creating a journey map, the primary assumptions needed to get started are centered around understanding the purpose of the mapping effort and identifying the specific audience or customer segment on which the journey map will focus. Knowing "why you're doing it" provides clarity on the objectives and desired outcomes of the journey mapping process, which is crucial for guiding the analysis and ensuring it aligns with business goals. Identifying "who you're focusing on" allows the business analyst to tailor the map to the needs and experiences of that particular group, ensuring that the journey accurately reflects the customer's perspective.

The other options, while they may contain relevant information in the broader scope of project planning, do not directly address the core foundations needed for effective journey mapping. Project specifications, business needs, budget, and resources are important considerations but come into play after establishing the fundamental focus and intent of the journey mapping effort.
