Final answer:
In Phase 1 of the international planning process, host-country constraints and initial considerations of product adaptations are analyzed, while budgets, promotions, and action plans are developed in subsequent phases.
Step-by-step explanation:
During Phase 1 of the international planning process, companies analyze host-country constraints, along with other preliminary considerations such as market potential and competitive landscape.
Although not explicitly detailed in the phases, understanding product adaptations may also form part of the initial analysis to determine how a company’s product might fit into the global market. However, other aspects like budgets, promotions, and action programs are typically developed in later phases after the initial analysis has confirmed the market's potential and identified specific entry strategies and necessary adaptations.
