小瑞正設法讓某個旅遊應用程式打入東南亞的新市場。在考慮應如何將應用程式設計與付款方式本地化時，她應該先採取什麼動作？

The correct answer is "進行市場調查" (Conduct market research). Before making any significant changes to an app's design or payment methods for a new market, it's crucial to understand the local preferences, cultural nuances, common payment systems, and user behavior. Market research provides the data needed to make informed decisions about localization, ensuring the app resonates with the target audience and offers convenient payment options. "展開全面重建應用程式的工作" (Initiate a complete app rebuild) is premature and potentially wasteful without prior research. "讓應用程式開發作業進入改版停止期" (Put app development on a redesign freeze) is counterproductive, as it halts progress without gathering necessary information. "進行競爭對手問卷調查" (Conduct a competitor questionnaire survey) is a component of market research, but not the comprehensive first step needed to understand the broader market and user needs.
