This document discusses whether a business needs a mobile app and what factors to consider. It details two case studies: a financial advisory organization that successfully launched an app with proper planning and testing, and a fashion ecommerce company whose rushed app failed due to a lack of planning and responsiveness to user feedback. The document provides a checklist for businesses to determine if an app makes sense, including whether it adds value, has a competitive advantage, sufficient budget, uses device capabilities, and has a committed team for ongoing support. Proper evaluation against these factors can help businesses decide if and how to develop a successful mobile app.
