Case Study: WingMail - Photo to Postal Mail Communications App
Initial Ideation
Concept Development:
The idea for WingMail emerged from a recognition of the communication barriers faced by prisoners and their families. Traditional mail is often slow and cumbersome, leading to emotional distress for families trying to stay connected with their loved ones. The concept was to create an app that simplifies and expedites this process by allowing users to send photos and messages directly from their smartphones, which are then printed and delivered to prisoners.
Market Research:
Extensive research was conducted to understand the needs and challenges of both prisoners and their families. Interviews and surveys were carried out with stakeholders, including prison authorities, families, and former inmates. Key insights highlighted the need for security, ease of use, and reliability in such an app.
