E-Appointment System development for small business: Case Study of Jajja Chinta Hair Salon Using Shneiderman's Eight Golden Rules Theory

Jajja Chinta Hair Salon had relied for years on a paper-and-pencil scheduling system that often led to double-booked chairs or missed customer requests. To address these recurring headaches, the salon commissioned an E-Appointment System intended to modernise its booking workflow in a straightforward, entirely digital manner. At the heart of the initiative lay a clear goal, simplify scheduling, cut down on clerical errors, and ultimately improve the customer experience. Project aims therefore included gathering both user and technical requirements, building the platform accordingly, and later confirming that it worked as intended through thorough usability tests. Development was guided by an Adapted Waterfall Model and intentionally aligned with Shneiderman's Eight Golden Rules of Interface Design, fostering a coherent and predictable interface.
