Implementation of the Waterfall Method in Website Design as a Digital Promotion Media CV. Prima Printing

Abstract

Operating out of Bangko, CV. Prima Printing is a digital-printing enterprise that until now has promoted its services mainly through social-media pages and word-of-mouth referrals, while every order it receives is still logged by hand, an approach that invites recording errors and slows the whole workflow. As a result, product and service details are not consistently documented, which in turn narrows the firm’s market reach. This study sets out to build a promotional website for CV. Prima Printing by following the stages of the Waterfall model, namely requirement gathering, system design, coding, testing, and post-release maintenance. The platform runs on native PHP together with a MySQL database and is hosted through Hostinger. Core capabilities include a database-backed product catalog, guest-checkout ordering that skips account registration, design-file uploads, automatic cost estimates, self-service order tracking, down-payment confirmation, a buyer-seller chat feature, visitor ratings of the site, and a two-tier control panel for admin and super-admin roles. Safeguards such as upload validation, password hashing, and protection against SQL injection were also built in. Functional testing under the black-box approach covered 19 modules across 66 scenarios, all of which passed without a single failure. The resulting website is expected to give CV. Prima Printing an effective digital promotional channel that presents complete product information, streamlines ordering, and widens its market reach.
