Web Development Project Checklist

Web Development Project Checklist

A successful web development project requires more than writing code and publishing a website. Teams must gather requirements, define scope, plan the design, choose appropriate technologies, manage development, test functionality, address security, and verify that the final product meets stakeholder expectations.
