Launching a website without a specification document (CDC) often leads to doubled costs and major delays. This document turns your ideas into a clear plan, limits misunderstandings with developers, and acts as a “contract” between you and the agency: it specifies what you want, why, and how to achieve it. Without a CDC, a large share of projects exceed budget and deadlines (up to 70% according to studies), whereas a well-structured CDC significantly reduces risks (around 50%) by framing expectations, deliverables, and scope.
