Specification
Definition
Reference document describing the needs, objectives and constraints of a project. It serves as the basis for the contractual relationship between client and provider. A good specification covers functional requirements, technical aspects, budget and timeline.
Detailed explanation
The statement of work (SOW) is the most structuring scoping document of a digital project. Its quality directly determines the precision of quotes, the feasibility of the schedule and the ability to manage changes without budget overruns. A complete SOW covers: context and business objectives, functional scope (user features + back office), technical requirements (performance, security, accessibility, GDPR compliance), integration constraints (CRM, payment, analytics), the milestone schedule, the indicative budget and measurable success criteria. In 2026, AI-generated SOWs reduce 10-20 hours of manual drafting to 5 minutes from a brief.
Concrete example
B2C e-commerce project: the SOW lists 5 showcase pages, a catalogue of 200 products with variants, a cart + Stripe checkout, a client area, an order management admin, HubSpot CRM integration and on-page SEO compliant with Core Web Vitals. Budget: 12-18 k€, timeline: 8 weeks.
Common mistake
Drafting a vague one-page SOW ('a modern and responsive site') that allows every interpretation. Result: 3 incomparable quotes and a project that overruns by 40 % at launch.
