Statement of Work (SOW)
Also known as: SOW
A statement of work (SOW) is a document that defines the specific deliverables, activities, timelines and acceptance criteria for a piece of work under a contract.
An SOW sits beneath a broader agreement such as a master service agreement and spells out exactly what will be done for a particular engagement — the scope, milestones, deliverables, standards and how completion will be judged. It turns a general relationship into a concrete, measurable set of obligations for both buyer and supplier.
A precise SOW is the best defence against scope creep and disputes. When deliverables, timelines and acceptance criteria are ambiguous, work drifts and invoices become contentious. For services and project-based procurement in Malaysia, a well-written SOW makes performance easy to verify and payment easy to justify.
