The Statement of Work (SOW) specifies the work tasks to be performed by a supplier,
including an organisational entity internal to an organization. The SOW may specify the
methods to be used to ensure that these tasks have been performed to the specified
standard. Reference herein to a “supplier” should be interpreted to include reference to any
entity tasked with providing a service.
The SOW may be used in the acquisition of a service alone, or a system and associated
services such as installation and testing. The SOW specifies the deliverable services. It
does not specify the system - this is specified in a System Specification which may be
invoked by the SOW. It does not specify any data deliverables - these are specified in a
Contract Data Requirements List (CDRL) or equivalent which may be invoked by the SOW,
and by associated Data Item Descriptions (DIDs) or equivalent which are invoked by the
CDRL. The SOW may specify services “internal” to the contract or project in order to
control, for risk reduction purposes, the way in which the tasks are performed by the
This Data Item Description (DID) may be cited in a contract or any other form of agreement,
Statement of Requirement (SOR), Statement of Work (SOW), a Contract Data
Requirements List (CDRL), or within a standard invoked by a SOR or SOW.
This DID incorporates and adopts some non-copyrighted material contained in MIL-HDBK-245D, Preparation of Statement of Work, issued by the United States Government.
