What documentation does a consultant create for a project?

The project consultant is usually responsible for preparing and maintaining the following documentation:

• Technical specifications (TS) — description of system requirements and functionality.
• Business requirements — documenting the client's needs and project goals.
• Regulations and instructions — descriptions of business processes and rules for working with the system.
• User documentation — manuals and guides for end-users.
• Analysis and testing reports — results of compliance checks against system requirements.

This documentation helps ensure understanding between the client, developers, and users, and also serves as a basis for system implementation and support.
