Sequence of Operation/User Requirements Specification (URS)

 
This document defines all the functions required from the system to meet the requirements of the customer. Customers supply us with anything from a vague process description to a detailed document. Whatever the case may be, we help finalize the User Requirements.

Functional Requirements Specification (FRS)

This document defines how the User Requirements will be met. We take whatever up-front definition we get from our customers and drill into the gory details of each of the smallest portions of the operation to develop an extremely detailed control system definition - the Functional Specification. We plug our past controls experiences into this document – We ask very detailed questions. The result is a document that can be submitted and reviewed by our customers. This establishes an excellent starting point for programming.
