Functional
Design Specification (FDS)
Sustema integrated solutions culture places great emphasis
on the initial engineering design phase of any project.
The Functional Design Specification (FDS) is a concise,
detailed and well-written, comprehensive document, which
details all aspects of the project and is a major factor
in ensuring that a project is successfully executed.
This results in a well-designed and documented system.
The FDS represents the most important document in the
project cycle as it “defines" the user's requirements
into functional definitions of how the system is to
operate and perform.
User Requirement Specifications (URS) differ from client
to client. They can range from a brief description of
the process to a detailed technical document. Sustema’s
design engineers, therefore, have to prepare a descriptive
design document, (the FDS), which details every feature
of the system to be provided. The FDS then forms an
integral component of the contract between Sustema
and the client. Therefore any variations that occur
in the project can be clearly identified, thereby keeping
both parties informed with a clear understanding of
the original scope of supply.
An important function of the FDS is to provide a document
from which the systems performance can be gauged. Our
customers can accept, or reject a system, as fully meeting
their requirements when we have tested it against the
FDS.
This is achieved by inviting the customer to a full
factory acceptance test (FAT). |
