Functional Design Specification

Your Needs

A functional design specification (FDS) or functional specification (FS) describes the technical solution which will be implemented to meet the project user requirements. This specification is the link between the user and the detailed engineering phase and provides the user and subsequent the project team with clear direction on system architectures, hardware platforms and software systems which will be used. The FDS also expands on the system functionality - taking high level functional requirements from the user requirements and expanding to specific functional details which will enable both software and hardware team to progress to detailed design and implementation.

Functional Design Specification (FDS)

Our Approach

Pilz can generate your Functional Design Specification, ensuring that all functionality is captured and manage stakeholder review including financial health check. You will have a primary source for all subsequent projects stages enabling technical and budget review and control. It will be generated to provide sufficient technical details for both hardware and software design teams to progress to detailed design

In general terms, the functional specification states what the proposed system is to do, whereas design is how the system is to be constructed to meet the functional specification. In writing it, Pilz will also some consideration of design issues must take place, to ensure a realistic system is specified. We ensure that the FDS becomes a milestone on the project plan both for initial generation and approval but also to cater for any project changes. 

What We Do

Pilz will take full ownership for the generation of the FDS, ensuring that all user requirements are captured . Once generated we will coordinate the distribution, review and approval process with all project stakeholders. We will also carry out a financial health check on your project prior to full FDS approval, thus will ensure that all technologies and technical solutions included fall within project budget boundaries. 

Your Benefit

This approach will provide you with a clearly defined Functional Design Specification which captures all user requirements, ensures all technical solution are within budget expectations and ensures full consistency across all project stakeholders and team members. This FDS will be the primary source of direction and clarity for all subsequent design stages.
