A standard approach

TDC Need software helps you express your right questioning as of the beginning of a project, not taking yet into account the solutions, thanks to a functional and comprehensive expression of needs .
The Functional Analysis approach used is based on European and French standards EN 1325-1, NF X50-151, and on the APTE (R) method.
TDC Need is used as a support to the design process, the value analysis or supplier consulting, along with ready to dispatch documentation, automatically generated. Standardizing and ordering the capitalized data into Functional Specifications also pertain to its features.

Evolution management

Traceability is handled for every individual data: use phase, function, performance criteria, etc. Thanks to the access to all the dates, authors and contents of the changes, you can, for instance, filter all data not being changed since the latest project review or list up the successive evolutions of a particular task.

Improving your responsiveness

Data projector based, the TDC Need work sessions facilitate the working group reflection, with the help of additional tools, such as: the Pieuvre (R), exhaustivity matrix, crossed sortout. Direct functional tree changes offer enhanced responsiveness. More than genuine documentation publishing, characterization charts and 'to do actions' can also be shared on the TDC intranet Portal, thus improving efficiency between two work sessions.

Maintaining data consistency

The various tools you will use share the data all along the design process: external (FPS) and internal (FBD-FAC) functional analysis, Design FMEA, Process FMEA, Control Plan, Flow Diagram, fault tree analysis, ... ensuring the methodology data consistency.


Several deliveries can be automatically generated upon the end of the worksession: Functional specifications as design input data, FPS, purchase specifications, machine specifications, value analysis, validation / qualification plans, etc.

Approach and terminology customizing: validity control, environment diagram, discovery matrix, tree, characterization type, crossed sort out

Graphic filter: all changes in the study since or at a given date, etc.

MS Word direct paper printouts (style sheets) and XML reports.

Special Copy/paste (tree branch and its characterization..)

Value analysis: compares cost dispatching with importance weight given by the user and so identify satisfaction improvement ways based on various product scenarii (options, versioning).

Link to requirement management

Terminology is explained through regulation abstracts.

Function, performance criteria, ... library management.

Multilingual management of the study data.
Interfaces available in: French, English, German, Spanish, Portuguese.


Facilitator annotations: comments on the workgroup life, 'to do' tasks or links to files or URL.

Tasks input and function characterization done by workgroup members, off meeting.

"Environment Diagram" graphic tool of the APTE® methodology
