About Functional Analysis / System Analysis

Functional analysis derives functions and subfunctions of a system and its elements. Functions are needed it in DFMEA to identify potential failure modes and are used during conceptual design to identify new solutions.

Identify functions of a system

Functional analysis returns a function tree.

How to insert the Functional Analysis / System Analysis component

The Functional Analysis / System Analysis template can be used to start new projects or to extend existing projects. Please read chapter "The Templates" to learn more about how to start new projects.

In order to extend your project:

  1. 1
    Activate the Home Ribbon Home Ribbon
  2. 2
    Click the Add Tool button on the Home ribbon
  3. 3
    Click the Functional Analysis / System Analysis icon in the template catalog

In order to find the Functional Analysis / System Analysis component within the template catalog, you have to choose a cycle name on the first line of the screen and a phase name at the left of the screen. The Functional Analysis / System Analysis component is located in this cycle/phase combinations:

  • DFSS DMADV: ANALYZE
  • DFSS IDOV: DESIGN
.

Tree of design elements with functions and design options. Links to QFD 3. Can be used to populate a Morphological Table

Use the insert buttons in the Home ribbon to create the system structure or to add a function to a system element or a possible failure to a function.

Drag lines from a sub-function to a parent function. You can also drag lines between possible failures in order to define the cause-failure-effect relation needed for FMEA and Fault Tree Analysis.

System Analysis and Concepts

The system analysis component can show both the generic setup of the system and one or more actual implementation approaches.

Use the layer control below the project browser to switch between the system configuration and the different implementation concepts.

  • At first, only system configuration will be available. Use the Morphological Box component to create new implementation concepts. For the generic system analysis (system configuration activated), use generic descriptions for the parts, e.g. motor instead of dc motor 25W.

  • Changing the active concept will only show the actual parts used by the selected concepts and hide the generic descriptions.
