Overview
| Property | Value |
|---|---|
| Type ID | function |
| Sort Order | 8 |
| Domain | Design (Design space) |
| Managed In | Function documents per subsystem (e.g., SYS-001-Functions, SUB-001-Functions) |
| ISO Standard | AIAG/VDA FMEA Handbook |
Custom Fields
Function work items have no custom fields. They use only standard Polarion fields.Standard Fields
| Field | Type | Description |
|---|---|---|
title | String | Name of the function (e.g., “Deliver fluid at prescribed rate”) |
description | Rich text | Detailed description of the operational capability |
status | Enum (status) | Lifecycle state: Draft through Obsolete |
severity | Enum (severity) | General severity classification |
priority | Enum (priority) | Priority level |
Link Roles
Functions participate in three key link roles that position them at the center of the design-to-risk traceability chain:| Link Role | Direction | Connected Type | Purpose |
|---|---|---|---|
allocatedTo | Forward | systemElement | Identifies which system element provides this function |
assesses | Reverse (from failureMode) | failureMode | Failure modes that analyze how this function can fail |
assesses | Reverse (from riskRecord) | riskRecord | Risk records that assess this function (HARA context) |
DFMEA Context
In the DFMEA risksheet, functions serve as Level 1 (top-level grouping) items. Each function is linked via anitemLink column using the assesses link role. The DFMEA sheet uses a queryFactory to filter available functions by the document’s subsystem, ensuring subsystem-scoped analysis:
Document Organization
Functions are organized into per-subsystem documents following a consistent naming pattern:| Document | Space | Functions |
|---|---|---|
| SYS-001-Functions | Design | System-level functions |
| SUB-001-Functions | Design | Fluid Pumping & Housing functions |
| SUB-002-Functions | Design | Control & Processing functions |
| SUB-003-Functions | Design | User Interface functions |
| SUB-004-Functions | Design | Sensing & Monitoring functions |
| SUB-005-Functions | Design | Power Management functions |
| SUB-006-Functions | Design | External Communications functions |
