I. Function Introduction

Selection items are standardized inspection units for multi-choice scenarios, supporting:

• Multi-selection: Select one or more results from preset options
• Risk Assessment: Configure risk scores for different options
• Classification Management: Support hierarchical option organization
• Data Statistics: Support option distribution analysis

Core Value:

• Standardize multi-choice inspection processes
• Quantify option risk levels
• Improve data consistency
• Support complex scenario evaluation

Access Entry:

1. Administrator logs into management backend
2. Navigation menu select: 【Inspection Standards】→【Selection Items】
   

II. Add Selection Items

1. Single Addition

Operation Steps:

1. Click "New" button on toolbar

2. Fill in basic information:
   • Item Name (Required, e.g. "Equipment Failure Type")
   • Multiple Selection (Single/Multiple choice)
   • Risk Factor (Associated risk type)
   • Category Name (Classification management)
3. Add options:
   • Click "New" button on right
   • Fill in:
     • Option name (e.g. "Mechanical Failure")
     • Risk score (1-10 points)
     • Default selection
   • Can add multiple options
4. Click "Save" to complete creation

2. Batch Import

Operation Steps:

1. Click "Import" button on toolbar

2. Download Excel template

3. Fill according to specifications:
   • Item Information:
     • Item name
     • Multiple selection (Yes/No)
     • Risk factor code
   • Option Information:
     • Option name
     • Risk score
     • Default selection (Yes/No)
4. Upload file and verify
5. Process import results

Template Specifications:

Column Name	Requirement	Example	Separator
Item Name	Unique, non-repeatable	Safety Protection Missing Type
Multiple Selection	Yes/No	Yes
Risk Factor	Existing code	SAFE_002
Option Group	Option name + parameters	Protective Cover Missing,Unqualified,Qualified,0,No; Safety Lock Failure,Unqualified,Qualified,0,No	Semicolon ";" separates options Comma "," separates parameters

III. Modify Selection Items

Operation Steps:

1. Locate target selection item
2. Click "Edit" button in operation column
3. Modify:
   • Basic information (Name/Multiple selection setting)
   • Option content (Add/Delete/Modify options)
   • Risk assessment (Factor/Score)
4. Click "Save" to submit

Precautions:

• Associated inspection forms need synchronization after modification
• Original versions retained in historical records
• Core selection items require approval for modification

IV. Delete Selection Items

Operation Steps:

1. Locate target selection item
2. Click "Delete" button in operation column
3. Confirm deletion operation

Restrictions:

• Cannot delete if referenced in inspection standards
• Cannot delete if historical records exist

V. Best Practices

1. Design Principles

• Naming Conventions:
  • Item name ≤10 characters
  • Option name ≤6 characters
  • Avoid ambiguous expressions
• Option Settings:
  • Single choice: ≤5 options
  • Multiple choice: ≤10 options
  • Set "Other" as default option
• Risk Assessment:
  • Low risk: 1-3 points
  • Medium risk: 4-6 points
  • High risk: 7-10 points

2. Application Scenarios

Scenario Type	Selection Item Example	Option Settings	Multiple Selection
Fault Diagnosis	Equipment Failure Type	Mechanical/Electrical/Control System/Sensor	Yes
Defect Classification	Safety Protection Missing	Protective Cover/Emergency Stop Button/Safety Door Lock	Yes
Compliance Check	Regulatory Compliance	Fully Compliant/Partially Compliant/Non-compliant	No
Risk Assessment	Hazard Level Determination	Low/Medium/High/Extremely High	No

VI. Precautions

1. Design Standards

• Option Mutually Exclusive: Single-choice options must be mutually exclusive
• Default Settings: Must set default option
• Score Reasonableness: Match risk level
• Hierarchy Control: Option hierarchy ≤2 levels

2. Data Security

• Modification records permanently audited
• Associated changes automatically notified

3. Performance Optimization

• ≤15 selection items per inspection form
• Total options ≤50
• Avoid deep nesting
