Introduction

Overview of the Standard Framework

ISO 18676:2017 provides systematic guidance for space system engineering management. Its core framework includes:

Management Dimensions	Traditional Engineering Management	Space System Engineering Management
Requirement Characteristics	Pre-defined	Continuous Iterative Evolution
Complexity Management	Single Technical Field	Cross-Material/Energy/Information Fields
Verification Methods	Full Verification	Risk-Based Sampling

---

System Engineering Management Positioning

Chapter 4 of the standard clarifies the triple positioning of system engineering management in space projects:

V model is applied in the life cycle of space systems:

1. Concept phase: Operational concept development
2. Development phase: Requirements analysis → Architecture design → Detailed design
3. Production phase: AIV (Assembly Integration Verification) → System confirmation

---

Key points for SEMP preparation

The System Engineering Management Plan (SEMP) specified in Chapter 6 should include:

Elements	NASA standards	ECSS Standards	ISO 18676 Requirements
Organizational Structure	Matrix Management	Functional Management	Hybrid Model
Technical Review	7 Types of Mandatory Review	5-Stage Review	9 Types of Core Review

---

Implementation Recommendations

Application of Leading Indicators (LI)

The leading indicators recommended in Chapter 5.3 should include:

• Requirement Stability Index: Ratio of TBD/TBR Requirements
• Interface Maturity: Frequency of ICD Changes
• Verification coverage: demand verification closed-loop rate

WBS development principles

The work breakdown structure emphasized in Chapter 8 should follow:

1. Product-oriented layering (system → subsystem → component)
2. 100% rule (covering all deliverables)
3. Aligned with PBS (Product Breakdown Structure)
