The article written by Akın Ateş, Suurmond, Luzzini, and Krause published in the Journal of Supply Chain Management in 2022. The study represents a comprehensive quantitative synthesis of existing empirical research on supply chain complexity and its performance implications.
The meta-analysis article examines 27,668 observations from 102 independent samples across 123 studies. It demonstrates that the relationship between complexity and firm performance is far more controversial than previously understood that complexity is universally detrimental.
The authors reveal that while supply chain complexity negatively affects operational performance, it simultaneously enhances innovation performance and can improve financial performance. This paradoxical finding suggests that complexity serves dual roles. It is both an operational burden and a strategic resource.
The study also provides crucial insights for managers navigating the trade-offs between operational efficiency and innovation capacity in today’s complex global supply chains. By distinguishing between upstream, downstream, and internal complexity, as well as between detail and dynamic complexity, the paper offers a framework for understanding how different types of complexity impact various performance dimensions.

Order from Chaos: A Meta-Analysis of Supply Chain Complexity and Firm Performance
How supply chain complexity differentially affects operational, innovation, and financial performance across upstream, internal, and downstream levels, based on 27,668 observations from 102 independent samples.
Akın Ateş et al. (2022) conducted a comprehensive meta-analysis of 123 empirical studies to disentangle the complex relationship between supply chain complexity and firm performance. While SCC is traditionally seen as detrimental, their findings reveal nuanced effects across different performance dimensions and supply chain levels.
Summary
This meta-analysis quantitatively synthesizes evidence from 27,668 observations across 102 independent samples to examine the relationship between supply chain complexity (SCC) and firm performance. The study challenges the conventional view that SCC is universally detrimental by revealing differential effects across performance dimensions.
Core Findings:
- Differential Performance Effects: SCC has a negative effect on operational performance but positive effects on innovation and financial performance.
- Level-Specific Impacts: Upstream complexity negatively affects operational performance, downstream complexity enhances innovation, and internal complexity improves financial performance.
- Detail vs. Dynamic Complexity: Dynamic complexity is more detrimental than detail complexity, particularly for operational performance.
- Cultural Moderators: Individualistic and long-term oriented cultures experience more negative effects from SCC.
Key Statistics:
- 27,668 observations from 102 independent samples
- 123 empirical studies from 39 journals
- SCC negatively correlates with operational performance (r = -0.083)
- SCC positively correlates with innovation performance (r = 0.171)
- SCC positively correlates with financial performance (r = 0.078)
Conceptual Framework
The study examines SCC through two primary dimensions: level (upstream, internal, downstream) and type (detail vs. dynamic complexity), and their impact on three performance categories.
SCC Dimensions:
| Level | Detail Complexity | Dynamic Complexity |
|---|---|---|
| Upstream | Number & heterogeneity of suppliers | Supplier lead time volatility, delivery reliability |
| Internal | Number of products/parts, product variety | Process changes, schedule instability |
| Downstream | Number & heterogeneity of customers | Demand fluctuations, customer-driven changes |
Theoretical Perspectives:
- Transaction Cost Economics (TCE): Explains negative operational effects through bounded rationality and coordination costs
- Knowledge-Based View (KBV): Explains positive innovation effects through access to diverse knowledge sources
- Contingency Theory: Recognizes that SCC effects depend on contextual factors and management approaches
Performance Measures:
- Operational Performance: Cost, quality, delivery, flexibility
- Innovation Performance: New product development, time-to-market, innovation rate
- Financial Performance: ROI, profitability, market value
Hypotheses & Results
The study tested three main hypotheses with sub-hypotheses for different SCC levels, revealing nuanced relationships.
Hypothesis 1: SCC and Operational Performance
Prediction: SCC negatively affects operational performance
Result: Supported (r = -0.083)
| Sub-Hypothesis | Result | Effect Size | Key Insight |
|---|---|---|---|
| H1a: Upstream complexity | Supported | r = -0.149 | Strongest negative effect; both detail and dynamic complexity harmful |
| H1b: Downstream complexity | Partially supported | r = -0.090 (dynamic only) | Only dynamic complexity (demand uncertainty) harms operations |
| H1c: Internal complexity | Not supported | Not significant | Firms cope better with internal than external complexity |
Hypothesis 2: SCC and Innovation Performance
Prediction: SCC positively affects innovation performance
Result: Supported (r = 0.171)
| Sub-Hypothesis | Result | Effect Size | Key Insight |
|---|---|---|---|
| H2a: Upstream complexity | Not significant | r = 0.113 | Positive but not significant; operational challenges may offset benefits |
| H2b: Downstream complexity | Supported | r = 0.187 | Strongest positive effect; diverse customers drive innovation |
| H2c: Internal complexity | Not significant | r = 0.138 | Positive but not significant; may require specific capabilities |
Hypothesis 3: SCC and Financial Performance
Prediction: SCC negatively affects financial performance
Result: Contrary to prediction – positive effect found (r = 0.078)
| Sub-Hypothesis | Result | Effect Size | Key Insight |
|---|---|---|---|
| H3a: Upstream complexity | Not significant | Positive but not significant | Coordination costs may offset financial benefits |
| H3b: Downstream complexity | Not significant | Positive but not significant | Market access benefits balanced by service costs |
| H3c: Internal complexity | Supported | r = 0.098 | Product variety drives sales growth and financial performance |
Moderating Factors
The meta-regression analysis identified several factors that moderate the SCC-performance relationship.
Construct Operationalization:
- Detail vs. Dynamic Complexity: Dynamic complexity is significantly more detrimental than detail complexity
- Performance Dimensions: Effects differ substantially across operational, innovation, and financial performance
- SCC Levels: Downstream and internal complexity have more positive effects than upstream complexity
Study Design Characteristics:
- Journal Ranking: Studies in ABS4+ journals report larger effect sizes (more negative for operational performance)
- Data Source: No significant difference between primary and secondary data
- Country/Industry Scope: No significant difference between single vs. multiple country/industry studies
Cultural Moderators (Hofstede Dimensions):
| Cultural Dimension | Effect on SCC-Performance Relationship | Interpretation |
|---|---|---|
| Individualism | More negative impact | Individualistic cultures struggle more with SCC coordination |
| Long-term Orientation | More negative impact | Difficulty coping with uncertainty over extended periods |
| Uncertainty Avoidance | Marginal negative impact | Cultures averse to uncertainty find SCC more challenging |
| Power Distance | No significant effect | Hierarchical structures neither help nor hinder SCC management |
| Masculinity | No significant effect | Competitive vs. cooperative values don’t moderate SCC effects |
Key Moderator Insights:
- Dynamic complexity requires more management attention than detail complexity
- Cultural context significantly influences how SCC affects performance
- Methodological choices (journal ranking) correlate with effect size magnitude
- The SCC-performance relationship is highly context-dependent
Theoretical & Managerial Implications
Theoretical Contributions:
- Reconceptualizing SCC: Moves beyond “SCC as cost driver” to recognize strategic benefits
- Integrating Theories: Combines TCE (negative effects) and KBV (positive effects) for comprehensive understanding
- Contingency Perspective: Emphasizes that SCC effects depend on type, level, and context
- Measurement Refinement: Highlights importance of distinguishing detail vs. dynamic complexity
Managerial Implications:
