1. High-Conflict Stages
1.1 Requirements Analysis and Communication Stage
Typical situations:
- Developers do not agree with the solutions proposed by product managers, causing disputes
- Developers believe the requirements documents provided by product managers are not clear enough, affecting subsequent development work
Core problems:
- Product managers only describe requirements verbally, lacking clear flowcharts or documents
- Unclear requirements lead to inconsistent understanding among developers, planting hidden misunderstandings
1.2 Development Implementation and Mid-term Change Stage
Common situations:
| Problem Type | Specific Manifestations |
|---|---|
| Requirement changes | Product managers temporarily change or add features, causing code rework |
| Technical communication | Product managers lack technical knowledge, low communication efficiency |
| Document absence | Changes are only communicated verbally in chat, formal documents not updated in time |
If changes are only communicated verbally in chat without timely updating formal documents, when deviations occur later, both parties easily blame each other for requirements that were “said but not written.”
1.3 Project Progress and Iteration Planning Stage
Conflict focus:
- Product managers: Face launch pressure, want to release more features as soon as possible
- Developers: Better understand the workload and difficulties of technical implementation
China-US differences:
| Aspect | Chinese Companies | US Companies |
|---|---|---|
| Overtime culture | Prevalent, constant pressure before deadlines | Emphasize work-life balance |
| Handling method | Require rushing work | Adjust scope to meet time requirements |
| Engineer attitude | Silently endure or express discontent | Directly oppose or request scope reduction |
1.4 Testing Acceptance and Release Stage
Conflict manifestations:
- Delivered features do not meet product manager expectations
- When many defects appear, both parties blame each other
Conflicts in the testing stage essentially stem from problem accumulation in previous stages, but emotions are more likely to intensify due to time pressure near release dates.
2. Main Problem Points of Conflicts
2.1 Communication Barriers and Cognitive Biases
Core problems:
- Developers tend to use technical language, focus on implementation details
- Product managers are accustomed to using business language, user perspective to express requirements
- Both parties have different focuses, may talk past each other even when discussing the same issue
2.2 Unclear Role Boundaries and Mutual Shifting of Responsibility
Typical scenarios:
- When requirement documents or process standards are imperfect, problems easily lead to mutual blame
- Testing finds features don’t meet expectations, role definitions in documents are unclear
- When projects are delayed, product blames development for low efficiency, development blames project management for poor handling
2.3 KPI and Evaluation Conflicts
Nature of conflict:
| Role | Focus Metrics |
|---|---|
| Product manager | Number of new features, commercial metrics, quickly stacking highlights |
| Technical team | System stability, on-time delivery, technical risks |
Under KPI pressure, technical managers only want tasks that are easy to implement and have controllable risks; product managers want to add features and create highlights.
2.4 Goal Inconsistency and Priority Perception Differences
| Focus | Product Manager | Developer |
|---|---|---|
| Emphasis | Market performance, user needs satisfaction | Technical feasibility, efficiency, and security |
| Priority | Quickly develop features that can capture business opportunities | First solve technical debt or performance bottlenecks |
2.5 Technical Feasibility Assessment Biases
Common phenomena:
Product managers are often not from technical backgrounds, easily underestimate the development difficulty of certain features, thinking “it looks very simple” changes make programmers exclaim “OMG need to change countless lines of code.”
Two-way problems:
- Product managers: Don’t understand technology, make unreasonable demands
- Developers: May overestimate implementation difficulty to protect schedules
2.6 Other Common Friction Points
- Temporary requirements: New requirements thrown out when development is almost finished
- Detail neglect: Developers too obsessed with technical details, neglect user experience
- Outsourcing conflicts: Conflicts between甲方 (client) and 乙方 (development team) due to contract scope and change fees
3. Summary
Key Findings
- Communication is the core amplifier: Poor communication is often an amplifier for all other problems
- Information asymmetry: Leads to understanding differences, triggers chain reactions like goal inconsistency and priority conflicts
- Stage correlation: Conflicts are often connected, misunderstandings planted in the requirements stage explode during development and testing
Solution Directions
- Process standardization
- Communication mechanism optimization
- Goal alignment
