1. 引言
现代软件开发项目往往涉及多个专业领域，需要不同角色的专家协同工作。在传统的开发团队中，这通常由人类开发者、设计师、测试工程师等角色共同完成。BMAD-METHOD框架通过多个专业化的AI代理，模拟了这种多角色协作模式，并通过一套完整的协作机制确保各代理能够高效协同工作。
BMAD-METHOD团队协作机制的核心特点包括：
- 角色专业化：每个代理都有明确的专业领域和职责
- 流程标准化：通过标准化的工作流程协调各代理的工作
- 信息共享机制：通过文档和标准化格式实现信息传递
- 状态同步机制：通过状态管理确保各代理对项目状态的理解一致
- 质量保障机制：通过检查清单和质量门确保协作质量
2. 团队协作架构设计
BMAD-METHOD的团队协作架构采用分层设计，由代理层、协作层和管理层三个核心层组成。
2.1 代理层
代理层包含所有专业化的AI代理，每个代理都有其特定的职责和能力：
# BMAD-METHOD代理团队结构
agent-team:
planning-phase:
- analyst # 分析师代理
- pm # 产品经理代理
- architect # 架构师代理
- ux-expert # UX专家代理（可选）
development-phase:
- sm # Scrum主管代理
- dev # 开发者代理
- qa # QA代理
coordination:
- po # 产品负责人代理
- bmad-master # 主控代理
2.2 协作层
协作层负责代理之间的信息传递和工作协调：
class AgentCollaborationLayer:
def __init__(self):
self.message_bus = MessageBus()
self.document_repository = DocumentRepository()
self.state_manager = StateManager()
def coordinate_agents(self, agents, workflow):
"""
协调多个代理的工作
"""
# 1. 初始化工作流
current_step = workflow.get_starting_step()
# 2. 按步骤执行工作流
while not workflow.is_complete(current_step):
# 3. 确定当前步骤涉及的代理
involved_agents = workflow.get_agents_for_step(current_step)
# 4. 分配任务给代理
tasks = workflow.get_tasks_for_step(current_step)
results = self.assign_tasks_to_agents(involved_agents, tasks)
# 5. 收集和整合结果
integrated_result = self.integrate_results(results)
# 6. 更新共享文档
self.update_shared_documents(integrated_result)
# 7. 更新项目状态
self.state_manager.update_state(current_step, integrated_result)
# 8. 移动到下一步
current_step = workflow.get_next_step(current_step)
return self.state_manager.get_final_state()
def assign_tasks_to_agents(self, agents, tasks):
"""
将任务分配给代理
"""
results = {}
for agent in agents:
agent_tasks = self.filter_tasks_for_agent(tasks, agent)
result = agent.execute_tasks(agent_tasks)
results[agent.id] = result
return results
2.3 管理层
管理层负责整个团队的协调和监控：
class TeamManagementLayer:
def __init__(self):
self.collaboration_layer = AgentCollaborationLayer()
self.performance_monitor = PerformanceMonitor()
self.quality_assurance = QualityAssurance()
def manage_team_workflow(self, team, project):
"""
管理团队工作流
"""
# 1. 初始化项目
self.initialize_project(project)
# 2. 激活代理团队
active_agents = self.activate_agent_team(team, project)
# 3. 执行规划阶段工作流
planning_results = self.execute_planning_workflow(active_agents, project)
# 4. 执行开发阶段工作流
development_results = self.execute_development_workflow(active_agents, project)
# 5. 监控团队性能
performance_metrics = self.monitor_team_performance(active_agents)
# 6. 确保质量标准
quality_report = self.ensure_quality_standards(project)
# 7. 生成总结报告
final_report = self.generate_final_report(
planning_results,
development_results,
performance_metrics,
quality_report
)
return final_report
3. 核心协作模式
BMAD-METHOD框架支持多种协作模式，以适应不同的开发场景和需求。
3.1 顺序协作模式
在顺序协作模式中，代理按照预定义的顺序依次执行任务，前一个代理的输出作为后一个代理的输入：
# 顺序协作模式示例
class SequentialCollaboration:
def __init__(self):
self.workflow_steps = [
"analyst_research",
"pm_create_prd",
"architect_design",
"sm_create_story",
"dev_implement",
"qa_review"
]
def execute_sequential_workflow(self, project):
"""
执行顺序工作流
"""
context = {"project": project}
for step in self.workflow_steps:
# 根据步骤确定需要的代理
agent = self.get_agent_for_step(step)
# 执行步骤
result = agent.execute_step(step, context)
# 更新上下文
context[step] = result
# 保存中间结果
self.save_intermediate_result(step, result)
return context
def get_agent_for_step(self, step):
"""
根据步骤获取对应的代理
"""
agent_mapping = {
"analyst_research": AnalystAgent(),
"pm_create_prd": PMAgent(),
"architect_design": ArchitectAgent(),
"sm_create_story": SMAgent(),
"dev_implement": DevAgent(),
"qa_review": QAAgent()
}
return agent_mapping.get(step)
3.2 并行协作模式
在并行协作模式中，多个代理可以同时执行不同的任务，提高整体效率：
# 并行协作模式示例
class ParallelCollaboration:
def __init__(self):
self.concurrent_tasks = {
"market_research": AnalystAgent(),
"technical_research": ArchitectAgent(),
"user_research": UXExpertAgent()
}
def execute_parallel_workflow(self, project):
"""
执行并行工作流
"""
import concurrent.futures
results = {}
# 使用线程池并行执行任务
with concurrent.futures.ThreadPoolExecutor(max_workers=3) as executor:
# 提交任务
future_to_task = {
executor.submit(agent.execute_task, task_name, project): task_name
for task_name, agent in self.concurrent_tasks.items()
}
# 收集结果
for future in concurrent.futures.as_completed(future_to_task):
task_name = future_to_task[future]
try:
result = future.result()
results[task_name] = result
except Exception as exc:
results[task_name] = f"任务执行出错: {exc}"
return results
3.3 混合协作模式
混合协作模式结合了顺序和并行的特点，在不同阶段采用不同的协作方式：
# 混合协作模式示例
class HybridCollaboration:
def __init__(self):
self.phases = {
"planning": {
"type": "sequential",
"steps": ["analyst_research", "pm_create_prd", "architect_design"]
},
"development_preparation": {
"type": "parallel",
"tasks": ["sm_shard_epics", "sm_shard_architecture", "dev_setup_environment"]
},
"development_cycle": {
"type": "sequential",
"steps": ["sm_create_story", "dev_implement", "qa_review"]
}
}
def execute_hybrid_workflow(self, project):
"""
执行混合工作流
"""
overall_results = {}
for phase_name, phase_config in self.phases.items():
if phase_config["type"] == "sequential":
results = self.execute_sequential_phase(phase_config["steps"], project)
elif phase_config["type"] == "parallel":
results = self.execute_parallel_phase(phase_config["tasks"], project)
overall_results[phase_name] = results
return overall_results
def execute_sequential_phase(self, steps, project):
"""
执行顺序阶段
"""
sequential_collab = SequentialCollaboration()
return sequential_collab.execute_sequential_workflow(project)
def execute_parallel_phase(self, tasks, project):
"""
执行并行阶段
"""
parallel_collab = ParallelCollaboration()
return parallel_collab.execute_parallel_workflow(project)
4. 信息共享机制
在多代理协作中，信息的有效共享是确保协作成功的关键。
4.1 文档共享机制
BMAD-METHOD通过标准化的文档格式实现信息共享：
# 文档共享机制示例
class DocumentSharingMechanism:
def __init__(self):
self.document_templates = {
"project_brief": "project-brief-tmpl.yaml",
"prd": "prd-tmpl.yaml",
"architecture": "architecture-tmpl.yaml",
"user_story": "story-tmpl.yaml"
}
def share_information_through_documents(self, source_agent, target_agent, info_type):
"""
通过文档共享信息
"""
# 1. 源代理创建文档
template = self.document_templates[info_type]
document = source_agent.create_document(template)
# 2. 保存文档到共享存储
document_path = self.save_to_shared_storage(document, info_type)
# 3. 通知目标代理
self.notify_agent(target_agent, "new_document_available", {
"document_path": document_path,
"document_type": info_type,
"source_agent": source_agent.id
})
return document_path
def save_to_shared_storage(self, document, doc_type):
"""
保存文档到共享存储
"""
import os
import datetime
# 创建文档路径
timestamp = datetime.datetime.now().strftime("%Y%m%d_%H%M%S")
filename = f"{doc_type}_{timestamp}.md"
docs_dir = "shared_documents"
if not os.path.exists(docs_dir):
os.makedirs(docs_dir)
document_path = os.path.join(docs_dir, filename)
# 保存文档
with open(document_path, 'w', encoding='utf-8') as f:
f.write(document)
return document_path
4.2 状态同步机制
通过状态管理确保各代理对项目状态的理解一致：
# 状态同步机制示例
class StateSynchronization:
def __init__(self):
self.shared_state = {}
self.state_observers = []
def update_shared_state(self, key, value, updater_agent):
"""
更新共享状态
"""
# 更新状态
self.shared_state[key] = value
# 记录更新历史
if "history" not in self.shared_state:
self.shared_state["history"] = []
self.shared_state["history"].append({
"key": key,
"value": value,
"updated_by": updater_agent,
"timestamp": self.get_current_timestamp()
})
# 通知观察者
self.notify_observers(key, value, updater_agent)
def register_state_observer(self, observer):
"""
注册状态观察者
"""
self.state_observers.append(observer)
def notify_observers(self, key, value, updater_agent):
"""
通知观察者状态更新
"""
for observer in self.state_observers:
observer.on_state_change(key, value, updater_agent)
def get_shared_state(self, key=None):
"""
获取共享状态
"""
if key:
return self.shared_state.get(key)
else:
return self.shared_state.copy()
4.3 消息传递机制
通过消息传递实现代理间的实时通信：
# 消息传递机制示例
class MessagePassingMechanism:
def __init__(self):
self.message_queues = {}
self.message_handlers = {}
def send_message(self, sender, recipient, message_type, content):
"""
发送消息
"""
message = {
"sender": sender,
"recipient": recipient,
"type": message_type,
"content": content,
"timestamp": self.get_current_timestamp(),
"status": "pending"
}
# 将消息添加到接收者的队列
if recipient not in self.message_queues:
self.message_queues[recipient] = []
self.message_queues[recipient].append(message)
# 触发消息处理
self.process_pending_messages(recipient)
def register_message_handler(self, agent_id, message_type, handler):
"""
注册消息处理器
"""
if agent_id not in self.message_handlers:
self.message_handlers[agent_id] = {}
self.message_handlers[agent_id][message_type] = handler
def process_pending_messages(self, agent_id):
"""
处理待处理消息
"""
if agent_id not in self.message_queues:
return
pending_messages = self.message_queues[agent_id]
for message in pending_messages:
if message["status"] == "pending":
self.handle_message(message)
def handle_message(self, message):
"""
处理消息
"""
recipient = message["recipient"]
message_type = message["type"]
if (recipient in self.message_handlers and
message_type in self.message_handlers[recipient]):
handler = self.message_handlers[recipient][message_type]
response = handler(message["content"])
message["status"] = "processed"
message["response"] = response
# 如果需要回复，发送回复消息
if response and "reply_to" in message:
self.send_message(
recipient,
message["sender"],
"reply",
response
)

"""
# 1. 分析师进行市场研究
research_result = self.agents["analyst"].conduct_research(project_idea)
# 2. 创建项目简报
brief = self.agents["analyst"].create_project_brief(research_result)
# 3. 产品经理基于简报创建PRD
prd = self.agents["pm"].create_prd(brief)
# 4. 架构师基于PRD设计架构
architecture = self.agents["architect"].design_architecture(prd)
# 5. 协调和验证文档一致性
alignment_check = self.verify_document_alignment(prd, architecture)
return {
"research": research_result,
"brief": brief,
"prd": prd,
"architecture": architecture,
"alignment": alignment_check
}
def verify_document_alignment(self, prd, architecture):
"""

"""
# 检查PRD中的功能需求是否在架构中有对应设计
prd_features = self.extract_features_from_prd(prd)
arch_components = self.extract_components_from_architecture(architecture)
alignment_issues = []
for feature in prd_features:
if not self.find_corresponding_component(feature, arch_components):
alignment_issues.append({
"issue": f"PRD中的功能'{feature}'在架构中没有对应设计",
"suggestion": "请架构师补充相关设计"
})
return {

# 2. 开发者实现故事
implementation_result = self.agents["dev"].implement_story(refined_story)
# 3. QA代理审查实现
review_result = self.agents["qa"].review_implementation(implementation_result)
# 4. 根据审查结果决定下一步
if review_result["gate"] == "PASS":
final_status = "Done"
elif review_result["gate"] == "CONCERNS":
# 需要开发者处理关注点
implementation_result = self.agents["dev"].address_concerns(
implementation_result,
