2.1 交付周期（Lead Time）
交付周期是衡量从需求提出到功能上线全过程耗时的重要指标，反映了团队的响应速度和交付能力。
class LeadTimeCalculator:
def __init__(self, data_source):
self.data_source = data_source
def calculate_lead_time(self, start_event, end_event):

:param start_event: 起始事件（如需求创建）
:param end_event: 结束事件（如功能上线）
:return: 交付周期（天数）
"""

end_time = self.get_event_time(end_event)
if start_time and end_time:
lead_time = (end_time - start_time).days
return lead_time
else:
return None
def get_event_time(self, event):
"""

print(f"团队平均交付周期: {team_lead_time['average']} 天")2.2 吞吐率（Throughput）
吞吐率衡量团队在特定时间内完成的工作量，是评估团队产能的重要指标。
