You are asked to write a PostgreSQL query to analyze service delivery performance by team from Deloitte operational reporting data. Return one row per team per week for completed service requests, showing total requests, on-time completions, average resolution hours, and a KPI status that labels each team-week as On Track, At Risk, or Needs Attention based on on-time rate and average resolution time.
Use the request creation week for grouping, include only requests created in January 2024, and exclude cancelled requests from the KPI calculations. The result should be sorted by week and team name.
