Low productivity - teams might be facing distractions or having tech debt, reducing their agility 

Discovered by combination of metrics:

• Velocity: Committed vs. Completed, when team does not meet commitments leaving sprint backlog in not completed state by the end of iteration 
• Scrum Cycle Time, when Max & Average Time increases without any blockers or suspended processes in delivery pipeline (Number of Open Work Stoppages)
• Throughput, when Throughput is unstable, although there aren't much changes in team setup/vacations

Recommendations: 

1. Build delivery plan - product and sprint levels
2. Enhance Sprint execution
3. Introduce or enhance EngX in delivery
