1. Metrics
    1. Why
      1. to answer questions
      2. to make better business decisions
      3. to come conversations and insights to help teams succeed
    2. !
      1. use multiple metrics
        1. never rely on a single metric
        2. good metrics should surprise you every now and then
          1. they generate questions as well, not just answers

  2. Metrics...
    1. value
      1. What should we do?
      2. When should we do it?
      3. What should we do next?
      4. Ex
        1. How many customers have we gained this month?
        2. How much are they spending?
        3. Which features are they using the most?
        4. How long do people stay with us as customers?
        5. Do they recommend us to their friends?
    2. quality
      1. failure demand
    3. operational metrics (hygiene factors)
      1. How much do we have left to do this week/month/year?
      2. How much time do we have to finish this?
      3. How long does it take us to deliver things?
      4. Delivery rate, Cycle time
  3. Throughput
    1. What
      1. How fast are we going?
      2. the number of work items that were completed during a particular period of time
    2. Why
      1. helps you become more predictable
        1. Story points & velocity
          1. Are our estimates really working?
        2. Lead time
        3. to base on historical data and the metrics
        4. !=
          1. a high amount WIP?
          2. no focusing
          3. wastes
          4. time
          5. quality decease
          6. work
          7. product
          8. queues in process visible?
          9. unexpected events?
      2. way for Team improving
      3. important for each Team role
        1. faster meeting!
        2. realistic expectation & promises
      4. improve planning and forecast
        1. use it for short term predictions
          1. How many stories can we complete in the next sprint?
          2. How much can we get done in the next two weeks?
        2. for long term predictions
          1. How long will it take?
          2. When are we going to complete this project/functionality/group of stories?
      5. to validate experiments
        1. Current situation
        2. Our hypothesis
        3. Action
        4. Expected results
        5. How to measure our results
    3. calculate!
      1. count the number of work items that have been completed in a fixed period of time
        1. split throughput by work item type
          1. follow a different process
          2. the same process with different speed
    4. stat
      1. Average & median
      2. Standard deviation
      3. Min and max
      4. Mode
        1. the most common throughput
      5. Probability percentiles
