The **Experiment Log** has a bit more structure than the [Storyboard](Storyboard.md). It consists of a header that describes the current Obstacle being targeted by the Experiments, and a table with six columns: Obstacle: *Describe the obstacle here.* | Date | Plan | Predict | Test | Data | Evaluate | | ---- | ---- | ------- | ---- | ---- | -------- | | Note the start date of the experiment. | Answer: What will you do next? | Answer: What do you expect? (Facts, new state) | DO (Unused column, a reminder to run the experiment.) | Answer: What actually happened? (Facts, state) | Answer: What did you learn? | You fill in a new row in this table for each Experiment you run, by answering the questions you see above in written, and keeping the following in mind: 1. The date when you (will) start the Experiment. 2. The [Experiment](Planning%20the%20next%20Experiment.md) **plan** (description, steps, approach); This should describe one of the three possible experiments: either a Go & See, Exploratory, or a Hypothesis Test experiment. 3. Your **prediction** of the expected outcome from the Experiment - which is *only* allowed to describe expected facts, state, and data. If creating the prediction is mentally easy or it is describing the obvious, it most likely isn't a proper prediction. 4. An unused column that reminds you now is the point to actually **do** the Experiment. You don't write anything in this column. 5. A column to describe the actual outcome of the Experiment - as with the predict column, *only* actual facts, state, and **data** are allowed to be documented here. 6. The last column describes the learnings from this experiment, including conjectures and insights. Here, you **evaluate** the difference between your *predictions* and the *data* you got. If applicable, it should be clear from this column why new [Obstacles](Obstacles.md) were added to the Parking Lot, and entries in the evaluation cell should create a coherent story that explains the reasoning and background behind the next experiment(s) in the log. Also, if the experiment took longer than expected, you should document here why that delay happened, and suggest possible ways of preventing that delay in the future. Hearsay, assumptions, and conjectures have no place on the Storyboard, except possibly in the first and last columns of the Experiment Log. [Experiments](Planning%20the%20next%20Experiment.md) should typically be short, something you can undertake in a few minutes, hours at worst.
