The three fundamental questions of the model for improvement:
1. Aim (How much? and By when?): I will consume at least 1 serving of fruits/vegetables with every meal eaten by the next month
2. Measures (How will we know a change is an improvement?):
- Outcome measures (How is the system performing?): Percentage = number of times successfully consuming AT LEAST 1 serving of fruits OR vegetables per meal eaten/total meals eaten. Data will be collected manually when eating real food only (not counting desserts/snacks). Baseline measurements will be excluded for convenience.
- Process measures (Are parts in the system performing reliably as planned?): The number of days with at least 2 servings of fruits/vegetables in house, the percentage of successfully getting a salad when eating food without roughage.
- Balancing measures (Did the changes we made to improve one part of the system mess up other parts?): One month after successfully eating at least 1 serving of fruits/vegetables per meal, I should not gain more than 10% of my baseline weight as a result of trying to eat more roughage. This data will be collected before and after 30 consecutive days of achieving the outcome measure. I don't have a scale so we'll have to skip this one.
3. Changes (What changes can we make that will result in improvement?):
- Keep at least 2 servings of fruits/vegetables in house at all times
- If there is no roughage accompanying the food I order when eating out, I must get a serving of salad with my food.
- Objective: increase roughage consumption
- Question/prediction: Will keeping roughage in house and ordering salads when eating out increase roughage consumption?
- Plan: For the next week I will keep at least 2 servings of fruits/vegetables in house at all times, and if there is no roughage accompanying the food I order when eating out, I must get a serving of salad with my food.
- Problems: Cherry tomatoes go bad quickly and I can't shop that often, must find longer-lasting roughage!
- Unexpected observation:
- Plan for next cycle: keep a bag of salad vegetables and Japanese salad dressing in house at all times? (yum!)
