The principle of Parameter Change is usually applied in one of four ways:
1. Change an object’s physical state to a gas, liquid, or solid.
a. i.e. Freeze the liquid centers of candies and then dip the centers in melted chocolate, rather than handling the messy, gooey, hot liquid.
2. Change the concentration or consistency.
a. i.e. Liquid soup is more concentrated than bar soap, makes it easier to dispense in the correct amount, and is more sanity when shared by more than one person.
3. Change the degree of flexibility
a. i.e. Vulcanize rubber to change its flexibility and durability
4. Change the temperature
a. i.e. Lower the temperature of medical specimens to preserve them for later analysis
Melts in your Mouth, Not in Your Hands
Once again, the medical community provides a great example of the application of this lens. Medical plaster, used to make casts, begins with a soft material. The soft material can be wrapped around the affected area, and when it cures, the plaster turns hard.
M&Ms also utilize this principle. M&M’s “melt in your mouth, not in your hands.” The parameter change was to put a candied coating around the chocolate so the candies don’t melt until you put them in your mouth.
Parameter change also refers to flexibility. With gas prices at all-time highs and continuing to rise, many people are finding ways to work from home. Working from home is an example of a parameter change in your job.
Temperature change is also a variation in parameter. For example, you raise the temperature of food in the cooking process. Cooking at a higher temperature changes the taste, aroma, textures, and chemical properties of the food.
How can you change the parameters of your product or service to improve the physical state, concentration, consistency, or flexibility of your product?
