<spiffworkflow:instructionsForEndUser>Thanks for checking out our introduction to Decision Tables - this example was very simple, but you will find it is an excellent way to represent complex business rules in a way that is easy to think about and maintain. Change your prices in once place - and then re-use that decision table everywhere you need it. Future articles can show you how to expose this logic as an API endpoint - so your business experts can define their decision tables, and all the rest of your software can ask what the prices are today -- imagine if your sales team had that kind of immediate control - and could stipulate A/B price splits independently of your E-Commerce team.

### Order Details
|
|
|
|
The base price for your {{size}} Pizza is ${{base_price}}.
|
|
|
|
Additional toppings for a {{size}} Pizza cost ${{cost_per_topping}}.
|
|
|
|
The total cost of your pizza is ${{total cost}}.
|
|
|
|
Thank you for your order!
|
|
|
|
#### Calcuations
|
|
We used a decision table to come up with the total costs. Decision tables, in the simplest form are a series of conditions stated like **IF** this is true **THEN** this is the result. You can open the file up by going to the Model and clicking on the pizza_prizes.dmn table. But here is a sample of what it conatins:
|
|
|
|
|
|
| when **Size** | then **base_price** | and **cost_per_topping** |
|
|
| ----- | ----- | ----- |
|
|
| "Personal" | 10.00 | 1.00 |
|
|
| "Medium" | 14.00 | 1.50 |
|
|
| "Large" | 16.00 | 2.00 |
|
|
|
|
Decision tables are a great way to define a set of business requirements clearly and consistently, and in a way that is super easy to maintain over time. </spiffworkflow:instructionsForEndUser>
