INTRODUCTION
You have to "redesign" or create a product or system that meets the user's needs. To do this, you have identified and characterized all the service functions and found the corresponding technical functions.
After researching solutions, you'll find all the components and technological solutions to realize the technical functions.
Each component has a market value and represents a cost. With a simple correspondence table, you can calculate the cost of performing a function.
This sheet explains how to do it.
