Systematic Inventive Thinking

Systematic Inventive Thinking, or SIT for short, is a modified version of TRIZ with the aims of being easier to learn, more realistic and generally more universal in application. It is almost the same as TRIZ, except for some core principles that are exclusive to SIT.

The Five Thinking Tools
One of the core changes of SIT is that the Five Thinking Tools and TRIZ's Function-Follows-Form procedure are used to generate "virtual products"; essentially undeveloped potential ideas and concepts. Without the restraint of assumptions and norms, these ideas can be wilder and more implausible but can spark new ideas that could be probable.
 * Subtraction; removal, elimination of a component to create an abstract arrangement of the remaining components
 * Multiplication; adding more copies of a component and/or tweaking the new additions to fit the parameter
 * Division; dismantling the product or a component and rearranging to form a new product, the more pieces it is divided into, the more freedom and leeway for experimenting with new ideas
 * Task Unification; the assigning of a new and additional task to an existing product or component, forcing the consideration of different specifications of the product or component but also increasing efficiency
 * Attribute Dependency; Creating and destroying dependencies between components, the product, the customer and/or customisable variables of the product.
