Volere Requirements Specification Template

“The product shall download the new status parameters within 5 minutes of
a change”
Fit Criterion
Unit of measurement
Required range of values
Considerations
There is a wide variation in the importance of different types of speed
requirements. If you are working on a missile guidance system then speed is
extremely important. On the other hand, an inventory control report that is
run once every 6 months has very little need for split second speed.
Customise this section of the template to give examples of the speed
requirements that are important within your environment.
12b. Safety critical requirements
Content
Quantification of perceived risk of possible damage to people, property and
environment.

Considerations
The sample requirements given above apply to some, but not all, products. It
is not possible to give examples of every variation of safety critical
requirement. To make the template work in your environment, you should
customize it by adding examples that are specific to your products.
