1. The acceptance test for the whole system is executed as an experience-based test.
2. The control algorithms on the server are checked against standard of the energy saving regulation.
3. The functional test of the thermostat is performed as risk-based testing.
4. The security tests of data / communication via the internet are executed together with external security experts.

18. You will be invited to a review. The work product to be reviewed is a description of the in-house document creation process. The aim of the description is to present the work distribution between the different roles involved in the process in a way that can be clearly understood by everyone.

You will be invited to a checklist-based review. The checklist will also be sent to you. It includes the following points:

i. Is the person who performs the activity clearly identified for each activity?
ii. Are the entry criteria clearly defined for each activity?
iii. Are the exit criteria clearly defined for each activity?
iv. Are the supporting roles and their scope of work clearly defined for each activity?
