(1)RequestPlease request testing for product realization.
Our sales managers listen to customer requirements, and work with customers to consider how best to meet those requirements.(2)PlanningManagers summarize a plan for the testing equipment to be used and what needs to be prepared in advance in order to realize customer requirements.
They have customers confirm these plans before testing is conducted.(3)TestingWe conduct testing based on advance planning.
We run detailed checks to see whether the required results have been obtained, and then adjust the test conditions.

In principle, we have customers attend so that we can discuss test circumstances with them on site to ensure testing advances toward achieving goals.(4)Results meetingWe hold a meeting to take a look back to determine whether or not test results achieved the initial goals.
We use this meeting to share issues observed based on test results with customers, and to connect those issues to subsequent tests.
This is an important step in realizing requirements.(5)Report submissionWe submit reports within one week after testing is complete.
