1 Purpose

Definition of Safe Launch Procedure

2 Definitions

Launch Management

Launch Management of a serial product comprises all activities for planning, executing and

controlling of a product launch with the defined production systems. Launch management starts

with the pre production release and ends with the full ramp up and the process readiness of all

products, processes and production devices.

Safe Launch

Launch Management with risk oriented enhanced control activities.

Safe Launch Coordinator: Responsible for the implementation of the defined Safe Launch Plan.

He is in charge of rating the different Safe Launch Phases and defining the necessary corrective

actions. Based on the results he decides about end or continuation of Safe Launch according to

defined exit criteria. The development team in cooperation with the production site nominates the

Safe Launch coordinator; it can be a member of the project team or a production site employee.

3 Responsibilities

Project Team: risk assessment, definition of safe launch

Production location; supplier: execution of safe launch

4 Procedure

4.1 Definition of Safe Launch

Step 1: Risk assessment in kick off resp. design/Process Review (Definition of high impact

parts or process steps), see checklists CF-037 part 1

Decision for safe launch in review 3

Step 2: Documentation/preliminary performance assessment at initial sample or production

review

Review initial sampling data in respect to process and gage capability

see checklists CF-037 part 2

Decision for safe launch in review 4

4.2 Creation of Safe Launch Plan

see CF – 036

4.2.2 Test Intervals

- tool dependant characteristics 3 parts first/last piece at set-up, shift change and tooling

replacement/adjustment

- controllable characteristics 100% if process capability not ok; otherwise according to SPC

sampling plan

- Attributive characteristics 100%

- all customer interface characteristics 100%

- Labels and part identification as well as packaging: 100% visual check as well as check

of the material index (MR) – see dock audit form

- Tracking of process capabilities of important characteristics (except go/no go)

Note: tests have to be carried out additional to production control plan
