CHAPTER 01
Positioning and roles
Understand the mechanism and accountabilities before planning work.
Positioning and roles
TISAX is an assessment-results exchange mechanism for the automotive industry, not a conventional management-system certificate.
- ENX governs participation and exchange
- An accredited audit provider performs the formal assessment
- Consultants may support readiness but do not decide labels or results
CHAPTER 02
Registration, assessment and exchange
See the complete journey as connected stages.
Registration, assessment and exchange
The participant registers its scope, selects an audit provider, completes the assessment and controls result sharing through the ENX portal.
- Readiness support is separate from formal assessment
- Sharing permissions should follow the business relationship
- Portal status should be verified by the participant
CHAPTER 03
Preparing for registration
Prepare legal, contact and requirement information before entering the portal.
Preparing for registration
Collect the legal entity name, addresses, contacts, billing data, customer requirement and intended timing, and agree internal ownership before registration.
- Include legal, procurement, security and business owners
- Confirm who may accept terms and scope decisions
CHAPTER 04
Scope and site planning
Scope decisions shape quotation, remediation and evidence.
Scope and site planning
Start from the customer requirement and information flow, then identify the organisational units, systems, people and physical areas that support the relevant business.
- Separate shared evidence from site evidence
- Record local differences and owners
- Avoid duplicate site definitions
CHAPTER 05
Objectives and protection needs
Base objectives on customer demand and the real business context.
Objectives and protection needs
Confirm the exact terminology, required objectives, expected scope and intended recipients with the customer before choosing protection needs.
- Too little may not satisfy the customer
- Unjustified over-scoping adds complexity
CHAPTER 06
Choosing an audit provider
Keep consulting and formal assessment roles separate.
Choosing an audit provider
Compare scope, assessment method, language, automotive experience, site logistics, timing and communication—not price alone.
- The assessment contract is between the participant and audit provider
- Formal conclusions remain independent
CHAPTER 07
VDA ISA self-assessment and readiness
Test whether controls operate and evidence is credible.
VDA ISA self-assessment and readiness
Review governance, technical controls, physical conditions and operating evidence together, then prioritise remediation by risk, dependency and lead time.
- Policies alone are insufficient
- Long-lead site and system changes should start early
CHAPTER 08
Assessment and evidence communication
Align interviews, sites, systems and records.
Assessment and evidence communication
Policies, responsibilities, operating records, system configuration and improvement evidence should tell a consistent and traceable story.
- Prepare accountable owners
- Use mock assessment to find contradictions and missing evidence
CHAPTER 09
Remediation and follow-up
Close findings through accountable and verifiable action.
Remediation and follow-up
For every issue, document the cause, action, owner, deadline and evidence that the corrective action operates effectively.
- Maintain one issue register
- Escalate high-risk, cross-functional and long-lead items
CHAPTER 10
Results, labels and sharing
Manage exchange through the ENX portal, not a public certificate database.
Results, labels and sharing
Assessment results and labels are managed within the exchange mechanism and shared according to participant-controlled permissions and business needs.
- Verify the intended recipient
- Do not describe labels as certificates
- Avoid publishing sensitive assessment detail
CHAPTER 11
Label renewal and reassessment
Start early and reassess change, scope and evidence.
Label renewal and reassessment
Where continuous label validity is required, use the current ENX guidance to plan early and review organisational, system, site and customer changes.
- Keep evidence operating between assessment cycles
- Coordinate internal remediation with external availability
CHAPTER 12
Official sources and boundaries
Use current official sources and record version checks.
Official sources and boundaries
Obtain the handbook, participation terms, fees, audit-provider list and appendices from ENX official channels; the English leading version prevails where versions differ.
- This guide is an independent practical interpretation
- Record the source version and review date
