Acceptance Criteria

• Acceptance Criteria
  1. Online/On-site acceptance is available.
  2. Acceptance criteria: Huawei must submit standard deliverables for each service sub-item. The customer can confirm acceptance on the Huawei Cloud console or by signing and sealing the GaussDB(DWS) Consulting and Governance Service Acceptance Report offline.
• Service acceptance notes
  • Acceptance of deliverables should focus on substantive content. Minor discrepancies in format, vocabulary, and embellishment should not prevent acceptance, though Huawei shall address these within a reasonable timeframe.
  • Throughout the project, deliverables must be discussed and reviewed daily to ensure mutual understanding and to expedite acceptance. The customer should provide timely feedback and approval for any suggestions or requirements from Huawei. Depending on project specifics, some or all deliverables must be reviewed by the project team, business department, and reported to leadership before signing. The customer is responsible for managing and completing all internal reviews and reports before the contract-specified acceptance time.
  • Huawei shall complete deliverable modifications within 5 working days based on feedback, then submit the final version for customer acceptance.
  • After receiving the final version, the customer has 5 working days to provide feedback. Huawei should submit modified deliverables within 5 working days of receiving feedback. This process should not exceed 2 rounds (i.e., a maximum of 3 submissions). Deliverable acceptance should be completed within 15 working days from the customer receiving the final version. The customer should accept and sign the project deliverables within this period. If no written feedback is received from the customer within 5 working days of submission, the deliverables are deemed accepted as final.
  • If more time is needed due to factors other than Huawei, the project team will apply for a change request to extend the timeline and obtain corresponding payment.
  • If acceptance is not completed after 3 submission rounds within 15 working days, both parties should evaluate the impact on subsequent work and negotiate further modifications and acceptance.
  • After the deliverables are accepted and signed, any additions or deletions to the deliverables will be evaluated for complexity and risk (impact on fees, schedule, and resources), with changes executed upon agreement by both parties.
  • Once milestone deliverables are accepted, the person in charge will authorize the signing of the milestone acceptance report. Completion of tasks outside Huawei's scope should not affect milestone acceptance.
