Statement of Work (SOW)

Service Overview

As data continuously grows and becomes more important, more and more enterprises need to build or reconstruct data warehouse platforms. To save money and protect data, many businesses choose to build their data warehouses on the cloud. Data warehouses typically store a large amount of data, often measured in terabytes or petabytes, and involve complex relationships between databases and tables. Moving data warehouses to the cloud presents many challenges, such as managing multiple platforms, components, and vendors. Traditional companies often lack the expertise and experience required for data warehouse transformation and cloud migration. Consequently, migrating data warehouses, upgrading architectures, and transferring data to the cloud can be difficult for them. Huawei Cloud GaussDB(DWS) provides a professional team and comprehensive migration tools to help customers smoothly, efficiently, and securely migrate their data warehouses.

Acceptance Criteria

  • Acceptance Criteria
    1. Online and on-site acceptance are 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) Cloud Migration and Implementation Service Acceptance Report offline.
  • Service Acceptance Criteria
    • The acceptance should focus on the content of the delivered documents. If the content of the deliverables complies with this SOW, the deliverables should pass the acceptance. A few formatting or description issues should not be used as the reason for rejecting the deliverables. However, Huawei should modify the issues within a reasonable period of time as required by customers.
    • To ensure mutual understanding and expedite acceptance, it is important to discuss and review project deliverables on a daily basis throughout the project. The customer should provide timely feedback and approval for any suggestions or requirements from Huawei. Based on the actual situation of the project, some or all deliverables must be reviewed by the project team and business department and be reported to relevant leaders before being accepted and signed. The customer should organize (including coordinating consultants) and complete all internal reviews and reporting in time before the acceptance time specified in the contract.
    • 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.
