Transparency and traceability #

Real-life example: Imagine a grocery store that regularly updates its inventory data, including product details, prices, and stock levels. To keep customers satisfied and maintain efficient operations, the store must trace all inventory information back to its source.

Why is data lineage the solution? #


Data lineage creates a comprehensive map of how inventory data travels and transforms within the store’s system, helping data users in the stores track changes, understand relationships between data elements, and identify errors or inconsistencies. This ensures transparency and traceability across the organization.

Data lineage mandates #


Utilizing data lineage tools that offer complete visibility, maintain an audit trail, and automate data mapping procedures aligns with data governance best practices.

Data quality #

Real-life example: A healthcare organization collects and processes patient data from multiple sources. Inaccurate or inconsistent data can lead to misdiagnosis or improper treatment.

Why is data lineage the solution? #


Data lineage helps organizations identify data quality issues by tracking data transformations and validating data accuracy throughout the data lifecycle.

Data lineage mandates #


Employing data lineage solutions that detect and resolve data quality issues while enforcing data validation rules adhere to data governance best practices.

Compliance and regulatory requirements #

Real-life example: Companies that handle sensitive customer information must adhere to data protection regulations, such as the General Data Protection Regulation or HIPAA, to avoid hefty fines and reputational damage.

Why is data lineage the solution? #


Data lineage enables organizations to demonstrate compliance by providing a detailed audit trail of data processing activities and maintaining proper documentation.

Data lineage mandates #


Implementing data lineage tools that support regulatory frameworks and ensure adherence to data privacy and security guidelines comply with data governance best practices.

Impact analysis #

Real-life example: A retail business wants to update its data processing pipeline, which could affect systems such as inventory tracking, sales report generation, and customer relationship management. Before making changes, it is essential to evaluate the potential impact on these downstream systems and processes.

Why is data lineage the solution? #


Data lineage allows organizations to understand data dependencies and evaluate the impact of proposed changes, minimizing potential disruptions.

Data lineage mandates #


Adopt data lineage solutions that enable organizations to simulate and analyze the effects of changes on data workflows to align with data governance best practices.

Root cause analysis #

Real-life example: An e-commerce company discovers discrepancies in its sales reports. To resolve the issue, they must trace the problem back to its origin.

Why is data lineage the solution? #


Data lineage helps pinpoint the root cause of data discrepancies by visualizing the entire data journey and identifying points where errors may have occurred.

Data lineage mandates #


Utilizing data lineage tools that facilitate quick and accurate root cause analysis adheres to data governance best practices.

You can also learn how automated data lineage can help with fast root cause analysis. Read here.

Collaboration and communication #

Real-life example: Imagine a marketing team and a data analytics team working together on a project analyzing the success of an advertising campaign. For them to work effectively, they need to communicate and collaborate seamlessly.

Why is data lineage the solution? #


Data lineage, especially column-level lineage, helps both teams understand the journey of data, including where it comes from and how it’s transformed. This shared understanding makes it easier for them to exchange insights, resolve issues, and work together efficiently.

Data lineage mandates #


Using data lineage tools that encourage teamwork and clear communication between departments is crucial for successful data governance. These solutions help create a smooth collaboration process, ensuring everyone stays on the same page and works towards the same goals.

Supporting advanced data initiatives #

Real-life example: A manufacturing company wants to implement advanced analytics and machine learning to optimize its supply chain.

Why is data lineage the solution? #


Data lineage helps organizations ensure the reliability and accuracy of their data, which is crucial for the success of advanced data initiatives like analytics and machine learning.

Data lineage mandates #


In this scenario, data lineage should provide a comprehensive view of the data’s journey, allowing the company to build trustworthy data pipelines for its advanced analytics initiatives.
