Data maintenance
Compare with other Characteristic
Characteristic Name: | Data maintenance |
Definition: | Data should be accessible to perform necessary updates and maintenance operations in it’s entirely |
Dimension: | Availability and Accessability |
Granularity: | Record |
Characteristic Type: | Usage |
Implementation Form: | Process-based approach |
Verification Metric:
The number of tasks failed or under performed due to lack of data maintenance |
The number of complaints received due to lack of continuity in data access |
Validation Metric:
To what extent required capabilities and skills have been implemented to improve the data usage of a task |
BackgroundGuidelines
The original definitions given below formed the basis of the consolidated definition of the characteristic.
Definition: | Source: |
---|---|
A measure of the degree to which data can be accessed and used and the degree to which data can be updated, maintained, and managed. | D. McGilvray, “Executing Data Quality Projects: Ten Steps to Quality Data and Trusted Information”, Morgan Kaufmann Publishers, 2008. More from this source |
Can all of the information be organized and updated on an on-going basis? | EPPLER, M. J. 2006. Managing information quality: increasing the value of information in knowledge-intensive products and processes, Springer. More from this source |
The implementation guidelines are guidelines to follow in regard to the characteristic. The scenarios are examples of the implementation
Guidelines: | Scenario: |
---|---|
Technological changes in the infrastructure/system should be handled in such a way that they should not make data inaccessible | (1) Sales order is created once a customer signs a contract. Then it is updated in three instances 1)Delivery date and shipment date is updated once the production plan is created. 2) Actual quantity is updated once the manufacturing is complete 3) Total cost is updated once the freight changes are incurred. A sales order is achieved after one years from delivery. |
A maintenance policy for mission critical data should be developed and implemented to handle on going systematic updates (Create, read, update, delete, archive and cleanse) | (1) Customer data : Created when a customer enters into a contract, updated once the customer details change or contact change, archived once the contact end |
When multiple versions of the same data is available through different datasets\databases create a master record and make it available across the systems | (1) Master data management |
Leverage application and storage technology in such a way that the maintenance policies can be applied on data | (1)Addresses which were not updated during the last 24 months are prompted for validations |
Create a responsibility structure/Authorisation structure and a communication structure to manage the process of information generation maintenance and utilisation | (1) It is the responsibility of the work study team to provide SMV (standard minute values) for a garment. (2) Approved SMVs should be sent to the planning department for planning purposes. |
