Data Driven Decision making

Data-driven decision-making involves making business decisions using a quantitative approach that involves number crunching and data processing to generate numerical information. Although predictive models can be used to calculate the potential consequences of a decision and present them as predictive data, the focus is more on inputting variables and producing numerical results. In other words, data-driven decision-making is primarily concerned with the numbers and outcomes of a decision. external-link

Data Driven Organization

A "data-driven organization" is one that has immediate access to the right data, in the right format, at no additional cost. In such organizations, business leaders have real-time insights into trends and anomalies, allowing them to focus their resources where they will be most effective. These organizations have mastered the art of quickly accessing summary information while also being able to drill down to the supporting details when necessary. An example of a perfect data-driven organization is one where significant issues are immediately identified and prioritized. external-link

Data Factory

A Data Factory is a framework with activities required to turn raw data into a data product that can be either fed into an artificial intelligence application or traded. In essence, raw data rights must be verified before any data can be ingested or harvested (rights, licensing, user consent). Then data ought to be harmonized, properly labeled, or tagged for it to be made discoverable through a catalog of categories and search engines (harmonization). Furthermore, it needs to be scored to provide some indication of quality, because without it any subsequent analytics is ineffected – “garbage in, garbage out”. Finally, governance mechanisms are required to ensure that data can be exchanged while data sovereignty is maintained for each data provider. external-link
