The document by Amir Sedighi discusses the concept of dark data, defined by Gartner as the information assets that organizations collect but rarely use for analytics or other purposes. It highlights that a significant portion of this data remains unanalyzed, posing risks such as legal issues and operational costs while offering potential opportunities if properly processed and utilized. The author also mentions the need for proper data management technologies and strategies to bring dark data into decision-making processes.

Thus, organizations often retain dark data for

data typically incurs more expense (and sometimes
greater risk) than value.

27. Question
All companies know data is going to provide value.
Why there is so much of dark data?

28. Why there is so much of dark data?
• Lack of insight about data
• Lack of ambitions to improve
• Disconnect among departments
• Lopsided priorities
• Lack of technologies to Capture and Store
• Lack of resources/infrastructures to make it available
• Lack of CPU and technics to analyze the data

29. The issues you face with Dark Data
• Legal and Regulatory Issues
• Loss of Reputation
• Intelligence Risk
• Operation Costs
• Opportunity Costs

30. Some essential questions
• What can we gather?
• What may we extract from it?
• How we may prune it?
• How long should we keep it?
• What are the storage options?
• What are the processing options?
• How much is the value of each block of data
(Approximately)
• Running limited boundary scenarios
