Executing this process can identify deficiencies in intelligence or data collection, which will need to be resolved before development can start. The following are the inputs and outputs associated with this phase:

Input: Triaged detection requirement
Output: Detection of technical specifications and data engineering requirements (if applicable)

The Investigate phase can be broken into four steps:

Identify the data source
Determine detection indicator types
Research
