3a. Activity documentation: the personal lab book
The Data Scientist will always keep a personal auditable, time based, record of his/her work in the form of a “lab book” equivalent, incorporating all data addressed/analyzed and all of their analytical activities. This should include statements of the source and provenance of all data accessed and analyzed, the methods actually employed, all discoveries and other knowhow generated, any limitations of scope and findings, and suggested potential further investigations or applications. Such a lab-book is the property of the Data Scientist’s employer.
