A method, apparatus, and computer program product of developing a hybrid interactive electronic technical manual. A set of sub-elements associated with core maintenance tasks is selected from a plurality of sub-elements in technical data for a device to form a set of core sub-elements. A cost-benefit analysis is performed on each sub-element in the set of remaining sub-elements to identify a sub-element benefit rating for the each sub-element. Sub-elements in the set of remaining sub-elements having a sub-element rating greater than or equal to a threshold benefit rating are selected to form a set of high benefit sub-elements. The set of core sub-elements and the set of high benefit sub-elements are converted from the non-interactive native file format to an interactive electronic technical manual database format. A set of links to the set of unconverted sub-elements is generated to form the hybrid interactive electronic technical manual.
