Dosi & Nelson, 2016
Technological paradigms:
"Specific knowledge bases building on selected chemical or physical principles, problem-solving procedures, search heuristics and often also some 'dominant design' of the artifacts produced on grounds of the paradigm itself" (p. 1).
- A specific body of practice and required artifacts in the input side;
- Distinct design notion for output artifacts; and
- A specific body of understanding, some private, but mostly shared by professionals in a field.
Design concepts.
-
Sometimes, dominant designs emerge: "a set of core design concepts embodied in components that correspond to the major functions performed by the product and by a product architecture that defines the ways in which these components are integrated" (p. 2).
-
- A paradigm reveals or embodies:
Relevant problems to be addressed;
Patterns of inquiry to address such problems;
A view of user needs;
A view of attributes of products and services;
Scientific and technical principles;
Specific technologies employed;
A general understanding about how and why prevailing practice works.

-
-
Search heuristics, which imply modes of creating and accessing technological opportunities.
-
Discriminating between technological paradigms: Nature of knowledge underlying opportunities for technological advances.
-
Cumulativeness.
Measure of the incremental nature of technological search: how much future probabilities of success are conditional on past realizations.
-
-
-
Technological trajectories:
Maps of "the relatively ordered patterns of advance in the techno-economic characteristics of products and in the efficiencies in inputs use". A process of progressive refinement and improvement in the supply responses to potential demand requirements.
When dominant designs emerge, trajectories appear to be driven by "hierarchically nested technological cycles" with invariant core components improving over time and a series of bottlenecks and technological imbalances.
Properties.
Trajectories do not eliminate variety, but give it direction with the aid of proximate boundaries of feasibility defined by paradigms.
Possible trade-offs between output characteristics are eventually narrowed down by market selection.
Forward extrapolation of trajectories may be uncertainty-reducing representations of the future; however, they are not unbiased representations and cannot foresee technological and economic success of specific actors.

Common features.
-
Trend toward substitution of inanimate by organic (human / animal) in energy production and information processing.

"A paradigm entails specific patterns of solution to selected techno-economic problems - that is, specific families of recipes and routines" (p. 1).
