Explicit knowledge (also expressive knowledge) is knowledge that can be readily articulated, codified, stored and accessed. It can be easily transmitted to others. Most forms of explicit knowledge can be stored in certain media. Explicit knowledge is often seen as complementary to tacit knowledge.
The information contained in encyclopedias and textbooks are good examples of explicit knowledge. The most common forms of explicit knowledge are manuals, documents, procedures, and how-to videos. Knowledge also can be audio-visual. Engineering works and product design can be seen as other forms of explicit knowledge where human skills, motives and knowledge are externalized.
