Core competencies matter when they travel

Most firms confuse being good at something with having a core competence. The distinction matters. A core competence is collective learning that coordinates diverse skills and technologies into something competitors find genuinely difficult to replicate. Internal pride is not the test. The test is portability.

Three questions sort real competences from local strengths. Does the capability create recognisable value for customers? Does it travel across product lines rather than sitting inside a single business unit? And does it open new market opportunities rather than simply defending existing ones?

When all three hold, the competence compounds. Each new application deepens the underlying knowledge, which in turn makes the next application faster and cheaper. Honda's engine expertise is the textbook case: it moved from motorcycles to cars to generators to lawnmowers, each time reinforcing what the firm already knew.

The failure mode is subtler than neglect. Firms invest heavily in capabilities that perform well locally but never cross business-unit boundaries. The result looks like strength from the inside and fragmentation from the outside. A competence that does not travel is just a skill.
