A core competency is something your company does better than most others, that customers notice, and that you can apply to more than one product. It sits in your team, processes, and know-how, not in a machine you bought. Everything outside it is a candidate for outsourcing.
Three tests separate a core competency from an ordinary activity. Does it give customers a benefit they notice? Is it hard for competitors to copy? Can you use it in more than one product or market? All three must hold. Most companies have one or two competencies, not seven.
An example. A bakery's competency is sourdough fermentation: a starter kept alive for years and a team that reads dough by hand. That one skill supports three products, namely bread, pizza bases, and dry mixes sold to restaurants. Delivery is not a competency. The team spends 10 of its 40 weekly hours driving routes. Outsourcing delivery costs 900 euros a month and frees those 10 hours for the wholesale line, which contributes 1,600 euros a month after ingredient costs. The net effect is 700 euros a month, plus a team doing what it does best.
The frequent mistake is calling everything a core competency. Customer service, hard work, and our technology fail the copy test, because every competitor writes the same words. If a competitor can claim it too, it does not distinguish you.
A second mistake is confusing competency with advantage. A competency is internal: you are good at something. It turns into a competitive advantage only when customers pay more, or buy more often, because of it. A bakery that ferments beautifully and sells at supermarket prices has a competency and no advantage.
Use the concept as a filter for decisions. Build what sits inside the competency. Buy or outsource the rest.
