“Courses” describes a delivery format. It does not identify the person, task or situation that makes an offer useful. A manager preparing for a difficult contract renewal next week may need something quite different from someone developing leadership skills over the coming year. Both might search for negotiation training, but that shared label does not make their needs identical.
I would define the problem before expanding the catalogue. Who faces it? What makes it urgent? What do they already use instead? What can the business realistically help them do? Those questions also clarify what the offer should not promise.
Specialisation does not automatically improve retention or reduce support costs. A narrow audience may require substantial individual assistance or need the product only once. The business should examine actual use, questions, application and support effort. Course completion alone does not establish a change in professional practice.
A focused offer can still evolve. The test is whether an addition serves the chosen need or merely uses content that happens to be available. Entering another market requires the same discipline: language, working conditions and expectations need review. Translating the words does not prove that the offer fits the people expected to use it.
