How many participants were involved in your last project?

The number of participants in the last project depends on its scale and complexity. For example, a small project might have had 3-5 people: developers, a tester, and a manager. In a larger project, there could be dozens of people, including architects, developers, testers, analysts, and managers.

Speaking from my experience, about 7 people participated in the last project, which allowed for effective task distribution and communication.
