In what form were the task assignments made to developers?

The task setting for developers is usually presented in the form of clear, specific, and measurable requirements. Formats that help avoid ambiguities are often used, such as:

• User Stories: describe functionality from the user's perspective, for example, "As a user, I want to be able to filter the product list by price so that I can quickly find suitable options."
• Technical specifications with acceptance criteria: describe what should be implemented and how to verify the result.
• Use of task tracking systems (Jira, Trello, etc.) with detailed descriptions, priorities, and deadlines.

It is important that tasks are broken down into small logical parts, have clear success criteria, and are understandable to the developer without additional clarifications.
