QA can be involved in the planning process and highlight risks so that the developer already understands what to write. Do you agree?

Yes, I agree. Involving QA in the planning process helps identify potential risks and problematic areas early in development. QA specialists can highlight scenarios that are difficult to cover with tests, point out possible integration challenges, non-standard cases, or performance requirements.

This allows developers to consider these aspects immediately when writing code, which reduces the number of bugs and rework in the future. Such an approach improves team communication and enhances the overall quality of the product.
