How do you approach early traction planning for new products?

I’m curious how other founders and builders approach early traction when launching a new product.

Specifically:

• Do you start with a structured traction plan, or iterate week by week?

• How much do you rely on templates vs. fully custom strategies per product?

• At what point do you decide that an idea is not worth pushing further?

From my experience, the hardest part isn’t execution itself, but deciding what not to do in the first weeks — especially when time and focus are limited.

I’d love to hear how others here think about traction planning, prioritization, and early signals that guide your decisions.
