Killing a bad product idea used to cost two weeks and a chunk of engineering goodwill. In 2026, it costs an afternoon.

AI app builders have rewired the product lifecycle. You can now validate a direction—or kill it—before anyone writes a line of production code. PMs are folding these tools into their daily work, using agentic AI to compress multi-week build cycles into single-day sprints: spin up a working web app, tweak the React components yourself, put a real user flow in front of real users. No tickets, no waiting.

Prioritizing the backlog is one of the core responsibilities of product managers. It helps the team focus on work that has the greatest potential to benefit the business and users. Prioritization is also a way to filter a long list of ideas and tasks, which usually outweigh the available time and energy.

There are many prioritization methods, each with its own pros and cons. We’ve selected four simple and popular methods that don’t require significant preparation and compiled them into this cheat sheet.

A Product Requirements Document (PRD) is one of the most essential documents in product work. It sets out the plans for a team that is ready to move from ideation to implementation of a feature or product.

The purpose of a PRD is to build a shared understanding of the reasons, process and outcome of the project and to answer all related questions so that stakeholders and the team have a common, synchronized view. It therefore touches all stages of product work: Discovery → Delivery → Analysis.

A metric is a way to measure anything and express it as a number. In a product or business, metrics are a key guide for assessing a company’s activities and outcomes.

The very notion of “metrics” inevitably raises many questions: why they are needed, how to choose them, how to calculate, track and interpret them.

This guide is for beginners in product or business metrics. It explores the concepts essential for working with data correctly.
