A knowledge base for everyday product work.

The product approach does not start with a set of frameworks, but with the discipline of decision-making: what problem to solve, for whom, why now and how to verify the result. The directory helps you go through the whole cycle – from research to scaling – and choose a tool for a specific work situation.

Choose a task, not a fashionable framework

The content does not imply one “right” process for all companies. The interview method, roadmap format, or rhythm of planning depends on uncertainty, risk, team size, and product maturity. Start with the question that prevents you from making a decision now.

I am just entering a product or a new company.

• /handbook/getting-started/ is a first month plan with no hasty reforms.
• How to use the directory - itineraries for working situations.
• Skills Map – identify strengths and the next gap.
• Junior to Head Pathways – Link learning to scale solutions.
• Dictionary of Terms - agree on a common language.

We need to figure out what to build.

• Product Discovery – an overview of the risks of value, convenience, feasibility and viability.
• Problem framing – Separate the problem from the finished solution.
• Research Methods – choose the way to get the proof you need.
• /handbook/discovery/interviews/: Ask about real behavior, not intentions.
• Opportunity Solution Tree - link outcome, capabilities and tests.

You need to choose a direction and give up the excess

• Product Strategy – to assemble a coherent set of choices.
• JTBD and Value Suggestion – understand the client’s progress and the basis of choice.
• Segmentation and Positioning – define the field of competition.
• OKR and outcome-roadmap - move direction to measurable bets.
• Pricing & Packaging and unit economy - link value to the financial model.

Change must be brought to a result.

• Product Delivery is the path from a proven hypothesis to an effect.
• PRD and requirements - save context without premature design.
• RICE, ICE and WSJF - make priority assumptions visible.
• Scrum, Kanban, and Dual-track - adjust the flow to the nature of the work.
• Relizas and rollouts - limit the risk and prepare the rollout.
• QUALITY AND TECODE – making investment decisions in a common language.

We need to understand the data.

• [/handbook/metrics/metric-system/] — Link value, business and managed inputs.
• North Star and input metrics - decompose the overall outcome.
• Funnels, cohorts and retention – localize the loss by stage and time.
• A/A- and A/B-tests - to check the causal effect.
• Data Interpretation Errors – Do not mistake noise and bias for the result.
• SQL for Product – check out a simple question yourself.

We need to find a growth limit.

• Product Growth – Diagnostics of activation, retention and monetization.
• Onboarding and activation – shorten the path to the first value.
• Retention and lifecycle – operate at a natural frequency of use.
• Growth loops and channels – distinguish the traffic flow from the repeatable loop.
• Monetization Models – Select the unit of payment and incentives.
• Experiments and guardrails – predetermine the criteria for the solution and the limits of harm.

We need to improve the user experience.

• Customer journey and scenarios - see the path beyond the product screens.
• PM × Design – agree on joint responsibility for the problem and solution.
• Content Design Design words as part of the behavior of the interface.
• Design System – Scale consistency, not just components.
• Digital Availability – Do not create barriers in key scenarios.

We need to work with people and organizations.

• Product-Design-Tech triangle – distribute leadership by solution type.
• Ownership and RACI - make the rights to decide explicit.
• Stakeholder management - Manage dependencies and expectations.
• Exec update and QBR shorten the path from fact to solution.
• Hiring, leveling and coaching - develop the product function.
• Organization, Product Ops and governance – remove system friction between teams.

If the situation is already burning

Open the profile playbook:

• Retention falls
• I need to activate
• Difficult Risk Release
• Team does not trust data
• Distributed Quarterly Targets
• Too many stakeholders
• Select Next Big Bet
