Guides for the people who decide what gets built.

Practical, opinionated guides on prioritization, requirements, validation, feedback, and roadmaps — for the people who decide what gets built.

Prioritization & deciding what to build

Product prioritization frameworks: how to choose the right one RICE, MoSCoW, Kano, Value vs Effort, WSJF — there are more frameworks than there is time to use them. Here's how to pick one that fits the decision in front of you. RICE scoring explained, with a worked example Reach × Impact × Confidence ÷ Effort. The formula is simple; using it honestly is the hard part. Here's how each factor works and a full example you can copy. How to score a backlog with RICE, step by step From a messy list of ideas to a ranked backlog you can defend — the practical workflow, including how to keep the scoring honest and fast. RICE vs MoSCoW vs Value/Effort: which to use when Three popular frameworks, three different jobs. A side-by-side on what each is good at, where each breaks, and how to pick for the decision in front of you. The Value vs Effort matrix: the 2×2 that still works The simplest prioritization tool there is, and for small teams often the only one you need. How to use it well — and where its simplicity bites. The Kano model, explained for product teams Not all value is the same kind of value. Kano sorts features into basics, performance, and delighters — and tells you where investment actually pays off. WSJF and cost of delay, in plain English When being late is itself expensive, you need a framework that prices time. WSJF does exactly that — here's how it works without the SAFe jargon. How to prioritize features without customer data Nearly half of product managers say their hardest problem is prioritizing without enough customer feedback. Here's how to make defensible calls anyway — and how to fix the underlying gap. Prioritization mistakes that quietly skew your roadmap The worst prioritization errors don't announce themselves — they hide inside a process that looks rigorous. Here are the ones that do the most damage. How to say no to feature requests, with a process Saying no is most of the job, and doing it well protects both your roadmap and your relationships. The trick is a process that makes the no impersonal and defensible. Estimating reach and impact when your data is thin The two RICE factors people fudge most are reach and impact. Here's how to estimate them defensibly without pretending you have data you don't.

Writing requirements & specs

How to write a PRD: a practical, modern guide A product requirements document is only useful if engineering can act on it. Here's a lean, modern structure that aligns the team without becoming a 30-page relic. PRD template with a filled-in example A reusable PRD structure, with each section shown twice — what goes there, and a worked example for a real feature you can adapt. What to include in a PRD — and what to leave out The most common PRD failure isn't missing sections; it's including the wrong things. Here's the line between requirements and solution design. PRD vs BRD vs MRD vs SRD: which document you actually need Four acronyms, four different jobs, and a lot of teams writing the wrong one. Here's what each document is for and which you actually need. The one-page PRD: when less is more For most features, a focused one-pager beats a 30-page document nobody reads. Here's what fits on the page, and when you genuinely need more. Writing success metrics into a PRD A PRD without a success metric is a wish. Here's how to define metrics that are specific, measurable, and actually tied to the problem you're solving. How to write user stories with acceptance criteria The user story format is simple; using it to actually align a team is not. Here's how to write stories engineers can build and acceptance criteria that settle 'done.' Epics vs user stories: how to split work that ships An epic is too big to build in a sprint; a story is just right. The skill is splitting the first into the second without creating fragments that deliver nothing. From PRD to engineering spec: closing the handoff gap The PRD says what to build; the spec says how. The gap between them is where requirements get lost in translation — here's how to close it. Requirements gap analysis: catch holes before engineering does The cheapest bug is the one you find in a document. A structured gap analysis catches missing requirements while they're still words, not code. PRD mistakes that cause rework Most rework is born in the requirements, not the code. Here are the PRD mistakes that reliably turn into wasted engineering weeks — and how to avoid them.

Validating the idea & the business

How to validate a startup idea before you build Building is cheap now; building the wrong thing is as expensive as ever. Here's how to find out whether anyone wants your idea before you spend months on it. Problem validation vs solution validation: do them in order Validating your solution before validating the problem is how smart founders build polished products nobody needs. Here's the right sequence. How to test willingness to pay, before writing code People love things they'd never buy. Pricing is the validation step founders skip most — here's how to test whether anyone will actually pay, before you build. TAM, SAM, SOM: market sizing without kidding yourself Market sizing is where founders either lie to themselves with a giant number or undersell a real opportunity. Here's how to do it honestly. SaaS pricing models: how to choose and set your price Pricing is the highest-leverage number in your business and the one founders agonize over least productively. Here's how the main models work and how to pick. Unit economics for non-finance founders CAC, LTV, payback period — the handful of numbers that decide whether your business works. Explained for builders who'd rather be shipping. Idea validation mistakes founders keep making Most failed validation isn't a lack of effort — it's effort pointed the wrong way. Here are the mistakes that produce false confidence and how to avoid them. How to run customer interviews that aren't just flattery Most customer interviews collect compliments. The good ones collect truth. Here's how to ask questions that surface real behavior instead of polite hypotheticals. Do you still need a business plan in 2026? The 40-page business plan is dead. The thinking it forced is not. Here's what's worth keeping and what to throw out. Go-to-market strategy: a first-90-days plan In 2026, building is cheap and attention is expensive. A go-to-market plan is how you avoid launching a great product to silence. Here's a practical 90-day version. The builder's blind spot: shipping is not selling AI made building cheap, which means a working product is no longer the achievement — it's the table stakes. The scarce skill now is everything around it.

Customer feedback & satisfaction

How to analyze customer feedback at scale Feedback piles up faster than anyone can read it. Here's a repeatable way to turn a mountain of reviews, tickets, and survey responses into decisions. NPS vs CSAT vs CES: which metric, and when Three satisfaction metrics, three different questions about your product. Here's what each actually measures and when to reach for it. Turning support tickets into a prioritized backlog Your support queue is the most honest product feedback you have, and most of it goes to waste. Here's how to turn tickets into ranked product work. How much customer feedback is enough to act on? Act on too little and you're chasing anecdotes; wait for too much and you never ship. Here's how to know when you have enough signal to move. Qualitative vs quantitative feedback: using both well Numbers tell you what's happening; words tell you why. Using one without the other is how teams optimize confidently in the wrong direction. Closing the feedback loop: telling customers you listened Collecting feedback and never responding teaches customers to stop giving it. Closing the loop is the cheapest loyalty lever most teams ignore.

Roadmaps & stakeholders

How to build a product roadmap, step by step A roadmap isn't a list of features with dates — it's a communication tool for what you're building and why. Here's how to build one that survives contact with reality. Now / Next / Later: the outcome roadmap explained The roadmap format that communicates direction without making promises you can't keep. Here's why Now/Next/Later beats the dated Gantt chart for most teams. Product roadmap template with an example A reusable roadmap structure you can fill in today, shown with a worked example — built around outcomes and phases, not a wall of dated bars. Timeline vs theme-based roadmaps: which to pick Dates or themes? The choice shapes what your roadmap promises and how often you'll have to apologize. Here's how to pick the right one. Roadmap mistakes that erode stakeholder trust A roadmap's real currency is trust, and most roadmap mistakes spend it. Here are the ones that quietly turn your roadmap into a credibility liability. Stakeholder communication for product and program managers Most of a PM's or TPM's influence comes from communication, not authority. Here's how to keep stakeholders aligned without drowning in status meetings.

Competitive analysis & positioning

How to do a competitive analysis, step by step A competitive analysis isn't a feature spreadsheet — it's a strategic read on where you can win. Here's how to do one that changes decisions. Competitive analysis template with a worked example A reusable structure for comparing your product against rivals, shown with a real example — built to end in a strategic conclusion, not just a grid. Finding your differentiation without fooling yourself Every founder believes they're differentiated. Most are describing a feature, not a moat. Here's how to find a difference that actually matters — and defends.

The PM role & the connected workflow

TPM vs PM vs project manager: the real differences Three roles, constantly confused, with genuinely different jobs. Here's what actually separates a technical program manager, a product manager, and a project manager. The connected PM workflow: from idea to shipped Most PM tools are point solutions — a PRD writer here, a prioritization spreadsheet there. The leverage is in connecting them into one flow. Here's what that looks like.
