Product Management glossary
The terms the field uses every day, defined the way PMCert exams understand them. When a certification goes deep on a term, the entry points to it.
- Product Management
- The discipline of deciding what to build, for whom and why, connecting a customer problem to a sustainable business and answering for the outcome.
- Product Manager
- The person who answers for the product: investigates the problem, sets strategy, prioritises, follows delivery and measures the result.
- Assessed in certification CPM-F →
- Product Owner
- A role defined by Scrum: answers for the team backlog, orders the work and accepts what was delivered. The fundamentals are the same as the product profession.
- Assessed in certification CPM-F →
- Product Discovery
- The work of reducing uncertainty before building: interviews, observation, demand signals and the decision to carry on, stop or drop an idea.
- Assessed in certification CPDX →
- Product Strategy
- The choice of where to play and how to win: segments, positioning, value proposition and what deliberately stays out.
- Assessed in certification CPM-E →
- Product vision
- The description of the future state the product wants to cause in the world, stable enough to guide decisions and short enough to be remembered.
- Roadmap
- Strategy translated into a sequence of bets over time. It communicates intent and order, not item-by-item promised dates.
- Backlog
- The ordered list of candidate work for the product. Ordered is the word that matters: without explicit priority, it is just a warehouse.
- Prioritisation
- Deciding the order of work with explicit criteria, weighing value, cost, risk and learning, and saying no with grounds.
- MVP
- The smallest version of the product able to test the central hypothesis with real customers. The goal is to learn fast, not to ship little.
- Product-Market Fit
- The state in which an identifiable segment adopts the product, misses it and recommends it, sustaining growth without commercial brute force.
- OKR
- A goal-setting method separating the objective (qualitative direction) from key results (the measures that prove progress), aligning teams without prescribing tasks.
- Product metrics
- The measures that show whether the product creates value: adoption, activation, retention, revenue and recommendation, read together and never in isolation.
- Assessed in certification CPM-E →
- North Star Metric
- The single metric that best represents value delivered to the customer, used to align teams. It works alongside guardrail metrics, not alone.
- Retention
- The share of customers who keep using the product over time. It is the metric that separates real value from initial curiosity.
- Churn
- The loss of customers in a period. The opposite of retention, and the first place a value problem shows up as a number.
- Experimentation
- Testing decisions with control groups before committing: experiment design, sizing, threats to validity and statistical reading of results.
- Assessed in certification CPXS →
- A/B test
- The most common experiment: two versions served to random groups and compared on a decision metric defined beforehand.
- Assessed in certification CPXS →
- Persona
- A synthetic portrait of a customer segment, built from real evidence, that gives product decisions a name and a context.
- Customer journey
- The full path of whoever uses the product, from first contact to recommendation, with what the person does and feels at each stage.
- Assessed in certification CCXS →
- Kanban
- A flow management method: visualise the work, limit what runs in parallel and measure predictability to improve delivery continuously.
- Assessed in certification CKMS →
- WIP
- Work in progress: work started and not finished. Limiting WIP is the central lever of Kanban, because parked work ages and hides problems.
- Assessed in certification CKMS →
- Design Thinking
- A group problem-solving approach: frame the challenge, immerse in the context, synthesise, ideate, prototype and test with those who live the problem.
- Assessed in certification CDTS →
- Go-to-Market
- The plan for taking the product to market: entry segment, channels, message, price and the role of marketing and sales in the launch.
- Product Operations
- The discipline that scales the product practice: accessible data, tooling, rituals and processes that free teams to decide better.
- Product Analytics
- Using behavioural data to understand how the product is really used: funnels, cohorts, segmentation and the discipline of not fooling yourself with numbers.
- Assessed in certification CCXS →
- Stakeholder
- Anyone with a legitimate interest in product decisions: board, sales, legal, operations. Managing them is negotiating, not obeying or ignoring.
- Assessed in certification CCNS →
- Continuous discovery
- The practice of keeping weekly contact with customers and fresh evidence, instead of treating discovery as a phase that happens once before building.
- Assessed in certification CPDX →
