Why do companies need both product managers and product owners?
Many companies hire both product managers (PMs) and product owners (POs), and many people use the two titles as if they meant the same thing. They overlap, but they are not the same job. The product manager owns why and what: the problem, the strategy and the outcomes. The product owner owns how the backlog turns that into working software, sprint by sprint, with the development team.
I hold a Certified Scrum Product Owner (CSPO) certification and have worked as a product manager in payments for many years, often switching between the two roles in the same week. This article explains how the roles differ, when a company needs both, when one person should do both, and the mistakes that make the split fail.
Product Manager vs Product Owner at a Glance
| Product Manager | Product Owner | |
|---|---|---|
| Core question | Are we building the right thing? | Are we building the thing right, in the right order? |
| Time horizon | Quarters and years | Sprints and releases |
| Main outputs | Strategy, roadmap, business case, success metrics, go-to-market | Product backlog, user stories, acceptance criteria, sprint priorities |
| Faces | Customers, market, executives, sales, finance, partners | Development team, Scrum Master, QA, UX |
| Measured on | Business outcomes: revenue, conversion, retention, cost | Delivery: value shipped, predictability, quality |
| Origin | Business and marketing function | Defined role in the Scrum framework |
What a Product Manager Does
A product manager is responsible for the success of a product or product area in the market. The work usually includes:
- Discovery. Talking to customers, studying data and competitors, and finding the problems worth solving.
- Strategy and roadmap. Deciding which bets to make over the next few quarters and why, and explaining the trade-offs.
- Business case. Sizing the opportunity, estimating cost and return, and getting investment approved.
- Success metrics. Defining how success is measured and tracking it after launch.
- Cross-functional alignment. Working with engineering, design, legal, compliance, finance, sales, marketing and support.
- Launch. Working with marketing and sales on positioning, pricing and rollout.
What a Product Owner Does
The product owner role comes from Scrum. The Scrum Guide describes the PO as accountable for maximizing the value of the product resulting from the work of the Scrum Team, mainly by managing the product backlog.
In practice that means:
- Owning the backlog. Writing and refining user stories, and ordering the backlog so the most valuable work comes first.
- Clarifying requirements. Answering the team’s questions quickly and writing clear acceptance criteria.
- Sprint participation. Setting the sprint goal with the team in sprint planning, and accepting or rejecting completed work in the sprint review.
- Trade-offs during delivery. Deciding what to cut or defer when scope, time and quality collide.
- Release decisions. Deciding when an increment is ready to ship.
Why Companies Need Both
At a small company, one person does both jobs. As the product and the organization grow, the two jobs start to compete for the same person’s time:
- The outward-facing work expands. More customers, more stakeholders, more regulation and more competitors mean more strategy and alignment work.
- The team-facing work expands. Several scrum teams need a responsive backlog owner every day. A PM who is in customer meetings and executive reviews cannot answer a developer’s question within the hour.
- Context switching is expensive. Strategy needs long, uninterrupted thinking. Backlog work needs constant short interactions. Doing both at scale usually means one of them suffers.
Splitting the roles lets the PM stay close to the market and the PO stay close to the team, with the backlog acting as the contract between them.
How the Two Roles Work Together
- The PM sets the outcome and the priorities for the quarter, for example “reduce false-positive fraud declines by 20% without increasing chargebacks”.
- The PM and PO break the outcome into initiatives and epics together, with the PM explaining the customer problem and constraints.
- The PO turns epics into stories, works out details with engineering and design, and orders the backlog.
- The team delivers in sprints; the PO accepts the work against acceptance criteria.
- The PM measures the result in the market and feeds what was learned back into the roadmap.
The handoff works best when it is not a handoff at all. The PM should attend key backlog refinements, and the PO should hear customer and stakeholder conversations directly, so the PO can make good decisions without escalating every question.
An Example from Payments
Take a project to add network tokenization to a subscription business. The PM builds the case: stale cards cause a known share of renewal declines, tokens should recover part of that, and the fee cost is lower than the revenue gain. The PM negotiates with the processor, aligns finance and security, and defines the success metric (renewal approval rate by issuer).
The PO owns the delivery: stories for provisioning new cards, back-provisioning stored cards, handling lifecycle updates, updating the “card ending in” display, and changing retry logic. When the processor’s sandbox does not support lifecycle webhooks, the PO decides to ship provisioning first and add lifecycle handling in the next sprint. That is a delivery trade-off the team needs answered the same day, not at the next steering meeting.
When One Person Should Do Both
- Early-stage startups and small products with one team.
- Technical or platform products where the “customers” are internal engineering teams.
- Teams where the PM has enough time to be available to developers daily.
In these cases, splitting the role adds a handoff without adding much value. The person just needs to protect time for strategy, because the daily backlog work will always feel more urgent.
Common Anti-Patterns
- The PO as a ticket writer. If the PO only transcribes the PM’s decisions into Jira, the team loses a real decision-maker and every question escalates.
- The PM who never meets the team. Strategy without engineering input produces roadmaps that do not survive contact with the codebase.
- Two people, no clear split. If both think they own prioritization, the team gets conflicting answers. Write down who decides what.
- Measuring the PO only on velocity. Shipping a lot of the wrong things is not success.
The PO should share the outcome metric with the PM.
- Too many teams per PO. One PO can usually serve one or two teams well. Beyond that, availability drops and quality follows.
Career Paths
Many product managers start as product owners, business analysts or engineers. Moving from PO to PM usually means taking on more market-facing work: customer research, business cases, pricing and go-to-market. Moving the other way is less common but useful for PMs who want to be closer to delivery. In payments and fintech, both roles benefit from domain depth: knowing how chargebacks, decline codes and processing fees work makes both strategy and backlog decisions better.

Product Owner vs Product Manager: Key Takeaways
- The product manager decides what to build and why; the product owner decides how the team delivers it and in what order.
- Small companies combine the roles; growing teams usually separate the product owner and product manager.
- The product owner is not a ticket writer, and the product manager is not a backlog manager.
- Clear ownership of outcomes and priorities makes both roles work.
FAQ
Is a product owner lower level than a product manager?
Not by definition. They are different scopes, not ranks. In some companies the PO title is used for more junior roles, but a senior PO leading a critical platform can carry as much responsibility as a PM.
Can a product owner become a product manager?
Yes, and it is a common path. The gap to close is usually customer discovery, business-case writing and go-to-market experience.
Does Scrum have a product manager role?
No. Scrum defines three accountabilities: product owner, Scrum Master and developers. Product management is a wider business function that exists outside the framework.
Who owns the roadmap?
Usually the product manager. The product owner owns the backlog, which is the detailed, ordered plan for delivering the near-term part of the roadmap.
