Project deliverables (PMBOK) vs project products (PRINCE2)
The same thing sits at the heart of both frameworks: the results a project must hand over. PMBOK calls them deliverables, PRINCE2 calls them products, and although the two concepts overlap heavily, they are not identical. The differences say a lot about how each framework thinks about control and accountability. This article compares project deliverables (PMBOK) with project products (PRINCE2): how each is defined, where the concepts genuinely differ, how they map to each other, and which term to use in your own project documentation.
Key takeaways:
- Both terms describe verifiable project outputs — results a project must produce and hand over for acceptance. PMBOK treats the deliverable as one concept in its vocabulary, while PRINCE2 makes the product the foundation of the whole method.
- A PMBOK deliverable is any unique, verifiable output — a product, result, or capability required to complete a process, phase, or project, produced throughout the lifecycle.
- A PRINCE2 product covers a wider scope — it includes specialist products handed to users and management products such as plans, registers, and reports, each with defined quality criteria.
- Key differences — PRINCE2 counts management artifacts as full products and requires a product description for every output; PMBOK classifies those artifacts as project documents and leaves the level of definition to professional judgment.
- How the concepts map — specialist products correspond to product deliverables, management products to process deliverables. A single vocabulary fixed in the project charter prevents confusion.
Why PMBOK and PRINCE2 name project outputs differently
The naming difference is not an accident of translation but a reflection of what each framework is. PMBOK is a descriptive body of knowledge: it catalogs concepts, practices, and artifacts, and trusts the project manager’s judgment on how to apply them. PRINCE2 is a prescriptive method: it defines processes, roles, and a chain of accountability, and it needs a load-bearing concept those processes can attach to. That concept is the product. So while both frameworks talk about verifiable outputs, PMBOK treats the deliverable as one term among many, and PRINCE2 builds the entire method on planning, delegating, and accepting products. Understanding that asymmetry is the key to every difference described below.
What is a deliverable in PMBOK?
In PMBOK terms, a deliverable is any unique and verifiable product, result, or capability to perform a service that is required to complete a process, phase, or project. Unique means it is defined for this specific project; verifiable means its completion can be checked against criteria rather than declared. Deliverables appear throughout the lifecycle: an approved project plan or a test report is a deliverable of its phase just as the final system is a deliverable of the whole project.
The concept also shapes how PMBOK plans work. The work breakdown structure is defined as a deliverable-oriented decomposition of project work, which means the plan descends from outputs to tasks, not the other way around. Deliverables are then verified in quality control and formally accepted by the customer or sponsor. What PMBOK does not do is prescribe a standard document for defining each deliverable; the level of documentation is left to professional judgment. For a full treatment of the concept, including types and identification techniques, see our guide to project deliverables.
What is a product in PRINCE2?
PRINCE2 elevates the same idea to a principle. One of the method’s seven principles is focus on products: a PRINCE2 project agrees and defines its products before planning the work, and everything the project creates or changes counts as a product. The concept splits into two categories with different audiences.
Specialist products
Specialist products are what the project exists to deliver to its users: the system, the building, the campaign, the new process. This is the part of the PRINCE2 vocabulary that matches the everyday, intuitive sense of a deliverable. Specialist products are handed over, accepted against quality criteria, and ultimately justify the project’s business case.
Management products
Management products are the artifacts used to run the project itself: the project plan, the business case, the risk and issue registers, checkpoint and highlight reports. PMBOK knows these items too, but files them as project documents or artifacts. PRINCE2 grants them full product status, with defined composition and quality criteria, on the logic that a project steered by sloppy reports fails just as surely as one that builds a sloppy system. This difference is where the two frameworks genuinely part ways.
Product descriptions and product-based planning
Every PRINCE2 product gets a product description: its purpose, composition, quality criteria, and who accepts it. Planning itself starts from products, through a product breakdown structure, and only then descends to activities. The product description works like a contract: it fixes, before work begins, what will count as done. Where PMBOK relies on the judgment of the project manager to decide how much definition an output needs, PRINCE2 assumes that defined products are what makes transparency and accountability possible.
Project deliverables vs project products: side-by-side comparison
| Deliverable (PMBOK) | Product (PRINCE2) | |
| Definition | Unique, verifiable product, result, or capability required to complete a process, phase, or project | Anything the project creates or changes, specialist or management |
| Rank in the framework | One concept in the vocabulary | Foundation of the method, backed by the focus on products principle |
| Management artifacts | Classified as project documents or artifacts | Full products with descriptions and quality criteria |
| Planning role | WBS is deliverable-oriented | Planning starts from the product breakdown structure |
| Definition standard | Left to professional judgment | Mandatory product description per product |
| Acceptance | Verified and formally accepted by customer or sponsor | Accepted against quality criteria named in the product description |
Read together, the table shows concepts that overlap in perhaps four cases out of five. A tested application is both a deliverable and a specialist product; the difference in vocabulary changes nothing about the work. The divergence appears at the edges: in the status of management artifacts, and in how much definition rigor the framework demands by default. PRINCE2 buys predictability at the price of documentation overhead; PMBOK buys flexibility at the price of relying on the judgment and discipline of the individual project manager.
What the difference means in practice
How the two concepts map to each other
If your organization distinguishes product deliverables from process deliverables, or external from internal ones, you are already using the PRINCE2 split under different names: specialist products correspond to product and external deliverables, management products to process and internal ones. The mapping is close enough that teams can translate documentation between the two vocabularies almost mechanically, as long as someone states the mapping once instead of leaving each reader to guess it.
Which term to use in your project documentation
Use the vocabulary of the framework your organization actually follows, and say so explicitly in the project charter. Problems start in hybrid environments, where a PRINCE2-trained PMO reads “deliverable” in a supplier’s PMBOK-style plan and assumes management products are missing, or the other way around. One sentence in the charter, stating which term the project uses and what it covers, costs nothing and prevents acceptance meetings from turning into terminology seminars. The words matter less than the discipline they carry: a named output, defined criteria, a named owner.

Managing deliverables and products in one system
Whichever vocabulary wins in your organization, the operational need is identical: a place where every output has a description, acceptance criteria, a deadline, an owner, and a visible status. In FlexiProject, the Products module carries exactly that for the specialist side: each deliverable is defined with its scope and acceptance criteria, linked to the tasks and milestones that produce it, and monitored separately from task completion, so an executed task is never mistaken for an accepted result. The management side benefits too: recurring status reports are generated from live project data instead of being assembled by hand, which is precisely the quality PRINCE2 expects from management products. Project templates close the loop by standardizing the product list for repeatable projects, so every new project starts with its outputs, requirements, and document patterns already defined.
Project deliverables vs project products: FAQ
Is a PRINCE2 product the same as a project deliverable?
For specialist products, in practice yes: both describe a verifiable output handed to users and accepted against criteria. The concepts stop being identical at management artifacts, which PRINCE2 counts as products and PMBOK classifies as project documents.
What are management products in PRINCE2?
Artifacts used to steer the project: the project plan, business case, risk and issue registers, checkpoint and highlight reports. Each has a defined composition and quality criteria, exactly like the products handed to users.
Does PMBOK have an equivalent of management products?
Yes, in substance: PMBOK describes the same plans, registers, and reports as project documents or artifacts. The difference is that PMBOK does not treat them as deliverables of equal standing with the project’s outputs, and does not require a formal description for each.
Can you combine PRINCE2 products with PMBOK practices?
Yes, and hybrid setups are common: many organizations plan from a product breakdown structure while using PMBOK vocabulary elsewhere. The combination works as long as the project fixes one shared vocabulary and keeps a single list of outputs with owners and acceptance criteria.
Project deliverables in PMBOK and project products in PRINCE2 describe the same fundamental thing: verifiable results a project must hand over. The genuine differences are two. PRINCE2 grants management artifacts full product status, while PMBOK files them as project documents; and PRINCE2 mandates a product description for every output, while PMBOK trusts the professional judgment of the project manager.
Everything else is vocabulary, and vocabulary is cheap to align: one sentence in the project charter fixing the terms used prevents most of the friction between the two approaches. What cannot be skipped in either framework is the discipline underneath the words: outputs defined before work starts, acceptance criteria agreed in advance, owners named, and status visible next to the schedule. A PPM system that keeps that discipline in one place, the way FlexiProject does with its Products module, recurring reports, and project templates, serves both vocabularies without forcing a team to choose between them.
