Answering the riskiest technical question first

A proof of concept is a small, time-boxed build that tests whether a specific technical idea is feasible. Can this AI model read our invoices accurately enough? Will this legacy system expose the data we need? Can the app process this volume in real time? A POC answers one or two questions like these with real code and real data, without the cost of building screens, user management or everything else a full product needs.

POCs are useful for CTOs evaluating a new technology, product teams facing an unknown integration, and business leaders who need evidence before approving a larger budget. They are also common before enterprise procurement, when a buyer wants to see the approach working on their own data, and before grant or investor applications that ask for technical evidence.

Nexzem agrees the exact question, success criteria and time box with you before writing code. We build only what the test needs, using your real data wherever possible, measure the results honestly and deliver a short report covering findings, limits, risks and a recommended path, whether that is proceed, adjust or stop.

Where Proof of Concept (POC) fits

  • Detail A

    Testing AI invoice extraction accuracy

    A finance team tests whether AI can extract totals, tax amounts and supplier details from several hundred real invoices accurately enough to automate entry, comparing results against manually verified values before funding a full rollout.

  • Detail B

    Connecting to a legacy ERP

    A distributor checks whether its older ERP can exchange orders and stock levels with a new ecommerce portal through available interfaces, uncovering data gaps and performance limits before committing to the portal project.

  • Detail C

    Sensor connectivity in a factory

    A manufacturer installs a few sensors on critical machines to confirm that data can be captured reliably despite electrical noise and metal structures, and that readings reach the cloud consistently before ordering hardware for every line.

  • Detail D

    Blockchain network throughput test

    A consortium planning a shared ledger simulates expected transaction volumes on candidate networks, measuring confirmation times and costs, to decide whether a public layer 2 or a permissioned network suits its requirements.

  • Detail E

    Evaluating a new payments provider

    A platform tests a new payment provider's APIs for split payments, refunds and payout timing in a sandbox, confirming that its marketplace flows and reconciliation needs can be met before migrating live transactions.

Writing a good POC question and success criteria

A proof of concept is only as useful as the question it answers. Vague goals, such as exploring whether AI can help, lead to vague results. A strong POC question is specific and decision-oriented: can we extract invoice totals from our supplier documents with enough accuracy to remove manual entry for most invoices?

Success criteria should be agreed before work begins and written down. They might include accuracy thresholds, processing time, cost per transaction, integration reliability or user acceptance. Without them, teams tend to declare success based on impressive demos rather than evidence that matters for the business.

Constraints belong in the definition too. Which data will be used, which systems are in scope, what timeline and budget apply and what is explicitly excluded. These boundaries keep the POC small and prevent it from drifting into an underfunded product build.

Finally, identify the decision the POC informs and who will make it. Knowing that the result will decide whether to fund a full project, choose a vendor or abandon an idea helps everyone focus on producing the evidence that decision maker actually needs.

Types of POCs and what they prove

Not all POCs test the same kind of risk. Some focus on whether a technology can achieve a result, others on whether systems can work together or perform at the required scale. Identifying the risk type shapes the approach, the data needed and the evidence produced, as summarized below.

Feasibility POCs, common in AI and data projects, test whether models can reach the required quality on real data. They need representative samples, including messy and difficult cases, rather than cleaned examples that flatter the results. Include the hardest real cases on purpose.

Integration POCs connect to real systems, such as an old ERP or a partner API, to confirm that data can flow reliably and securely. They often uncover authentication limits, missing fields or slow responses that would have derailed a full project.

Performance POCs simulate expected load to verify that an architecture or technology meets speed and scale requirements. They are particularly valuable before committing to new databases, platforms or blockchain networks whose behavior at scale is uncertain. Testing with realistic data volumes matters as much as realistic traffic.

  • N2.aTechnical feasibility: can it be done at all?
  • N2.bQuality: is the result accurate enough?
  • N2.cIntegration: can systems exchange data reliably?
  • N2.dPerformance: does it meet speed and scale needs?
  • N2.eUsability: will people actually use it this way?

From POC result to decision

A POC should end with a clear recommendation, not just a demo. The report summarizes what was tested, the results against each success criterion, what worked, what did not and the main risks remaining. It should state plainly whether the evidence supports proceeding, changing the approach or stopping.

A negative result is valuable. Learning that an idea will not work, or will cost much more than expected, after a small investment saves far larger losses later. Organizations that treat failed POCs as wasted money discourage the honest experimentation that makes POCs worthwhile.

If the result is positive, the next step is usually an MVP or production plan. The POC informs architecture choices, effort estimates, data preparation needs and risks to manage. Some components, such as tuned prompts, data mappings or integration code, may carry forward after review.

Share results widely with stakeholders. A short presentation with real examples, including failures and edge cases, builds realistic expectations and helps secure support for the next phase from people who were not involved day to day. Record the findings where future teams can find them, because similar questions often return.

Proof of Concept (POC) FAQs

Something else on your mind? Ask a consultant and get a reply within one business day.

How long does a proof of concept take?

Most POCs are time-boxed to 2-6 weeks. The time box is agreed upfront so the effort stays proportional to the question being tested.

What does a POC cost?

The main drivers are the complexity of the question, data preparation needed, number of systems involved and whether you need a demo interface. Because POCs are tightly scoped, we give a fixed quote after a free consultation.

When should we do a POC instead of an MVP?

Do a POC when the biggest risk is technical, such as whether an AI model, integration or architecture will work. Do an MVP when the technology is known and the risk is whether users want the product.

What happens if the POC fails?

A clear negative result is still useful, because it stops a larger investment in the wrong direction. Our report explains why it failed and whether a different approach is worth testing.

Is our data safe during the POC?

We sign an NDA on request, use anonymized or sample data where possible, work in access-controlled environments and delete test data after the engagement if you ask.

Can the POC code be used in production?

Parts of it often can, especially core logic and integration code. We are clear about which pieces are production-ready and which were shortcuts made only for the test.

Who from our side should be involved in a POC?

Usually a business owner who defines success, a subject expert who understands the data or process, and an IT contact who can provide system access and security approvals. Their time commitment is modest but important, because quick answers and realistic test data keep the POC on schedule.

Can a POC be used to compare vendors or technologies?

Yes. A comparative POC runs the same tasks and data through two or three options, such as different AI models, platforms or databases, and scores them against agreed criteria. This produces objective evidence for selection rather than relying on vendor demonstrations and marketing claims.

What do we need to provide before the POC starts?

Typically representative data samples, access to relevant systems or sandbox environments, documentation of current processes and a named contact for questions. Where data is sensitive, we agree masking, secure transfer and storage arrangements, and sign an NDA before anything is shared.
