The acronyms POC and SPOC circulate in professional exchanges without their scope always being clear. The former refers to a technical validation process, while the latter denotes an organizational role. Their initials are similar, but they address distinct issues within the company.
POC and SPOC: two acronyms, two radically different functions
A POC (Proof of Concept) is a structured experiment conducted to verify that an idea, technology, or process works before committing heavier resources. It is frequently found in IT projects, software solution deployments, or initiatives related to artificial intelligence.

A SPOC (Single Point of Contact) is a person, sometimes a small team, designated as the single entry point to centralize requests, feedback, or coordination between multiple departments. The SPOC exists in telecommunications, IT services, customer support, or cross-functional project management.
The POC answers the question “does it work?”. The SPOC answers the question “who should I contact?”. To delve deeper into the difference between POC and SPOC, one must examine how each fits into the daily lives of teams.

POC in the company: a validation protocol, not just a simple test
Reducing the POC to a quick trial misses the essence of its logic. A well-conducted POC follows a structured protocol, with defined success criteria established before the launch. Without these criteria, the experiment goes in circles and leads to no decision.
The components of a rigorous POC
- A limited functional scope: we do not test the entire solution, but a specific feature or a priority use case for the company.
- A limited duration, generally a few weeks, to prevent the project from drifting into disguised development without formal validation.
- A capped budget and measurable metrics, which allow for a GO or NO-GO recommendation at the end of the phase.
- Since 2024, regulatory compliance (GDPR, anticipation of the AI Act for AI projects) has become a non-negotiable criterion for assessing an industrializable POC.
This framework transforms the POC into a decision-making tool. The project team, management, and departments have factual elements to arbitrate: continue, adjust, or abandon.
Why so many POCs never go into production
A common observation in feedback from the field is that the transition from POC to production remains the breaking point for many projects, particularly in artificial intelligence. The reasons are rarely technical. They are more related to the absence of an internal sponsor, lack of documentation of results, or poorly calibrated success criteria from the outset.
A technically validated POC but lacking an operational roadmap ends up in a drawer. The rigor of the initial protocol directly conditions the company’s ability to scale.
SPOC in IT and telecommunications: simplifying collaboration
The role of SPOC has developed in environments where the multiplication of interlocutors generates confusion. An IT service that receives requests from ten different departments, without filtering or prioritization, loses responsiveness and trust from the business teams.
Designating a SPOC creates a single channel. This reference person centralizes requests, qualifies urgencies, directs to the right experts, and ensures follow-up. In telecommunications and managed services, the SPOC is often the guarantor of daily service continuity.
What the SPOC changes concretely
For field teams, the benefit is immediate: one number, one email, one person who knows the history of the case. Trust is built because the contact does not change with each call.
For the company, the SPOC also generates data. By centralizing requests, it identifies recurring problems, peak loads, and unmet support needs. This visibility feeds strategic advice and internal expertise on ongoing projects.
Field feedback diverges on one point: an overloaded SPOC becomes a bottleneck rather than a facilitator. The sizing of the role, in terms of scope and volume of requests, conditions its effectiveness.
Combined POC and SPOC: when the two intersect on a project
In practice, POC and SPOC often coexist within the same project. Take the case of a company launching a POC to test a new internal collaboration tool. The IT service SPOC naturally becomes the liaison between the vendor, the project team, and the pilot users.
The POC produces validation data. The SPOC ensures the smooth flow of exchanges and the escalation of issues. Without an identified SPOC, user feedback gets scattered across multiple channels, and the analysis of the POC loses reliability.
This complementarity is found in larger-scale digital transformation projects. The POC tests the solution, the SPOC secures human coordination around this solution. One without the other weakens the setup.
Confusing the two terms leads to concrete misunderstandings during scoping meetings. When a provider talks about “setting up a SPOC,” they propose a dedicated contact. When they propose a “POC,” they commit to a measurable testing phase. Clarifying these scopes at the project launch avoids weeks of organizational drift.
