Choosing a new communications platform is not a gut decision – nor should it be. Where operational communications, data protection and reliability intersect, a robust and transparent basis for decision-making is required. This is precisely what a well-planned proof of concept (PoC) provides.
A proof of concept demonstrates, under real-world conditions, whether Teamwire meets your requirements for secure (operational) communication – from a technical and organisational perspective, and in day-to-day use. This guide takes you step by step through a structured PoC process tailored to the requirements of regulated and safety-critical organisations.
What a PoC is intended to achieve – and what it is not
Before you begin, it is worth establishing a clear distinction. A proof of concept answers a narrowly defined question: does the solution work for your specific, critical use cases? It is time-limited, focuses on a few key scenarios and serves to minimise risk before an investment decision is made.
This is to be distinguished, on the one hand, from the pilot, which involves a broader, longer-term trial with a larger user group. This usually takes place following a successful PoC and with a view to live operation. And, on the other hand, the roll-out is the widespread introduction of the system once a decision has been made.
A common mistake is to expect a PoC to already represent a fully operational system. A PoC is not intended to cover everything – it is designed to answer the key questions: Does the solution meet our security and compliance requirements? Will it be accepted by users? Does it function reliably in our mission-critical scenarios?
Phase 1: Preparation and definition of objectives
The success of a PoC is determined before the first message is sent. It is during this phase that you lay the foundations.
Defining success criteria
Set out measurable criteria against which you will evaluate the PoC at the end. Avoid vague objectives such as ‘the app should work well’. Instead, be specific; for example:
- The central alert system reaches defined recipient groups in under X seconds.
- At least X per cent of the test group are actively using Teamwire after two weeks.
- All data protection requirements are met.
- Integration with existing systems (MDM, directory service) can be achieved without the need for workarounds.
Involving the right stakeholders
In regulated organisations in particular, projects rarely fail because of technical issues, but because certain stakeholders have been overlooked. Bring all the relevant roles together at an early stage:
- IT and IT security for technical and safety assessments.
- Data Protection Officer for the GDPR compliance assessment and the data protection impact assessment.
- The staff council or works council, as the introduction of communication software is generally subject to co-determination. Involving them at an early stage helps to prevent obstacles arising later on.
- The specialist department – such as the operations management team, crisis management team, nursing management or departmental management – which is aware of the actual requirements.
- Department heads and managers of the respective working groups, who, on the one hand, are aware of their teams’ requirements for such a communication solution and, on the other hand, are often in a position to authorise the introduction of a tool such as Teamwire.
- Where applicable, senior management, the executive board and C-level executives, if Teamwire is to be rolled out company-wide or within senior management, or if its introduction requires approval from the very top. Furthermore, it sends a positive signal to all staff if senior management takes the trial seriously and plays an active role in the decision-making process.
Select the test group and use cases
Select a representative, diverse test group – not just the staff who are most tech-savvy. Define two to four key use cases that are truly critical to your organisation. Examples: rapid alerting during operations, secure transmission of sensitive information, coordination within the crisis management team, or shift handover involving sensitive personal data.
Define the duration of the test and organise a kick-off meeting
Set a clear trial period. You have 14 days to carry out a meaningful PoC with Teamwire. A defined timeframe creates a sense of commitment and ensures that the solution is actively used rather than simply installed.
Next, bring all those involved in the test together for a kick-off meeting. Here, you will lay the foundations for a successful test together.
An important prerequisite for the kick-off:
All participants should have downloaded the app and logged in beforehand. This will allow you to send an initial message or an alert to the group straight away during the meeting – a powerful ‘aha’ moment that demonstrates the solution works straight away.
Next, follow the four steps below.
Step 1: Explain the aim and purpose
What are your plans for the solution, what will it be used for, and which existing tool will it replace?
Step 2: Explain the benefits
Make the specific added value for participants clear. This boosts motivation and, as a result, the test’s validity.
Step 3: Live demonstration
Demonstrate Teamwire in action within the application. A brief, practical demonstration is far more convincing than a mere explanation.
Step 4: Announce the trial period
Give the go-ahead and make it clear that the test will now run for 14 days.
Phase 2: Technical set-up and safety check
For security-critical organisations, this step is the very heart of the PoC and the key feature that sets it apart from consumer messaging apps such as WhatsApp or Signal.
Select the appropriate operating mode
Teamwire generally offers several hosting options:
- A fully independent public cloud in Germany (BSI-C5-certified): data is stored exclusively on German servers, operated in accordance with European data protection standards.
- Private cloud: a dedicated, highly scalable environment.
- On-premises: Operated entirely within the organisation’s own infrastructure; relevant for organisations with the highest sovereignty requirements.
As standard, we carry out the PoC free of charge in the public cloud. You are, of course, also welcome to test the private cloud and on-premises options. However, the initial effort is slightly greater in these cases, and the test is not free of charge. Simply get in touch with our team to discuss the details — no obligation.
Check compliance and architecture
Use the PoC to verify the security and compliance features in practice, rather than simply rubber-stamping them on paper. Here are a few points to consider during the testing phase:
- Zero-trust architecture as the underlying security concept.
- Certifications such as ISO 27001 and BSI C5: Ask to be shown the certificates and their scope.
- GDPR compliance, including data processing on behalf of others and the question of whether personal data may leave the European legal area (keyword: US CLOUD Act).
- Comprehensive, state-of-the-art encryption and a realistic understanding of which metadata is protected and which is not.
- Data minimisation: Check that the solution only collects and processes the data that is actually required. Data minimisation is a key principle and reduces the risk associated with sensitive, personal information.
Testing integration
Check the integration with your existing IT infrastructure: Mobile Device Management (MDM), directory services for user management, Active Directory support and – where relevant – audit-proof archiving. Seamless integration is often crucial for future scalability.
Phase 3: Pilot operation using real-world scenarios
The solution is now in users’ hands. Important: Test it using realistic scenarios from your organisation’s day-to-day operations, not artificial test situations.
Depending on the sector, the focus here varies. For example:
Police and public safety
Alerting emergency services, transmitting live locations, coordinating during an ongoing operation, and securely exchanging information relevant to the operation.
Critical infrastructure
Crisis communication in the event of incidents, coordination of emergency response teams, and ensuring communication even in exceptional circumstances.
Public authorities
Secure internal communication; replacing insecure communication channels such as WhatsApp; mobile connectivity for field staff and those working from home.
Healthcare
Handover between shifts, rapid coordination within the treatment team, secure transmission of patient-related information.
Provide active support to users throughout the test phase. A brief introduction, a point of contact for queries and a simple way to provide feedback will significantly enhance the value of the proof of concept.
Phase 4: Evaluation based on the KPIs
Once the pilot phase has been completed, you should evaluate the results in a structured manner against your previously defined success criteria. Useful key performance indicators and evaluation criteria include, amongst others:
- Adoption rate: How many of the test users used Teamwire regularly and of their own accord?
- Response and reply times: How quickly did critical messages and alerts reach their recipients?
- Reliability: Did communication function reliably, even under heavy load or in exceptional circumstances?
- Security assessment: Have all the checkpoints from Phase 2 been met?
- User acceptance: How do users rate the usability and benefits? Qualitative feedback is just as valuable here as figures.
- Replacing shadow IT: Has insecure communication via private apps such as WhatsApp really been phased out?
Phase 5: Decision-making and scaling
Based on the assessment, you will make an informed decision. If the outcome is positive, you will prepare for the transition.
Business case or procurement proposal
Translate the PoC results into a decision-ready proposal for senior management, including a cost-benefit and risk analysis. In public authorities, this often forms the basis for the procurement process.
Scaling plan
Define how the roll-out will take place in stages – for example, from the pilot group to the entire organisation.
Training and Change Management
Make sure to schedule training sessions and communication initiatives so that the solution is accepted and used by all staff members.
Common mistakes that cause a PoC to fail
Based on practical experience, a number of pitfalls can be clearly identified:
- No clear objective: without defined success criteria, there is ultimately no basis for evaluation.
- Duration too short: A PoC lasting just a few days does not provide a reliable picture of user acceptance.
- Incorrect test group: If you only test IT professionals or technology enthusiasts, you will get a skewed result.
- IT testing without end users: Technical evaluation alone says nothing about acceptance in everyday use.
- Failure to involve data protection officials and the staff council: If this is neglected, the project risks failing due to organisational hurdles following a successful PoC.
- Lack of a basis for comparison: Without clear requirements, it is impossible to assess whether the solution is truly suitable.
