Functional testing for reliable software

Assurance that your software works as users expect it to.

Software that works the way your users expect

When software doesn't do what it's supposed to do

Software should do what you promise. Functional testing gives you that certainty. It's about more than ticking boxes in a test plan: it's about understanding what really matters to your users and organization.

Many organizations experience that errors often come into the picture late. Processes appear to run differently than expected, dependencies are overlooked or users don't get what they expect. The result: surprises when going live and costly repairs.

With a good functional test approach, you can prevent that. By looking early at processes, risks and expectations, you can make software quality predictable. Functional testing answers two key questions: does the software work as intended and does it work the way users need it?

Our approach: grip and collaboration

Functional testing requires expertise and collaboration. We bring structure and overview to projects, so that teams and stakeholders gain confidence in quality. Our consultants fit in with your context: as a member of a scrum team, as coordinator of a chain test or as an advisor to your test approach. Always with an eye for the processes that really have an impact.

We combine expertise with tools and use AI where it adds value. This is how we ensure that testing does not slow down, but rather accelerates: clear, predictable and pre-tailored to what your organization needs.

Functional testing in practice

Functional testing is never one-size-fits-all. Depending on your context, we use exactly the approach that adds value. From user stories to chain tests: we ensure that the software not only works, but also matches the practice of your users.

User story validation

Make sure that stories meet real needs. We test whether acceptance criteria are sharp and testable, so that teams build what is really necessary.

Chain tests

Insight into dependencies between systems We ensure that links work and processes remain end-to-end reliable for your users.

Risk-based approach

Focus on what really matters. With risk profiles, we focus on testing where there is the most value or impact for your organization.

Acceptance Tests (GAT/UAT)

Involve users in quality. We guide key users in assessing and accepting new functionality that suits their work.

Test coordination

Peace and overview in complex processes. We manage multiple teams and ensure coherence and quality across different releases.

TA Health Scan

What functional testing brings to your organization

Functional testing provides control over software quality, predictability in your processes and trust among teams and stakeholders. By making risks visible early, you reduce surprises and reduce recovery costs. The result: software that works as intended and users who can use it immediately.

Key benefits:

  • Less repair work. Problems are discovered early, fixes are faster and cheaper
  • Confidence when going live. Teams and stakeholders know that the basis is right
  • Better collaboration. Business and IT look at quality together
  • Predictable trajectories. No surprises upon delivery, but peace and overview
  • Happy users. Software that really matches their daily practice

We specialize in functional tests, acceptance tests (FAT, GAT/UAT) and chain tests. Our experts coordinate quality assurance across multiple teams and releases and use tooling and AI smartly to make processes faster.

What sets us apart is how we bring peace and confidence to complex processes. We communicate clearly, include stakeholders and coach colleagues in the testing process. This is how we make quality tangible throughout your project and ensure that teams themselves become stronger in ensuring software quality.

FAQ

Frequently asked questions about functional testing

Functional testing often raises the same questions. When is the best time to start? How do you collaborate with scrum teams? And what does it deliver in concrete terms? We've listed the most important questions and answers so you can quickly know where you stand.

What is the difference between functional testing and technical testing?

Functional testing looks at whether software does what users expect and need. We test whether processes are correct, whether user stories match reality and whether different systems work well together. Technical testing focuses more on performance, security, and system behavior.

When is the best time to start functional testing?

Functional testing actually starts before code is written. We help you clarify user stories and acceptance criteria. During development, we test iteratively, so that problems come to light early and not just upon delivery.

What are FAT and GAT/UAT

These are different types of acceptance tests: FAT (Functional Acceptance Test) checks whether all agreed functionality is present. GAT (User Acceptance Test)/UAT (User Acceptance Test) allows end users to assess whether the software fits their daily work.

How does chain testing work in practice?

In chain tests, we check whether different systems work well together in a complete process. For example, we test whether data is transferred correctly from system A to B to C, and whether the end result matches what the user expects.

Can you participate in our scrum teams?

Yes, we move flexibly with the way you work. We can work as a test specialist in your scrum team, but we can also coordinate test activities across multiple teams or provide advice on your testing approach.

How do you ensure that functional testing does not slow down?

By starting early and testing iteratively, you can prevent delays. We help clarify pre-requirements, test during development, and use automation where possible to provide feedback faster.

What happens when problems are found?

We clearly document findings and advise on priority and approach. More importantly, we help your team understand why something went wrong so that similar problems can be prevented in the future.
