The team designed for our users' actual behaviour, not for the persona we thought they were

Liselotte Bakker / Head of Platform Engineering - Harbour Digital BV

Jan 25, 2026

Project summary: The project had a board-facing delivery date tied to a strategic initiative. We needed a partner who would treat that date as their own, not ours.

The thing that retrospectively seems most significant is how little drama there was. Complex technology projects tend to accumulate incidents, escalations, and tense conversations. This one did not. Problems were surfaced before they became incidents. Scope changes were handled with process rather than conflict. Risks were managed rather than avoided. That level of maturity is rare in my experience and it made the delivery feel almost effortless from our side, which I know it was not from theirs.

PROS

Architectural decisions designed for longevity rather than just the current brief, thorough automated test coverage, post-launch stability that validated every technical choice made during discovery

CONS

The quality of documentation they produce means our team needed to set aside dedicated review time to do it justice — a minor scheduling point rather than a genuine criticism

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Harbour Digital BV is an established Construction organisation headquartered in Utrecht, Netherlands. My role as Head of Platform Engineering covers both strategic planning and operational technology delivery. We maintain high standards for our vendors because our clients hold us to high standards — a bar we expect our partners to meet.
What specific problem or business challenge led you to hire this company?
A competitive threat had accelerated our roadmap. We had planned a significant UI/UX Design investment for the following year. External pressure moved that timeline forward by six months and required us to find an external partner rather than attempting to build internally in the time available.
What services did the company provide for your project?
Primarily UI/UX Design, with adjacent work in solution architecture and quality assurance. They were responsible for the full build from requirements through to go-live, including integration with four existing systems in our technology landscape. The breadth they covered without requiring additional vendors was commercially and logistically valuable.
Why did you choose this company over other providers you considered?
The quality of the questions they asked during the briefing process was the first indicator. Vendors who ask precise questions in the sales phase tend to apply the same rigour during delivery. That hypothesis proved accurate. The technical proposal was substantive, the team structure was senior throughout, and the pricing was transparent.
How clearly did the company understand your requirements and business goals?
Thoroughly and precisely. The requirements document they produced was detailed enough that our QA team used it directly to write acceptance criteria. Every user story had a defined business objective attached. Nothing was left to interpretation. That discipline in the requirements phase paid dividends throughout development and testing.
How was your overall experience with their communication and project management?
Communication was proactive, timely, and appropriately calibrated. Technical updates for the engineering audience, executive summaries for the steering group, risk flags with proposed mitigations rather than just problem statements. The fortnightly sprint reviews gave our stakeholders visibility without requiring them to attend every working session.
Did the company deliver the project on time and within your expected budget?
On time and within the approved budget. The estimation accuracy was notable — they had broken the work down in sufficient detail during discovery that their forecast proved reliable throughout, rather than being a number that shifted with every change in scope. We received one change request and it was for scope we had introduced ourselves.
What tangible results or business impact have you seen since the project was completed?
We went live four months ago. User adoption exceeded the target we had set by 23 percent in the first month. Support ticket volume has dropped measurably. The features we had deferred because the previous architecture made them prohibitively expensive to build are now in development. The platform they built has opened our roadmap.
What did you like most about working with this company?
Their instinct for keeping the business objective visible throughout technical decision-making. I have worked with technically excellent teams who lose the strategic thread as complexity increases. This team maintained a clear connection between every architectural choice and the outcome we had agreed to achieve. That orientation made the trade-off conversations significantly easier.
Would you recommend this company to others, and would you work with them again?
Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Construction sector looking for UI/UX Design expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Platform engineering work that let our product teams move independently at last

Project summary: Cross-agency data sharing had been blocked by incompatible systems for four years. A secure integration platform was the prerequisite for every transformation initiative in our roadmap.

Our stakeholder group included board members, clinical leads, compliance officers, and end users — each with different technical literacy and different success criteria. This team navigated that stakeholder landscape as well as any vendor I have seen. They adjusted their communication register depending on the audience without losing the substance. They managed expectations honestly throughout. And they delivered a system that each group can point to as meeting their requirements. That breadth is genuinely uncommon.

PROS

Clear and consistent communication adapted appropriately for both technical and non-technical stakeholders, shared tooling that gave our team real-time visibility, reliable sprint delivery throughout

CONS

Time zone coordination required some deliberate overlap management from both sides in the first couple of sprints, after which we had an efficient async rhythm that worked for the whole project

Questions & Answers

Please describe your company, your role, and the industry you operate in.
I lead technology at Rheintal Digital AG, a growth-stage Government & Public Sector business based in Düsseldorf, Germany. As Chief Innovation Officer my remit spans product engineering, platform operations, and strategic vendor partnerships. We had reached an inflection point where our internal capacity was not sufficient to execute our roadmap at the pace our market required.
What specific problem or business challenge led you to hire this company?
Regulatory requirements in our Government & Public Sector segment had changed and the compliance timeline was set by our regulator, not by us. The DevOps Services changes required were significant enough to justify engaging a specialist partner rather than diverting our internal team from the product roadmap.
What services did the company provide for your project?
The core engagement was DevOps Services delivery, though their scope expanded to include technical consultancy during discovery that materially improved our requirements. They also took ownership of the third-party integration workstream that had been a coordination challenge in previous projects, removing that complexity from our internal team entirely.
Why did you choose this company over other providers you considered?
We ran a structured shortlisting process across five vendors. The technical evaluation eliminated two immediately. Of the remaining three, this team's proposal was differentiated by the specificity of their DevOps Services approach and the evidence base they provided — reference projects in Government & Public Sector contexts, not generic case studies. The reference calls confirmed a track record that the proposal had described accurately.
How clearly did the company understand your requirements and business goals?
Extremely well, in part because they had relevant Government & Public Sector experience that reduced the context-setting overhead significantly. They understood the domain vocabulary, asked the right questions, and translated business requirements into technical specifications with a fidelity that meant the development phase had very few clarification cycles.
How was your overall experience with their communication and project management?
Professional and efficient. The project manager maintained a clear view of the critical path at all times and communicated changes to it transparently. The one significant scope adjustment we made mid-project was handled through a clean change request process — fairly priced, clearly documented, and absorbed without disrupting the overall timeline.
Did the company deliver the project on time and within your expected budget?
Yes. I had privately built a contingency expectation into my planning given the project complexity and the number of integrations involved. None of that contingency was needed. The delivery landed on the agreed date and the final invoice matched the approved budget to within a fraction of a percent. That outcome is rarer than the industry acknowledges.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is the performance of the system in production. In the five months since go-live we have had zero P1 incidents, our page performance scores have improved across every Core Web Vitals metric, and two enterprise clients who had cited our previous platform limitations during contract negotiations have since renewed without that objection arising.
What did you like most about working with this company?
The willingness to be direct. When our requirements were unclear they said so. When our priorities were contradictory they explained why. When a technical approach we had assumed was the right one turned out to have significant downsides, they told us before we had committed to it. That kind of intellectual honesty is what I look for in a long-term technology partner.
Would you recommend this company to others, and would you work with them again?
Unreservedly. We are in active scoping conversations for a second engagement and I expect this to develop into a multi-year partnership. For any organisation in the Government & Public Sector sector looking for DevOps Services expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.
