Project delivered with the kind of professionalism that earns a long-term relationship

Piotr Wojciechowski / Head of Development - Vistula Software Sp zoo

Jun 30, 2023

Project summary: Our existing platform had grown organically over several years and the accumulated technical debt was beginning to affect both performance and our ability to ship new features.

I have worked with development agencies on four continents over the past fifteen years and this team sits comfortably in the top tier. What separated them was not just technical skill, which was genuinely impressive, but their instinct for asking the right business questions before reaching for a technical answer. The project ran to schedule, the architecture is clean and well-documented, and the handover was thorough. Six months after go-live we have not raised a single critical support ticket. That speaks for itself.

PROS

Architectural decisions that will serve us for years rather than just solving the immediate problem, knowledge transfer that left our team genuinely capable, no scope creep at all

CONS

The volume of quality documentation they produced was genuinely impressive but also meant our team needed dedicated time to review it properly — a minor process point, not a complaint

Questions & Answers

Please describe your company, your role, and the industry you operate in.
Vistula Software Sp zoo is a Construction business based in Warsaw, Poland. As Head of Development I am responsible for all technology investment decisions, vendor selection, and ensuring our digital capabilities match our growth ambitions. We operate in a competitive market where the quality of our software directly affects our ability to win and retain clients.
What specific problem or business challenge led you to hire this company?
Our existing Industry-Specific Solutions capability had accumulated years of technical debt that was slowing every new feature to a crawl. Incident frequency was rising, developer confidence was falling, and we knew a rebuild was overdue. We needed a partner with the depth to do it properly rather than apply another layer of patches.
What services did the company provide for your project?
The full Industry-Specific Solutions lifecycle from discovery through to production deployment and hypercare support. This included requirements workshops, solution architecture, sprint-based development, QA and automated testing, deployment to our cloud environment, and a structured handover with documentation. They also provided a brief post-launch period of dedicated support which was genuinely useful.
Why did you choose this company over other providers you considered?
Price was a factor but not the deciding one. They were mid-range in our evaluation. What tipped it was the combination of their technical depth in Industry-Specific Solutions, the seniority of the team they proposed to assign to our account, and the clarity of their project governance model. We had been burned by an agency that overpromised before and we needed to see evidence of process maturity.
How clearly did the company understand your requirements and business goals?
Thorough and precise. They translated our business language into technical requirements without losing the intent, which is a skill that sounds straightforward but frequently goes wrong. Every user story they wrote was reviewed against the original business objective before it entered the sprint and the acceptance criteria were specific enough to remove subjectivity from QA.
How was your overall experience with their communication and project management?
Professional and efficient. We used a shared project management tool that gave our stakeholders visibility without requiring them to attend every meeting. The project manager had a clear escalation path and used it appropriately. The only time I needed to intervene directly was when I chose to, not because something had been missed.
Did the company deliver the project on time and within your expected budget?
The project landed on the agreed delivery date and within the approved budget. We did add scope during the engagement — two features that became apparent as essential during user testing — and those were quoted, approved, and delivered without affecting the original scope timeline. That kind of clean change management is not something you can take for granted.
What tangible results or business impact have you seen since the project was completed?
The most direct measure is that the problem we hired them to solve no longer exists. Beyond that, the new Industry-Specific Solutions platform has reduced our operational overhead measurably, our team spends less time managing incidents and more time on product development, and we have been able to onboard two new enterprise clients who had previously cited our technical limitations as a barrier.
What did you like most about working with this company?
The intellectual honesty. They told us when something we wanted was a bad idea and explained why. They told us when a timeline was tight and gave us options. They did not tell us what we wanted to hear in order to win work or avoid a difficult conversation. In a long engagement that kind of relationship is far more valuable than an agency that just says yes.
Would you recommend this company to others, and would you work with them again?
Absolutely. I would recommend them with a specific note that the quality of the discovery process is where the value starts. Clients who invest properly in that phase will get the most out of the engagement. We made that investment and the returns are evident in the quality of what was delivered.
