ERP implementation that went live on schedule — rare in this category and we know it

Kenji Watanabe / General Manager, IT - Tokai Digital KK

Oct 05, 2023

Project summary: Our growth into new markets required a multi-currency, multi-language commerce platform that our previous vendor had promised but never delivered.

The technical quality of the work is the easiest thing to praise, but what I want to highlight is the communication culture on this team. Every question got a same-day response. Every risk got flagged before it became an issue. When we needed to change direction mid-project — a business decision on our side — they absorbed the change professionally, requoted fairly, and kept momentum going. That flexibility is something you cannot assess in a proposal and it turned out to be one of the most valuable things about working with them.

PROS

Domain knowledge that went beyond generic expertise into our specific industry, willingness to push back constructively, automated test coverage that gave us deployment confidence

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.

Tokai Digital KK is a Retail & E-commerce business based in Tokyo, Japan. As General Manager, IT 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?

The immediate trigger was a performance failure during our peak trading period that cost us measurably in both revenue and client trust. The root cause was architectural and our internal team did not have the ERP Development expertise to address it properly. We needed specialists.

What services did the company provide for your project?

End-to-end ERP Development delivery with a particular emphasis on the integration layer that connected the new build to our existing Retail & E-commerce infrastructure. They also provided UI/UX input that was not in the original scope but which they offered proactively because they could see it would affect adoption. That kind of initiative was characteristic of how they approached the whole engagement.

Why did you choose this company over other providers you considered?

We evaluated four vendors in total. Two were eliminated after the technical assessment stage because their proposed architectures showed a surface-level understanding of what we needed. This team's proposal demonstrated genuine depth in ERP Development and specific knowledge of the Retail & E-commerce sector that the others could not match. The reference calls confirmed a consistent pattern of delivery.

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?

Communication was handled primarily asynchronously given the time zone difference between Tokyo, Japan and the team's base, but it was managed so well that the gap rarely felt like a constraint. Written updates were clear and timely, escalations were handled promptly, and we never had to chase for a status update. The cadence was exactly right — enough to feel informed, not so much that it created overhead.

Did the company deliver the project on time and within your expected budget?

On time and within the agreed budget. They had given us a range estimate at the start, which I had been sceptical of, and they landed within the lower half of that range. Their estimation accuracy came from having broken the work down in genuine detail during discovery rather than giving a rough number and hoping. It showed in every sprint.

What tangible results or business impact have you seen since the project was completed?

Hard to isolate precisely because several factors changed simultaneously, but the data we can attribute directly to the new ERP Development platform shows a meaningful improvement in the metrics that matter to our Retail & E-commerce business. Our account managers report that the new capability is coming up positively in client conversations, which was one of the strategic objectives we started with.

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.

CI/CD pipeline that turned our two-week releases into same-day deployments

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.

Project governance was one of the things that impressed me most. We had a dedicated project manager who ran tight fortnightly sprints with clear acceptance criteria, a shared backlog that gave us full visibility at all times, and a change request process that was fair and transparent. Nothing slipped through the cracks, no bill shock at the end, and the final delivery matched the original scope document almost perfectly. In my experience that kind of discipline is genuinely uncommon.

PROS

Business-aware approach to every technical decision, strong project governance, fast turnaround on feedback, zero drama during a genuinely complex engagement

CONS

The initial project brief document they required was more detailed than we were used to providing, but in hindsight that rigour was part of why the project ran so smoothly

Questions & Answers

Please describe your company, your role, and the industry you operate in.

As Head of Product Development at Sunrise Commerce KK, I manage a cross-functional technology team serving our Events & Event Management clients from Osaka, Japan. We are a commercially focused organisation and every technology decision we make is evaluated against a clear business case. We needed a partner who understood that context, not just the technical brief.

What specific problem or business challenge led you to hire this company?

The immediate trigger was a performance failure during our peak trading period that cost us measurably in both revenue and client trust. The root cause was architectural and our internal team did not have the DevOps Services expertise to address it properly. We needed specialists.

What services did the company provide for your project?

Primarily DevOps Services, though the scope naturally touched adjacent areas. They handled architecture design, implementation, integration with our existing systems, performance testing under realistic load, and knowledge transfer to our internal team. The breadth of what they covered without requiring us to bring in additional vendors was one of the reasons the project ran efficiently.

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 DevOps Services, 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?

The requirements understanding was solid from early on, aided by the fact that they had prior experience in the Events & Event Management sector and did not need us to explain domain context that a less experienced team would have required. That background knowledge shortened the discovery phase meaningfully and reduced the volume of clarification questions during sprints.

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 DevOps Services 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?

Their ability to hold the business objective in mind alongside the technical task. I have worked with technically excellent agencies who lost the thread of what we were actually trying to achieve. This team never did. Every architectural decision, every trade-off conversation, every prioritisation discussion was anchored to the outcome we had agreed at the start.

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.
