Publishing workflow that took our time-to-live from days to under an hour

Flynn Buchanan / GM of Technology - Pacific Rim Commerce Group

Verified
Mar 17, 2026

Project summary: Our engineering capacity was committed to maintaining existing systems and could not absorb a net-new build of this complexity. An external partner with the right skills was the only viable option.

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

Commercially transparent throughout — no hidden assumptions, no bill shock at the end, change requests that were fair and clearly explained rather than used as a margin-recovery mechanism

CONS

Their discovery process is more rigorous than we were accustomed to and required more preparation from our side than we had initially allocated — but the quality of what followed justified every hour of it

Questions & Answers

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

Pacific Rim Commerce Group is an established Human Resources organisation headquartered in Perth, Australia. My role as GM of Technology 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 CMS Development 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?

End-to-end CMS Development delivery with particular depth in the integration and data migration components, which were the highest-risk elements of the programme. They supplemented this with a dedicated QA resource throughout development and a documented runbook for our operations team at handover.

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?

The project management framework was the most structured I have experienced with an external vendor. Sprint planning was tight, acceptance criteria were specific, retrospectives were honest and acted on. The project manager treated the shared backlog as a live document and the risk register as an operational tool rather than a compliance artefact. I never had to ask for a status update.

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 ROI case we presented to our board was conservative by design. Current performance against the financial model suggests we will hit the projected payback point in under twelve months against an eighteen-month target. The operational efficiency gains in particular have exceeded the model, in part because the quality of the data the new platform generates supports decisions that the previous system could not.

What did you like most about working with this company?

The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.

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 Human Resources sector looking for CMS Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Multiplayer infrastructure that held through a launch-day traffic spike we had not fully anticipated

Project summary: Digital service standards required all citizen-facing applications to meet accessibility and performance benchmarks that our inherited systems failed. Remediation was not viable — we needed a replacement.

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

Production system that has performed as specified since go-live without remediation work, documentation thorough enough to support internal maintenance, knowledge transfer that left our team genuinely capable

CONS

We underestimated the input required from our subject matter experts during the requirements phase. The team flagged this early but our resource planning did not fully reflect it — our responsibility, not theirs

Questions & Answers

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

I lead technology at Emerald Digital Ltd, a growth-stage Government & Public Sector business based in Dublin, UK. As VP of Product Engineering 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?

The immediate problem was that our Game Development capability had become the bottleneck limiting our ability to grow. Every feature request, every new client requirement, every internal initiative was delayed by a platform that had been extended beyond its original design. We needed a rebuild, not a patch.

What services did the company provide for your project?

Primarily Game Development, 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?

Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between Dublin, UK and the delivery team. Written updates were specific and consistent, response times were same-day for anything that required a decision, and nothing fell through the cracks across a six-month engagement.

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

Yes to both. There was a single sprint where a dependency on a third-party API introduced a one-week delay. The team identified it three weeks in advance, presented two mitigation options, and we agreed on an approach that recovered the schedule within the same sprint cycle. That level of foresight is what separates good project management from reactive problem management.

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

Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the Game Development work are meaningful: session duration up, conversion rate up, error rate down, and our NPS for the digital touchpoint has improved by eleven points. Our account managers report that the new capability is coming up positively in client conversations.

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 Government & Public Sector sector looking for Game Development expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.

Virtual environment that our remote team now uses as their primary collaboration space

Adriana Voss / Director of Platform Engineering - Cascadia Digital Ventures

Feb 26, 2026

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.

Six months after go-live our platform is processing three times the transaction volume we specified in the original brief. The architecture choices made during discovery accommodated that growth without remediation work. That is the difference between a team that designs for what you tell them and a team that designs for what you are likely to need. We are in conversation about a Phase 2 engagement and I expect to be using this partnership for several years.

PROS

Commercially transparent throughout — no hidden assumptions, no bill shock at the end, change requests that were fair and clearly explained rather than used as a margin-recovery mechanism

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

Project Cost$500,000+

DurationMay 2025 – Jan 2026

Questions & Answers

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

Cascadia Digital Ventures operates in the Government & Public Sector sector with headquarters in Vancouver, Canada. In my role as Director of Platform Engineering I am accountable for the full technology agenda — infrastructure, product, and vendor relationships. We are a commercially driven organisation and every technology decision is evaluated against a clear business case before it is approved.

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

We had a defined product vision for our next phase of growth in the Government & Public Sector market but lacked the engineering depth internally to execute it. The AR/VR Development requirements in particular required specialist experience that we could not realistically recruit for on the timeline our business plan required.

What services did the company provide for your project?

End-to-end AR/VR Development delivery with particular depth in the integration and data migration components, which were the highest-risk elements of the programme. They supplemented this with a dedicated QA resource throughout development and a documented runbook for our operations team at handover.

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 AR/VR Development 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?

Comprehensively. The discovery phase they ran was more thorough than anything we had experienced with previous vendors. They challenged requirements that were vague or contradictory, proposed alternatives where our initial thinking was limiting, and produced a functional specification that our internal stakeholders agreed was the clearest articulation of the product they had seen written down.

How was your overall experience with their communication and project management?

Outstanding. The discipline around asynchronous communication was particularly effective given the time zones involved between Vancouver, Canada and the delivery team. Written updates were specific and consistent, response times were same-day for anything that required a decision, and nothing fell through the cracks across a six-month engagement.

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?

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?

The post-launch behaviour. Some vendors consider go-live to be the end of their professional obligation. This team treated it as the transition to a different kind of engagement. The hypercare period was substantive, the documentation was thorough and genuinely useful, and they checked in proactively at the thirty-day and ninety-day marks to review production metrics with us.

Would you recommend this company to others, and would you work with them again?

Yes, without reservation. I have already made two direct referrals within my Government & Public Sector network — in both cases to peers facing AR/VR Development challenges similar to ours. I gave those referrals with confidence because I knew the experience I described was reproducible, not the result of exceptional circumstances on our engagement.

Automation that freed our team from repetitive analysis and let them focus on strategy

Project summary: Warehouse management inefficiencies were adding cost and introducing errors at a rate that was becoming visible to clients. A modernised WMS was the agreed solution internally — we needed a partner to build it.

The technical quality of the final deliverable is the easiest thing to point to. The automated test coverage is thorough, the deployment pipeline is reliable, the documentation is genuinely useful rather than ceremonially produced. But the metric I keep returning to is the number of post-launch conversations we have not had to have. No incident calls at two in the morning. No emergency patches. No retrospective discussions about what went wrong. The absence of those events is the evidence I would show to someone considering this vendor.

PROS

Production system that has performed as specified since go-live without remediation work, documentation thorough enough to support internal maintenance, knowledge transfer that left our team genuinely capable

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.

I lead technology at Wisła Software Sp zoo, a growth-stage Logistics & Supply Chain business based in Warsaw, Poland. As Head of Development 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?

We had a defined product vision for our next phase of growth in the Logistics & Supply Chain market but lacked the engineering depth internally to execute it. The AI & Machine Learning requirements in particular required specialist experience that we could not realistically recruit for on the timeline our business plan required.

What services did the company provide for your project?

Primarily AI & Machine Learning, 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?

Better than we managed ourselves going in. The workshops they facilitated surfaced assumptions we had not examined and exposed three requirements that were in direct conflict with each other. Resolving those before development began saved us what would certainly have been significant rework later in the project.

How was your overall experience with their communication and project management?

The project management framework was the most structured I have experienced with an external vendor. Sprint planning was tight, acceptance criteria were specific, retrospectives were honest and acted on. The project manager treated the shared backlog as a live document and the risk register as an operational tool rather than a compliance artefact. I never had to ask for a status update.

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

The project landed on time. The budget was managed within the agreed ceiling, which included one client-driven scope addition that was quoted fairly and handled without affecting the original delivery stream. The discipline around budget transparency throughout meant there was no surprise at invoice stage.

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

The ROI case we presented to our board was conservative by design. Current performance against the financial model suggests we will hit the projected payback point in under twelve months against an eighteen-month target. The operational efficiency gains in particular have exceeded the model, in part because the quality of the data the new platform generates supports decisions that the previous system could not.

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 Logistics & Supply Chain sector looking for AI & Machine Learning expertise combined with genuine delivery discipline, I would put this team at the top of the evaluation list.
