End-to-end quality programme that halved our post-release incident rate inside three months

Hyun-Su Lim / Director of Platform - Hanam Tech Solutions

Jan 13, 2026

Project summary: Dynamic pricing had been a manual process for years. We knew the revenue management opportunity was significant but lacked the technical capability to build the models and connect them to our booking engine.

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

Senior-level engineering presence throughout the entire project, not just during the pitch, honest and commercially fair handling of scope changes, codebase that our internal team praised on review

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.
As Director of Platform at Hanam Tech Solutions I oversee technology investment and delivery across our Travel & Hospitality operations in Incheon, South Korea. We are a commercially focused business and our technology choices are always evaluated in terms of their direct contribution to business outcomes rather than technical elegance alone.
What specific problem or business challenge led you to hire this company?
Regulatory requirements in our Travel & Hospitality segment had changed and the compliance timeline was set by our regulator, not by us. The Quality Assurance & Testing 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 Quality Assurance & Testing 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 had a failed engagement behind us and were more rigorous in our selection process as a result. We asked detailed questions about how they managed scope change, how they handled estimation, and how they communicated problems. The answers were specific, evidenced, and consistent across the team members we spoke to. That gave us confidence that the process was real rather than rehearsed.
How clearly did the company understand your requirements and business goals?
Extremely well, in part because they had relevant Travel & Hospitality 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?
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?
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?
Quantifying the impact precisely is complicated by other variables in our business, but the metrics we can attribute directly to the Quality Assurance & Testing 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?
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?
Absolutely. With a specific note that the value starts in the discovery phase — clients who approach that process with seriousness will get the most from the engagement. We invested appropriately at the front end and the returns are evident in what was delivered.

FAQs

Will Sierra Experts sign an NDA before we even discuss the project in detail?

What makes Sierra Experts worth considering over other options?
What tends to set Sierra Experts apart usually comes down to some mix of technical depth, relevant industry experience, how clients describe working with them, their development approach, communication habits, and whether they can actually deliver something that scales. Founded in 2003, the company has built a track record of delivering projects across various industries.
What kind of software work does Sierra Experts take on?
Sierra Experts typically covers the standard range of software development work — mobile apps, web platforms, custom internal tools, UI/UX design, cloud infrastructure, AI integrations, and larger enterprise builds. Its core focus areas include Custom Application Development, Custom Software Development, Mobile App Development, UI-UX Design and Web Design.
Can I just hire developers from Sierra Experts to sit alongside my own team?
Usually, yes — a dedicated developer arrangement is a common option with firms like Sierra Experts, where you get engineers working exclusively on your project as an extension of your in-house team rather than as a separate outsourced unit. For context, its listed capabilities span Custom Application Development, Custom Software Development, Mobile App Development, UI-UX Design and Web Design, and its average project cost is reported at $2500000+.
Is Sierra Experts more of an offshore setup or a local team?
That depends on where Sierra Experts is based and who they primarily serve — some firms like this operate fully offshore, some are local-first, and plenty run a hybrid model that mixes both. For context, it has experience across industries such as Insurance, Travel & Hospitality, Logistics & Supply Chain, Manufacturing and Nonprofit & NGO, and its typical hourly rate is around N/A.
Can Sierra Experts take on an old, outdated system rather than starting from scratch?
Modernizing legacy software is usually within scope for a firm like Sierra Experts — re-platforming, refactoring old code, and moving things onto current frameworks or cloud infrastructure without necessarily rebuilding everything from zero. For context, it has served clients in USA, and its listed capabilities span Custom Application Development, Custom Software Development, Mobile App Development, UI-UX Design and Web Design.
How do I actually get a real proposal out of Sierra Experts instead of a generic reply?
The most reliable route is giving Sierra Experts a clear, specific brief up front — through their website form, a direct email, or a call — since a vague ask tends to get a vague answer back, while a concrete one usually gets a proper estimate. For context, it has served clients in USA, and it has experience across industries such as Insurance, Travel & Hospitality, Logistics & Supply Chain, Manufacturing and Nonprofit & NGO.
Has Sierra Experts actually shipped a SaaS product before?
It's a common line of work for a company like Sierra Experts — multi-tenant architecture, subscription billing hooked up properly, and cloud-native deployment built for a product meant to scale as a service rather than a one-off build. For context, its listed capabilities span Custom Application Development, Custom Software Development, Mobile App Development, UI-UX Design and Web Design, and it has been operating since 2003.
What should I expect to pay to work with Sierra Experts?
What Sierra Experts charges comes down to a handful of variables — how complex the project is, the number of development hours involved, the tech stack required, team size, and which engagement model you pick. Based on available data, Sierra Experts's typical hourly rate is around N/A, with an average project cost of $2500000+.
