keo nha cai cup c1 event was attended by Mr. Bolat Duisenov, Chairman of Coteccons' Board of Directors; Ms. Nguyen Thi Thanh Huong, Human Capital Director; Mr. Doan Hai Nam, CEO of VSOL; Mr. Spencer Lin, Head of Workday Consulting at Rolling Arrays; and Coteccons employees attending both online and in person.

"To go far, you must find keo nha cai cup c1 balance between systems and people"

Speaking at keo nha cai cup c1 "Go-Live Workday" ceremony, Mr. Bolat Duisenov, Chairman of Coteccons' Board of Directors, said that sustainable development requires a business to rely not solely on people or on systems, but to find keo nha cai cup c1 balance between keo nha cai cup c1 two.

He said this is also how Coteccons answers three major questions on its development journey.

• First, how can Coteccons always be keo nha cai cup c1 client's next choice — not only completing a client's first project, but being entrusted with a second, a third, and more?
• Second, how can Coteccons become keo nha cai cup c1 choice of talent? Every day, keo nha cai cup c1 company must create an environment where people want to contribute, want to create value, and are proud to say they work at Coteccons.
• Third, how can Coteccons diversify its sources of growth to build a foundation for sustainable development in keo nha cai cup c1 future?

According to Mr. Bolat, whether discussing clients, talent, or growth, keo nha cai cup c1 starting point is always people.

"Why do we come to work? Coteccons is a people-centered company. But we are all human — we all have strengths, weaknesses, and our own biases. Relying on trust between individuals alone is not enough."

He noted that projects typically last 24–36 months, during which engineers live, work, and share countless experiences together on site. However, for keo nha cai cup c1 business to grow sustainably, it cannot operate on personal relationships alone — it needs keo nha cai cup c1 support of a transparent, well-defined system and process.

"This is a question we have been asking ourselves for years. Today, keo nha cai cup c1 official rollout of keo nha cai cup c1 Workday platform is one of our answers. This is not just a tool for keo nha cai cup c1 HR or administrative departments — it's a platform that helps solve challenges across keo nha cai cup c1 entire organization, benefiting everyone in keo nha cai cup c1 company."

However, Mr. Bolat stressed that adopting a new system does not mean change at any cost.

Every new process brings both opportunities and challenges. "What matters is not changing keo nha cai cup c1 system at any cost, but finding keo nha cai cup c1 balance between system and people. Only when we find that balance can Coteccons truly become an environment where talent can thrive."

What is Workday, and how will it change keo nha cai cup c1 way more than 4,000 Coteccons employees work?

Ahead of "Go-Live Workday," many Coteccons staff wondered: Is Workday easy to use? Will this platform really make a difference in day-to-day work?

According to project representatives, keo nha cai cup c1 answer will come from each employee's own experience once keo nha cai cup c1 system is officially in operation.

With an intuitive interface, Workday is designed as a centralized HR management platform that connects all people and organizational data on a single system. Employees can access it via website or mobile app using their company email account to track HR-related tasks, receive task notifications, apply for leave, and carry out various other HR functions.

But Workday's greatest value lies not simply in digitizing HR processes. Once HR data is standardized and updated in real time, keo nha cai cup c1 company can manage its workforce on a single platform across every project and every market.

For each employee, Workday also opens up a new way of working: proactively accessing information, managing one's own career journey, and connecting with keo nha cai cup c1 entire organization on one platform.

This is not merely keo nha cai cup c1 rollout of a software system — it is a step in Coteccons' long-term transformation roadmap to strengthen organizational capability, support keo nha cai cup c1 "Go Global" strategy, develop "Build Tech" capabilities, and realize keo nha cai cup c1 Human-Hearted Company vision, a culture centered on people.

keo nha cai cup c1 Workday rollout is also one of keo nha cai cup c1 pillars supporting Coteccons' FY2027 theme: "Discipline — From Growth to Quality Growth."

"Go-Live Workday" is just keo nha cai cup c1 beginning: keo nha cai cup c1 biggest challenge is changing management mindset

Following keo nha cai cup c1 platform walkthrough, keo nha cai cup c1 "Go-Live Workday" event continued with a panel discussion centered on one recurring message: Workday is not simply software — it represents a shift in how Coteccons manages its human resources.

keo nha cai cup c1 Workday rollout also marks Coteccons' transition from traditional management to data-driven management. But "Go-Live Workday" is only keo nha cai cup c1 starting point. What lies ahead for Coteccons after this milestone? Will keo nha cai cup c1 greatest challenge be technology, or a shift in people's mindset and behavior?

keo nha cai cup c1 Q&A session featured Ms. Nguyen Thi Thanh Huong, Human Capital Director at Coteccons; Mr. Doan Hai Nam, CEO of VSOL; and Mr. Spencer Lin, Head of Workday Consulting at Rolling Arrays.

Below are keo nha cai cup c1 key points from keo nha cai cup c1 discussion:

Why did Coteccons choose Workday?

According to Ms. Nguyen Thi Thanh Huong, keo nha cai cup c1 first question Chairman Bolat asked at keo nha cai cup c1 start of keo nha cai cup c1 project was simple: "Why do we need Workday?"

Ms. Huong said keo nha cai cup c1 answer lies in Coteccons' growth rate.

"In roughly two years, keo nha cai cup c1 company's scale has nearly doubled. Coteccons now has more than 4,000 engineers, and that number will keep growing in keo nha cai cup c1 years ahead. To grow sustainably, everyone from management to staff needs to work from keo nha cai cup c1 same data source, understand keo nha cai cup c1 same HR processes, and execute with discipline."

Workday was chosen because it is designed with user experience at its core, featuring an intuitive, user-friendly interface that allows employees to quickly get up to speed after training sessions.

From keo nha cai cup c1 implementation partner's perspective, Mr. Spencer Lin, Head of Workday Consulting at Rolling Arrays, said that if he had to describe keo nha cai cup c1 Coteccons project team in one word, he would choose "Agility."

He said what impressed him most was keo nha cai cup c1 team's ability to adapt quickly, combined with a constant focus on keo nha cai cup c1 end goal: helping keo nha cai cup c1 business operate faster and more efficiently.

4 months of implementation: Conquering KPIs through "Own It" and "One Team" spirit

Behind keo nha cai cup c1 "Go-Live Workday" milestone lies a four-month journey that several project members described as a "sprint." According to Mr. Doan Hai Nam, CEO of VSOL (a Coteccons Group member company), keo nha cai cup c1 project team proposed delaying keo nha cai cup c1 timeline three separate times during implementation.

keo nha cai cup c1 workload was enormous, and keo nha cai cup c1 four-month deadline was widely seen as nearly unfeasible — not just for Coteccons, but by market standards, where Workday projects typically take at least a year.

Even so, driven by keo nha cai cup c1 "Own It" spirit and a shared sense of commitment, keo nha cai cup c1 team decided to push forward and completed keo nha cai cup c1 project on schedule.

According to Ms. Nguyen Thi Thanh Huong, that decision clearly reflects Coteccons' "Own It" culture — getting things done no matter what. Once leadership committed that Workday had to go live at keo nha cai cup c1 very start of FY2027 in order to set up keo nha cai cup c1 new KPI system in time, every team member treated that goal as their own personal responsibility, rather than something belonging solely to HR or IT.

At times, project teams held back-to-back meetings, reviewing processes and fine-tuning every detail to stay on schedule. "Chị Hương, could you spare just an hour or two to review this process for me?" were keo nha cai cup c1 kinds of calls that came in regularly throughout keo nha cai cup c1 four months.

If"Own It" reflects each individual's commitment to seeing keo nha cai cup c1 goal through, "One Team" was keo nha cai cup c1 force that carried keo nha cai cup c1 project to keo nha cai cup c1 finish line. According to Ms. Huong, keo nha cai cup c1 Human Capital department, IT, VSOL, and partner Rolling Arrays stopped operating as separate units and instead functioned as one unified team. This was also keo nha cai cup c1 strongest impression left on Mr. Spencer Lin.

"There was a spirit of collaboration running through everyone involved. We had many productive conversations and discussions, all aimed at one shared goal — making Coteccons' business and operational performance as strong and as fast as possible," Mr. Spencer shared. He also praised keo nha cai cup c1 Coteccons team for its ability to adapt quickly, make decisive calls, and coordinate effectively throughout keo nha cai cup c1 implementation.

That spirit also showed up in decisions that went beyond convention. According to Mr. Doan Hai Nam, one of keo nha cai cup c1 biggest challenges in deploying global HR management systems in Vietnam is payroll calculation. VSOL made what he called a "crazy decision": to proactively build a Payroll module and integrate it into keo nha cai cup c1 Workday system, digitizing keo nha cai cup c1 entire payroll process.

As a result, in roughly four months, Coteccons completed "Go-Live Workday" on schedule. According to Mr. Nam, Coteccons' speed has set a "new norm"for keo nha cai cup c1 industry.

After "Go-Live Workday," keo nha cai cup c1 biggest challenge is changing management mindset

According to Ms. Nguyen Thi Thanh Huong, "Go-Live Workday" is not keo nha cai cup c1 destination — it's only keo nha cai cup c1 starting point.

Coteccons' goal is not just to launch a new system, but to change how keo nha cai cup c1 company manages people.

Workday will help every employee understand their position, keo nha cai cup c1 standards for each level, and what they need to develop to advance to keo nha cai cup c1 next role. Meanwhile, managers will have full access to data for more transparent analysis, evaluation, and team development.

Mr. Spencer Lin agreed, adding that keo nha cai cup c1 clearest changes will emerge after 3–6 months, once Workday becomes keo nha cai cup c1 unified platform for tracking goals, evaluating progress, and developing keo nha cai cup c1 capabilities of both individuals and keo nha cai cup c1 organization as a whole.

Asked about keo nha cai cup c1 challenges ahead after "Go-Live Workday," Ms. Huong said keo nha cai cup c1 biggest challenge would no longer be technology.

"keo nha cai cup c1 next challenge is change management. In keo nha cai cup c1 past, we were used to working manually. From now on, we need to change our mindset and shift toward data-driven management instead of relying on gut feeling."

Closing keo nha cai cup c1 discussion, she shared a final message: "Today is only keo nha cai cup c1 beginning." A system is only as good as keo nha cai cup c1 value people create by using it. "I hope Workday will help us understand our people better, manage our human resources more effectively, and contribute together to sustainable, people-centered development."

At keo nha cai cup c1 event, organizers announced a notable milestone: more than 2,000 successful app downloads and logins to Workday within keo nha cai cup c1 first hour of "Go-Live Workday."

This is more than just a statistic — it's evidence of keo nha cai cup c1 Coteccons team's readiness on its journey to build a more connected, more transparent, and more efficient organization.

Going forward, keo nha cai cup c1 project team will continue tracking system usage, with keo nha cai cup c1 goal of having 100% of Coteccons staff fully adopt Workday as keo nha cai cup c1 company's unified management platform.

Following "Go-Live Workday," Coteccons will continue rolling out Workday group-wide in two phases:

• Phase 1B — six months, adding advanced modules to optimize resources, including training, recruitment, in-depth management, workforce planning, data analytics, an employee listening tool (Peakon), and payroll system integration.
• Phase 2 — more than three months, completing keo nha cai cup c1 HR management system for member companies within keo nha cai cup c1 group and bringing Coteccons onto one unified HR management system.

More than "Go-Live Workday" — Coteccons begins a long-term partnership journey

keo nha cai cup c1 "Go-Live Workday" event closed with a gift exchange between Coteccons, Workday, and Rolling Arrays — a token of appreciation for keo nha cai cup c1 months of partnership throughout keo nha cai cup c1 digital transformation project.

Representing Coteccons, Ms. Nguyen Trinh Thuy Trang, Deputy CEO of Operations, and Mr. Doan Hai Nam, CEO of VSOL, presented both partners with keo nha cai cup c1 painting "Purple Flower Field" by artist To Ngoc.

According to keo nha cai cup c1 organizers, keo nha cai cup c1 painting is a sincere thank-you to Workday and Rolling Arrays for their dedication and effort throughout keo nha cai cup c1 project, as well as a wish for keo nha cai cup c1 continued strength of keo nha cai cup c1 partnership and future milestones to come.

In return, representatives from Workday and Rolling Arrays presented Coteccons with keo nha cai cup c1 painting "Ha Long Bay," depicting sails catching keo nha cai cup c1 wind as they head out to open sea.

keo nha cai cup c1 gift carries a message of trust, partnership, and keo nha cai cup c1 aspiration to go further. According to both partners, digital transformation is not a journey for a single company or technology provider to undertake alone — it can only succeed when built on a foundation of sustainable collaboration and shared long-term goals.

Workday has officially gone live, but for Coteccons, this is only keo nha cai cup c1 beginning of a longer journey — one toward building a modern, transparent, people-centered organization.

Throughout this journey, employees will continue to receive support through multiple channels, including guides, training videos, and training courses.
