In November 2025, DEHA Vietnam proudly achieved the CMMI Development & Service Level 3 certification. This milestone demonstrates that the organization has reached the “Defined” maturity level for both development and service operations. In other words, DEHA’s processes are clearly defined, standardized, and consistently implemented across the organization. This maturity level reflects a strong foundation for quality and consistency, supported by well-established, documented, and continuously improved processes.

Key Characteristics of CMMI Development & Service Level 3

• Defined Processes:
  The organization maintains a standardized and documented set of processes for both software development and service delivery, ensuring consistent execution across all projects and operations.
• Standardization:
  Standard processes are continuously reviewed and improved over time, while project teams tailor these standards according to organizational guidelines.
• Project and Service Management:
  Structured project and service management practices are applied, incorporating industry best practices such as risk management, configuration management, quality assurance, and verification & validation.
• Organizational Support:
  The organization proactively establishes operational processes, provides necessary training, and focuses on continuous improvement at the organizational level.
• Consistency Across Operations:
  Processes are integrated into a cohesive system that is clearly understood and consistently applied across all projects and services.

Back in 2022, DEHA successfully achieved the CMMI Development Level 3.0 certification, which helped standardize and stabilize the company’s software development activities. However, by 2026, DEHA’s business model had evolved significantly — expanding from project-based development to long-term service operations, with increasing demands for support services, maintenance, SLA management, and post-deployment operations. These areas were not fully covered by the original CMMI Development framework alone.

To achieve the CMMI Development & Service Level 3.0 certification, DEHA launched a comprehensive transformation program that went beyond process improvement to include operational and management transformation, preparing the company for its next stage of growth.

First, DEHA reviewed and redesigned its entire workflow — from software development to service operations — ensuring processes were standardized while still remaining practical and aligned with real business needs.

At the same time, the company introduced a data-driven management approach into daily operations, covering planning, quality tracking, SLA management, and risk control. DEHA also invested heavily in people development through training programs, clearer role definitions, and enhanced project and service management capabilities.

Most importantly, this achievement was driven by strong commitment from leadership. At DEHA, CMMI is not viewed simply as a certification target, but as a long-term operational foundation for stability, scalability, and sustainable growth.

Through achieving CMMI Development & Service Level 3.0, DEHA delivers greater value and peace of mind to customers through three key pillars:

• Organization-wide process standardization, ensuring quality and project delivery are consistently controlled without depending on individual performance.
• Proactive risk and change management, allowing issues to be identified and resolved early before impacting customers.
• Continuous measurement and improvement mechanisms, helping services evolve and improve every day.

As a result, customers not only receive products that meet their requirements, but also experience stability, transparency, and reliability throughout the entire partnership journey.
