2019 Annual Report (^71)
- Used this platform to provide holistic
 training and certification for key software
 roles such as software development
 managers, software engineers, system
 engineers, and product management
 engineers.
- Had more than 9,000 employees pass the
 required certification in 2019.
● Trustworthy processes
- The key to a trustworthy process lies in
 preventing implantation, tampering, and
 backdoors throughout a repeatable and
 traceable process.
- In 2019, we preliminarily built
 trustworthiness into the whole process from
 requirement definition, coding, and build, to
 testing, release, and deployment.
- A total of 62 business domains and
 product lines have participated in this
 transformation.
● Code refactoring
- We created a team culture that is conducive
 to clean code and continuous refactoring,
 optimized the product architecture based
 on trustworthy results, and refactored
 legacy code under this architecture, thereby
 cleaning the code.
● Trustworthy results
The key to achieving trustworthy results
is ensuring both security and resilience,
systematically resolving issues on the
architecture side, and making steady and
gradual progress.- In 2019, we completed threat analysis,
 defined what a trustworthy product is, and
 set external certification goals for all our
 products. All of this informed our software
 architecture improvement.
- Our MA5800 has passed the tier 4
 certification of the National Institute
 of Standards and Technology (NIST)’s
 Cybersecurity Framework (CSF), Euler OS
 of CC EAL4+ certification, and HongMeng
 Kernel of CC EAL5+ certification.
■ Transformation in the Carrier Business

 production processes, allowing for multiple
 parties to manage delivery projects in a
 well-coordinated manner;
- Kept transaction information structured,
 improved the transaction efficiency of both
