Scrum is hard for Vietnamese

" Team be self-organizing and self-led":
Đây là yêu cầu khó, đòi hỏi kinh nghiệm, tuổi tác và sự chuyên nghiệp.
Ở VN build 1 team như vậy khá khó (tìm) và cũng tốn tiền của tuyển
dụng, giữ chân.

Core Scrum roles

The core roles in Scrum teams are those committed to the project in
the Scrum process—they are the ones producing the product (objective
of the project).

Product Owner
The Product Owner represents the voice of the customer and is
accountable for ensuring that the Team delivers value to the business.
The Product Owner writes customer-centric items (typically user
stories), prioritizes them, and adds them to the product backlog.
Scrum teams should have one Product Owner, and while they may also be
a member of the Development Team, it is recommended that this role not
be combined with that of ScrumMaster.[11]

Team
The Team is responsible for delivering the product. A Team is
typically made up of 5–9 people with cross-functional skills who do
the actual work (analyse, design, develop, test, technical
communication, document, etc.). It is recommended that the Team be
self-organizing and self-led, but often work with some form of project
or team management.

ScrumMaster
Scrum is facilitated by a ScrumMaster, also written as Scrum
Master, who is accountable for removing impediments to the ability of
the team to deliver the sprint goal/deliverables. The ScrumMaster is
not the team leader but acts as a buffer between the team and any
distracting influences. The ScrumMaster ensures that the Scrum process
is used as intended. The ScrumMaster is the enforcer of rules. A key
part of the ScrumMaster's role is to protect the team and keep them
focused on the tasks at hand. The role has also been referred to as
servant-leader to reinforce these dual perspectives.
