fi Speci c Roles

29.

Proxy Product Owner

30.

PPO Encourages Co-creation As a PO I want [WHAT] So that [WHY] This is the reason why the PO want this feature! WHY + WHAT Then this design is good! WHY + WHAT DEV PO PPO QC Excellent suggestions. Great ideas! If that's the reason, this feature is better!

31.

Architect

32.

How is Architect different from Bridge SE?

33.

fi https://blogs.per cient.com/2014/09/23/the-architect-role-in-offshore-development-projects/

34.

The Architect plays the coach role to support the team

35.

Summary( 1/4) •Provide guidance to the team on detail design to ensure that the teamʼs implementation is compliant with the architecture design. He should encourage offshore team members to participate in discussing about the design thus contribute to the architecture.

36.

Summary(2/4) •Listen to the feedbacks from the development team, pick out the good ideas of each side, and help the team see the advantages and disadvantages of each proposed solution then come to a consensus.

37.

Summary(3/4) •Review the code the team submitted fi on daily bases and provide feedbacks to the team. When he nds any coding/ quality issues, provides comments to the team for correction in time (instead of correcting them himself) so that the team can learn and avoid making the same issues in the future tasks.

38.

Summary(4/4) •Help the team to overcome technical fi fi dif culties. This does not mean that architect should take over the dif cult tasks from the team members. He should provide some directions (e.g. sample code, articles, and so on) to support the team to overcome the road blocks.
