As in the preceding phases, gap analysis and draft architectures are used as a baseline, as are the architecture guiding principles agreed upon in the preliminary phase.

如前面的阶段里，间隙分析和草案架构用作基线，由于初期对架构指导原则达成一致。

The first part of the assignment is to submit in Recitation 9 (1) a preliminary title, (2) a draft outline, and (3) an initial set of references for your end-of-the-term assignment.

请在第21堂课时交报告的第一部份，包括（1）预定的题目，（2）草拟的大纲，（3）和期末报告相关的参考资料。
