CS2113/T: Software Engineering & Object-Oriented Programming

What does mean to 'follow an iterative approach in covering topics'?

It means, we cover a little bit of i.e., requirements, design, testing, project management, ...all SE aspects at first and then iteratively go deeper into them later, revisiting each aspect many time over the course of the semester. In contrast, a sequential approach would have covered one SE aspect before moving to the next (e.g., teach the requirements aspect completely before moving to the design aspect).

The choice of which topics are covered each week is driven by the project i.e., we give priority to topics that you'll need to apply soon in the project that you will be doing in parallel.

This way of 'jumping around' topics feels chaotic but consider the benefits:

• It allows you to start doing SE projects early, and iteratively too. That is, you can start with a small project from the very start and make it bigger progressively, learning from earlier mistakes, and getting multiple chances improve on previous attempts.
• Important SE aspects such as testing can be practiced from the very beginning. If we followed a sequential approach, you an only learn it near the end of the semester.
• Lower risk of missing out some SE aspects altogether. For example, suppose your schedule got heavier in the second half of the semester and you could barely follow the module during that half. You still go away with the basic knowledge of all SE aspects rather than knowing some aspects fully and missing some other aspects altogether.

To help you cope with the non-sequential progression of topics, this module website contains two versions of the topics. In the Schedule page, you'll find the topics organized into the order we cover them in each week. In the Textbook page, you'll find the topics in their natural sequential order. This format is suitable for exam reference.
