Look-back 4: Build v1→v2 Iteration

Sprint 4 · Extra credit · ~25 min · Optional · 5 pts

Sequential

Do Look-backs 1, 2, and 3 first. Look-backs unlock in order.

5 points. ~25 minutes. Build v1 → Build Review → Revised Plan → Build v2 is the cleanest iteration arc in the course. The honest question: what did the iteration actually teach you?

Recovery for points you lost earlier

If you've fallen behind on grades, this is a real path forward.

Each look-back asks you to revisit one piece of Sprint 1–3 work honestly. Complete it, then check-in with Prof. Sathya in class to get credit for your submission — work is reviewed and credited on the spot.

You don't have to do this. It's optional. It's here because the work itself is worth doing — and the points help if you need them.

How this works · Read first

The Look-back workflow — four steps.

  1. Open your existing "Sprint 4 Look-backs" Google Doc. Add a new section titled "Look-back 4 — Build v1→v2 Iteration".
  2. Open all three Sprint 3 documents in new tabs and re-read them as one arc — not separately: Build v1, Build Review, and Revised Plan. The iteration only makes sense as a sequence.
  3. Write your responses to the 6 prompts below, directly in your Look-back doc.
  4. Export as PDF and submit here on Canvas. File → Download → PDF Document. Each submission is the full Look-back doc to date.

The 6 prompts

Step 1 of 6

What surprised you re-reading the three documents as one arc?

Don't read them separately. Read v1 → Review → Revised Plan as a single iteration. What's true on the page that you forgot you'd written?

Step 2 of 6

What was the Build v1→v2 sequence trying to develop in you?

The course doesn't make you build twice for fun. Name the actual capability the iteration sequence was building.

Step 3 of 6

What did you not know going into Build v1?

Specifically. Not "I didn't know everything" — what was the actual gap? What did you assume that turned out to be wrong, or what did you skip because you didn't know it mattered?

Step 4 of 6

What did the Build Review reveal that you didn't already know?

Be honest. Did the review tell you something new, or did it confirm something you'd already started to suspect? The difference matters.

Step 5 of 6

What changed between v1 and v2?

Look at the actual code, the actual design, the actual approach. What's measurably different? "I improved it" doesn't count.

Step 6 of 6

One sentence about how you actually iterate when you don't know the answer.

Across this arc and your other Sprint 3 work. The honest sentence about your iteration habit.
