+# Retrospective
+
+## Stop Doing
+
+* Scheduling meetings without ensuring the time works for everyone.
+
+* Delaying the first meeting too close to the submission deadline.
+
+## Continue Doing
+
+* Communicating regularly and clearly through Slack.
+
+* Dividing tasks fand assigning responsibilities.
+
+## Start Doing
+
+* Scheduling meetings earlier in the milestone to allow more preparation time.
+* Using shared tools to coordinate availability (e.g., shared calendar, polling tools).
+
+## Lessons Learned
+
+* Time coordination is just as important as task division—having a great
+  plan doesn't help if no one can meet to align on it.
+
+* Our communication and teamwork were strong, which helped
+  us get back on track even with a late start.
+
+* Flexibility and understanding among team members are
+  essential for navigating scheduling conflicts.

+## Strategy vs. Board
+
+### What parts of your plan went as expected?
+
+* Communication tools worked well and helped us stay connected
+
+### What parts of your plan did not work out?
+
+* Our first meeting was delayed and happened very close to the deadline.
+
+### Did you need to add things that weren't in your strategy?
+
+### Or remove extra steps?
