During which periods is planning done (weekly, bi-weekly sprints)?

Sprint planning usually occurs in periods chosen depending on the team and project. The most common are weekly and bi-weekly sprints:

• Weekly sprints allow for quick adaptation to changes, frequent feedback, and maintaining a high development pace.
• Bi-weekly sprints are a more balanced option, providing enough time for task completion and planning while maintaining flexibility.

Sometimes longer sprints (3-4 weeks) are used, but they are less popular as they reduce feedback frequency and can slow down response to changes. The choice of period depends on the project's specifics, team maturity, and customer requirements.
