Liked, Learned, Longed For and Lacked

A retrospective in Scrum is a meeting in which the development team reflects on processes, tools, skills, relationships, challenges and experiences after a sprint. The 4L Retrospective is a variant of this review.

4L stands for:

  • Liked: What did the team really enjoy about the sprint? In particular, what worked better than expected?
  • Learned: What new things did the team learn during the sprint? These can be technical or organizational aspects.
  • Longed For: What things did the team want to have during the sprint that weren’t available? These can also be technical aspects such as additional licenses for a certain software or non-technical aspects such as more regular communication with the product owner.
  • Lacked: What things could the team have done better in the sprint? What was missing in the sprint?

Tips for performing the 4L Retrospective

There are a number of tips for conducting a 4L retrospective:

  • Like all retrospectives, the 4L retrospective should also be conducted using a timebox. The length of the timebox is determined by the size of the team and the duration of the sprint or iteration.
  • After collecting the relevant points, they are grouped, discussed, evaluated and implemented accordingly in the next sprint.
  • Even though the current Scrum Guide 2020, in contrast to its predecessor, no longer actively recommends including the result of the retrospective in the backlog, this is often a sensible measure.

Basically, the 4L Retrospective is easy to set up for the facilitator and easy for the participants to understand. Because of this simplicity, it is popular and frequently used.
