LIKED

What did you enjoy?

02

LACKED

What was missing?

03

LEARNED

What did you learn?

The 4Ls — Liked, Learned, Lacked, Longed for — is a reflection-heavy format that treats the sprint as a learning experience rather than just a delivery window. It was designed to answer a question simple formats miss: what did we discover, and what were we missing?

The Lacked column is the quiet star. Teams rarely get asked 'what was missing?' directly, and the answers — missing context, missing tooling, missing decisions — are usually the root causes behind the symptoms other retro formats collect.

When to use Liked · Learned · Lacked

  • End of a project phase, quarter, or milestone — anywhere reflection beats speed
  • After adopting a new technology, process, or team structure
  • When recent retros produced shallow cards and you want more depth
  • Onboarding retrospectives: what did new joiners lack in their first weeks?

How to run it in Retromik

  1. 1

    Create cards anonymously

    Everyone adds cards to each column at the same time. In Retromik, cards stay concealed and anonymous while people write, so nobody anchors on the loudest voice.

  2. 2

    Vote on what matters

    Each person places a limited set of voting tokens on the cards they think deserve discussion. Limited tokens force real prioritization.

  3. 3

    Discuss the top cards

    Walk through the highest-voted cards one by one. The facilitator steers the focus; anyone can comment on any card.

  4. 4

    Reveal and group themes

    Authors are revealed and the facilitator drags related cards into named themes, turning scattered notes into patterns.

  5. 5

    Commit to action items

    Convert the discussion into specific, owned action items with due dates — the part most retrospectives skip.

Frequently asked questions

What does 4Ls stand for in a retrospective?

Liked, Learned, Lacked, and Longed for. The team reflects on what they enjoyed, what they discovered, what was missing, and what they wished they had. Retromik's template uses three columns — Liked, Lacked, Learned — with 'longed for' prompts folded into the Lacked discussion.

How is 4Ls different from Start, Stop, Continue?

Start, Stop, Continue collects behaviour changes; 4Ls collects understanding. 4Ls is better when you need to know why things happened — the learning and the gaps — before deciding what to change. Many teams alternate between the two.

How long does a 4Ls retrospective take?

Plan for 60 minutes with a team of 5-8: the Learned and Lacked columns generate deeper discussion than lightweight formats, so give the discussion phase at least 25-30 minutes.

Can I run a 4Ls retro asynchronously?

Yes. Share the board link and let people add anonymous cards over a day or two, then meet for 30 minutes to vote, discuss the top cards, and commit to actions.
