BackBuild Loop (The Safety Mechanism)

After:

• Failed tests
• Sprint reviews
• Architecture decisions
• Integration findings

You redraw the end picture and update the map.

The end picture is always provisional. This is very important

Never final.

Never fixed.

This is what makes BackBuild different from waterfall planning:

• The vision adapts
• The sequence adapts
• The team shape adapts

Activities

• Incorporate BackBuild into sprint reviews
• Regular architecture sync
• Weekly design–engineering sync

Frameworks / Tools

• BackBuild update cycle
• Architecture <> Engineering <> Product feedback loop
• Sprint-to-backlog refinement

Outputs

• Continuously updated BackBuild map
• Adjusted sequencing
• Earlier predictions of blockers
• Steadier flow and less rework

Who attends

• Product Lead
• Engineering Lead
• Architect
• Designer

How long

• 10–15 minutes embedded in Sprint Review
  + 15-minute Architecture Sync each fortnight

Notes

This is not a workshop, it is an ongoing rhythm.
