The walking-skeleton MVP mindset
Imagine this comes up at work: "In your own words, what makes a walking skeleton different from a normal MVP and why does the difference matter to an FDE?" Start with the practical move.
Step 1 of 2
A walking skeleton is a version that touches every stage of the pipeline and does almost nothing well. It's ugly, it's narrow and it's live in days. That's the point.
Most engineers build depth-first: a beautiful transform engine, then weeks later the plumbing to actually run it. An FDE builds breadth-first. You wire input to output through every real step on a single trivial case, prove the path exists, then thicken each stage. A working sliver in three days creates a feedback loop that no design doc can.
Build the perfect core engine first.
Integration left for "later."
Nothing demoable for weeks.
Customer trust erodes while you're heads-down.
One trivial case flows end-to-end on day three.
Every stage exists, none is deep yet.
Customer sees it run on their code immediately.
Each iteration thickens a real, used path.
