Shift from Full Systems to Standalone Value Slices

Designers instinctively zoom out to map entire ecosystems of interactions, ensuring cohesive long-term experiences. This prevents fragmentation but clashes with agile, where teams build and release one small piece per sprint. Instead of the full solution, deliver a self-contained slice that stands alone and provides real value now. This feels incomplete and risky compared to comprehensive designs, but it unlocks rapid iteration based on user feedback.

Avoid Horizontal Slicing's Useless Layers

Dividing work by technical layers—like building search algorithms before job listings—creates impressive backend without user-facing value. With no content to search, testing fails, and releases teach nothing. Laura Klein calls this horizontal slicing: it prioritizes infrastructure over complete user flows, yielding impractical prototypes.

Craft Smallest Useful Slice for Quick Insights

Ask: 'What’s the minimal version delivering real value?' For a job search feature, start with a simple listings page showing key details and a basic 'Apply' button (email link or CV upload form). Skip advanced filters, comparisons, or full applications initially. This lets users discover jobs and act, revealing surprises like unexpected details users want or filtering needs. Vertical slices test assumptions early, adapting the product faster than perfecting a grand vision.
