Compare and Contrast – A Technique for Better Specs

SUMMARY

By providing compare and contrast opportunities in our specs, we are infusing ux into the ux/ui hand-off experience.

When we are in the process of providing specs for a product enhancement, the developers are already familiar with the product (assuming they built the original product).

Since they are familiar with the current product, it facilitates their cognitive comprehension of the desired changes if we provide them with a compare and contrast spec that is annotated. The result being that we are working with their current mental model and then gently ushering them into the new design. The annotations help quickly identify the differences. And the side-by-side presentation allows them to

  1. not work from memory, and
  2. be able to quickly identify the differences visually.

Compare and contrast is a teaching strategy employed at all levels of curriculum, since it’s so effective at scaffolding knowledge. By bringing this technique into software development, we can make the process more delightful for everybody involved – especially the engineering staff that needs to interpret the specifications. But similarly for stake holders that need to understand and sign off on designs before they get moved to the development stage.

Since employing this technique in my specs, I find that there is much less back-and-fourth, much less “mansplaining” and simply a lot more calm around the design handoff process. If you haven’t tried it yet, I strongly suggest you do.
