Trade-off Triangle: Perf Index-Consistency-UX

[jorydotcom]

Some constituencies are experiencing a trade-off as illustrated by the following diagram:

It seems as though they can pick two, but never satisfy all three concerns. For example:

• Org can keep their content consistent between their normal and AMP pages, and deliver a better user experience (e.g., by not using iframes for embedded content) - but their perf index suffers
• Org can focus on the perf index pieces and maintaining content consistency, but deliver a worse user experience
• Org can focus on the user experience issues and perf index, but the result is different experiences on AMP pages vs. normal pages.

We should define some good cases of this tradeoff and discuss with the AMP TSC

We wrote a short document in EL PAÍS with some thoughts about the issue that you can find here:
