"The problem is that there are several bottlenecks internally," which include the requirements, specs, and testing. Another one not mentioned in the article.

Before you had faster implementation times, something would take six weeks to implement. Feedback from the client about how far off target you were came through in the same amount of time: a help desk ticket, a post-call check-in, a quarter end review. The price you paid for being off target was proportional to how long it took to figure out.

Now, when you can ship features in an afternoon, the customer feedback loop remains the same speed. Surveys, help desk tickets, and churn analysis come back days, even weeks later, by which point you've shipped five new features going the same way.

You can fix the internal bottlenecks easily enough: write better specs, have faster test cycles, deploy continuously. The customer feedback loop bottleneck is built into the system. It won't get any faster just because implementation did.

Today most organizations are busy fixing the internal bottleneck, but not the external one.
