Measuring Interactivity with TTI: Time To (consistently) Interactive

When we talk about web performance measurement, what we’re actually trying to determine is the moment when a user can effectively achieve his or her goal. Meaning the users can consult the content they are looking for and/or interact with the page  in a satisfactory way. Some metrics endorse rendering actions by the browser, others measure the progress of the display through the recording of a video. However, a great mystery remains: how to properly measure interactivity.

For a few years now, Google has been pushing an ambiguous metric: Time To Interactive. What does it mean? Let’s define it and explain how and when to use it (or not).

5 days together: taking a step back to move forward

Although we work in the same company, the daily life of each Dareboost collaborator is very specific. About a year ago, we have hired our first remote workers. That was a new organization to be found. We do not live in the same place, don’t have the same jobs or routines, and it sometimes does not make it easy to share our successes, our doubts, our feelings. We’re enthusiastic and absorbed in what we’re building, but we also need to take a step back, once in a while, to nurture our vision and company culture.

We regularly meet in Dareboost’ headquarter (Rennes, France) for a few days of brainstorming where we alternate between workshops, indoor or outdoor activities, and friendly meals (long live the raclette!). Continue reading 5 days together: taking a step back to move forward
