Last night, Twitter curtailed Meerkat's access to its graph. I saw lots of discussion on Twitter (I'd say this was ironic but it's just expected) about why and whether Twitter should just compete on its own merits with its recent acquisition Periscope. Some have termed what happened to Meerkat “platform risk," and it is, but one must be willfully naive to consider ad-monetized social graphs like Facebook and Twitter to be capital P Platforms.
CoachingSearch.com recently posted an article about Ohio State's football program in which Urban Meyer, the Ohio State coach, described how players' practice repetitions were tracked. In this case the goal is to prevent injuries. (Yes, I'm a college football addict. But I digress.)
The article has a lot of parallels in the product management world. I'm a firm believer in using repetition to build PM "muscle memory". How many times have you cranked out a requirements doc? Or reviewed a cohort chart for outliers? Or proactively scheduled a customer interview? Did you do it monthly? Quarterly? Ad-hoc? Did you notice any improvements in how you "did the rep"?
So much of the PM discipline is just that - discipline. Using a checklist and sticking to it. Measuring your company's / catalog's / team's metrics on a regular basis & learning from it.
I'm nowhere near the 2,000 Rep Club. That's why I'm still learning. You should be too.
