生命周期是一款产品“生老病死”的过程，在这个大的过程之中，又嵌套叠加了无数用户从新增、留存、活跃、到沉默的小过程。对这些过程的分析和理解，能让我们对产品和用户有更深入的，更数量化的认知，进而辅助到日常的运营工作中。本文总结了几点对生命周期分析工作的思考，包括一些数据处理的技巧，主要环节的分析和价值点的挖掘等。

在计算机科学中，柯里化（英语：Currying ），又译为卡瑞化或加里化，是把接受多个参数的函数变换成接受一个单一参数（最初函数的第一个参数）的函数，并且返回接受余下的参数，而且返回结果的新函数的技术。这个技术由克里斯托弗·斯特雷奇以逻辑学家哈斯凯尔·加里命名的，尽管它是 Moses Schönfinkel 和戈特洛布·弗雷格发明的。柯里化其实也是函数式编程的思想。

在数据驱动时代，不管是在产品功能迭代还是策略决策时都需要数据的支撑。那么，当我们准备上线一个新功能或者策略时，如何评估新老版本优劣，即数据的可量化就成了问题。这个时候就需要引入 A/B Test 了。

In 2020, we announced that React Native is the future of mobile at Shopify and since then we’ve been migrating all our native mobile apps to React Native. Since each app is different, there is no single approach that works for all of them. So, we evaluated all the possible options for each app and chose the ones that best suit their needs.

Shopify Point of Sale, for instance, had come a long way since it was first built during an internal hackathon. It was originally designed and built to support small mom-and-pop stores or weekend warriors. However, it has surged in popularity and is being used by some of our biggest merchants and is processing transactions worth billions of dollars each year. The codebase had accumulated a lot of tech debt and the app’s UX was also not serving the needs of large merchants who have hundreds of locations and tens of thousands of products. After a thorough evaluation, it became clear that we couldn’t fix these issues with incremental changes. Hence, we decided to do a full rewrite, which has been a big hit with our merchants.

Shopify Mobile, our flagship mobile app, on the other hand is quite stable and meets our merchants’ needs. It is also our largest app at 300 screens per platform and took over six years to build. Rebuilding it from scratch would be a massive undertaking. Even if we assume that we’d be twice as productive with RN (which is not necessarily the case always), it would take us at least three years to rebuild. That’s a very long time. We would have to halt all new feature development during this time and in the end have the exact same app as we started with. A rewrite then, was clearly out of question.
