客户旅程是从一个特定用户的角度出发，记录用户与产品/服务进行接触、进入以及互动的完整过程。

客户旅程不仅可以遍历整个用户体验的过程，还可以用它来遍历任何问题的发生过程「Before, During, After」，以便找到解决方案或者优化问题。

近期在负责一个客服流量智能调度工具的交互设计，其中涉及一个比较有趣的交互 - 书写规则表达式，这类交互不常见且一般只存在于B端，体验往往容易被大家忽视。我们来看看从设计的角度，是如何帮助咱们的客服运营同学更高效地编写规则表达式。

主要分享基础的3D城市要素和一部分性能优化。

短视频作为内容重要的承载方式，是吸引用户的重点，短视频的内容与体验直接关系到用户是否愿意长时停留。因此，体验的优化就显得尤为重要。上一篇我们分享了 iOS 短视频秒播优化，这篇我们来聊聊 Android 端的优化。

Uber’s backend is an exemplar of microservice architecture. Each microservice is a small, individually deployable program performing a specific business logic (operation). The microservice architecture is a type of distributed computing system, which is suitable for independent deployments and scaling of software programs, and so is widely used across modern service-oriented industries. Uber has a few thousand microservices interacting with one another via remote procedure calls (RPC).

A service request arriving at an entry point (aka end-point) to the Uber backend systems undergoes multiple “hops” through numerous microservice operations before being fully serviced. The life of a request results in complex microservice interactions. These interactions are deeply nested, asynchronous, and invoke numerous other downstream operations. As a result of this complexity, it is very hard to identify which underlying service(s) contribute to the overall end-to-end latency experienced by a top-level request. Answering this question is critical in many situations, for example:

• Identifying optimization opportunities for a top-level microservice
• Identifying common bottleneck operations affecting many services
• Setting appropriate time-to-live values for downstream RPC calls
• Diagnosing outages and error conditions
• Capacity planning and reduction

While latency is one of the metrics of interest, other metrics such as time-to-live, error rates, etc., also fall in the scope.

Pinterest is a visual discovery engine that helps Pinners find inspirational ideas. Advertisers use Pinterest to connect with Pinners on these journeys to inspiration, and seek to promote products or services efficiently.

The Ads Intelligence team at Pinterest builds products that help advertisers maximize the value they get out of their ad campaigns. As part of that initiative, we have recently launched the Campaign Budget Optimization product for Pinterest Ads.

Campaign Budget Optimization, or CBO, is an automated ads product that benefits advertisers by distributing the advertising budget for each campaign across the underlying ad groups in an automated manner. The goal of Campaign Budget Optimization is to:

• Maximize advertiser value, for example driving clicks or conversions, depending on the campaign
• Improve the budget utilization of the campaign by allowing the budget to be shared across ad groups
• Simplify the advertiser experience and eliminate the need for manual budget adjustments

对亲密关系而言，吵架只是一次感冒，但影响确实可大可小。好的复盘，可以助你们更快痊愈。

当我们空降到一个公司以后，面临的环境是非常复杂的：下属觉得新领导是来抢夺胜利果实的，平级的同事会趁机跟这个屁股还没坐热的“新兵蛋子”抢夺资源，老板往往对新人的期望很高。

一些缺乏经验的空降兵急于表现，在没有对局面进行认真分析的情况下，就贸然大刀阔斧地进行改革。比如：沿用上家公司的管理模式和方法；贸然增加IT预算；花了太多时间在业务学习上，却忽略了文化和政治因素等等。

其结果想想就知道了：下属抗拒他的新举措、阳奉阴违；同级继续对他碾压，勾心斗角；老板对他失去了耐心，失望透顶。
