Michele shares her journey in the software industry and how she got involved in product development. Customer interviews are not just something for product people -- Michele shares concrete ways that developers can get value from talking to their customers. She also shares a few tips for how to get involved with the customer research process and how to convince stakeholders of the value of the process (if necessary). They also discuss what the different between empathy, sympathy, and compassion. Empathy is understanding someone else's context and perspective. Since empathy is not something that comes naturally to everyone, Michele shares some tips about how to learn to become empathetic and become a better listener.

Alex Bramley talks to Sven Johann about the basics of service level objectives. They begin with terminologies (SLI, SLO, SLA, Error Budget), look at costs of outages and discuss what reliability has to do with customer happiness. They continue with having 100% reliability is the wrong target and what’s possibly the right target. Alex then explains how to get started with collecting data about your system’s behaviour. They close the first part of this series by looking into latency SLIs.
