As a software developer with more than 20 years of experience, I witnessed and went through some awkward situations. I had to create unuseful documentation because my boss wanted to. I saw teams defining story points to a set of user stories and complaining that some user stories were more complicated than they thought at the next retrospective. I've heard about teams creating interfaces with extra features because the designer thought it was helpful to the customer. I witnessed teams with a WIP of more than 200 thinking things were fine. Sometimes it's hard for professionals to see situations like these as waste, barriers or impediments. The research I'm developing in the master's degree aims to help developers being more productive by removing unnecessary impediments. I used Data Science and the concept of waste to do so. It was possible to quantify wastes during the research and present waste trends to teams and managers. The presentation of waste trends helped teams focusing on what matters the most. And it eases the root cause analysis.
In this session, I will present the process and some findings I stumbled upon during the research.
* Trends allow you to anticipate problems without being invasive
* Trends increase visibility of what's going on in the trenches
* The finding process of the root cause of waste was effective to figure out the problem definitively
