Question #1 If you want to improve something, where do you start?

Question #1 If you want to improve something, where do you start?

Answer: Observation

Example:

If we want to find bottlenecks in our software, we test and gather performance statistics

A historical record of observations produces data that we can analyze to improve

Observations from multiple perspectives may help

The process of observation and analysis is nothing to fear

Self-reflection can be painful but useful

Question #2 What is worth observing and paying attention to?

Question #2 What is worth observing and paying attention to?

Answer: We can’t be sure

Example:

Slow application UI could be due to a problem at any layer

Good strategy is to observe and track anything that might be relevant

Partially depends on what our goals are and how we measure success

Data Gathering and Data Analysis for Software Teams Can lead to new discoveries and understandings

Helps increase focus – the 7% Rule

Seek to Categorize, Not Measure Identify individual and team strengths and weaknesses

Statistics: look at standard deviation (bell curve) or relative rank more than raw numbers
