• By continuously checking small code changes into version control and automating testing and deployment

• By performing exploratory testing

What characterizes the second phase of work in the technology value stream?

• Sequential processing of large batches of work

• Near-Zero defects and low creativity,

• Long and unpredictable lead times

• High variability of process time and high uncertainty
