sizes. 2. Large batch sizes result in skyrocketing levels of WIP and high levels of variability in flow that cascade through the entire manufacturing plant. The result is long lead times and poor quality that causes delay for the customer, such as activities that can be bypassed without affecting the result. The following categories of waste and hardship come from Implementing Lean Software Development

hypothesis 1. Barry O’Reilly, Lean Enterprise describes as: We Believe that Will Result in . We WillHave Confidence To Proceed When result. Pairs typically consider more design alternatives than programmers working alone and arrive at

environment interactions 3. Ch. 10 Enable Fast and Reliable Automated Testing a. Undesired outcomes result from finding and fixes errors in a separate test phase. b. Delayed feedback fades the cause & effect environments are synchronized and consistent e. ENABLE AUTOMATED SELF-SERVICE DEPLOYMENTS i. As a result of compliance, oversight, and control needs separate Operations groups have emerged ii. Widely

which developers can produce something, get feedback, and then adjust what they have produced. As a result, the code can be developed in a user-centric way and match the enterprise’s needs precisely. Risk

and compare. We are comfortable with the ideathat we will break things in testing, because the end result of doing so is that we can make a decision more quickly and with more good information available
