Lean testing

how to make your testproject as efficient (and effective) as possible

Applying the 7 principles of lean software development towards testing (I need to work them out more!)

1. Eliminate waste

a. Anything that does not create value for a customer is waste

b. Make something that is not immediately needed

c. Waiting is waste

- the power of agile; testers don't need to wait until the end, they should be involved at every step

d. Extra processing steps are waste

e. Don’t do anything that doesn’t add direct value eg. - use checklists, rather than test plans

f. Defects are waste!!! - catch them early, eliminate ambiguity in stories by elimating assumptions and asking the tough questions, unit tests, automated regression tests ....

1. Amplify learning

1. Decide as late as possible

1. Deliver as fast as possible

eg. Work with dev team to test each story as it is completed

1. Empower the team

1. Build integrity in

a. Perceived integrity: the totality of the product achieves a balance of function, usability, reliability, and economy that delights customers b. Conceptual integrity: the system’s central concepts work together as a smooth, cohesive whole c. Fitness for purpose vs. conformance to requirements

1. See the whole

(AT: I did start reading the book, but couldn't finish it. Somehow this is just one step too far for me. I think Lean development is beyond agile development, and we don't even know where we are with agile testing...)
