7 lean principles?
Eliminate waste Build in quality Create knowledge Choose as late as possible Deliver as fast as possible Empower the team Emphasize se the whole
What are examples of waste?
Wasted time, capital, brain power, defects, poor planning, poor MVP design
What does build-in quality entail?
Everything must be high quality, including the details
Lots of testing, good design processes, automation, constant feedback
What does create knowledge entail?
Requires self-discipline and process
Documentation, sharing info with team, open culture…team
Why commit as late as possible?
Always unknowns so commit late so that other elements facilitate visibility
Late=more informed
Why deliver as fast as possible?
Speed=competitive advantage
What user wanted during design I’d still what they want at delivery
What does empowering the team mean?
Listen to developers
Sparks creativity and results in higher quality work
What does optimize the whole entail?
Think about product as a whole
Too much focus on subsystems can result in overly designed and complex subsystems that are hard to integrate
What is waterfall development
Design happens sequentially
More suitable for HW
What is iterative development? What is it used for? Compatible with?
At each given time, more than one iteration of the product design/development cycle is being conducted
Long and large projects
Compatible with agile, suitable for SW
What is backlog?
List of deliverables necessary for project
What are the 2 backlog rules?
If not necessary, deliverable should be removed
If new item is known during development cycle, it gets approved by leads and added to backlog
What are the 6 steps of testing?
Component/subsystem Integration testing (do components work together?) Full system/ unit testing Field testing Iteration on user testing and feedback Beta releases (flush out scale bugs)
What is quality assurance?
About avoiding mistakes and preventing a faulty product
Happen at all stages
Should be quantifiable
What is quality control? What methods does it involve?
Encompasses QA and usually post development
Failure testing, statistical control, company quality, total quality control (done when everything ok but sales still drop)
