D6 - Problem Detection and Reso Flashcards
This can help the cause of a problem might be
RCA
These are uncertain events or conditions
risks
this helps tracks risks
Risk log
These are risk events that have occurred
issues
this is a risk that can occur when a risk is resolved
secondary risks
backlog of work that is caused by lack of clean-up, maintenance
technical debt
This help address technical debt
refactoring
Causes of technical dept
poor upfront definition, pressure to deliver value, lack of doc, parallel development
These help create a safe and open environment
brainstorming and retros,
Examples of failure modes
we make mistakes, prefer to fail conservatively, prefer to invent rather than research, we are creatures of habit, we are inconsistent
Examples of success modes,
good at looking around, we can learn, are malleable, take pride,
Strategies for creating success
balance discipline and tolerance, start with something concrete, copy and alter, watch and listen, support both concentration and communication, match work to the person, retain the best talent, use rewards, combine rewards, get feedback
these types of defects were discovered after testing and release
escaped
Defects should be fixed
When discovered
This tests all functionality
regression
This should be done to confirm work is done
demos
These will discover defects
UAT and end to end testing
Our goal for defects should be
To fixe before release
this is the time it takes to go through the whole process
lead time
this is the time it takes to go through part of the process
Cycle time
Example of cycle time
coding to testing
Example of cycle and lead time
concept to shipping
Way to improve cycle and lead time
stop taking requirements, crashing
A hint to poor velocity
poor sizing
This is the amount of time between when a defect is detected to fixed
defect cycle time
The long the defect cycle time
the more expensive
defects that escape inform
defect rates
Types of variance analysis
cost, schedule and planned
This is an unusual occurrence that results in work not being done
special cause variance
Goal of trend analysis
predict future performance
Lagging metrics
measurement of past experience
Leading metrics
provide view to the future
This type of backlog where risks are handled first
risk adjusted backlog
EMV
expected monetary value. Probability, x impact
Risk response
mitigation, transference, avoidance, acceptance
