GAP: 5 pcs/h
GOAL: we must produce 1 arrow per 10 minutes
THE SHORT STORY OF
be careful!
Human mind is lazy, and preferring shortcuts than analyze.
Steve is very shy and withdrawn, invariably helpful but with little interest in people or in the world of reality. A meek and tidy soul, he has a need for order and structure, and a passion for detail.” Is Steve more likely to be a librarian or a farmer?
answers:
librarian
farmer
male farmers to male librarian ratio (USA):
20:1
Kahneman and Tversky's Experiment
2,4,8,16,32...
what is the rule for this sequence?
obvious solution doesn't have to be the right one
n<n+1
try to think simply when defining the problem
hello, it support, how can i help you?
i have too many items in autostart
do you want me to delete some of them?
NO! i need them all
so, what is your problem?
my system starts very slow
beware of using cause as a problem definition
STEP 1
Understand process and validate measurement system
process-map the as-is process
identify process inputs outputs
collect data
ACTIVITIES / TOOLS
OUTPUTS
detailed process map
output variables and their measurement
performance data
STEP 2
Determine process capability
control charts
capability analysis
ACTIVITIES / TOOLS
OUTPUTS
baseline control charts
baseline capability
DPMO
STEP 3
Finalize performance objectives
cause and effect analysis
FMEA
review of project goals and plans
ACTIVITIES / TOOLS
OUTPUTS
revised project goals
quantified project objectives
prioritized risk
cause and effect relationship
assembly arrowhead
assembly fletching

BE PATIENT!
It is the phase of collecting information
It is not the time to draw conclusions
ok, how much ram do you have?
so, you think it is a not enough memory problem?
no, how many apps you have in autostart?
oh! i knew it, to many apps in autostart
no, i'm just asking, how old are you?
do you think i'm too old to have a computer?
STEP 1
Identify sources of variation
detailed process map
brainstorming
fishbone diagram
cause & effects diagram
ACTIVITIES / TOOLS
OUTPUTS
identified sources of variation
updated process map
updated FMEA
stones too hard?
chicken running away?
big level of humidity?
slippery twine?
enchanting too slow?
unnecessary steps in process?
STEP 2
Identify sources of variation
graphical analysis
hypothesis testing
correlation and regression analysis
ACTIVITIES / TOOLS
OUTPUTS
identified improvement oportunieties
statistical analysis of data
potential x's critical to process
unnecessary steps in process
why?
- those steps are in project specification

why?
- at the beginning customer ordered enchanted arrows
specification was not changed

why?
- chief doesn't update it

why?
- he doesn't know that it is important

why?
- we have no standards for change, we don't know what is important


STEP 1
Determine variable relationship
DoE
regression analysis
ANOVA
simulation
ACTIVITIES / TOOLS
OUTPUTS
realtionships between x's and y's
KPIV settings for optimum process output and minimum output variation
STEP 2
Establish operating tolerances
establish relationships between x's and y's
use optimum setting for x's
determine new process capability
cost/benefit analysis
ACTIVITIES / TOOLS
OUTPUTS
optimum robust settings for x's
updated project plan
established implementation plan
STEP 3
Confirm results and validate improvements
confirmation experiments
