Process Analysis and Improvement Flashcards
why do we record the flow of customer/info/products in process analysis
- easier to understand the flows (communication and training purposes)
- helps identify improvment opportunities
what are the important symbols
rectangle: task
upside down triangle: any wait time (even things like inventory waiting on a shelf)
diamond: decision points
who should be doing process improvement
the people direclty invovled in the process!

cook-customer place order

how did toyota use process improvement in blood services
does blood have a long shelf life
no!!!! very perishable
what did toyota do in canadian blood services
3 improvements
-improved the blood supply chain by applying the toyota production system
- improvement #1: standardized work
-making flow of work a circle (Walk less, minimize time) - improvement #2: reduce burden on team
-less time in freezers - improvement #3: reduce wasteful motion
-gained an additional 1 hour per day
how many canadiands donate blood? out of 12 million
only 4%
are there suppliers in th eblood supply chain? can they be paid?
no!!!! only 4% of people do so you cannot dissapoint suppliers
is there certain supply or demand in the blood supply chain?
no!!!! supply ucertain (depends on donors) and demand can fluctuare
canadian blood services case summary
this describes the process flow, but the process is basically inefficient, as sometimes customers can spend 1 hour before being turned away
how could we make the blood donation process better?
move the fill out questionaire and checking it to the start iin the process!! before even pricking
-improved donor service (less time waiting)
-saves iron test supplies and labour
-only enter the complex info if they will donate
could the blood donation processs be improved even further?
yes!! have a questionaire on the website for people to do before they even come
-or have signs up that will tell you ou are ineleigible
note about process analyssi visuals
ALWAYS DRAW OUT THE INGREDIENTS/INPUTS
this is triangle
also DRAW OUT THE FINISHED GOODS THAT ARE UNSOL
also triangle
how to do process analysis
- draw the visual out!!! take care to note all inputs ccarefully and all steps
- now identify each stage#, and do the capacity per hour calculations
- along the y axis have all the stages, and the x acis has capcity per hour, capacity per week, demand per week, excess/short
- identify the stage with the lowest capacity (this is the stage that is the bottleneck)
- analysis, if we ease the bottleneck stage, what becoes our next bottleneck?
synonym for bottleneck
capcacity of the prcoess
3 parts of the process improvement
1) recognize need for change
2. resarch best practices (benchmarking)
3- determine how to change (tinker/teardown)
How do you recognize the need for change?
look at the warning signs that the business process may need improvement
what are the 4 types of warning signs (prcoess improvement step1)
Internal Leading
Internal Lagging
External Leading
External Lagging
what does leading and lagging mean
leading is something that is giving you immediate feedback that the process is ass
lagging is something that will give you delayed feedback that the process is asss
internal leading warning signs (4)
-excess delays or having really high inventory
Why is this the case?
-high rework/scrap costs
Why are a lot of things going to scrap?
-emploee frustration
Look at their faces, why are they upset
-Idle staff/equipment
paid to work!! so not wokring is bad sign
what is internal laggining warning signs
-excess overtime (what are we making up for???)
-employee turnover
-declining kpis!!!
