Fö 5, New approaches Flashcards
Beskriv the history of production management!
- Work study and standardization
- -> Taylor
- -> Gilbreth
- -> 1900-1920 - Flow production
- -> Henry ford
- -> 1910-1950
- -> always get production velocity higher
- -> not really accurate today because we dot have infinit market anymore. More focus on minion cost, resource, material osv. - Total quality management
- -> Demining ishikawa taguchi
- -> Juran shirngo crosby
- ->1940-1980 - Toyota production system
- -> Taiichi Ohno
- -> Eiji Toyota
- -> 1950-2000 - Lean manufacturing
- -> James Jones
- -> Womack Roos
- -> 1990-20**?
Which are the 14 points of TQM? (Total Quality management, by Deming and others)
1.
What is the tree areas in TQM?
- Continous improvement
- Worker empowement
- Focus on costumer
General about TQM?
TRUST
- Trust in supplier
- Get the customer to trust the company
- ->system running more calmly
Describe more about Focus on costumer in TQM?
- Bring costumer to daily work
- ->make sure the custumer requirements are known
- -> who is the customer?
- -> what does the customer wants?
- -> what is quality for the costumer?
- -> everybody (also the operators) should knows exactly what the customer wants!
- -> only supply a perfect product & I only accept a perfect product - Communication
- -> eliminate only oral decisions, whey should always be written where everybody can see
- -> use symbols, pictures and make communication simple for everybody
- -> everybody should know all the organisation processes
- -> leadership: communicate what you as a leader are doing with your time when you are not in the company - Target value
- ->translate costumer needs into target values in measurable (engineering) variables
- -> variability on your product is expensive
- -> except only technological tolerances (not process-related)
- -> QFD, (quality function development)
- ->”Any shifting from target values costs a lot of money! - Taguchi”
4.
Describe more about Continuous improvement in TQM?
- Zero defects
- -> not practically possible
- -> analyze what is defect for us and what is defect for the customer?
- -> make right on the first time
- -> study the process to eliminate the causes of failure
- -> To avoid defects - Use the Deming cycle (Plan- Do- Check- Act)
- -> To avoid defects - right training, education, conditions, communication, tools, information
- -> “Anything that is wrong is costing you money! - Deming” - Project focus
- Define project targets and keep to them
- Don’t launch too much projects –> lose focus
- - Write down procedures and quality measures
- Innovate Continuously
- Give voice to small improvements and daily ideas
- create environment to create ideas
- participate, communicate and get involved, share ideas , aims and ambition with others they will share theirs
- - Eliminate non-quality
- Ask questions: why, what, when, why, how for everything!
- Make war to habits
- -> we always do like this
- -> it’s impossible to do it better
- non- quality costs are very expensive
- “We always have time to fix it when it’s break down, but we never seem to have time to do it right the first time - PeterS. Pande” - Invest in prevention, not in control
4 types of non-quality costs
- external defects (arrive to the costumer)
- internal defects (detected by quality control and does not arrive to the costumer)
- assistent (everything related to quality control, inspections, machines and people that costs money)
- prevention
- -> training
- -> maintainance
- -> information
Examples of non quality costs in companies?
Problem: The external defects is not in any report. Not easy to see.
BEFORE TQM (staple one)
- Cost of bad quality of external defects is often not in numbers
- Make them believe that the cost is tue is a problem??
-
AFTER QC (quality control)
- costs for external defects increases but less cost in external defects and therefor less total non-quality costs as internal defects are less expensive than external defects
AFTER SPC (Statistical problem control) - More assessment cost but reduce internal and external costs. But the probability that that it is wrong is still the same.
AFTER PDCA (plan- do- check- act)
- More cost in prevention. The assessment cost is reduced because of trust, the operators know what to do and the leaders trust them?
- -> kaizen-events
- -> posters
- -> quality manuals
- -> information to operators
AFTER TQOM
- Include people empowerment, if you trust and motivate people. Will increase the cost for prevention but lower all other non quality costs.
A huge invest in prevention is the best way of reducing non-quality costs
