kaizen involves encouraging staff to continually find new, better ways of working, to keep quality and productivity rising regularly
an example of kaizen
toyota claims to have tens of thousands of new ideas each year from factory-floor workers, each one focused on making the business even better
an advantage of kaizen
steady progress makes it easier to adjust to rising productivity without the need for big rounds of redundancies
disadvantage of kaizen
the business may miss the chance to make a big leap forward, ie by rationalising production
Just-in-time (JIT) production
Ordering materials in smallquantities but often, to arrive justintime before existingstocks run out. This means carrying zerobuffer stocks
example of JIT production
on a motorbike production line, fresh supplies of headlights arrive just as the last one is being fitted to a bike
an advantage of JIT production
the elimination of buffer stock saves this drain on working capital, and forces the business and its suppliers to work with zero defects, as one faulty component can halt production if there are no spares
a disadvantage of JIT production
an unforeseensupply hold-up (ie serious motorway crash) may halt all production
lean management
lean management broadens out the original concept from manufacturing to all organisations (especially service businesses)
an example of lean management
the manager of an office might want to see minimum wastage of resources (ie paper, space) and would want to see time used as efficiently as possible
an advantage of lean management
if one bank or supermarket head office is more efficient than its rivals, it can pass on the lower costs as lower prices to customers, and perhaps gain market share
a disadvantage of lean management
lean can sometimes stray towards mean. a mean-spirited employer that thinks only about cost minimisation can be attractive to staff. in 2017 a ryanair problem with staff retention (pilots getting jobs elsewhere) led to widespread flight cancellations and bad publicity for the airline
long term relationships
lean producers want long term supplier relationships based on trust, not contracts. other products tend to get suppliers to compete for the lowest-priced quote
example of long term relationships
toyota UK has 260UK-based suppliers of car components. all of these are based on long term trust - some of these relationships have been running for 30 years
advantage of long term relationships
long-term relationships encourage suppliers to think how to develop new, better (perhaps technically more clever) components, to help their trusted customer become more successful
a disadvantage of long term relationships
unit costs may be higher than rivals, especially in the short term. this can affect competitiveness
make to order (lean production)
only manufacture in response to a specific customer order, ie don't produce for stock/inventory
example of make to order (lean production)
when you order a mercedes it will come with perhaps 25 options chosen to match your wishes ie metallic blue paint. it will be personalised to you, but this also gives the company time to maketoorder
advantage of make to order (lean production)
making to order allows a business to operate with zero finishedgoodsbufferstock
disadvantage of make to order (lean production)
businesses that make to order cannot respond to a customer desperate to get the product quickly
no bulk-buying (lean production)
lean producers buy little and often to avoid high stocks when buying in bulk
example of no bulk-buying (lean production)
a supermarket orders small numbers of croissants to arrive everyhour.
advantage of no bulk-buying
goods are fresh and there's no wastage from goods going beyond their sell-by-date
disadvantage of no bulk-buying
removes the possibility of gaining cost advantages by bulkbuying (economies of sale)
participation (lean production)
lean producers encouragestaff to put forward ideas they have of how to make better, more innovative products
example of participation (lean production)
toyota (inventor of lean production) hires university graduates to work on its production lines, and encourages these talented people to explore the potential of its technology
advantage of participation (lean production)
putting into practice great ideas from your ship-floor staff boosts morale and motivation
a disadvantage of participation (lean production)
staff will get frustrated if ideas are called for but not implemented
right first time (lean production)
avoiding waste by working to get production right firsttime, rather than relying on checking systems (quality control) and re-work
an example of right first time (lean production)
requiring that fitters of car doors have a 100% successrate instead of needing some of the work to be re-done by quality checkers further down the production line
advantage of right first time (lean production)
eliminates the waste of materials and labourtime involved in having to do things twice
disadvantage of right first time
may be too challenging for new, inexperiences staff whose quality standards are not yet high enough
zero defects (lean production)
faultless production standards, thereby allowing zero buffer stock within the production process
an example of zero defects (lean production)
if you can be confident of fault-free cup handles arriving just in time, you don't need any in stock
advantage of zero defects (lean production)
zero defects can help build a strong, quality reputation among cutsomers, perhaps adding value to the brand name
disadvantage of zero defects
achieving zero defects may be expensive in equipment and labour costs
