TOPIC 5
Managing Production
‘Fordism’ versus ‘ToyotaismLearning Objectives
• At the conclusion of this topic, the student
should be able to:
– Describe the elements of a Fordist production system;
– Explore the factors that have contributed to the
demise of Fordism;
– Identify the main features of a lean production
system, and contrast this system with alternative
forms of production;
– Provide relevant examples of mass and lean
production systems.Managing Production
• Scientific Management contributed significantly
to ideas about the best way to manage
production from a ‘micro’ perspective (ie: from
the point of view of what each individual worker
contributes);
• As technology improved and automation was
introduced, a new set of challenges ensued;
• These challenges were faced in the first instance
by the automobile industry in the US.Mass production & the
Automobile industry
• Largest global industry
• Developed in US, but now dominated by
Japanese production methods
• Major influence on contemporary management
practices
• 4 production regions:
– North America
– Japan
– Europe
– Low labour cost (varies):
• Mexico, Brazil, Korea, IndonesiaCraft production: 1890s
• ‘Hand-built’ cars to order;
• Components made by subcontractors:
– No standard gauging system; and
– No tools to cut hardened steel.
• Varied quality of components;
• ‘Fitters’ fit each component by hand.Characteristics of craft
production
• Highly skilled, largely self-employed,
workforce;
• Built on decentralised organisation
coordinated by owner/entrepreneur;
• Use of general purpose metalworking
tools; and
• Low production volume, with no two cars
exactly the same.Weaknesses of craft production
• Production costs not reduced by volume
(no economies of scale);
• Consistency and reliability hard to achieve;
• Quality problems because lack of
systematic testing; and
• Inability of small producers to achieve
technological innovation.Mass production: 1914?
• Machine tools able to work hardened
steel;
• No warping from hardening process;
• Standardised parts;
• Innovative design; and
• Car components easier to assemble.Ford’s innovations
• Assemblers specialised in a single task:
– Average task cycle reduced from 514 to 2.4
minutes.
• Moving assembly line (1913);
• Less labour per automobile; and
• Economies of scale: unit costs decline as
volume increases.Craft versus mass production:

Complete vehicle 750 93 88The Ford workforce
• 7,000 workers;
• More than 50 languages;
• Single tasks for assemblers;
• Only limited training needed (minutes);
• Pace set by assembly line; and
• ‘Standardised’ worker.Specialised work
• Foremen;
• Machine repairers;
• Quality inspectors;
• ‘Reworkers’ – craft workers who corrected flaws
at the end of the line; and
• Specialist engineers:
– Industrial engineers (assembly operations);
– Manufacturing engineers (production machinery); and
– Product engineers (product design).Organisation
• Ford initially an assembler (eg bought
engines, chassis, and other parts);
• By 1915, parts manufacture done by Ford;
and
• Vertical integration – included coal and
iron mines, steel mills,glass factories,
railway lines, ships etc.Tools
• Specialised, single-purpose machinery;
• Machines laid out in assembly sequence;
• Mostly automated;
• High capital expense;
• Low skill; and
• Low unit costs.Product
• Initially one basic design;
• Ease of repair – car repaired and
maintained by user;
• Growth in demand fed by falling prices;
• Variable quality; and
• Emphasis on speed and volume of
production (yield).Mature mass production
• US dominance peaked in 1955;
• 3 large auto manufacturers accounted for
95% of US market;
• 6 models accounted for 80% of sales;
• Growing unionism, entrenching seniority,
job rights and work rules; and
• Increased competition from Europe.The rise of lean production
• Toyota moved into car production post-WW2;
• Tiny domestic market, demand for wide range of
vehicles;
• Labour laws strengthened position of workers.
No immigrant workers;
• Import of Western production technology difficult
(shortages of capital and foreign currency); and
• ‘Lean production’ – craft production for mass
markets.Example: stamped body parts
• Bodies produced by welding together 300
parts;
• Parts are stamped from large rolls of steel
sheets then pressed (stamped) into shape;
• Could produce >million units/year (high
wastage rates); and
• Presses dedicated to single part –
required specialised skills to change.Toyota presses
• Re-designed from second-hand American
presses;
• Quick to change – 3 minutes;
• Easy to change – could be done by assemblers;
• Fewer presses producing many parts in small
lots;
• Economies achieved by:
– Low inventory; and
– Less quality problems (problems show up earlier).
• But required a more skilled and motivated
workforce.Company as community
• Major strike in 1946 established
employment relations:
– Lifetime employment;
– Pay based on seniority;
– Share of profits through bonuses; and
– Workers flexible in work assignments.
• Workforce becomes a fixed cost, therefore
incentives for company to invest in skills.The production process
• Workers organised into teams;
• Team leader works as part of the team;
• Teams responsible for a range of tasks
(repairs, quality control, rework etc);
• Teams spent time reviewing process
improvements; and
• Workers trained to trace errors
systematically.The production process
• Constantly improving:
– Quality; and
– Process efficiency.
• Declining rework rates.The supply chain
• US relations with suppliers based on bids
for contracts;
• Short term relationships;
• Suppliers in competition; and
• Limited information meant little opportunity
for collaboration or quality improvement.The Toyota supply chain
• Suppliers involved in new product development;
• Contracts based on performance specifications,
but left up to the supplier to develop;
• Exchanges of personnel between Toyota and
suppliers;
• Exchanges of technology innovations; and
• Toyota acquires equity in supply firms, and
supply firms in each other.Just-in-time inventory
management (Kanban)
• Mass production based on large inventory
stocks;
• JIT: parts produced in a previous step only
to supply immediate demand in next step;
• Mechanism: containers carrying parts;
• Used containers returning to previous step
triggers production of new parts; and
• No safety net.Product development and
engineering
• Project teams of experts, rather than
specialised divisions;
• Career paths rewarding strong team
players; and
• Emphasis on:
– Responsiveness to consumer demand; and
– Flexible production.Market responsiveness
• Fragmentation of demand:
– 2-car households;
– New, sophisticated features;
– Youth market; and
– Increasingly specialised commercial demand.
• Growing emphasis on reliability.Lean production and demand
• High reliability;
• High product variety (Toyota can produce
twice the range with the same budget);
and
• Shorter product cycles.Conclusion
• Mass production in the automobile industry
replaced by lean production;
• Emphasis on:
– Flexible production techniques (rapid adjustment to
new products);
– Low or zero inventories;
– Total quality management (TQM) – quality control
throughout the whole process;
– Teams of multi-skilled workers; and
– View of employees as a capital investment rather than
a variable labour cost.CRICOS Provider 00115M
