• “Genius” , “Guru to
industry”
• Management- a Science not
an Art
• Introduced the concept of
ongoing improvement.
• Net Profit
• Return On Investment
• Cash Flow
•On being called by Alex, Jonah gave
him the 3 money measurements:
Increase
Throughput
Decrease
Inventory

Decrease
Operational Expense
•Gathers focus group for
operational solutions
•Several concepts which are
polar opposites from general
business operations.
•Jonah reveals that a balanced
plant is where the capacity of
every resource is balanced
exactly with demand from the
market.
•A series of events

•Predictive information that
cannot be determined precisely.
•Interlinked.
•Alex takes his son, David, on a
hike with his Boy Scout troop.
•Uses this hike to understand the
two phenomena.

•Used to understand theory of
bottlenecks later.
•Final throughput-measured by rate
of slowest operation.
•Inventory should be minimized.
•Operational expense must be
conserved.
•Bottleneck - Capacity = or <
than the demand placed upon it
•Non-bottleneck - Capacity is >
than the demand placed upon it.
•Maximum speed = speed of the
slowest operation

•Bottlenecks must be identified
and improved if the process is to
be improved.
•Allows management to take action
to alleviate the constraint in the
future
•Reduce cycle time
•Improve manufacturing cycle
efficiency (MCE)
•Make sure bottleneck time is not
wasted
•Take the load off the bottlenecks
•Quality controls

• 15% increase on sales promised
• Cutting the batch sizes to half.
• Gets his plants improvement
marketed
• Manages a huge contract
• Accomplishes an increase of
about 17%
• Promoted to the division head.

Increase
Sales

Reduce lead

Determine
Bottlenecks

Relieve stress
from bottlenecks
and increase
productivity of
bottlenecks
• Minimum one constraint at a
time in a system
• Over time constraints may
change
• The 5 focusing steps of theory of
constraints are:
If a constraint is
broken in Step
4, go back to Step
1.

Subordinate everything
else to the decisions of
Step 2.

Elevate the
system’s
constraints

Decide how to exploit
the system’s constraints.

Identify the system’s
constraints.
• Improves capacity decisions in
the short-run
• Avoids build up of inventory
• Improves communication
between departments
•Negative impact on nonconstrained areas
•Ignores long-run considerations
•Not a substitute for other
accounting methods
• Global principles of
manufacturing
•Helps to bring order and avoid
chaos
•Not only applicable to
manufacturing world
• Each concept and theory
elongated
•Extremely technical
•Lots of thinking required.
