Never Waste A Good Crisis
When hard times (recessions, financial
crises) hit the usual reaction is to cut cost in every possible way.
Rarely do managers propose new improvement programs or the
acceleration of existing efforts. But a
crisis is often the best time to implement Lean Manufacturing. Many of the most successful practitioners and
originators of Lean started their efforts in the midst of a crisis.
We show examples here from
Ford Motor
Company,
Toyota and
Harley-Davidson.
There are several reasons why a crisis
is the best time to start with Lean. First, a crisis makes the
required paradigm shift easier
and faster. Second, Lean programs should be
self-financing and not require injections of cash.
Finally, the cash-flow benefits come very
quickly.
The Paradigm Problem
A paradigm is a
philosophical or theoretical framework; a way of looking
at the world; a mental model (in Senge's terminology). Paradigms operate at both the individual
and organizational level.
The human brain, being essentially
a self-organizing pattern recognition system (in DeBono's words),
tends to bend external facts and phenomena into the established
paradigm. The paradigm or model only
changes when facts and phenomena can no longer be stretched to fit
the paradigm.
In the world of manufacturing, certain
paradigms were established in the period from about 1890-1930 when
manufacturing had its greatest successes. But the world has changed
a lot and the old paradigms are not always valid.
Past success makes a paradigm even more difficult to
dislodge or change.
Lean operations require a major paradigm
shift. When times are hard and the
situation desperate it is difficult to ignore the fact that the old
paradigm is not working. Hence, the organization is more
open to change.
Self Financing
A well-planned and executed Lean
implementation is generally self-financing, i.e., the increased
positive cash flow pays for the implementation as it goes along.
This is especially important when times are
tough and credit is unavailable.

Early Cash Flow
Unlike most business improvements such
as computer systems and new equipment, Lean requires
little expenditure early in the
program and the most dramatic results come
early. The figure below shows generalized net cash flow
from a well planned and executed implementation.
In the first few months of an
implementation, expenditures are usually for some preliminary
training, a few kaizen events and changes in procedures.
This results in significant
inventory
reductions that bring in a lot of cash. Productivity
improvements require more time and the cash flow is less than the
cash flow from decreased inventory.
Later in the implementation, the costs
are greater because the activities may include more in-depth
training and more investment in equipment and systems.
However, by this time productivity
improvements are contributing to the positive cash flow.
Inventory reductions, while less then they were initially, are
likely to continue for several years.
Another way to look at this is to think
in terms of exchanging inventory for excess capacity. There is a
relationship between inventory and capacity as discussed in our
article Inventory, Capacity &
Delivery.
The Gift of Desperation
The
pages below contain three examples of
well-known firms that were forced into Lean by a crisis. In each
case, the organization was presented with certain catastrophe if
they continued upon their past course. Yet, the crisis forced them
to abandon old paradigms. It led them to a course that not only saved
the day but positioned them for decades of growth, profitability and
leadership of their industry. The crisis, it turns out, was a
gift--the gift of desperation.
