Continuous improvement knowledge for anyone ... anywhere ... anytime.
The MRP evolution took us down the road of computer
sophistication. It was to be the panacea for solving all manufacturing
problems. Little did we know that when we finally arrived at the final
phase---ERP---that we would still
be facing daily parts shortages, shop floor disasters and end-of-the-month
chaos. What happened to all those promises?
MRP/ERP, at first look, are not complicated systems. We input a master
schedule that uses bills of material and parts procurement lead times to
calculate gross requirements. These requirements are then balanced
against the aggregate of on-hand inventory, work-in-process and open
purchase orders to determine the net, time phased requirements. The
resultant is subjected to lot size algorithms and planned orders are
created. (The final output is notification to planners in the form of
action messages to either reschedule, reorder or cancel shop and/or
purchase orders.)
If we go deeper into what is happening in the gross to net requirement
process, we find that many calculations are made based on the data and
systems parameters supplied and maintained by planners. While a computer
is flawless in its ability to calculate the answers, the data supplied by
the planner is not. Consequently, the answers are subject to human error.
In our "ShowTime!" presentations we do an exercise in
statistical probability. Each participant writes down what he/she knows
(or guesses) to be the percentage accuracy of their company's master
schedule input data. To arrive at the aggregate input accuracy of the
master schedule, they convert the percentages to decimal equivalents and
multiply each to the other. (statistical probability is not the averaging
of the decimals, as many people think).
Using the same statistical probability approach, the resultant decimal is
used as the master schedule accuracy input into the requirements planning
step to calculate a shop order launch accuracy. An accuracy level of 0.70
or 70 percent (70%) is quite common and indicates that their order
launching and rescheduling efforts are based on a system error of 30
percent. Is
there any wonder why MRP and ERP are not the panacea we once thought them
to be!

An effective method for evaluating how well a company is doing in managing
their MRP input data is to ask questions as to how accurate are their
bills of materials, how accurate is their purchase order status, how
accurate
are their inventory records, etc. If the answers you get are vague,
like---good, OK, not too bad---then you know that this is a company that
needs help in stepping up to the problems of poor information integrity.
If a company is
not measuring their system's data integrity, nor in constant pursuit of
continuous improvement, then their results will always be poor and their
production environment will surely produce shop floor chaos and late
deliveries to internal schedules and to customers.
For a measure of MRP/ERP shortcomings, one needs only to spend some time
in a manufacturing facility---especially during the last weeks of the
final financial quarter. In a typical company, you'll find that converting
the quarterly
financial forecast into reality still requires overtime, internal/external
expediting, last minute on-the-run product changes and even a little smoke
and mirrors. Results are scrap, rework and warranty costs that negatively
impact a company's bottom line performance.
In addition, marginal quality and late shipments deliver less than
acceptable customer satisfaction. Companies that have spent thousands of
dollars in pursuing MRP/ERP are devastated when they experience a business
decline due noncompetitive pricing caused by uncontrolled operating costs.
Is there an alternative? Certainly, we call it Kaizen Based Lean
Manufacturing™.

Kaizen (pronounced Ky'zen) is the Japanese word that means gradual,
continuous improvement. In my experience, managing a continuous
improvement project is difficult but a kaizen program presents a unique
challenge. The kaizen program has no end. It is sustainable and successful
only when management has made a commitment to stay the course---
discipline and tenacity are basic requisites for kaizen success.
Kaizen Based Lean Manufacturing™ (KBLM) is a proven methodology that
employs practical tools and techniques that optimize manufacturing
performance and helps companies to consistently
exceed performance expectations.
KBLM involves arranging and defining manufacturing
resources so that products flow most efficiently through the manufacturing
process. Today, most manufacturing companies are still organized for
functional manufacturing---mechanical assemblies, electronic boards,
cables,
machined components and purchased parts are produced or purchased in lot
sizes and received, inspected and moved to stockrooms. This process
includes the "picking-of-parts" to fill shop orders and the
movement of shop
orders to the production machining and assembly build areas. When the
parts are completed, they are returned to the stockroom to be
"picked" for the next higher assembly shop order. Finally the
end product is "picked", assembled, tested and accepted. KBLM
eliminates all the non-value-
added tasks in this "order launch and expedite" system---the
result: A significant increase in quality, speed and profits.

No matter how much sophistication is added to computerized shop floor
control systems, if we fail to master the eight basics of KBLM, we will
never eliminate the chaos that grips our shop floor day-to-day activities!
How can you learn more about the shortcomings of MRP/ERP and the benefits
of Kaizen Based Lean Manufacturing™? We are planning a special 4-hour
breakfast presentation on "ShowTime! A Bill Gaw MRP/ERP Wake Up
Call." It will be an action learning experience that will feature
MRP/ERP and KBLM simulation exercises followed by an interactive forum.
This cost- effective presentation will help your manufacturing team:
- Understand the power of Kaizen Based
Lean Manufacturing™ (KBLM)
- Realize the shortcomings of typical
MRP/ERP scheduling systems
- Question current manufacturing paradigms
and operating methods
- Commit to planning and implementing KBLM
to help:
--- Eliminate shop floor chaos and "end-of-the-month"
syndrome
--- Step up improvements in quality, speed and profitability
--- Shift paradigm from "firefighting" (reactionary) to
proactive problem solving
