Publishers Note: We recently challenged our good friend and
maintenance expert Ricky Smith to tell us 10 things we can do
today - not 10 things we can buy today - to improve
reliability at our plants. No new software, no new
hardware, no new consultants. Ricky did as Ricky usually
does and showed up with goods!
We admit he did include one "buy recommendation" but we let it
pass because it falls under US$100.
Here is what he came back
with. - Terrence O'Hanlon, CMRP
Number 1:
Purchase a copy of Terry Wireman’s book “World
Class Maintenance”. Take 4 hours and
sit down with the plant manager, production manager,
comptroller, and yourself (maintenance manager). Answer the
assessment in the front of the book. If you do not understand
the question, go to the chapter which defines the question. If
you still do not understand, then the answer is no. Total the
score and see where you stand. Now we are ready to begin.
Awareness of a problem is the start. Understanding that everyone
sitting in that room owns reliability and thus owns the problem
and solution is essential in order to be successful.
Number 2:
Rank your
key assets based on risk. Risk can mean many things to many
people. Develop a small list of questions to develop your
ranking of assets. One question may be: “If this asset were to
stop would it stop plant capacity?” or “if this asset stops an
outage of longer than 24 hours what will occur?
NUMBER 3:
Begin writing work orders for all emergency and preventive
maintenance work on priority 1 and 2 assets based on your
ranking of assets above. Ensure accurate labor hours are added
to each. Track and trend these hours against each other and post
the results after 4 weeks. Ask a team of operators and
maintenance personnel to make recommended changes to the PM
program on worst performing assets as a result. See example
graph below.

NUMBER 4:
Restore, one step at a time, your highest risk asset in worst
condition and at the same time develop operator and maintenance
preventive maintenance procedures. These procedures should
include steps (yes, step by step), specifications, parts
(filters with storeroom number), permits required, estimated
time required to complete, etc.
NUMBER 5:
Once the asset is restored
and a repair has been made then a corrective maintenance
procedure must be written with specifications, steps, estimated
labor hours, drawings, special tools, etc. identified.
Number
6:
Use the new Preventive Maintenance (PM) procedures on the newly
restored asset. Apply the 10% Rule of Preventive Maintenance.
This rule is defined as a PM that must be completed within 10%
of the time standard. Example: if the PM requires to be
accomplished every 30 days then it must be completed within 3
days or it is out of compliance. The expected goal is 100%
compliance. It may not start out this way but should end up this
way.
Number 7:
Fabricate a
sign that states “Warning, This Equipment is Maintainable,
Only Proactive Maintenance in this Area ”, See the example
below. Only allow your best maintenance personnel and operators
to work in this area.

NUMBER 8:
Develop Overall Equipment Effectiveness metrics for the
production area. If you don’t know how to make this happen just
send me an email and I will help. Post the daily and shift OEE
on a line graph and show the trend. Leadership needs to back off
and let the operators and maintenance personnel do their job and
lead this effort.
OEE =
Equipment Availability x Performance Efficiency x First Pass
Quality with
World-class levels of OEE start at 85% based on the following
values:
90% Equipment Availability x 95% Performance Efficiency x 99%
Rate of Quality = OEE of 84.6%
The OEE
calculation factors in the major losses it seeks to eliminate.
The first focus should be on major equipment effectiveness
losses, because this is where the largest gains can be realized
in the shortest time.
There
are 11 major areas of loss, and they fall within four broad
categories:
Equipment Availability:
Planned-shutdown losses
1.
No
production, breaks, and/or shift changes
2.
Planned
maintenance Downtime Losses
3.
Equipment failure or breakdowns
Setups
and changeovers
4.
Tooling
or part changes
5.
Start-up and adjustment
Performance Efficiency:
Performance efficiency losses
6.
Minor
stops (less than six minutes)
7.
Reduced speed or cycle time
First Pass Quality
(Yes, First Pass Quality ONLY)
Quality
Losses
9.
Scrap
product/output
10.
Defects
or rework
11.
Yield
or process transition losses
NUMBER 9:
Develop a vendor performance metric. This metric will have three
parts. One, the percentage of time a vendor delivers a part on
"the agreed upon time" (one minute late is late, sorry); two,
the percentage of time the same vendor delivers the wrong part
(no substitution unless agreed upon by maintenance manager);
three, the times the same vendor delivers the wrong quantity of
parts. The sum of these three measurements equals the vendor
performance metric. Post this metric by vendor by month in the
storeroom. The standard should be 95%, sorry no excuses
accepted.
NUMBER 10:
Now take the assessment
results from
Terry Wireman’s book and work on the maintenance process
beginning with the planning and scheduling process first.

training suggestions, send me an email at

good luck.
