W8_LUCKY_DETERMINING ROOT
CAUSE(S) OF POOR ON TIME DELIVERY PERFORMANCE
1.
Problem
Recognition, Definition, Root Cause Analysis and Evaluation
(i)
Problem Recognition
At a recent Supplier Delivery
Performance Workshop, the subject firm was presented with a 36 per cent score
in line with the scoring formula for on time delivery against a total of 464
Purchase Order line items awarded to the firm. The scoring is quite low
compared to other competing firms who scored 75% and 95% respectively for
purchase order line items of over 1000.
(ii)
Problem Definition
The score of 36 per cent is
poor and is symptomatic of underlying cause(s) that need fixing for the company
to remain in business.
Using CAWTOE[i] methodology for a better
understanding of the issue exploring the various perspectives, we have
C – Customer’s Perspective:
The customer is not pleased with the performance the reason they made public
the rating
A – People (Actors): The
employees are unaware of this big picture as most of them feel they work too
hard
T- Transformation Process:
All employees in the procurement department have undergone ACCPAC training (the
procurement software used in the department) and a majority of them are
proficient in its use.
W- World View: The on time
delivery performance metrics for Best in Class and Industry Average companies
is 81.8% and 76.6% respectively[ii]
O - Process Owner:
Sales/Procurement department managers are equally not impressed with the
results.
E – Environmental
Constraints: The parts are imported from the OEM overseas either by air or sea
freight which takes between 6 – 8 weeks in the minimum and sometimes longer to
arrive Nigeria. Custom clearing takes between 1 -4 weeks depending on the
category of goods.
(iii)
Root Cause Analysis and Evaluation
The purpose is to figure out
why this problem occurred. I am using the popular Root Cause Analysis to do
this. The methodology is based on the premise that systems and events are
interrelated such that an action in one area triggers an action in another area
and so on. Thus it is possible to trace back those actions to the starting
point as reasonably acceptable.
I will follow the five step
process[iii] of define the problem, collect data, identify
possible causal factors, identify the root cause(s), and recommend and
implement solutions
2.
Development of feasible alternatives (Causal factors)
There are three basic types
of causes comprising of Physical causes (tangible material failure), Human
causes (People did or did not do something) and Organizational causes (Faulty
System/process or policy).
Using the 5 Whys [iv] approach:
Sequence of events leading to
the problem:-
Consistent late delivery of
Purchase Order line items (Physical Cause, Human
causes and Organizational causes)
Consistent late receipt of
goods from overseas (Physical Cause, Human causes
and Organizational causes)
Consistent late placement of
order (Physical Cause, Human causes and
Organizational causes)
Late pick up of Purchase
Order (Physical Cause, Human causes and
Organizational causes)
Infrequent
check for available Purchase Order with the customer procurement department (Physical Cause, Human causes and
Organizational causes)
3.
Development of outcomes for each alternative (causal
factor)
The outcomes for each causal
factor alternative are as follows:
Using the 5 Whys approach
1.
Consistent
late delivery of Purchase Order line items (Physical
Cause, Human causes and Organizational causes)
2.
Consistent
late receipt of goods from overseas (Physical
Cause, Human causes and Organizational causes)
3.
Consistent
late placement of order (Physical Cause, Human
causes and Organizational causes)
4.
Late pick up
of Purchase Order (Physical Cause, Human causes and
Organizational causes)
5.
Infrequent
check for available Purchase Order with the customer procurement department (Physical Cause, Human causes and Organizational causes)
4. Selection Criteria causal factors
The selection criteria are as
follows:
1.
Short
time to implement solution
2.
Implementation
impact level
3.
Minimal Cost
(within budget)
5.
Analysis and Comparison of the alternatives (causal
factors)
Attempting to use the non-compensatory
model of satisficing[v]
to narrow down a causal factor,

Satisficing (By Author)
6.
Selection of preferred alternative (causal factor)
Comparing the attributes
values against the feasible range reveals that addressing the infrequent check for available Purchase Order
with the customer procurement department promises to provide the quickest
solution at solving the problem of late on time delivery performance.
Incidentally, this aligns with what the Root Cause Analysis reveals as this causal factor lies at the root of the problem.
7.
Performance monitoring and post evaluation of results
I would need to address the
lack of know-how by proposing training for all procurement personnel in basic
business management skills including basic project management skills, and
monitor and evaluate the results six months down line.

Awesome, Lucky!!!
ReplyDeleteNice case study of on time delivery from a supplier or vendor......
How about this for your next posting- now that you have done the root cause analyis, turn to pages 122-135 in your Memory Jogger 2 and apply Pareto Analysis to the same case study. Compare which tool/technique results in the most effective way to not only identify a problem but help measure it. (HINT: For step 7, you will find Pareto Analysis does a better job- see page 128 in MJ2)
And your citations are spot on....
Keep up the good job, and looking forward to see your compare the use of RCA combined with Multi-attribute decision making vs RCA then applying Pareto Analysis.

Dr. PDG,
ReplyDeleteThanks for the comment and steer. I will refer to the suggested pages in the MJ2 and apply Pareto Analysis to the same case study and then identify which tool/technique beteen RCA and Pareto Analysis not only identify the problem but better measure it. Then step 7 - of same blog, compare the use of RCA combined withMult-Attribute Decision making versus RCA then applying Pareto Analysis. Can I do this for my W10 blog posting? I already had worked out solutions for my W9 blogs.

Lucky
