Case Study<br />
Now that you have a good understanding<br />
of each of <strong>the</strong> 6 Steps Beyond <strong>the</strong> 5 Why’s,<br />
let’s refer back to <strong>the</strong> initial case study<br />
used to illustrate <strong>the</strong> 5 Why method and<br />
how diving deeper <strong>beyond</strong> this method,<br />
using <strong>the</strong> “6 <strong>steps</strong>”, can allow you to get to<br />
<strong>the</strong> root causes of a problem.<br />
If we were to initiate <strong>the</strong> “6 Steps”, a<br />
search for all relevant information would<br />
be undertaken. Statements, photographs<br />
and a search for all maintenance history<br />
on <strong>the</strong> drive motor are all collected.<br />
(Step 1)<br />
The RCA is <strong>the</strong>n undertaken (Step 3).<br />
Clarification of <strong>the</strong> purpose of <strong>the</strong><br />
investigation, in this case preventing <strong>the</strong><br />
recurrence of <strong>the</strong> “Delay in loading <strong>the</strong><br />
train”, is <strong>the</strong> first step. Then context to<br />
<strong>the</strong> problem is included by identifying<br />
“When” it occurred, “Where” it happened<br />
and how “Significant” <strong>the</strong> problem is (for<br />
example; damage to reputation, cost of<br />
any demurrage for delayed shipments<br />
etc). Quantifying <strong>the</strong> costs will create an<br />
understanding of just how significant this<br />
problem is.<br />
With management’s support, key<br />
personnel have been identified to<br />
participate in <strong>the</strong> investigation and invited<br />
to attend. An experienced facilitator has<br />
been appointed based on <strong>the</strong>ir ability to<br />
handle all <strong>the</strong> individuals in <strong>the</strong> group and<br />
to control <strong>the</strong> (potentially large) group<br />
size.<br />
The room that has been booked is suited<br />
for <strong>the</strong> size of <strong>the</strong> group and <strong>the</strong> facilities<br />
allow for <strong>the</strong> recording and organisation of<br />
large amounts of information. The more<br />
room <strong>the</strong>re is <strong>the</strong> better as it allows <strong>the</strong><br />
facilitator to spread <strong>the</strong> information out in<br />
logical paths to make it easy for o<strong>the</strong>rs to<br />
follow. The facilitator can <strong>the</strong>n separate<br />
cause paths and cater for <strong>the</strong> expansion of<br />
<strong>the</strong>m. (Step 2)
