In this week’s episode, we inform Marie about the principal deviations in her logistics process. As such, Marie can fine-tune her business process based on actual data.

What preceded…
Marie, CEO of SmartCoat Inc., asked us to analyze and make
recommendations for the logistics process via process mining and data
analytics techniques ... Just by looking at the data in SmartCoat’s ERP
system!
In the previous episode, the logistics process of her company has been
discovered and visualized. The most frequent paths (variants) have been
discussed.

Cédric, your horsum guide
Hi, good to see you’re back!
In the first episode, Marie told us about some SmartCoat checks
and tests she requires to be executed in this logistics process.
In this episode, I will verify if these checks and tests have been
performed correctly. I will also give Marie some feedback.
I will perform the process mining analyses in this episode with the
process mining software Disco.

Checks and tests
Do you remember what checks and tests Marie told us about?
No? Let me help you…
1. All smartphones need to be checked upon arrival to verify if they
are both fully operational and not damaged.
2. All coated smartphones need to be tested. For the smartphones of
customer Wallsmart, an additional third test is required.
3. In case a smartphone fails for a test, scrapping should be proposed
and evaluated by Marie.

Checks and tests
In the following slides, I will analyze whether the right
checks and tests have been correctly executed.

1. All smartphones need to be checked upon arrival
On the right, I see that 35 uncoated smartphones
are received. Five of them are not checked at all:
they are immediately stored ... On the next slide, I
will further analyze who forgot to perform these
checks.
Analysis | Examine whether all smartphones are checked twice upon arrival: operation check and damage check.

1. All smartphones need to be checked upon arrival
In the table on the right, I
see that Arthur did not
perform the required
checks. I think we should
talk to him …

2. All coated smartphones need to be tested
Analysis | Examine whether all coated smartphones have been tested twice: test 1 and
test 2. Next, examine whether test 3 has been performed for all coated smartphones of
customer Wallsmart.
First of all, I’m analyzing whether ‘test 1’ and ‘test 2’
are performed before the smartphones are shipped …
This is what we should be sure about … No shipments
with lacking tests! That is why I only select
smartphones who passed activity ‘ship coated’. On the
right, I see that 27 smartphones are shipped. After
some investigation, I conclude that ‘test 1’ and ‘test 2’
are done for all shipped smartphones. I also see this on
the process map: ‘test 1’ is performed 27 times and
‘test 2’ even 28 times. Does the latter mean that ‘test
2’ has been done twice for a smartphone? Indeed,
after further investigation, we note that Phone 3666 is
tested twice.
I also note that ‘test 3’ is executed 8 times. I wonder
whether these smartphones are related to Wallsmart …

2. All coated smartphones need to be tested
To analyze this, I only select the shipped Wallsmart
smartphones in the process mining software … I see that 8
smartphones are shipped. I also see that ‘test 3’ has been
performed 8 times … So far so good … But it is strange that
there is one arrow that starts at ‘test 1’ and directly goes to
activity ‘ship coated’. Does this mean that ‘test 3’ was not
performed? Let’s examine …

2. All coated smartphones need to be tested
On the right, the path of this particular smartphone is
shown. I note that ‘test 3’ is performed, although not in
the order I expected … Let’s ask Marie for the reason of
the unusual flow and whether a specific order is
required.

3. Failed tests result in proposals to scrap
Analysis | Examine whether proposed scrapping is evaluated by Marie in case a smartphone fails for a test.
In the process map, we see that 6 smartphones are
proposed to be scrapped: 4 after ‘test 1’ and 2 after ‘test 2’.
We also note that all 6 proposals have been evaluated. One
of them is stored again. This indicates that the proposal was
refused. In the event log, we see that all proposed scraps
are evaluated by Marie. Good job!

Feedback Hi Marie, I have analyzed whether all inbound checks and coating
tests are performed. I have discovered some irregularities. Let’s run
through them …
Arthur, the warehouse assistant, has not always performed the
required inbound controls. Let’s talk to him … Maybe he has good
reasons for it. Nevertheless, I suggest to have a short meeting with the
warehouse team and to stress the importance of the inbound
controls.
Based on the process mining analyses, I also noted that the required
tests are done after coating. Sometimes, they are not always done in
the order I expected. I found a case for which ‘test 2’ was done before
‘test 1’. Does it matter? Is there a specific reason for it? I also found a
case for which ‘test 2’ was done twice.
I also checked whether smartphones are sometimes scrapped without
your evaluation … Well, based on my analysis performed, you have
evaluated each scrapped smartphone. Good job!

improvement opportunities Cédric will identify via
