My Machine Concept – Individual Ownership of
Equipment(s) / Area(s) defined
Leadership through Innovation
PSPD
 The early years of the initiative concentrated on bringing the equipment back
to its basic original condition by:
 Attacking forced deterioration – Ensuring basic machine hygiene
 Correcting design weaknesses from the time of installation
 This was achieved by bringing in Ownership or “My Machine” concept
(included both Operators and Maintenance crew)
 Implementation of CLTI checklist
 Checkpoints to assess the health of the equipment when it is in the running
condition using the 3 basic human senses
 The Equipment owners in turn report deviations found (if any)
 This has given enough inputs in-time to carry out the PM Schedules more
effectively.

A 10 Step Approach of implementation
Leadership through Innovation
PSPD
 Knowledge enhancement of JH members who learn in detail about the
function of their equipment in the entire process, equipment construction and
working principles
 Skill enhancement of JH members
 To support JH members to carry out simple abnormality rectification on their
own.
 Understanding the importance of their daily CLTI checks and identify the
impact it has on the health of the equipment.
 To identify and correct quality related issues immediately
 Prediction of possible failures to avoid breakdowns
 Creation of trainers within the JH teams who can transfer knowledge.
PS: This is a hands on learning exercise and the JH members are involved at every
step by getting support from DMT members and participate in live dismantling /
assembly of equipments as far as possible.

10 Steps of ESFC:
1. Identification of Basic Machine Elements
2. Preparation of Training Packs& On-Job Training Curriculum
3. Creation of Equipment System Flow Chart
a) Process Flow Diagram
b) Equipment System Flow Diagram
4. Creation of Schematic Diagram
5. Identification of items for mapping problems
a) Identification of Parts List
b) Identification of Overall Inspection Items
6. Creation of Part-Problem Matrix
7. Creation of Inspection Checklist
8. Preparation of Know-Why Sheets
9. Creation of Inspection Manual
10. Training of Workforce

:
It is used to identify the various machine elements that JH members will be trained on
and also the major parts that will be depicted on the Process Flow diagram & Equipment
system flow diagram respectively.
Machine elements will help in identification of subjects for training packs and help
employees in understanding the various parts in their respective equipments

Pack preparation and OJT curriculum designing was a step in which training materials / content were
prepared in-house (based on our belief that internal faculty and training pack creators are better positioned to
understand the needs and can customize training contents to suit the technical needs of the in-house
recipients)based on the machine elements identified in Step 1. These packs were prepared for training the JH
members on basic machine concepts.

A) Process Flow Diagram
Creation of Process Flow diagram involved logically interlinking all the processes
in a particular JH to facilitate easy understanding of the Overall Process.
Leadership through Innovation
PSPD
B) Equipment System Flow Diagram
This step firstly involved splitting the Process Flow diagram into logical sub-processes. Each
sub-process was then depicted on a separate chart interlinking all the equipment. The energy
flow in the sub-process was depicted here and therefore the internals of the equipment were
shown in this case.

Preparation of process flow charts and identification parts list
by JH members
Leadership through Innovation
PSPD
The step intended to give a detailed knowledge of parts of the equipment to JH
members. This involved dismantling the equipment where ever possible.
Leadership through Innovation
PSPD
Identification of Parts list helped the JH team members to understand the various
components that constitute the whole equipment.
Leadership through Innovation
PSPD
This step involved collation of all checklists pertaining to the equipment (i.e. Condition
Appraisal/PM task list/Condition Monitoring/CLTI) into a single consolidated sheet.
This list was compared later with a part-problem matrix (post Step 6) to know the
missing checkpoints and JH members would subsequently update it at a later stage.
Leadership through Innovation
PSPD
This step involved mapping of equipment parts to the possible failure modes (problems) of the
sub-equipment.
The output of this exercise was a part-problem matrix (mentioned in Step 5 B) which was used
by JH teams to compare and update their current checklists.
This also ensured standardization of checklists for similar equipment across the mill.

 This step involved the collation of the outputs of Step 1-8 into a single manual
at the equipment level
 It is a live document with Why-Whys and OPLs (One Point Lessons) being
added as and when they are made.
 It helped in the training the JH member (existing Equipment owner) on a
particular equipment and also acted as a ready reckoner for his successor in the
event that the ownership was transferred.
 Also, unlike an OEM equipment manual which is cumbersome to refer to
especially by the employees who may not be having a formal background, as this
entire ESFC is done as a hands on exercise by the employees, ease of
accessing and connecting to the field equipment is far more easier.

 After involving shop floor person (JH member) who is an owner of a equipment,
once he has gone through the entire exercise of ESFC (from Step-1 to Step-10),
he is able to understand the importance of each part
• its working principle
• And possible ways in which it can fail.
 This knowledge has enabled the process operator to operate the equipment
under standard condition, resulting in,
• less wear and tear of parts
• Improved understanding of engineering crew member on the importance of
the equipment health condition for good quality product
• The entire experience of the exercise was appreciated by the workforce
especially the ones who did not have any formal training in the past. .
Leadership through Innovation
PSPD
Post mill-wide training using the ESFC concepts substantial benefits where observed
in terms of Maintenance and Quality KPI improvement.
 Increase in Kaizen Generation due to better awareness of equipments.
 Improvement in Skill Index of JH members due to better understanding of
phenomena.
 Break downs reduced due to improvement of knowledge on equipments.
 Developed trainers internally to train JH members.

Occurrence: Three per year
Analysis: During why-why analysis
reasons could not be found and anvil
fixing bolts replaced during every
breakdown. Even after changing the bolts
failure repeated.
While preparation part problem matrix
one it was understood from manuals that
weight of hammer is important with
respect to anvil fixing bolts design.
Action initiated: Replaced with right
weight hammers and OPL made to avoid
future mistake
Benefits: Lime kiln down time reduced
