Have you tried to lean your IT Service Management? by Daniel Breston

LEAN IN ITSM
A FUNNY THING HAPPENED ON
MY JOURNEY

FRAME THE SESSION
• What normally happens Is we build a process from
left to right
• Why?
• What if we built the process starting with the
customer?
• Define customer as user, external customer, next in
line, I don’t give a toss.
• Vision, SIPOC, VSM with post-it notes, all players in
one room for a day
• Take no prisioners, assign RACI afterwards
• KPIs: if they don’t enable a decision they are a
metric

SET THE FOCUS
S I P O C
Supplier Input Process Output Customer
Who provides
information?
How is this
turned into
requirements
or wishes?
What are the
steps?
What is the
outcome?
Who receives
the outcome?
SIPOC: a simple way to scope a process

VALUE STREAM MAPPING
 Value Stream Map is a
detailed process flow
diagram of the current
value stream.
 The aim of Value Stream
Mapping is to visualize a
process in such a way
that the process can be
analysed
 Take the SIPOC and
create a detailed flow of
process steps
Process nameInput of the process Output of the process
Step 1 Step 2 Step 3 Step 4 Step 5

VALUE STREAM MAPPING: TAKT TIME
 Takt time determines the
correct pace of the
process to ensure that it
delivers products to match
customer demand
 Takt time is calculated by
dividing the net working
time available by the
number of customer
requests
 If the output of the process
is lower than the Takt time
then the customers will
have to wait
Unit of work: Change
Takt time: 6 hours
CUSTOMERS:

VALUE STREAM MAPPING: BASIC INFORMATION
 Add basic information
such as the input and
output.
 Subdivide the process
into steps that can be
measured
 Describe the steps

NOW I CAN IMPROVE
Time metrics are added to
the VSM
 Cycle Time: time spent
to create the product.
This is value-added
time.
 Waiting Time: time
spent on waiting for the
next activity.
 Standard Time: the
time that a particular
step should take to carry
out.
 Process Cycle
Efficiency: (PCE) is the
degree of efficiency of a
process.
Takt time: 6 hours
Lead time: 20 days

VALUE STREAM MAPPING: UNITS OF WORK
 Add the type of unit of
work that gets processed
by this process
 Record the customer, as
previously defined in the
SIPOC
 Specifically define the
amount of work from each
customer if there is more
than one customer

VALUE STREAM MAPPING: LEAD TIME
 Lead time: time between
the moment a customer
requested something and
the moment that it was
delivered
 Calculation of Lead time:
Lead time = Time the
customer received the
requested performance –
Time the request was
submitted
 The lead time depends on
work-in-progress and how
many products are
delivered on average in a
given time
 Shortening lead time often
goes hand-in-hand with
the reduction of the work-
in-progress
Takt time: 6 hours
Lead time: 20 days

VALUE STREAM MAPPING: STANDARD TIME
 Standard time is the time
that a particular step
should take to carry out.
 Standard time is not
necessarily the same as
the actual time spent.
 Times are always
recorded in minutes
 Determine per step how
long the step should take.
 Record in the block in the
step.
 The total of the standard
times is the standard time
for the entire process.
Takt time: 6 hours
Lead time: 20 days

EFFICIENCY OF TIME-USAGE IN PROCESSES
 Process Cycle Efficiency
 Time-based measurement
 Helps to identify whether a process is approaching flow
 Process Cycle Efficiency = (Value-added Time / Lead Time)
 The closer the PCE is to 1 (or 100%) the greater the flow

Effort
• Roles & responsibilities
• Elicit a response
• Top down
• Limit the number
• Make them agreed

(approved and unauthorised)
Percentage of assets/configurations updated along the the path
Number of “special” change requests (those Management decrees)
% of effort across the lifecycle
