Maximising Capital Returns Requires Real Time Thinking!
How do companies maximise their capital returns and
supercharge their production efficiency programmes? The
philosophies and approaches of Lean and Sigma are driving
industry forward but how can we accelerate the journey of
continuous improvement? Lean Sigma techniques need to be fully
integrated and imbued into the very fabric of an organisation
and hard wired into all of its processes. We need more than just
Lean thinking; we need to have real time thinking and
performance.
The next revolution and frontier for production efficiency is
the movement to real time. Therefore to maximise capital returns
on production investment you not only have to
"Think Lean"
but essentially you have to think and work in
"Real Time".
"Real Time Thinking" provides instant knowledge and the
potential for instant reaction or intervention.
There are 12 principles which make "Real Time Thinking"
essential for maximising return on investment. Real time
production efficiency represents a new frontier in production
efficiency improvement techniques. The 12 principles of Real
Time are:
Data Quality ….
Manual Collection Looses Integrity ….
Immediacy Brings Integrity ….
Immediacy Brings Intervention ….
Avoids Personal Agendas ….
Comprehensive Set of Measurements ….
Real Time Makes Things Visible ….
Real Time Analysis ….
Visual Re-enforcements ….
Accelerates Culture Change ….
Connectivity To Customer & Supply Chain ….
Real Time Performance Focus ….
Data Quality ….
The quality of data collection and real time analysis is key
to driving up production efficiency. The quality, integrity and
immediacy of data are often overlooked and frequently
misunderstood. If the data set has weaknesses then no matter
what analysis is performed, the outcomes are going to be less
than satisfactory. Data collected historically, say at the end
of a shift by the operator filling in a form, is limited in its
consistency, accuracy and reliability. Such data allows false
pictures to form with inaccurate and therefore ineffective
analysis of the actual performance of a manufacturing cell and
an inaccurate Overall Equipment Efficiency (OEE) value being
conveyed.
The plain truth is that any cell or manufacturing unit
claiming world class levels of OEE of say 80% plus, who are
using manual, historical and batch analysis and methods are
almost definitely fooling themselves. The process is likely to
be riddled with problems of over estimation of the positive,
papering over the cracks with highly inaccurate actual
performance.
Manual Collection Looses Integrity ….
For many manufacturers, allegedly accurate data from the
factory floor is collected manually with reporting through
spread-sheets via respective computer terminals. Much of this
data may be entered into the system 8 to 48 hours after
execution and can be subjective and inaccurate. The supply chain
or other supporting streams use data that is neither timely nor
accurate. This inaccuracy and variability of shop floor data
affects the company’s ability to react to changes in product
throughput or customer demand.
Immediacy Brings Integrity .…
The immediacy of real time data monitoring is very powerful
at removing basic delays and negative inertia. Historical and
subjective monitoring of any production related data is like
looking in a cars rear view mirror; it is not immediate and does
not enable direct intervention when the problem occurs - leaving
a missed opportunity. As the saying goes my aunt has never been
in many accidents but sees a lot in her rear view mirror! She
assumes that her driving is fine and does not focus on the real
problem.
When the report eventually finds itself on the production
managers desk, it may get read that day, maybe that week. More
often than not there will be other crises to deal with, board
reports to do, supplier problems, staffing and so on. All the
daily management responsibilities get in the way avoiding
intervention and missed opportunities for efficiency
improvement. Real-Time is immediate, action orientated and is
impactful.
Immediacy Brings Intervention ….
To really accelerate the Lean journey operators and
supervisors need up-to-the minute information in order to
optimize production. Real Time OEE (Overall Equipment
Effectiveness) monitors how machines, production lines or
processes are performing in terms of Availability, Speed
(Performance) and Quality to provide accurate performance
information.
It is estimated that plants still waste up to 40% of their
productivity through
unplanned stops and interruptions, speed losses and quality
defects. If this information is made available in real time then
the operator, the supervisor, the production manager or
maintenance manager can intervene immediately with instant
impact on waste and production efficiency.
Avoids Personal Agendas ….
Everyone wants to be a winner, so … people will select the
measurement criteria that suits the environment and historical
working practices. This creates a subjective reporting
environment which rarely identifies the true causes of waste and
inefficiency. The measurement criteria will naturally follow
those criteria suited to batch, historical and subjective means,
hence inappropriate for the job at hand. Complex readings and
variables that impact quality, the speed of the machine and
rejects will be missed. In the collection of data memory
interpretation is relied upon which is tainted by personal
incentive and team pressures. This is only natural.
So what can be done? The solution is to collect, monitor and
analyse data real time. Real time automatic data capture enables
the right data to be collected at the right time with accuracy
and without subjectiveness. Real time will provide a
comprehensive set of variables and provide a more insightful
reflection of the production process by providing the accurate
OEE performance of your assets employed.
Comprehensive Set of Measurements ….
Lean Sigma and other continuous improvement programmes often
start with the basics being monitored, which is ideal for
getting simple buy in and engagement of all the people involved.
This initiates the cultural change and learning curve for all
team members. It is something to build upon and get some readily
understood quick wins. However this approach is often supported
with blind investments in quality control education and lean
philosophies without measuring the actual outputs.
This strategy will provide some improvement, however this in
no way will provide the means to maximise asset implementation
as there is no reasonable way of evaluating return on
investment. Whether or not you have better qualified and trained
staff if they do not have improvement targets with measurable
outcomes this will lead to a lack of focus and sub optimal
performance. This way of thinking, is no way to "maximise" your
production efficiency programmes.
What is needed is a more comprehensive set of measurements
that does focus the effort in the right place. If you do not
measure something then you will miss it and you will be loosing
the ability to focus and improve. When you hard wire real time
data analysis it forces you before you install to think of your
data collection strategy. When implementing Real Time data
collection a specific strategy has to be considered. In that
process the full impact on the organisation and therefore a
comprehensive set of measurements have to be considered and
implemented. This strategy will need to incorporate a scaleable
implementation plan as the results of the findings will
inevitably bring operational and cultural change. What is the
most comprehensive set of measurements that can give me the full
picture of the production process and measure the true OEE of a
cell or a line?
An even more obvious miss will be the question of what data
do I need to measure that can be used or passed on the other
parts of the production process in-house or even to another part
of the value chain outside of your organisation? This may be
something that is valuable for the supply chain or it may be
something that is value to the demand chain where the greater
savings may be made.
Make Things Visible ….
If you can’t see it you can’t fix it! Only when something is
measured can it be analysed and acted upon.
"When you can measure
what you are speaking about
and express it in numbers,
you know something about it;
when you cannot measure it...
your knowledge is meager
and unsatisfactory."
----Lord Kelvin
Historical and batch analysis can often hide itself under a
pile of papers on the production managers desk, real time brings
the data to life. Visibility is integral to real time
monitoring; real time sharpens the insight and the understanding
of the real issues. A lot of production efficiency issues are
solved with a matter of common sense rather than become masked
under a cloud of other extraneous issues and criteria given
credence through batch and historical analysis.
Visual Re-enforcements ….
Leading real time monitoring systems such as ABB’s RealTPI
are able to provide instant visual communication and are
flexible enough to be able to provide this in a wide range of
outputs. This means that visual aids can be developed
differently and tailored for each target audience in the
production team from the operator right through to the board
room.
All these elements help to accelerate the maturity of the
culture and behaviour of all the stakeholders in the production
value chain.
By using real time intervention as opposed to historical
analysis techniques Dow Corning in Belgium were able to save 8%
on their production costs. While at the same time increasing
availability, production speed and output quality of the
equipment, over a period of three years, Dow Corning was able to
gain one entire month of production.
"Real time automatic analysis and intervention has enabled us
to identify problems much quicker and to focus on real
priorities." concluded Ronald Hupin of Dow Corning.
A Leading Pharmaceutical company has used Real Time with
tangible success.
Speed losses in vital filling process resulted in
lost product
Historically, filling process is difficult process to
determine losses
Real-TPI captured on-line machine data and analysed
causes of losses
Resulted in the elimination of bottlenecks, target of
monthly maintenance activities, and the report KPIs to
management
Payback in the first two production hours saved!!
Real time visibility can be provided to suit the user or
organisation, by various methods, via mobile phones, pagers,
handheld terminals, board room computers, flat screen notice
boards and various types of operator information panels.
Real Time Analysis ….
Real time analysis to set criteria can short circuit to
planned interventions and accelerated solutions to waste,
bottlenecks and inefficient practises.
Real Time data provides the facility for analytical processes
to be carried out in line. This capability provides OEE, Route
Cause Analysis (RCA) and accurate Total Preventative Maintenance
(TPM) activities to be applied to the production environment.
All of these can be implemented with the additional benefit of
automatic real time reporting replacing subjective manual
reporting scenarios.
When OEE indicates poor plant performance, RCA is utilized to
determine what the problem is and where it is located so the
corrective action can be taken. TPM is a process to adjust
production equipment procedures with the aim of improving
efficiency. It eliminates inaccurate, inconsistent, defective,
and laborious manual logs.
Real Time provides the facility for RCA to be carried out
with accurate tuning and event log management, creating an
objective blame free view to be taken in resolving problems that
are reported upon.
Dynamic PARETO charts can report the cumulative breakdowns by
category, type and/or machine during the selected time period.
It can provide the ratios between the different causes of
breakdowns in the line and classify them in descending order by
cumulative time. For each breakdown PARETO charts can show
cumulative time and number of breakdowns, as well as percentages
of the category and of the total time period. Chronograms can
then identify the state of the machine and provide reasons for
machine stoppages (i.e. planned downtime or breakdown) during a
sequence of events.
When real time data collection is implemented it provides an
accurate recording of the "Actual" data and not something that
may or may not have occurred in the past. Therefore if this
information is used in TPM systems a precise diagnosis real time
and against trends can bring step function improvements in
production output and efficiency through more up time and
reduced unplanned stoppages.
The obvious advantage employing Real Time is that the OEE of
the operation can be calculated as a true accurate figure. This
figure will enable the enterprise to calculate the true ROI on
the employed assets. The OEE figure also provides the true
capacity of the assets that are currently employed giving clear
insight to forward investment requirements.
With this level of analytical power, real time feedback
allows corrective action to be taken in shorter periods of time,
thereby increasing OEE. This will develop a better understanding
of the production potential of existing plant equipment and
accelerate the journey of continuous improvement in real time.
Accelerate Culture Change ….
Real time intervention can also have a dramatic effect on the
rate of change of less tangible but crucial elements of the
production process. It is the immediacy, transparency and
integrity of real time monitoring information that can impact
the production team’s perception and behaviour.
Continuous improvement is a journey but it is the rate of
culture change and speed of improvement that is the key to
success and often even the very survival of a business or
production unit.
Real time also brings stability and consistency to the
management of efficiency improvements. It gives the overall
programme the gravitas and credibility of the objective data
that is provided.
Result setting is a closed loop. Once set they cannot be
miss-used or ignored. The beauty of real time is that you have
to think of all aspects of the data and then hard wire them into
your operation.
You can even set parameters of performance and "what ifs"
with pre-determined and automatic interventions. This could be
an instant stoppage, an instant communication to the production
management and directors, an instant visual aid to the operator
or an automatic communication to another part of the production
value chain. When this is carried out automatically along with
an with instant execution of the remedy you obtain instant
benefit.
The opportunity for saving is as perishable as an aircraft
seat to an airline, once the aircraft doors are shut the revenue
from that empty seat is lost for ever and this is the case with
many opportunities to save costs. Instant action provides
instant efficiency savings through closed loop decision-making.
A real time DMAIC (Design Measure Analyse, Improve, Control)
will accelerate the rate of change and improvement and will
increase the rate and quality of connectivity through the total
value chain.
Over 20 years ago it took an engineer a quarter of a year to
do a Design of Experiments manually, now with automated
analytical tools a number of tasks can be carried out in a day.
Moving to real time monitoring can increase this exponentially
with the results and influence spreading rapidly across the
internal team and other partners in the total production value
chain.
Connectivity To Customer & Supply Chain ….
Most manufacturing companies have implemented software
programs and procedures to monitor and optimise its supply
chain. These programs are designed to reduce raw material
(inventory), work in progress, and finished goods inventory.
To be successful, and in some cases survive, manufacturing
companies require real-time data from the factory floor that
reports on quantity of raw materials used, yields, scrap rate,
and production output. This data allows the company to know the
current status of all of its production orders so it can meet
the needs of its customers. Having this information available in
real time allows timely and accurate communication of this
crucial information.
Real time data can be used elsewhere for connecting to the
demand chain. Changes in demand patterns, flexibility in design
and other innovations are possible when you have real time data.
A more informed production value chain becomes a more flexible
production value chain and therefore more able to adopt to ever
changing customer needs.
Real Time Performance Focus .…
Manufacturing companies are constantly striving to improve
performance by increasing output and yield while reducing
operating costs. These companies traditionally have made large
investments in capital equipment to meet the demand of the
market place. The operation of these assets must be optimised so
they can maximise returns on the capital employed.
Real time is not quality management for the sake of it. It
represents the principle that you should always focus on
specifics and projects that maximise their ROI against tangible
measured results. Real Time provides more certainty and has
immediate impact on production efficiency and ROI for assets
employed.
The importance of optimising return on assets is seen in all
manufacturing companies across the spectrum of manufacturing
industries.
Shareholder value is directly affected by the company’s
stockholders and analysts’ assessment in evaluating the future
performance of these companies, as they are looking to
accurately value their return on investment. Improving the
performance of the company’s
existing assets
to improve financial performance is key to improved shareholder
value in a reducing market place, here in the UK.
It is estimated that plants still waste up to 40% of their
productivity through unplanned stops and interruptions, speed
losses and quality defects. In today’s fast paced, collaborative
business world, this loss of value can be the difference between
a company’s success and failure.
Summary .…
The next revolution and frontier for production efficiency is
the movement to real time. Therefore to maximise capital returns
on production investment you not only have to
"Think Lean"
but essentially you have to think and work in
"Real Time".
