When searching for software systems, manufacturers carry around a
large catalogue of requirements as well as the perception that they
can’t ALL possibility be met.
While they are smart
enough to realize that there is no one solution, some lag behind in
implementing some of the software that is available, and need to grasp
what these tools can bring to their companies, which include:
• Better tracking of key performance indicators;
• Real-time monitoring of system and production performance;
• Real-time visibility into supplier performance and product availability;
• Simulation of production and plant processes to avoid bottlenecks, constraints;
• What-if scenarios to help with production planning and scheduling;
• Event exception alarms and sensors that trigger actions when
performance parameters or machines get out of specification; and
• Predictive maintenance capacity to avoid unscheduled downtime.
Understandably, while there is no one complete software package that
can comprehensively meet every item on this wish list, progress is
being made.
Analytical view
According
to Alison Smith, senior research analyst with Boston, Mass.-based AMR
Research Inc., the problem is that even though manufacturers know they
need to do a better job embracing software technologies, it is usually
unclear where the actual problems exist.
“There is
an awful lot of technology out there that can drive operational
excellence, but the fact of the matter is that we have neglected
spending money on our assets outside automation,” says Smith.
There is no denying that even with extensive au tomation
investments, the marketplace still is overcome with legacy assets, but
this does not mean that it is impossible to capitalize on what current
software systems have to offer. Instead, Smith suggests that it points
to the glaring need to buy and implement more sensors that can
instrument what is already in place.
However, for
this to work, Smith says companies need to look ahead and do away with
the “break to fix” model. “This is where manufacturers would do well to
have handhelds complement the latest software to pick up information
from all of its assets. With this type of capturing in place, you start
to understand the performance information.”
Once
manufacturers understand these factors they can effectively bring the
“what if” scenarios into play. “The first step is to bring the process
into control, so that it is possible to understand the variable before
you start playing around with the data,” says Smith. “This is the only
way to effectively understand how to downplay constraints and do well
with your strengths, but you need to recognize your problem areas in
order to find the solutions.”
James Keane-Murphy of
Westchester, Ill.-based itelligence Inc. adds that throughout this
process manufacturers should attempt to rid themselves of what he
calls, “the relentless pursuit of the guilty.” “Sure the traceability
is what gives you the visibility as well as production support that
allows accurate decision making, but the system cannot be a dictator,”
he says. “Instead it should present proposed routes that you can either
accept or reject. Done right, these are what identify bottleneck
constraints that can ruin production schedules.” Warning signs
The
first step in selecting the most appropriate smart software is looking
for the warning signs pointing to shortfalls in existing systems. While
some signs may jump out, it is those that go unnoticed that can truly
wreak havoc on the bottom line.
The transactional
process versus real-time is one test for prospective software to pass,
says Matt Tormollen, CMO with Irvine, Tex.-based Pavilion Technologies.
“Does software provide the appropriate contact between the two levels
of data?” he asks. “Being able to provide real-time data as it relates
to a transaction is a basic requirement for success.
“For
instance, what comes to the plant level may include a lot of
characteristics that need to be identified and packaged so that the
order is not bogged down by the time it gets back to the ERP top level.
Even looking at performance measurement reporting if you define at one
line, one site, one plant, you need to make sure that the information
relates accurately.”
Kevin Dwyer, president and CEO
of Oakville, Ont.-based Shoplogix, agrees, adding that the when a
company embraces poor collection techniques it usually results in
discrepancies between recorded production information and actual
production numbers.
“How a business handles this
process (manually re-keying or embracing sensors combined with powerful
software tools) will unquestionably impact the accuracy of the data
used for decision making,” he says. “The attention a business pays to
this aspect ultimately impacts the financial well-being of the
business.”
When manufacturers experience problems in meeting customer demands it can signal a failure of the company’s software strategy.
According to Andre Pino, vice president and CMO of Marlton, N.J.-based
Acsis Inc., this often comes to light when RFID and compliance labeling
requirements mean implementing a separate point solution. “Capturing
data and effectively using it for the business should not be an
inefficient process that carries additional costs,” he says. “Instead,
you need to be able to respond to supply chain problems in a timely
fashion and avoid receiving complaints that you can’t tell a customer
the status of their order.”
Pino adds that when the solution is adequate, it should be relatively
easy to make improvements to the floor processes and business owners
will have a solid understanding of order flow throughout the
organization. “Otherwise the cost of capturing data in manufacturing
and warehousing increases and impacts profit margins, and it is quite
difficult to gain additional shop floor efficiency by automating
manufacturing processes.”
Businesses need to be able to pull data off of every machine that is
running a job or task on the plant floor. Such machine truths are
essential and can only come from devices connected directly to the
machine and independent of human intervention. Understandably, most
plants will have a very wide range of assets on the plant floor, but a
state of the art software product should easily address this disparate
or heterogeneous operating environment.
Connectivity also suggests that the data captured from each asset
should be easily aggregated and used to provide a consolidated view of
how well or poorly the plant is performing.
“Connectivity should also be extended to a variety of ancillary devices
like PDAs, pagers, cell phones, laptops, etc.,” says Dwyer. “This
automated connectivity enables proactive communications from the
machines on the plant floor with a variety of third party devices.
Proactive alarms and alerts regarding preventative maintenance, quality
issues, production statistics and other predetermined business rules
can easily be passed on to those that have a need to know.” Making the switch
Once
the decision has been made to invest in software, manufacturers need to
be aware that solutions are rarely turnkey and often require careful
consideration prior to committing money and time. According to
Tormollen, when upgrading, firms need to know that there is commonality
in their collection and aggregation of data regardless of which
software product it purchases. “This is what provides the metrics. A
lot of the information only goes to ERP as needed from a reporting
standpoint when needed,” he says. “You need to think about performance
and then enabling querying that allows management to ask intelligent
questions.”
Dave Gleditsch, CTO of Boulder, Colo.-based Pelion Systems also warns
about ignoring the adoption aspect. “When people do not trust, they do
not make sure that the data is fresh and consistent with what is really
going on,” he says. “You need to be able to effectively connect the
dots from information to the concrete improvements within the business
that really materialize into anything of significance.”
Upgrading is also the time to take a macro view of whether there is
more value stream as opposed to function thinking. “Can you view at a
macro level to provide information on a regular basis?” asks Gleditsch.
“You need to know that things are the way you need to view them, not
the way something forces you to view them.
This is all about the buy-in and acceptance that results in success. Is
the software flexible yet consistent? There needs to be flexibility
that meets needs while still having a solid level of standards that run
an operation in a positive and consistent manner. Performance
indicators and all the great data is vital, but you also need to be
able to look at the present and the future, not just the past to
accomplish these tasks.”
Despite the promises software developers offer up, most manufacturers
are smart enough to realize that no one solution will ever be the
elusive cure-all for its production woes. Yet, at the same time, it is
important to realize that the industry has made great strides, and that
with some impressive new capabilities they may at the very least
alleviate some of the pain. nanm Peter Fretty is a freelance writer and a regular contributor to Advanced Manufacturing. You can reach him at:
