Paper Converting Case Study
Effectively managing production at a paper converting facility with twelve
lines and over seven hundred unique products is a complex task. Different
case formats, product changeovers and staffing levels make determining
production efficiency difficult. This manufacturing facility needed
straightforward management tools to understand performance and to engage
everyone in the operation to improve it.
In a few short months, this converting operation improved line efficiency
by as much as 28% and plant-wide efficiency by 8% without adding more capital
or staff. In addition, quality improved and waste declined. They did it by
improving their execution.
This converting plant was faced with the same reality as the rest of the
industry; the need to lower unit costs and improve quality. To intensify the
situation, sales was applying pressure for smaller batches, which was
resulting in shorter runs and lots of changeovers.
Given currently invested capital, it was clear to senior management that
there was a gap between the current annual production of 2.7 million cases
and what was actually achievable. "We knew we had room to improve, but
we didn't have a good handle on the specifics," says the Production
Manager. "Scheduling pointed at the production group, production
pointed to maintenance and maintenance pointed at everyone. We wanted to
stop playing the blame game and get on with becoming more productive and
more profitable."
During a two week Assessment, Perforex determined that efficiency was 55%
of "theoretical maximum," giving the plant a large opportunity to
increase case production and decrease unit costs. Two key factors contributed
to the gap: management processes and managerial skill.
The first step was to determine if the right measures, targets and
reporting were in place to identify issues and drive performance improvement.
At first glance, it appeared that some of the right measures were in place;
Overall Equipment Efficiency (OEE) was in use, and downtime tracking forms
showed a lot of detail. Closer analysis however, uncovered some issues -
first, problems existed with OEE calculations, secondly, targets were not
updated and thirdly, no reconciliation was done to ensure that the eight
hours available per shift were accounted for by either earned production
hours or tracked downtime. As it stood, 25% of available hours were
unaccounted for.
Moving beyond the information available, the other key opportunity was
that of operating discipline. For example, during regular operational
reviews, poorly performing shifts were not scrutinized. A culture of
acceptance and/or blaming uncontrollables (i.e. paper quality) had taken over.
Another major opportunity identified was the effectiveness of the
infrastructure in place to manage the maintenance group. There were very few
tools and systems in place to plan, schedule and follow up on maintenance
work. There were no metrics in place to manage the group's performance.
Knowing that the answer could not be new capital or more people, management
engaged Perforex to design and implement improved management infrastructure
and develop managerial skill.
The first step towards closing the execution gap was to redesign the way
the converting lines and maintenance groups were managed. Together with
operators, millwrights, electricians and front-line supervisors, key
performance indicators (KPIs) were established, targets were set, evaluation
and reporting tools were developed and most importantly, an action planning
process was created.
Two key changes were made during the redesign process for the converting
lines. First, 'efficiency' was redefined to reflect the percentage of
theoretical maximum produced. Second, the importance of rigorously managing
'downtime' was clearly established. A straightforward set of tools was
designed and implemented to track efficiency and downtime on an hourly basis,
and identify opportunities for improvement.
"Accurate measurement and real-time performance management tools
take the grey area out... now we always know where the issue is, and are in
a much better position to address root causes."
On the maintenance side, business process redesign meant developing a series
of user-friendly tools to plan and execute work. Conceptually, all of these
tools were straightforward, the challenge was in working with staff to put them
to use in a disciplined and effective way.
Managing the maintenance department for performance was the next step.
Going beyond typical maintenance measures such as up-time percentages and
overtime costs, a complete set of performance indicators were developed.
Focusing on the specifics that the maintenance group actually controls
allowed them to look at their own performance more critically and take
steps to improve it.
Reporting and action-planning software was deployed to collect data, track
site-specific KPIs and generate user-friendly reports and graphs to
communicate performance information to all organizational levels. The
software also tracks action plan details and gives management the information
needed to communicate with shop-floor employees and monitor performance
improvement activity.
"Once the supervisors saw the benefits, they quickly jumped on
board" according to the Production Manager. "Accurate measurement
and real-time performance management tools take the grey area out. Now we
always know where the issue is, and we are in a much better position to
address root causes."
After four months of using the new management processes, annualized
production improved from 2.7 to 2.9 million cases. "These gains aren't
the result of one or two big hit items. They came from improving product
scheduling, product quality, waste, maintenance, parts management, and a host
of other items," says the Production Manager. In addition, improved
efficiency has given management more flexibility around product runs and
staffing configurations.
The Assistant Production Manager is impressed with the qualitative
results and tangible benefits, "We used to be constantly firefighting.
Now we know the detail of what's happening on the shop floor and operators
understand what is expected in terms of activities and ultimately performance.
We have finally taken control of our manufacturing process."
