CTR IMPROVES BUSINESS PERFORMANCE

The following scenarios of lost productivity should be familiar to
anyone with even a little experience managing manufacturing operations.
- The company can’t meet delivery dates, no matter how much it
tinkers with lead times.
- Operators always have a backlog, regardless of the production
schedule.
- One rush order from a major customer throws the whole week’s
production schedule out of kilter.
- The finished product warehouse is bulging, in part with items
customers no longer want.
Each
of these scenarios takes a bite out of a company’s productivity. The sum
of these productivity losses adds up to a major waste of resources that
could otherwise be used to improve customer service, increase revenues
or enhance the company’s competitiveness.
One management tool that has proven successful at eliminating waste and
improving performance at small and mid-sized manufacturers is Cycle Time
Reduction (CTR). CTR consists of speeding up a company’s order-to-delivery
time to get product into the customer’s hands as quickly as possible,
at the lowest possible cost. It’s a way of looking critically at a company’s
business processes—from order entry to cheduling to inventory management
and shipping—to find opportunities to squeeze more efficiency out
of them.
Successful CTR typically produces manufacturing improvements that can
easily be quantified. Some of the results in CTR projects that the authors
have been involved in are:
- 60 - 90 percent reduction in lead time
- 30 - 50 percent reduction in manufacturing floor space
- 40 - 80 percent reduction in total quality cost
- 50 - 90 percent reduction in setup times and lot sizes
- 95 - 100 percent of promises met on every shift.
Probable Cause
There may be several causes of a manufacturer’s long order-to-delivery
cycle. Often a problem early in the cycle triggers other problems down
the line, snowballing into days of delay. Here are four common factors
that can stretch the order-to-delivery cycle:
- Too many non-value-added activities. At most companies, the time
an order is actually being worked on averages less than five percent
of the order-to-delivery cycle. Inventory thus spends 95 percent of
the time between order entry and shipment waiting for the next step
in the process. Complicated paperwork and long waits during the work
process can add days to the cycle, but no value to the product.
- Measuring the wrong parameters. Often companies measure their performance
against criteria such as equipment utilization, productivity or order
completion date and think they’re doing fine if they get high scores.
But a company can excel by these criteria and still lose out to the
competition if it can’t get its product to the customer when it promised.
Employees perform to what’s being measured.
- Capacity management. The balancing of customer demand and available
capacity is essential to success. This is not to say a company should
refuse orders, but rather that it realizes it must meet delivery commitments
that satisfy customers.
- Corporate culture. Employee attitudes toward work can have an adverse
effect on performance. At one manufacturer, for example, some shop floor
personnel developed the habit of never emptying their bins by the end
of day. No matter how much time they were given, they were consistently
behind. They confessed that having work waiting for them the next morning
increased their sense of job security. Not only was the manufacturer
doing a sloppy job of managing production, it also failed to communicate
corporate values and objectives.
The
way a manufacturer manages its inventory can be a key indicator of its
efficiency and a prime target for analysis to uncover the factors that
contribute to poor delivery performance. At many manufacturers, inventory-whether
raw material, work in process or finished goods-is a buffer against inefficient
planning, long setup times, poor product quality and inability to deliver
on time. Companies keep inventory around "just in case." Yet
excess inventory indicates that the company is not doing a good job of
matching production to current customer demand. Also, it ties up cash.
Reducing inventory is an effective way to expose hidden production management
problems.
Principles of CTR
There is no one-size-fits-all answer to the problem of long cycle times.
A company has to identify the bottlenecks specific to its operations,
devise solutions, set realistic goals, and develop a plan to achieve them.
There are, however, some fundamental principles underlying successful
CTR:
Make only what the customer wants when the customer wants it. That means
letting orders drive the manufacturing schedule. To take it to an extreme,
what a company shipped yesterday is what it should make today, because
that’s what its customers want. Lot sizes will shrink, because a company
won’t be ganging jobs or stockpiling for future orders.
Reduce inventory throughout the cycle-especially work in process and finished
goods inventories. That means that your suppliers must be able to meet
your on-time delivery requirements so that you have just enough of what
you need when you need it. You have to schedule production to work to
capacity without permitting backlogs.
Set goals and measure performance against benchmarks that matter to the
customer-for instance, on-time delivery, number of returns, price compared
to the competition. The goals should be based not on your company’s past
performance, but on what the best companies in the industry are achieving,
because those are your competitors.
CTR gives a manufacturer a way to identify and eliminate the causes of
the scenarios mentioned earlier by giving it a framework for:
- Balancing orders with capacity, so it doesn’t promise what it
can’t deliver
- Eliminating backlogs in work in process, so that every order
can be processed expeditiously
- Basing production on current demand, so product doesn’t pile
up in the warehouse waiting for orders
- Creating an environment where management and employees work toward
common objectives.
An objective, outside analysis by a consultant experienced in manufacturing
management can ensure the success of a CTR initiative. The consultant
can work with management to analyze the company’s processes and develop
goals and a plan. Equally important, the consultant can work with employees
to listen to their suggestions, communicate them to management and identify
and allay employees’ concerns over change.
Small and mid-sized manufacturer in the current competitive—and
increasingly global—marketplace are seeking ways to differentiate
themselves from their competitors. CTR is an effective, proven way to
give a manufacturer a competitive edge in price, quality, lead time and
on-time delivery.
CTR is an on-going process that takes a strong management commitment.
Change can be difficult, but a manufacturer that keeps doing the same
things will keep getting the same results. S!
